2 * Added PNG:compression_level, compression_strategy, and compession_filter
3 defines to the PNG encoder. If these defines are used, they take
4 precedence over the -quality option.
6 2011-06-30 6.7.0-10 Cristy <quetzlzacatenango@image...>
7 * New version 6.7.0-10.
9 2011-06-29 6.7.0-7 Glenn Randers-Pehrson <glennrp@image...>
10 * Handle "-quality 97" properly in the png encoder, .e., to use
11 intrapixel filtering when writing a MNG file. and no filtering when
13 * Added support for Z_RLE strategy in the png compressor, using
16 2011-06-28 6.7.0-10 Cristy <quetzlzacatenango@image...>
17 * Properly allocate points when render text with large font size (reference
18 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18997).

31 Includes derivative (scaled lookup), and anti-aliased horizon (validity)
32 Currently can NOT handle extractions from full 360 cylinder panoramas.
34 2011-06-13 6.7.0-7 Cristy <quetzlzacatenango@image...>
35 * New version 6.7.0-7.
37 2011-06-09 6.7.0-7 Cristy <quetzlzacatenango@image...>
38 * Fixed "conversion from unsigned __int64 to double not implemented"
39 so IM can compile under VisualStudio 6.
41 2011-06-08 6.7.0-7 Glenn Randers-Pehrson <glennrp@image...>
42 * The PNG encoder would sometimes make black pixels transparent when some
43 other gray level was supposed to be the transparent color (reference
44 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18900).
45 This occurred only with 1, 2, 4-bit grayscale images with Q16 or Q32
48 2011-06-08 6.7.0-6 Cristy <quetzlzacatenango@image...>
49 * New version 6.7.0-6.
51 2011-06-08 6.7.0-6 Cristy <quetzlzacatenango@image...>
52 * Fix transient error for composite over operator.
54 2011-06-07 6.7.0-5 Cristy <quetzlzacatenango@image...>

57 2011-06-07 6.7.0-5 Cristy <quetzlzacatenango@image...>
58 * Fix one-off bug in option parser (reference
59 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=609177).
60 * Transient bug with composite over in magick/composite-private.h.
62 2011-06-06 6.7.0-4 Cristy <quetzlzacatenango@image...>
63 * New version 6.7.0-4.
65 2011-06-03 6.7.0-4 Cristy <quetzlzacatenango@image...>
66 * Support -direction right-to-left for the label: and caption: coders.
67 * Blue / green reversed for JPEG-compressed TIFF images.
69 2011-06-03 6.7.0-3 Cristy <quetzlzacatenango@image...>
70 * New version 6.7.0-3.
72 2011-06-02 6.7.0-2 Cristy <quetzlzacatenango@image...>
73 * Use memmove() instead of memcpy() in StripString().
75 2011-05-27 6.7.0-2 Cristy <quetzlzacatenango@image...>
76 * New version 6.7.0-2.
78 2011-05-26 6.7.0-2 Cristy <quetzlzacatenango@image...>
79 * ImageMagick now compiles on Hurd (reference
80 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=628020).
81 * Use vfprintf rather than fprintf in FormatLocaleFileList().
83 2011-05-26 6.7.0-1 Cristy <quetzlzacatenango@image...>
84 * New version 6.7.0-1.
86 2011-05-25 6.7.0-1 Cristy <quetzlzacatenango@image...>
87 * Not all Linux'es define locale_t (reference
88 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18819).

99 2011-05-20 6.6.9-10 Cristy <quetzlzacatenango@image...>
100 * New version 6.6.9-10.
102 2011-05-20 6.6.9-10 Glenn Randers-Pehrson <glennrp@image...>
103 * The PNG encoder now respects the -depth setting, including 1, 2, 4.
104 Previously settings other than 8 and 16 were ignored (reference
105 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18412).
107 2011-05-16 6.6.9-10 Cristy <quetzlzacatenango@image...>
108 * Don't use comma as a separator for stroked text (reference
109 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18742).
110 * Use C locale when generating or interpretting SVG.
111 * Fix "unterminated macro" for Q32 build of coders/png.c.
113 2011-05-15 6.6.9-9 Cristy <quetzlzacatenango@image...>
114 * New version 6.6.9-9.
116 2011-05-14 6.6.9-9 Cristy <quetzlzacatenango@image...>
117 * The -scale option now considers the alpha channel when scaling.
118 * Fix transient bug for HSL to RGB and back.
120 2011-05-12 6.6.9-9 Glenn Randers-Pehrson <glennrp@image...>
121 * Fixed PNG8 reduction to work with an image that reduces to 256 colors
122 plus transparency, by merging the two darkest red colors.
124 2011-05-04 6.6.9-8 Cristy <quetzlzacatenango@image...>
125 * New version 6.6.9-8.
127 2011-05-02 6.6.9-8 Glenn Randers-Pehrson <glennrp@image...>
128 * Fixed some cut-and-paste errors in new png.c code that caused PNG8
131 2011-05-02 6.6.9-8 Anthony Thyssen <A.Thyssen@griffith...>
132 * Add various Option Flags, and fix option skip counts for plus forms
133 of simple operators where plus form is the same as minus form.
134 For example the incorrect counts produces a weird error, and possible
135 future segmentation fault in a command like convert rose: +border show:
137 2011-04-30 6.6.9-7 Cristy <quetzlzacatenango@image...>
138 * New version 6.6.9-7.
140 2011-04-30 6.6.9-7 Anthony Thyssen <A.Thyssen@griffith...>
141 * Fix FX default for interpolation to Bilinear.
143 2011-04-27 6.6.9-7 Cristy <quetzlzacatenango@image...>
144 * Fix pixel interpolation for -draw image over (reference
145 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18612).
147 2011-04-26 6.6.9-7 Glenn Randers-Pehrson <glennrp@image...>
148 * Write the proper bKGD chunk value in grayscale PNG images (reference
149 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18624).
151 2011-04-25 6.6.9-7 Anthony Thyssen <A.Thyssen@griffith...>
152 * Added Inverse method for Sparse Color Interpolation
154 2011-04-24 6.6.9-6 Cristy <quetzlzacatenango@image...>
155 * New version 6.6.9-6.
157 2011-04-21 6.6.9-6 Anthony Thyssen <A.Thyssen@griffith...>
158 * Make filter:blur define a multiplicative adjustment of filter settings
159 rather than a complete override of those settings.
160 * Add Flags to CommandOptions parse table, removing the need for
161 ImageListOptions parsing table. This is the start of development to
162 produce a "convert" replacement that can read options from both command
163 line and from files or pipelines, in "Do it Immediately" handling.
164 * Crop Bug Fix. Prevent infinite loop with "+repage -crop 0x40"
166 2011-04-18 6.6.9-6 Glenn Randers-Pehrson <glennrp@image...>
167 * Added "date" to the things that can appear on the -define PNG:exclude-chunk
168 list. This excludes the IM-generated Date:modify and Date:create
169 properties from PNG output text chunks without excluding the rest of the
171 * Added "-define PNG:preserve-colormap" option (reference
172 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18564).
173 * Simplified LosslessReduceDepthOK() function in coders/png.c
175 2011-04-18 6.6.9-6 Cristy <quetzlzacatenango@image...>
176 * Add support for writing RGB FITS images as separate planes.
178 2011-04-16 6.6.9-6 Cristy <quetzlzacatenango@image...>
179 * Support the HDR 32-bit_rle_xyze format.
180 * Fixed infinite loop for TARGA images with a V2 develop area.
181 * Add signal handler for SIGBUS.
183 2011-04-15 6.6.9-5 Cristy <quetzlzacatenango@image...>
184 * New version 6.6.9-5.
186 2011-04-15 6.6.9-5 Glenn Randers-Pehrson <glennrp@image...>
187 * Added "#define PNG_PTR_NORETURN" because this macro does not work
188 on all platforms with libpng15, with failure to load png_longjmp() (ref
189 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18518).
191 2011-04-14 6.6.9-5 Anthony Thyssen <A.Thyssen@griffith...>
192 * Layers Composition Bug Fix, animations attributes of first image not
193 transferred in a single destination, multi-source image composition.
195 2011-04-09 6.6.9-5 Anthony Thyssen <A.Thyssen@griffith...>
196 * Add a special 'Voronoi' Morphology Distance method that will fill in holes
197 using the nearest non-transparent edge pixel. It is experimental, and
198 hidden from normal morphology usage, as it may be interfaced with a
199 future hole-filling color 'Diffusion' method.
201 2011-04-08 6.6.9-5 Cristy <quetzlzacatenango@image...>
202 * MIFF keywords sometimes includes spaces.
204 2011-04-07 6.6.9-5 Anthony Thyssen <A.Thyssen@griffith...>
205 * Major BUG FIX - wrong sign breaks most morphology methods in IM v6.6.9-4
206 * Fixed -region handling of transparency. Original images without
207 transparency will use 'Over' while images with transparency will
208 preserve transparency using 'Copy'. Before this only 'Over' was used
209 due to the testing of the wrong image.
210 * Added Compose methods DarkenIntensity and LightenIntensity
212 2011-04-06 6.6.9-4 Cristy <quetzlzacatenango@image...>
213 * New version 6.6.9-4.
215 2011-04-03 6.6.9-4 Anthony Thyssen <A.Thyssen@griffith...>
216 * Add Octagon shape and Octagonal distance kernels for Morphology
217 * Fix minor Morphology kernel compose bug (cleanup after Src/Dst swap)
218 * Fix segmentation fault after error in a morphology 'named' kernel
219 * Added a range of kernels used for specialised thinning purposes
220 as defined in a research paper by Dan S. Bloomberg.
221 * Added Dan Bloomberg best thinning skeletion, "Skeleton:3"
222 * Removed origin pixel from many Hit-and-Miss kernels allowing kernels
223 to not only be used for thinning, but also thickening.
224 * Renamed "ThinDiagonals" kernel to just "Diagonals"
225 * Distance uses a fast two pass algorithm, and no longer needs 'iteration'
227 2011-04-02 6.6.9-4 Glenn Randers-Pehrson <glennrp@image...>
228 * Make the PNG encoder use depth==8 when incoming image->depth < 8
229 (the encoder later reduces the depth if it can), to avoid writing
231 * Remove any bogus colormap received by the PNG encoder with an image
232 that is not PseudoClass (reference
233 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18475).
235 2011-04-02 6.6.9-3 Cristy <quetzlzacatenango@image...>
236 * Added -statistic Gradient
238 2011-04-01 6.6.9-3 Cristy <quetzlzacatenango@image...>
239 * New version 6.6.9-3.
241 2011-04-01 6.6.9-3 Cristy <quetzlzacatenango@image...>
242 * Set the caption height correctly for missing row geometry (reference
243 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18447).
245 2011-03-31 6.6.9-2 Cristy <quetzlzacatenango@image...>
246 * New version 6.6.9-2.
248 2011-03-30 6.6.9-2 Glenn Randers-Pehrson <glennrp@image...>
249 * Revised the png decoder to store the PNG IHDR and other known PNG
250 chunk data as properties, for later retrieval and reporting by "identify",
251 so users can easily and reliably discover the color-type, bit-depth, etc
252 that were in the input PNG datastream.
253 * The PNG decoder sometimes set images with more than 256 different
254 gray-alpha pixels to storage_class=PseudoClass with an incorrect colormap.
256 2011-03-30 6.6.9-2 Anthony Thyssen <A.Thyssen@griffith...>
257 * Add a "Resize" distortion method (distort equivalent of -resize).
258 * Special CLI handling so -distort Resize takes a "geometry" argument.
260 2011-03-29 6.6.9-2 Cristy <quetzlzacatenango@image...>
261 * Expand PCL compressed pixel buffer to prevent delta compressed overrun.
263 2011-03-29 6.6.9-1 Cristy <quetzlzacatenango@image...>
264 * New version 6.6.9-1.
266 2011-03-29 6.6.9-1 Anthony Thyssen <A.Thyssen@griffith...>
267 * Fix AdaptiveResizeImage() to use 'Mesh' Interpolation, and fix its
268 coordinate handling, as originally defined.
270 2011-03-29 6.6.9-1 Cristy <quetzlzacatenango@image...>
271 * Support -statistic standard-deviation option.
272 * Patch for coders/dcm.c so it compiled with HDRI enabled.
274 2011-03-28 6.6.9-0 Cristy <quetzlzacatenango@image...>
275 * New version 6.6.9-0.
277 2011-03-28 6.6.9-0 Cristy <quetzlzacatenango@image...>
278 * Optimize bilinear interpolation.
279 * Remove version from etc folder and instead use /etc/ImageMagick.
281 2011-03-28 6.6.9-0 Anthony Thyssen <A.Thyssen@griffith...>
282 * Separated complex cropping function from TransformImage() as a new
283 function CropImageToTiles(). This new function returns either the
284 new cropped image, or a list of tiles, according to geometry, without
285 replacing the source image. The Source image may be part of a larger list
286 of images, without the function 'losing' the other images of the list.
288 2011-03-27 6.6.8-10 Cristy <quetzlzacatenango@image...>
289 * New version 6.6.8-10.
291 2011-03-27 6.6.8-10 Anthony Thyssen <A.Thyssen@griffith...>
292 * Modified image handling in MogrifyImages() and MogrifyImage()
293 which improves overall handling, and allows correct %p, %n and the
294 %[fx:..] 't' and 'n' escape usage to work correctly.
295 * Added -duplicate as a multi-image sequence operator
297 2011-03-26 6.6.8-9 Cristy <quetzlzacatenango@image...>
298 * New version 6.6.8-9.
300 2011-03-25 6.6.8-9 Cristy <quetzlzacatenango@image...>
301 * Add InterpolateMagickPixelPacket() method.
302 * Add support for the %[opaque] property.
304 2011-03-25 6.6.8-8 Cristy <quetzlzacatenango@image...>
305 * New version 6.6.8-8.
307 2011-03-25 6.6.8-8 Cristy <quetzlzacatenango@image...>
308 * Fix memory access bug in CloneString() (reference
309 http://www.imagemagick.org/discourse-server/viewtopic.php?f=2&t=18382).
310 * Avoid infinite loop when no space is available in MagickFormatCaption().
312 2011-03-25 6.6.8-8 Anthony Thyssen <A.Thyssen@griffith...>
313 * Removed the fix for %p and %n escapes, as it was not working right
315 2011-03-24 6.6.8-7 Cristy <quetzlzacatenango@image...>
316 * New version 6.6.8-7.
318 2011-03-24 6.6.8-7 Cristy <quetzlzacatenango@image...>
319 * Add support for 16-bit DCM short ints (reference
320 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18371).
322 2011-03-23 6.6.8-7 Anthony Thyssen <A.Thyssen@griffith...>
323 * Another fix for -sparse-color and unused color channels
324 * Finalize the -duplicate option created by Cristy
325 * Fix of segmentation fault for second image in %[fx:..] during info:
326 (Bug in AcquireFxInfo(), as given start image is not first image)
328 2011-03-21 6.6.8-7 Glenn Randers-Pehrson <glennrp@image...>
329 * Revised the PNG8 encoder to use 50% threshold instead of 0% when
330 reducing transparency to binary. Collapse all resulting fully transparent
331 colors into one (the background color), to reduce the compressed filesize.
332 * First try the 4-4-4-1 and 3-3-3-1 palettes instead of 3-3-2-1, to preserve
333 colors (especially gray) better, when reducing to PNG8.
334 * Force the PNG encoder to return image->matte==MagickTrue when the
335 format is RGBA or GA or if the tRNS chunk is present, even when the
336 image is fully opaque (reference
337 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18349).
339 2011-03-21 6.6.8-6 Cristy <quetzlzacatenango@image...>
340 * New version 6.6.8-6.
342 2011-03-21 6.6.8-6 Glenn Randers-Pehrson <glennrp@image...>
343 * Re-enabled reduction of grayscale images (color-type 0) to 2 or 4 bits
344 when appropriate (reference
345 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18098).
346 * The "-define PNG:color-type=4" option did not always force the PNG
347 encoder to write an all-opaque alpha channel (reference
348 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18349).
350 2011-03-14 6.6.8-6 Cristy <quetzlzacatenango@image...>
351 * Fixed memory leak for PDF and Bitmap PSD RLE support (reference
352 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18317).
353 * Support the -statistic option: replace each pixel with corresponding
354 statistic from the neighborhood.
355 * Add support for -duplicate option.
356 * Move configuration files from /usr/share and /usr/lib to /etc and /var.
357 * Do not cache the results of fx: otherwise -format
358 '%[fx:rand()] %[fx:rand()]' returns the same random numbers.
360 2011-03-18 6.6.8-6 Anthony Thyssen <A.Thyssen@griffith...>
361 * Replaced Minus and Divide Composition methods with Dst and Src
362 equivalents. Now users can decide how these non-commutative mathematical
363 operators are applied to the images being composited.
364 * Fix the percent escape values for %p, %n and %[fx:t], %[fx:n] to
365 respectively mean the current images index and the total number of
366 images within the current image sequence.
368 2011-03-17 6.6.8-5 Anthony Thyssen <A.Thyssen@griffith...>
369 * Backed out the patch for Variable Blur Composition that was added
370 2011-02-13 v6.6.7-7, until I can re-think the problem.
371 The existing fix was failing to do circular blurs correctly.
373 2011-03-14 6.6.8-5 Glenn Randers-Pehrson <glennrp@image...>
374 * Fixed a rounding/truncation error while writing the pHYs chunk in the
376 * Don't write text-encoded profile when "-define PNG:exclude-chunk=text,ztxt"
377 is present (reference
378 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17086 and
379 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18225).
381 2011-03-14 6.6.8-5 Cristy <quetzlzacatenango@image...>
382 * Add support for the WebP image format.
384 2011-03-14 6.6.8-5 Anthony Thyssen <A.Thyssen@griffith...>
385 * Ensured that -sparse-color preserves unused channels when
386 channel limited. Before this unused channels would be reset to black.
388 2011-03-11 6.6.8-4 Glenn Randers-Pehrson <glennrp@image...>
389 * Don't try to store a bKGD chunk in a PNG8 when there are already
390 256 colors in the palette and the background colors is not in that
392 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18199);
393 * The "-define PNG:exclude-chunk=bKGD" option was also excluding
394 the text chunks. (reference
395 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18253).
397 2011-03-10 6.6.8-4 Cristy <quetzlzacatenango@image...>
398 * Fx is a mathematical function. Do not treat transparency as black.
399 * No image scene suffix for filenames that include a single bracket (reference
400 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18267).
402 2011-03-10 6.6.8-3 Cristy <quetzlzacatenango@image...>
403 * New version 6.6.8-3.
405 2011-03-10 6.6.8-3 Cristy <quetzlzacatenango@image...>
406 * Boost causes an ambiguity with ssize_t when building PythonMagick. Add
407 patch from Arfrever@gento... to fix the build exception.
409 2011-03-09 6.6.8-2 Cristy <quetzlzacatenango@image...>
410 * Support the Radiance HDR image format.
411 * Update the offset in the black channel when sharpening to avoid incorrect
413 * Do not use GenericReadMethod for TIFF images with 64-bits per sample.
415 2011-03-06 6.6.8-2 Glenn Randers-Pehrson <glennrp@image...>
416 * Throw error message when the requested color-type or bit-depth
417 cannot be written by the PNG encoder (error was being thrown
418 into the wrong image structure). (Reference
419 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18162).
420 * Don't write a PNG text chunk with "density" keyword that overrides the
421 PNG pHYs chunk, if the pHYs chunk was not excluded (reference
422 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18253).
423 * Ignore any PNG text chunk with a "density" keyword found by the PNG
424 decoder, if the PNG datastream also contains a pHYs chunk.
426 2011-03-06 6.6.8-1 Cristy <quetzlzacatenango@image...>
427 * New version 6.6.8-1.
429 2011-03-05 6.6.8-1 Cristy <quetzlzacatenango@image...>
430 * Support PSD files with one layer and one composite layer.
431 * We must cast a Quantum type when bit shifting and HDRI is enabled.
433 2011-03-05 6.6.8-0 Cristy <quetzlzacatenango@image...>
434 * New version 6.6.8-0.
436 2011-02-27 6.6.8-0 Cristy <quetzlzacatenango@image...>
437 * Add support for the -mode option.
439 2011-02-27 6.6.8-0 Glenn Randers-Pehrson <glennrp@image...>
440 * Fix scaling of new color-reduction method in the PNG encoder (16-bit
441 images were scaled down to 0 or 1, or nearly black).
442 * Delay opening the PNG output blob until the PNG encoder is ready
443 to write the IHDR chunk, to avoid writing zero-length PNG files when
444 errors are found while building the palette. (reference
445 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18162).
447 2011-02-25 6.6.7-10 Cristy <quetzlzacatenango@image...>
448 * New version 6.6.7-10.
450 2011-02-23 6.6.7-10 Cristy <quetzlzacatenango@image...>
451 * Avoid seg fault in AppendImages() when one image is in the RGB colorspace
452 but the other is in the CMYK colorspace.
453 * Get rid of 'respect_parenthesis defined but not used' warnings (reference
454 http://www.imagemagick.org/discourse-server/viewtopic.php?f=2&t=18173).
456 2011-02-22 6.6.7-10 Glenn Randers-Pehrson <glennrp@image...>
457 * Write sub-8-bit grayscale PNG images as palette-indexed PNG images. This
458 usually makes smaller files anyhow.
459 * Eliminated a number of redundant tests for gray images in the PNG encoder.
460 * Removed now-unused IsMonochromeImage() function from coders/png.c
461 * Scan the colormap instead of all of the pixels, when possible, to
462 determine whether the image received by the PNG encoder is grayscale
464 * Avoid reading from the colormap in coders/png.c when it is NULL (reference
465 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18162).
466 * Add a check whether the PNG "cheap transparency" criteria are met. That
467 is, there is a single transparent color, no semitransparent colors, and
468 no opaque color that has the same RGB components as the transparent
469 color. If those aren't met, a color that is transparent in one pixel
470 and opaque in another would always be rendered as transparent, so we
471 must write a PNG colortype that has an alpha channel (reference
472 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18167).
474 2011-02-22 6.6.7-9 Cristy <quetzlzacatenango@image...>
475 * New version 6.6.7-9.
477 2011-02-22 6.6.7-9 Glenn Randers-Pehrson <glennrp@image...>
478 * Disabled reduction of grayscale images (color-type 0) to less than 8 bits
479 when writing because this sometimes produced incorrect output (reference
480 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18098).
482 2011-02-21 6.6.7-9 Cristy <quetzlzacatenango@image...>
483 * Check image has properties before accessing the splay tree (reference
484 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18136).
486 2011-02-15 6.6.7-8 Cristy <quetzlzacatenango@image...>
487 * New version 6.6.7-8.
489 2011-02-14 6.6.7-8 Glenn Randers-Pehrson <glennrp@image...>
490 * The PNG encoder should ignore bogus q->opacity values when image->matte
491 is MagickFalse (reference
492 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18067).
494 2011-02-14 6.6.7-8 Cristy <quetzlzacatenango@image...>
495 * Use implicit image format when explicit format is bogus (e.g.
496 02.13.11-18:43:58.png now writes as PNG).
497 * Fix problem with 4GB file seeks on a 32-bit OS.
499 2011-02-13 6.6.7-7 Anthony Thyssen <A.Thyssen@griffith...>
500 * Fixed Variable blur to handle small (< 1.0 sigma) blurs generated
501 by the blur map being used, rather than just 'cutoff' suddenly.
503 2011-02-08 6.6.7-7 Cristy <quetzlzacatenango@image...>
504 * Support 16-bit per pixel YUV image files.
505 * Fix off-by-one error in PosterizeImage().
506 * Posterize now distributes color uniformly (reference
507 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17623).
508 * Add -smush option (reference
509 http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=17953).
510 * Repair memory leak in the display program.
512 2011-02-07 6.6.7-6 Cristy <quetzlzacatenango@image...>
513 * Fix bug in carg() define when HAVE_COMPLEX is not defined (reference
514 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18030).
516 2011-02-06 6.6.7-6 Anthony Thyssen <A.Thyssen@griffith...>
517 * Default sigma for Gauusian resize filter is now 1/2 for both
518 orthogonal resize and cylindrical EWA distortions.
520 2011-02-02 6.6.7-5 Cristy <quetzlzacatenango@image...>
521 * Check if the font is null in RenderFreetype() to prevent fault (reference
522 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17890).
523 * Eliminate fault when reading WMF image files (reference
524 http://www.imagemagick.org/discourse-server/viewtopic.php?f=2&t=17971).
525 * Support multi-page transparent Postscript and PDF image files.
526 * The compare fuzz metric now returns the same correct value for
527 'xc:white xc:blue -alpha off' and 'xc:white xc:blue -alpha on'.
529 2011-01-29 6.6.7-4 Paul Heckbert <ph@cs.cm...>
530 * Move coders/tiff.c conditional compile to define TIFF exception /
531 semaphore / key when TIFF delegate is disabled.
533 2011-01-29 6.6.7-4 Glenn Randers-Pehrson <glennrp@image...>
534 * Renamed variables, macros, and functions defined/declared in coders/png.c
535 that were in the libpng namespace (beginning with "png_" or "PNG_").
537 2011-01-25 6.6.7-3 Glenn Randers-Pehrson <glennrp@image...>
538 * Removed a call to GetNumberColors() from the PNG encoder that was
539 only there for debugging purposes and was consuming a huge amount
540 of CPU time. (reference
541 http://www.imagemagick.org/discourse-server/viewtopic.php?f=2&t=17799).
542 * Sometimes black was still written as transparent, when the PNG
543 encoder received an image with image->matte==true but no transparent
544 pixels were present. (reference
545 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17913);
547 2011-01-24 6.6.7-3 Cristy <quetzlzacatenango@image...>
548 * Remove memory leak from ThrowFileException() macro (reference
549 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17908).
550 * Multiple blue error count by 'count' in ClassifyImageColors()
551 * Add support for the AAI image format.
553 2011-01-22 6.6.7-2 Cristy <quetzlzacatenango@image...>
554 * Accept quoted file paths in indirect file references (e.g. @myFiles.txt).
556 2011-01-19 6.6.7-2 Glenn Randers-Pehrson <glennrp@image...>
557 * Changed the PNG encoder's "transparent_color" from a UShortPixelPacket
558 to LongPixelPacket and made the default (65537,65537,65537), which
559 can never occur in the PNG image data. Previously the default was
560 (0,0,0) and black pixels would be rendered as as transparent when
561 no tRNS chunk was present in the input, which has caused problems
562 with some test cases since version 6.6.6-10.
563 * Improved the PNG_BUILD_PALETTE section to count opaque, transparent,
564 and semitransparent pixels separately. Previously it wasn't always
565 possible to determine if there was a single fully-transparent color,
566 to decide whether to write an RGBA or Gray-Alpha image or an RGB or
567 Gray image with a tRNS chunk.
569 2011-01-15 6.6.7-1 Cristy <quetzlzacatenango@image...>
570 * Do not reset image next / previous when detach argument is false for
572 * Inline cropping no longer fails for inline raw images (e.g.
573 -size 640x480 -depth 8 'gray:logo[100x100+200+200]').
575 2011-01-14 6.6.7-1 Glenn Randers-Pehrson <glennrp@image...>
576 * Don't let the PNG encoder try to sort the colormap when there are more
577 than 256 colors in the image. (reference
578 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17834).
580 2011-01-10 6.6.7-1 Cristy <quetzlzacatenango@image...>
581 * Accept escaped % in output filename (reference
582 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17810).
584 2011-01-08 6.6.7-1 Glenn Randers-Pehrson <glennrp@image...>
585 * Quieted some inconsequential warnings in the PNG codec due to a
586 change in the type of the PNG iCCP profile from png_charp to png_bytep
589 2011-01-03 6.6.7-0 Cristy <quetzlzacatenango@image...>
590 * Handle negative heights for ICO images.
592 2011-01-02 6.6.7-0 Glenn Randers-Pehrson <glennrp@image...>
593 * Recent changes sometimes caused the PNG encoder to select colortype=2
594 (Truecolor) instead of 0 (Grayscale) for grayscale images. This made
595 the filesize larger than necessary and caused some of the PerlMagick
598 2011-01-01 6.6.6-10 Glenn Randers-Pehrson <glennrp@image...>
599 * The PNG decoder now checks whether the image actually has any transparency
600 when the input file contains an alpha channel or a tRNS chunk. (Reference
601 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17748)
603 2010-12-26 6.6.6-8 Cristy <quetzlzacatenango@image...>
604 * -posterize fails with more than 40 levels (reference
605 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17741).
606 * Add support for the MacPaint image format.
607 * Eliminate spurious 'invalid colormap index' exception for 16-bit SGI images
608 (bug report by steven.sittser@fligh...).
609 * Fix user data length for the CIN image format.
611 2010-12-21 6.6.6-7 Glenn Randers-Pehrson <glennrp@image...>
612 * Use a clone instead of the main image in coders/png.c, so the image
613 can still be used later on without being affected by changes made by
615 * Added PNG:exclude-chunk and PNG:include-chunk defines.
616 * Revised the -strip option so it behaves as though
617 "-define PNG:include-chunk=none,gama" had appeared on the commandline.
618 * Avoid writing PNG ancillary chunks in the PNG/MNG/JNG encoder while
619 generating the alpha channel for a JNG image.
621 2010-12-21 6.6.6-7 Anthony Thyssen <A.Thyssen@griffith...>
622 * Removed the forced interpolation setting in AcquireResampleFilterThreadSet
623 It prevented user defined interpolation settings for -clut, and possibly
626 2010-12-17 6.6.6-6 Chris Madison <madisonblu@gmail...>
627 * Add LZMA compression support to ImageMagick.
628 * Eliminate seg-fault in MvgPrintf().
630 2010-12-17 6.6.6-6 Glenn Randers-Pehrson <glennrp@image...>
631 * Eliminated a redundant quantization step in the PNG encoder.
632 * Untangled a confusing but apparently harmless improper loop nesting
634 * Eliminated redundant "IsGray()" tests from the PNG encoder.
636 2010-12-14 6.6.6-6 Cristy <quetzlzacatenango@image...>
637 * -format "%[fx:u.p{5,5}]" no longer reports parse exception (reference
638 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17678).
640 2010-12-10 6.6.6-5 Glenn Randers-Pehrson <glennrp@image...>
641 * Make the PNG encoder always rebuild the palette, to avoid losing
642 transparency when it is out of sync with the pixel data (reference
643 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17655).
644 * Eliminated CompressColormapTransFirst() since the palette is already
645 compressed and sorted by opacity now when it's recreated.
647 2010-12-10 6.6.6-5 Cristy <quetzlzacatenango@image...>
648 * Account for virtual canvas for the -flip / -flop options (reference
649 http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=17626).
650 * Also for -transpose and transverse options
651 * Support -metric fuzz option.
653 2010-12-09 6.6.6-4 Anthony Thyssen <A.Thyssen@griffith...>
654 * Replace IsMagickColorSimilar() which provides the Fuzz Factor threshold
655 function. Note function does not calculate 'distance' in total but
656 short-circuits when threshold is reached for faster processing.
657 * Ordered Dithered handling of Alpha channel was incorrect - fixing
658 Bug was introduced v6.6.5-6
660 2010-12-03 6.6.6-3 Glenn Randers-Pehrson <glennrp@image...>
661 * Fixed two more cases where the PNG encoder lost transparency (reference
662 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17516).
664 2010-12-01 6.6.6-2 Cristy <quetzlzacatenango@image...>
665 * Affine multiplication reversed when translating (reference
666 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17570).
668 2010-11-26 6.6.6-2 Glenn Randers-Pehrson <glennrp@image...>
669 * Revised the "c7x7b" and "c7x7w" ordered-dither maps to be complementary
672 2010-11-27 6.6.6-1 Cristy <quetzlzacatenango@image...>
673 * Add support for -evaluate-sequence median.
675 2010-11-26 6.6.6-0 Glenn Randers-Pehrson <glennrp@image...>
676 * Fixed two more cases where the PNG encoder lost transparency (reference
677 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17516).
679 2010-11-23 6.6.6-0 Cristy <quetzlzacatenango@image...>
680 * The policy.xml sets not-to-exceed resource values (e.g. policy memory limit
681 1GB, -limit 2GB exceeds policy maximum so memory limit is 1GB).
682 * Support NCC (normalized cross correlation) compare metric.
684 2010-11-21 6.6.5-10 Cristy <quetzlzacatenango@image...>
685 * Fix PNG coder compile error when HDRI is enabled.
687 2010-11-17 6.6.5-9 Glenn Randers-Pehrson <glennrp@image...>
688 * Many of the problems with the PNG encoder have been fixed (reference
689 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16490).
690 * The "-type Optimize" option is now deprecated. If present, it is treated
691 by the PNG encoder the same as if the type were undefined. Optimization
692 is now always performed. No other formats used the "type Optimize" option.
693 * Merged redundant code into LosslessReduceDepth() function in the PNG codec.
695 2010-11-14 6.6.5-9 Cristy <quetzlzacatenango@image...>
696 * The splice option no longer throws spurious "pixels are not authentic"
698 * Thread the -adaptive-resize option.
699 * Set XBM coder height to height not width.
701 2010-11-14 6.6.5-9 Nicolas Robidoux <nicolas.robidoux@gmai...>
702 * Lanczos2Sharp blur tweaked. New blur = 0.9549963639785485.
704 2010-11-13 6.6.5-9 Nicolas Robidoux <nicolas.robidoux@gmai...>
705 * LanczosSharp blur tweaked to minimize worst case deviation from "perfect
706 preservation of images which only vary horizontally (or vertically)" under
707 no-op. New blur = 0.9812505644269356.
709 2010-11-08 6.6.5-8 Nicolas Robidoux <nicolas.robidoux@gmai...>
710 * Missing logical operator in tiff.c.
712 2010-11-08 6.6.5-8 Cristy <quetzlzacatenango@image...>
713 * Only save TIFF image with 1-bit depth if there is no alpha channel.
714 * Abandon PSD composite if layer is available.
715 * %[fx:mean] is the mean of the default channels (all but opacity) (reference
716 http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=17432).
718 2010-10-29 6.6.5-6 Glenn Randers-Pehrson <glennrp@image...>
719 * Added 5x5, 6x6, and 7x7 ordered-dither level maps.
721 2010-10-30 6.6.5-5 Cristy <quetzlzacatenango@image...>
722 * Do not read configure files in the current directory for the "installed"
723 version of ImageMagick.
724 * Allow numeric characters in the XPM basename (reference
725 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17385).
727 2010-10-29 6.6.5-4 Glenn Randers-Pehrson <glennrp@image...>
728 * Revised PNG palette optimization
729 * Added some debug logging in coders/png.c.
731 2010-10-28 6.6.5-3 Nicolas Robidoux <nicolas.robidoux@gmai...>
732 * More precise blur values for Lanczos2Sharp and LanczosSharp.
733 * Added location of first Mitchell crossing (=8/7) to the filters data
736 2010-10-28 6.6.5-2 Anthony Thyssen <A.Thyssen@griffith...>
737 * Added Lanczos2D* filters now named Lanczos2*
738 * Reorganization of AcquireFilter() to make it work better
740 2010-10-25 6.6.5-1 Nicolas Robidoux <nicolas.robidoux@gmai...>
741 * Clearer EWA filters (LanczosSharp etc) comments.
743 2010-10-25 6.6.5-1 Anthony Thyssen <A.Thyssen@griffith...>
744 * Added LanczosSharp (3-lobe Lanczos with sharpening)
745 * Filter sharpening factors are also always applied regardless of usage.
747 2010-10-24 6.6.5-1 Nicolas Robidoux <nicolas.robidoux@gmai...>
748 * CubicBC filter formulas simplified by constant folding. In
749 particular, P1 coefficient (always zero) removed from coeff.
751 2010-10-22 6.6.5-1 Nicolas Robidoux <nicolas.robidoux@gmai...>
752 * Revert the Robidoux filter to a Keys cubic with C=(108 sqrt 2-29)/398
753 (as already specified in the documentation).
755 2010-10-14 6.6.5-1 Cristy <quetzlzacatenango@image...>
756 * Ignore PS bounding box offsets if -page is set.
757 * Use #pragma omp master for dumping single threaded debugging information
758 (single caused a fault).
759 * Add support for -evaluate exp.
761 2010-10-12 6.6.5-0 Anthony Thyssen <A.Thyssen@griffith...>
762 * Added "filter:sigma" expert setting defining the 'sigma' for the Gaussian
763 filter only. This is similar in action to 'blur' but only for Gaussians,
764 and does not modify the filters support, allowing you to set a very small
765 sigma, without the function 'missing' all pixels.
766 (This will allow future adjustment of Gaussians for variable blur mapping)
768 2010-10-10 6.6.5-0 Cristy <quetzlzacatenango@image...>
769 * Patch for DrawableRotation() and DrawableTranslation() (reference
770 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17246).
771 * The webp format requires the webpconv delegate program (experimental).
773 2010-10-05 6.6.5-0 Anthony Thyssen <A.Thyssen@griffith...>
774 * Replaced "Robidoux" with Cubic 'Keys' filter that is near equivalent to
775 the previous sharped "Lanczos2D" filter. (C=0.31089212245300069)
776 This also is very similer to a Mitchell filter but specifically designed
777 for EWA use and is the new default filter for Distorting Images.
778 * Original sharpened Lanczos2D filter now called "Lanczos2Dsharp"
780 2010-10-08 6.6.4-10 Jerry Gay <jerry.gay@gmail..>
781 * Autodetect file type support in Makefile.PL to prevent test failures
783 2010-10-05 6.6.4-10 Anthony Thyssen <A.Thyssen@griffith...>
784 * Added new filter 'Lanczos2D' a 2-lobe Lanczos as defined by
785 Andreas Gustafsson in his thesis "Interactive Image Warping" (page 24)
786 http://www.gson.org/thesis/warping-thesis.pdf
787 * Added filter "Robidoux" which is a slightly sharpened version of the
788 "Lanczos2D" filter (blur=0.958033808) specifically designed to be less
789 'blurry' for horizontal and vertical lines in no-op distortions.
791 2010-10-05 6.6.4-10 Cristy <quetzlzacatenango@image...>
792 * Add support for "pattern:vertical2" and "pattern:horizontal2".
793 * Add support for "pattern:vertical3" and "pattern:horizontal3".
794 * Properly handle PSD layers with negative offsets.
796 2010-10-03 6.6.4-9 Cristy <quetzlzacatenango@image...>
797 * Fix memory assertion with --enable-embeddable (reference
798 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17201).
799 * Don't permit access to pixels when pinging an image (reference
800 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17194).
802 2010-10-02 6.6.4-9 Anthony Thyssen <A.Thyssen@griffith...>
803 * Added sqrt(2) blurring default for Gaussian Filter if used as
804 a Cylindrical EWA filter. This resulted removing the last aliasing
805 issue that was present in tests for Gaussian EWA resampling. Of course
806 it is still a very blurry filter for default use in EWA.
807 * Adjusted Variable Mapping Blur Composition so user arguments actual
808 relate properly to the sigma of the blur for a maximum mapping value.
809 * Fix horizon anti-alising for output-scaled perspective distortions.
810 * 'Bessel' filter is now offically and more accuritally named 'Jinc'
811 however 'Bessel' while not visible as a filter option can still be used
812 as an internal alias for 'Jinc'.
814 2010-09-28 6.6.4-8 Nicolas Robidoux <nicolas.robidoux@gmai...>
815 * Chantal Racette double checked the bounding parallelogram computation
816 in resample.c (and I tightened the comments).
818 2010-09-28 6.6.4-8 Cristy <quetzlzacatenango@image...>
819 * Temporary files not always deleted (reference
820 http://www.imagemagick.org/discourse-server/viewtopic.php?f=2&t=15960).
822 2010-09-28 6.6.4-8 Anthony Thyssen <A.Thyssen@griffith...>
823 * Bug fix for -filter point distorts (occasional generating black pixels)
825 2010-09-27 6.6.4-8 Nicolas Robidoux <nicolas.robidoux@gmai...>
826 * Simplified the ClampUpAxes code, the use of its outputs, its comments,
827 and credited Craig DeForest for the "clamp singular values" idea.
828 * No reason to have "insane" precision Sinc in resize.c: Use
829 the 1.2e-12 max. abs. relative error version for Q64 as well as Q32.
831 2010-09-27 6.6.4-8 Anthony Thyssen <A.Thyssen@griffith...>
832 * Replace the blurry "High Quality EWA" technique with a 'Clamped EWA'
833 for Distort Resampling. This makes -distort a whole lot nicer
834 and allows for the use of better cylindrical filters.
836 2010-09-26 6.6.4-7 Anthony Thyssen <A.Thyssen@griffith...>
837 * Fix Point filter for ResizeImage() caused by support limiting the
838 Box weighting function.
840 2010-09-26 6.6.4-6 Cristy <quetzlzacatenango@image...>
841 * Don't allow resize filter weights to go to zero (reference
842 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17132).
844 2010-09-24 6.6.4-6 Nicolas Robidoux <nicolas.robidoux@gmai...>
845 * Now that MagickPIL is a MagickRealType, some casts are unneeded.
847 2010-09-21 6.6.4-6 Cristy <quetzlzacatenango@image...>
848 * Do not break words if caption size is absolute (reference
849 http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=17123).
850 * Don't define HAVE_THREADS for --without-threads configure script option.
852 2010-09-20 6.6.4-5 Nicolas Robidoux <nicolas.robidoux@gmai...>
853 * Modified "magick/resize.c" so that MagickPIL is a MagickRealType number.
854 Some computations were needlessly done in long double precision because
855 PIL forced an automatic upcast wherever it appeared. Changed its name to
856 MagickREALTYPEPI. <- This was later reverted back to MagickPIL.
857 * Modified "magick/resize.c" so that Bohman uses one trig call + one sqrt
858 call instead of two trig calls.
860 2010-09-20 6.6.4-5 Anthony Thyssen <A.Thyssen@griffith...>
861 * modified "magick/resample.c" to allow use of either EWA or HQEWA (default)
862 * Removed LanczosFast from supported filters (SincFast*SincFast is faster)
864 2010-09-19 6.6.4-5 Cristy <quetzlzacatenango@image...>
865 * If IPTC profile is not embedded in an 8bim resource, declare it IPTC
867 * Support %[version] and %[copyright].
868 * Improve performance of the pixel cache.
870 2010-09-18 6.6.4-4 Cristy <quetzlzacatenango@image...>
871 * Automatically set the quantum depth to 16 for HDRI.
873 2010-09-16 6.6.4-2 Cristy <quetzlzacatenango@image...>
874 * IPTC profile not always wrapped properly inside an 8BIM profile.
875 * TIFF tile geometry must be divisible by 16.
877 2010-09-15 6.6.4-2 Anthony Thyssen <A.Thyssen@griffith...>
878 * Rename of SincPolynomial to SincFast for easier user understanding
879 * Ditto for LanczosChebyshev to LanzcosFast
881 2010-09-14 6.6.4-2 Anthony Thyssen <A.Thyssen@griffith...>
882 * Switch default resize filters to using the faster SincPolynomial
883 filter by default internally. However 'Sinc' will still use the
884 Trigonometric function, and can be used to assign the trig version
885 of Sinc() to filters using the filter expert options.
886 * The default filter for 'distort' was found to be a very blurry inaccurate
887 filter function. It was removed and replaced with a correct Gaussian
888 filter (as used by resize)
889 * Added a switch so that "-interpolate filter" will force the use of
890 a cylindrical filter for ALL pixels in distorted images. That is you can
891 use that switch to use a cylindrical filter even for images that are
892 being enlarged by the distortion. However EWA is still currently using
893 a fixed 2.0 sampling radius. This switch complements the use of "-filter
894 point" which turns off EWA filters in favor of interpolation for all
895 pixels in a distorted image. BOTH switches should not be used together.
896 * A bug in the support radius of the EWA resampling function was found,
897 now that correctly defined resize filters are being used. Suddenly Normal
898 Gaussian distortions are not so blurry, and tests with distortions of
899 the 'Rings' image show extremely good and clear results, with only minimal
900 blurring. The filter 'blur' expert option can be used to adjust this
903 The above represents a major improvement forward in the quality of the
904 image distortion operator. But near-unity distortions (no scaling) are
907 2010-09-13 6.6.4-2 Cristy <quetzlzacatenango@image...>
908 * Don't negate the geometry offset for the -extent option.
910 2010-09-09 6.6.4-1 Cristy <quetzlzacatenango@image...>
911 * The RGBO format is now listed as a supported format.
913 2010-09-07 6.6.4-1 Anthony Thyssen <A.Thyssen@griffith...>
914 * Added the Nicolas Robidoux and Chantal Racette Lanczos resize filter
915 function as "LanczosChebyshev" as faster alternative to Lanczos.
916 * Re-code Nicolas Robidoux and Chantal Racette Polynomial Approximation of
917 the Sinc Trigonometric resize filter, as a proper filter to allow
918 direct comparision and speed testing of the filter.
919 * Expanded the "-set option:filter:verbose 1" output, so as to also include
920 the actual functions and other values that were used to create the filter.
922 2010-09-02 6.6.4-0 el_supremo <digipete@shaw...>
923 * Repair a few incorrect LocaleNCompare() calls (ttf.c, ps.c).
925 2010-08-31 6.6.4-0 Cristy <quetzlzacatenango@image...>
926 * Path no longer closed if join style is round (reference
927 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16943).
928 * Add case for BGRQuantum to GetQuantumExtent().
929 * Support no compression on PCX write.
931 2010-08-23 6.6.3-10 Cristy <quetzlzacatenango@image...>
932 * Fixed bug in the raw BGRA coders (reference
933 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16880).
934 * Fix off-by-one error in the PSD coders.
935 * Nicolas Robidoux with the assistance of Chantal Racette contribute an
936 approximation of the sinc function over the interval [-3,3].
937 * Eliminate a small memory leak in LevelizeImageChannel() (reference
938 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16951).
939 * Recognize -fx logtwo (reference
940 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16958).

943 * Throw exception if image size differs for the compare program but the
944 -subimage-search option is not specified.
946 2010-08-13 6.6.3-6 Cristy <quetzlzacatenango@image...>
947 * The AdobeRgb.tif TIFF image no longer faults under Windows (reference

949 * Add -subimage-search option to the compare utility.
951 2010-08-12 6.6.3-5 Cristy <quetzlzacatenango@image...>
952 * The -fx 2e+6/1e+5 argument no longer returns the wrong results (reference
953 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16833).
955 2010-08-10 6.6.3-5 Glenn Randers-Pehrson <glennrp@image...>
956 * Emit a warning if the PNG encoder can't satisfy the color type and
957 bit depth requested with a "-define" directive.
959 2010-08-07 6.6.3-4 Cristy <quetzlzacatenango@image...>
960 * The orient option sometimes improperly set "undefined" (reference
961 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16795).
962 * Only list orientation options for the -list orientation option (reference
963 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16801).
964 * Return proper standard deviation for combined channels (reference
965 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16786).
966 * Handle transparency properly for the PSD image format.

973 * Support -set density / units.
975 2010-07-31 6.6.3-2 Cristy <quetzlzacatenango@image...>
976 * Only use the first alpha channel in PSD image.
977 * Only use XPM complying colors for XPM images (e.g. green is rgb(0,255,0)).
979 2010-07-27 6.6.3-2 Glenn Randers-Pehrson <glennrp@image...>
980 * Eliminate useless message about assuming zero delay when writing
981 a single-frame MNG, and changed it from Error to Warning when
982 writing a multiple-frame MNG.
984 2010-07-25 6.6.3-1 Glenn Randers-Pehrson <glennrp@image...>
985 * Don't "ping" a PNG image if it is embedded in a MNG. Otherwise the
986 reader tries to read MNG chunks from the interior of the embedded PNG,
987 resulting in an erroneous "corrupted image" message.
989 2010-07-09 6.6.3-1 Cristy <quetzlzacatenango@image...>
990 * Fix memory leak in for corrupt BMP images (reference
991 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16600).
992 * Repair several issues when writing to stdout (reference
993 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16620).
994 * A GIF image with the .bgr extension is still a GIF (reference
995 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16662).
997 2010-07-07 6.6.3-1 Glenn Randers-Pehrson <glennrp@image...>
998 * The PNG decoder failed to handle the tRNS chunk properly for grayscale
999 images where the PNG bit_depth was not the same as the quantum depth,
1000 and the transparent color was not black.
1002 2010-07-01 6.6.3-0 Chris Madison <madisonblu@gmail...>
1003 * Pinging the DJVU image format no longer faults.
1004 * Check for time-limit-exceeded in only one thread.
1005 * Reading filenames from a file (e.g. @filenames) no longer includes the
1006 utility name (side effect of StringToArgv() method).
1008 2010-06-28 6.6.2-10 Cristy <quetzlzacatenango@image...>
1009 * Support the tiff:fill-order define.
1010 * Filters are case sensitive (e.g. reduce-Colors).
1011 * Restore mogrify's -path option.

1020 * Skip byte when DDS bitcount is 32 (reference
1021 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16487).
1022 * Montage now uses final background setting (e.g. montage -background none ...
1023 -background lightblue show:).
1024 * Do not annotate directory paths in ListFiles().
1025 * Reset the image matte for png:color-type=2.
1027 2010-06-17 6.6.2-7 Cristy <quetzlzacatenango@image...>
1028 * Support new label:pointsize property.
1029 * Miscellany->Slide Show, in the display program, now cycles through the
1031 * Recognize certain hex color values (e.g. #b9e1cc00) for the -fx argument.
1032 * Reduce memory requirements when dithering on the iPhone.
1033 * Command line operators no longer affected by settings that appear after
1034 them (e.g. -splice 10x0+0+0 -gravity center).
1035 * Compute the proper DPX user data field size.
1037 2010-06-15 6.6.2-6 Cristy <quetzlzacatenango@image...>
1038 * Fix some nits to keep the clang compiler happy.
1040 2010-06-14 6.6.2-5 Anthony Thyssen <A.Thyssen@griffith...>
1041 * Fix transprancy handling for Morphology Convolve
1042 * Adjustments of Hit And Miss and Edge Detection kernel definitions
1043 * Added 'ThinDiagonals' Thinning Kernel + two sub-types
1044 * Handling for Convolution of 1-D vertical kernels.
1045 However this was removed (using #if-#endif) as I found it slower in tests!
1047 2010-06-12 6.6.2-5 Cristy <quetzlzacatenango@image...>
1048 * mogrify -format properly handles compressed image filename (e.g.
1049 -format jpg logo.png.bz2).
1050 * Respect +dither option when saving to the GIF image format.
1052 2010-06-08 6.6.2-4 Cristy <quetzlzacatenango@image...>
1053 * End of string sentinal is \n not \r.
1055 2010-06-06 6.6.2-3 Glenn Randers-Pehrson <glennrp@image...>
1056 * Don't decode pixels in coders/png.c when image->ping is set.
1058 2010-06-06 6.6.2-3 Cristy <quetzlzacatenango@image...>
1059 * Reset image filename when reading inline images.
1060 * Don't clamp floating point values for HDRI-enabled ImageMagick.
1062 2010-05-25 6.6.2-2 Anthony Thyssen <A.Thyssen@griffith...>
1063 * Replaced '^' morphology kernel rotation with two variants '>' and '<'
1064 * 'Skeleton' variant to thin down images as symmetrically as possible.
1065 * Spelling correction: Manhatten -> Manhattan
1067 2010-06-01 6.6.2-2 Glenn Randers-Pehrson <glennrp@image...>
1068 * Properly scale color components of the PNG bKGD chunk.
1069 * Prevent MNG divide by zero in calculation of frame_timeout. Set
1070 both frame_delay and frame_timeout to infinite when ticks_per_second
1071 is zero, as required by the MNG spec.
1073 2010-05-31 6.6.2-2 Cristy <quetzlzacatenango@image...>
1074 * Add x:silent option to prevent beeps when reading the X image format.
1075 * Recognize TTF for GetMagicInfo().
1076 * Ensure the +set option deletes the image artifact.
1078 2010-05-28 6.6.2-1 Glenn Randers-Pehrson <glennrp@image...>
1079 * Prevent coders/png.c from attempting to write an empty tRNS chunk.
1081 2010-05-25 6.6.2-1 Anthony Thyssen <A.Thyssen@griffith...>
1082 * Fix for Square Array Rotates (off center origin rotate)
1083 * Added HitAndMiss kernel Ridges2 to find 2 pixel thick ridges
1084 * Added FreiChen:0,{angle} FreiChen:{angle} and FreiChen:-1 variations
1085 to complete this kernels definition
1087 2010-05-24 6.6.2-1 Cristy <quetzlzacatenango@image...>
1088 * Respect density when rendering SVG images.
1089 * Set AVI handler to the MPEG coder.

1093 * Use 64-bit types when compiling with the 64-bit Visual C++ compiler under
1095 * Prevent MNG divide by zero in calculation of frame_delay (reference
1096 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16320).
1098 2010-05-23 6.6.2-0 Anthony Thyssen <A.Thyssen@griffith...>
1099 * Third Re-write of MorphologyApply() to better handle compound methods.
1100 * Implemented -set option:morphology:compose for merging results of
1101 multiple kernels. "None" means re-iterate results with next kernel.
1102 While "Undefined" means to use the internal default for a method.
1103 Thinning, Thickening, HitAndMiss, Convolve, Correlate defaults to "None"
1104 while HitAndMiss defaults to "Lighten" (union of all kernel results).
1105 Other morphology methods defaults still to be decided.
1106 * Added HitAndMiss Kernel: Ridges (find ridges and pixel width lines)
1107 * Rotation Expansion of single kernels '^' and '@' flags in arguments
1108 EG: -set option:showkernel 1 -morphology Convolve 'Blur:0x2^'
1109 * ExpandKernelInfo() (rotation expand) now groks symmetrical kernels.
1110 So the above will only produce a list of 2 kernels, not 4 kernels
1112 2010-05-18 6.6.2-0 Anthony Thyssen <A.Thyssen@griffith...>
1113 * Separation of internal function MorphologyApply() from
1114 MorphologyImageChannel() to calls to convolve without user settings.
1115 * Rewrite of MorphologyApply() to output better 'verbose' messages
1116 * Better handling of Gaussian tyle filters (bug fixes)
1117 * Bug fix and optimization of kernel size calculations in "gem.c"
1118 * Allow '^' or '@' flags in 'user defined' kernel size arguments to
1119 expand kernel into a rotated list.
1120 EG: -set option:showkernel 1 -morphology Thinning '3@: 0,1,0 0,1,0 0,0,0'
1121 * Allow a scaled unity kernel to be added to kernel (EdgeDet->Sharpen)
1122 EG: -set option:convolve:scale [kernel_scale][^!],[unity_scale][%]
1123 * Addition of "Laplacian of Gaussian" (LOG), also known as Mexican Hat
1124 EG: -morphology convolve LOG:0x1
1125 * Added FreiChen, Kirsch Convolution kernels
1126 * Added Descrete 'Laplacian of Gaussian' kernels (Laplacian type 15 and 19)
1127 * Added Edges HitAndMiss Kernel
1129 2010-05-17 6.6.2-0 Cristy <quetzlzacatenango@image...>
1130 * PSD images require a proper layer to support an alpha channel.
1131 * Enable PFM endian support.
1132 * Add context to -border for montage. Inside the parenthesis it adds a border
1133 to the image otherwise it sets the border for the layout manager.
1134 * 24-bit BMP images are not colormapped even if header colors != 0.
1135 * Set DPX user data like this: -set profile dpx:userdata.txt.
1136 * Make sure Lab => RGB => Lab survives the round trip.
1138 2010-05-15 6.6.1-10 Cristy <quetzlzacatenango@image...>
1139 * Use ScaleCharToQuantum() in coders/src.c (reference
1140 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16229).
1141 * Don't clamp HDRI EXR pixels.
1143 2010-05-14 6.6.1-9 Cristy <quetzlzacatenango@image...>
1144 * Increase the estimated # points for the path drawing primitive.
1145 * Remove any prior resolution block from PSD before writing the new block.
1147 2010-05-14 6.6.1-9 Anthony Thyssen <A.Thyssen@griffith...>
1148 * Addition of more Morphological/Convolution Kernels.
1149 DOG (Difference of Gaussians) and DOB (Difference of Blurs),
1150 EG: -morphology convolve DOG:0x1,3
1151 -morphology convolve DOB:0x1,3,90
1152 * Added Prewitt, Roberts, Compass Convolution Kernels
1153 * Ring Symbol Kernel (subtraction of Disk from a Disk)
1155 2010-05-13 6.6.1-9 Cristy <quetzlzacatenango@image...>
1156 * The pixel buffer was underallocated for some image formats when streaming.
1158 2010-05-12 6.6.1-8 Anthony Thyssen <A.Thyssen@griffith...>
1159 * Implementation of Pattern Matching Morphology methods
1160 HitAndMiss, Thicken, Thinning
1161 * Reporting of Kernel Strings that fail to parse (though not why)
1162 * Parsing of Multiple Kernel Strings, generating a list of kernels
1163 * Union of results from Multiple Kernels for HitAndMiss method
1164 * Interated Multiple Kernels for all other morphology methods
1165 * Added many new kernels for HitAndMiss and Convolution
1166 Sobel, Laplacian, Cross, Peaks, Corners, LineEnds, LineJunctions,
1167 ConvexHull (for Thicken), Skeleton (for Thinning)
1169 2010-05-08 6.6.1-8 Glenn Randers-Pehrson <glennrp@image...>
1170 * Use proper background.index when writing indexed PNG, if the background
1171 color is in the palette.
1173 2010-05-08 6.6.1-7 Cristy <quetzlzacatenango@image...>
1174 * Fix improper 'invalid colormap index' PNG bug.
1175 * Fix PerlMagick compile exception.
1177 2010-05-07 6.6.1-6 Anthony Thyssen <A.Thyssen@griffith...>
1178 * Added % and ! modification flags to morphology distance kernel
1179 scaling factor, for easier usage.
1180 * Bug fix for compose math channel handling and morphology diff usage
1182 2010-05-06 6.6.1-6 Cristy <quetzlzacatenango@image...>
1183 * Do not claim gray colorspace if gray image includes a non-gray pixel.
1184 * Initialize BMP alpha channel to opaque for RGB images.
1185 * Fixed under allocation for round rectangles.
1186 * The -list option returns a 0 status as expected.
1188 2010-05-06 6.6.1-6 Anthony Thyssen <A.Thyssen@griffith...>
1189 * Made use of new no-'sync' channel enabled mathematical compose methods
1190 for the difference morphology methods. These should now work correctly
1191 for specific channels, and more importantly for alpha shaped morphology.
1193 2010-05-05 6.6.1-6 Glenn Randers-Pehrson <glennrp@image...>
1194 * Fixed bugs with losing the opacity channel while writing some PNG images.
1195 (bug reported by Anthony T.)
1197 2010-05-05 6.6.1-6 Glenn Randers-Pehrson <glennrp@image...>
1198 * Simplified and corrected rowbytes calculation in coders/png.c and
1201 2010-05-05 6.6.1-6 Anthony Thyssen <A.Thyssen@griffith...>
1202 * Rename of "Add" and "Subtract" compositions to "ModulusAdd" and
1203 "ModulusSubtract" for more clarity of there functions. Old names
1204 will continue to work as expected.
1205 * Fix "Minus", "ModulusAdd", and "ModulusSubtract" to follow
1206 normal SVG 'Over' blending specifications, (see next for override)
1207 Note that this does NOT include the "Plus" composition method which has
1208 SVG definition for it to use a 'Plus' blending rather than 'Over' blending.
1210 * By default mathematical compositions work as per SVG definition. That is
1211 the results are synchronized with 'Over' alpha-blending (except "Plus"
1212 which uses 'plus' alpha-blending).
1214 By removing the default 'sync' flag from the -channel setting however
1215 Break this inter-channel synchronization and do the mathematical operations
1216 only on the individual channels as specified by the -channel setting.
1217 That is do 'channel' math rather than 'SVG' composition.
1219 With this change you can then use mathematical composition methods on
1220 individual channels or even with the alpha channel of images.

1391 * Ensuring original kernels passed to morphology are cloned before being
1392 modified for use by specific methods (EG: convolve scale/normalize)
1394 2010-02-03 6.5.9-2 Cristy <quetzlzacatenango@image...>

1401 * added use of -precision in 'showkernel' output of -morphology
1402 * correct use of a 'reflected kernel' for 'Convolve' 'Dilate' and
1403 'Distance' Morphology primitives. This does not have a performance hit,
1404 though is only truely applicable when the kernel is asymmetric. Note that
1405 'Erode' does not use a 'reflected' kernel, so that 'Open' and 'Close'
1406 operations work properly. This 'reflected usage is defined by online
1407 morphology lecture notes (Google for "EECE Binary Morphology")
1408 * Added convolve kernel scaling setting "-set option:convolve:scale N"
1409 If undefined morphology convolve does not do any scaling or normalization
1410 of the convolution kernel. A value of 0.0 causes normalization for both

1434 2010-01-04 6.5.9-0 Anthony Thyssen <A.Thyssen@griffith...>
1435 * Added Kernel Generator to generate kernels from user strings, which
1436 allows the generation in many built in kernels for both Convolution
1437 and other Morphological methods. New Kernels currently include..
1438 Convolution: Gaussian, Blur, Comet
1439 Morphological: Rectangle, Square, Diamond, Disk, Plus
1440 Distance: Chebyshev, Manhatten, Knight, Euclidean
1441 And both old and new (rectangular) user defined kernel specifications
1442 including the use of 'nan' to represent elements which are not part
1443 of the kernel definition. List built-in kernel types use "-list kernel"
1444 * Added -morphology {method}[:{iteration}] {kernel_string}
1445 Initial methods includes no only the basic morphology methods: Dilate,
1446 Erode, Open, Close; and a pixel color preserving 'Intensity' version, but
1447 also the special methods: Convolve, and Distance. Of course the
1448 appropriate kernel should be provided for each specific method.
1450 2010-01-01 6.5.9-0 Cristy <quetzlzacatenango@image...>
1451 * Add OpenCL-enabled filter (e.g. convert image.png -process
1452 "convolve '-1, -1, -1, -1, 9, -1, -1, -1, -1'" image.jpg).
1453 * Added StringTo...() processing functions
1455 2009-12-27 6.5.8-9 Anthony Thyssen <A.Thyssen@griffith...>
1456 * Added MxN tile cropping with overlapping and space handling.

1653 enabled by default. This replaces the current 'channels not modified'
1654 type handling thought IM.
1655 * Modified -channel parsing to continue looking for words, after handling
1656 any shorthand channel options. For example: -channel RGB,sync

1690 * Replace color blending in DrawGradientImage() to use Composite Blend.
1691 this makes Gradients handle transparency correctly!
1693 2009-07-28 6.5.4-7 Cristy <quetzlzacatenango@image...>
1694 * The -thumbnail option no longer removes color profiles (reference
1695 http://www.imagemagick.org/discourse-server/viewtopic.php?f=2&t=14312).
1696 * Do not scale real / imaginary FFT / IFT.
1697 * Check for localtime() NULL return.
1698 * import --help requires an X server (reference
1699 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=14323).
1700 * Fails to load MS Windows icons with compressed PNG elements (reference
1701 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=14324).
1703 2009-07-25 6.5.4-6 Cristy <quetzlzacatenango@image...>
1704 * Support the new JPEG version 7 delegate library.
1706 2009-07-24 6.5.4-6 Alexander E. Patrakov <patrakov@gmail...>

1716 * Don't use JPEG's color reduction algorithm for less than 8 colors.
1718 2009-07-13 6.5.4-3 Anthony Thyssen <A.Thyssen@griffith...>
1719 * Final testing and bug fixes for all mathematical compose methods
1720 Including non-overlapping regions bugs found in in operators Divide,
1721 ColorDodge, VividLight. And the handling of transparency to follow
1722 standard 'Over' Blending in Divide. Only math methods not looked at are
1723 the addition methods Plus, Add, Minus, and Subtract, which do not follow
1724 normal 'Over' alpha blending behaviour, for the purposes of mask handling.
1726 2009-07-12 6.5.4-3 Anthony Thyssen <A.Thyssen@griffith...>
1727 * Addition of user definable 'Mathematics' compose method
1728 -compose Mathematics -set option:compose:args A,B,C,D -composite
1729 Will implement the formula f(Sc,Dc) = A*Sc*Dc + B*Sc + C*Dc + D

1741 Added extra composition modes:
1742 VividLight, PinLight, LinearBurn, LinearDodge
1743 NOTE: 'LinearBurn' the same as 'Plus' but with the normal 'Over' blending.
1745 2009-07-10 6.5.4-3 Anthony Thyssen <A.Thyssen@griffith...>
1746 * Re-coding of Composite methods HardLight, SoftLight, Overlay, LinearLight,
1747 ColorBurn, ColorDodge, Multiply, Screen to make it more readable, easier
1748 to debug, and directly comparable to SVG specifications.
1749 * Specifications changed for SoftLight, ColorBurn, ColorDodge
1750 Though only SoftLight changed to significantly.
1751 * However implementation errors were found for ColorBurn, LinearLight

1775 2009-06-23 6.5.4-0 Anthony Thyssen <A.Thyssen@griffith...>
1776 * Automatic determination of B from C and C from B for a 'Keys Filter'
1777 when using the B,C Cubic Filter Expert options was broken.
1778 See http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=14037
1780 2009-06-19 6.5.4-0 Anthony Thyssen <A.Thyssen@griffith...>

1795 * Improve FITS keyword parser.
1797 2009-06-14 6.5.3-7 Anthony Thyssen <A.Thyssen@griffith...>
1798 * Cleanup of compose 'displace' of old useless code that is not used.
1799 * Implement a compose 'distort' mapping method,
1800 This is basically exactly like 'displace' but relative to a fixed point
1801 which may be user supplied as +X+Y
1802 * Default scaling to width/2 and height/2 of overlay (100% scale)
1803 with a distortion 'center' to the middle of the overlay image
1804 * If a '%' flag given scale displacement relative to image size
1805 * If a '!' flag given make scale and center relative to 'background' image
1806 instead of the overlay map.
1807 * If no 'height' scale given, use the X scale.
1809 2009-06-13 6.5.3-6 Anthony Thyssen <A.Thyssen@griffith...>
1810 * Fixed bug for compose methods, Hue, Saturate, Luminize

1817 2009-06-11 6.5.3-5 Anthony Thyssen <A.Thyssen@griffith...>
1818 * Fixed "convert" to merge the third 'mask' image into the 'source' image
1819 for correct handling of 2 dimensional -compose "displace".
1820 * Fixed PerlMagick Composite() for the same thing.
1821 * Modified compose "Displace" so displacement image's alpha channel can be
1822 used to mask the transparency of the overlay area.
1824 2009-06-07 6.5.3-4 Cristy <quetzlzacatenango@image...>
1825 * Added the HALD image Color LUT, and a no-op HALD: image generator.
1826 See Introduction at http://www.quelsolaar.com/technology/clut.html
1828 2009-06-07 6.5.3-4 Anthony Thyssen <A.Thyssen@griffith...>
1829 * Changed CompositeImageChannel() so that extra compose arguments are
1830 now passed in the ImageArtifact "compose:args". This can be assigned to
1831 images using -set "option:compose:args" 'args' where args are defined
1832 using 'geometry' style or 'comma separated numbers'.
1833 * Declared the special flag needed for Composite Tiling as the ImageArtifact
1834 "compose:outside-overlay".
1835 * Documentation update for CompositeImageChannel() in Core Library to
1836 reflect these changes.
1837 * Documentation update for DistortImage() in Core Library with the extra
1838 ImageArtifact controls it can use.

1887 2009-05-14 6.5.2-5 Glenn Randers-Pehrson <glennrp@image...>
1888 * Updated help output and command-line options documentation to bring
1889 the -alpha options up to date with what's actually in the code.
1891 2009-05-13 6.5.2-5 Glenn Randers-Pehrson <glennrp@image...>
1892 * Change "depreciated" to "deprecated" in several files.

1900 2009-05-08 6.5.2-4 Cristy <quetzlzacatenango@image...>
1901 * Combined layer of transparent PSD image was not being read properly.
1903 2009-05-06 6.5.2-3 Glenn Randers-Pehrson <glennrp@image...>
1904 * Progress on "-define png:bit-depth=value" and "-define png:color-type=value"
1905 It is now able to write an opaque black-and-white image in any of the 15
1906 valid combinations of PNG color-type and bit-depth.
1907 * Fixed a regression with writing sub-8-bit grayscale PNGs.
1909 2009-05-06 6.5.2-2 Chris Madison <madisonblu@gmail...>
1910 * Create 8-bit TIFF images if -depth is set to 8 and HDRI-enable ImageMagick.
1912 2009-05-04 6.5.2-1 Chris Madison <madisonblu@gmail...>
1913 * Accept file lists on the command line (e.g. echo "rose: rose.png" |
1915 * Duplicate line in tiff.c breaking read of zip compressed tif (reference
1916 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=13688).
1917 * Support policies to permit or deny any coder, delegate, filter, or file
1918 path (see policy.xml).
1920 2009-05-02 6.5.2-0 Chris Madison <madisonblu@gmail...>
1921 * The mogrify -crop option returns multiple images if an x/y offset is not
1922 specified (e.g. -crop 100x100).
1923 * Generate a proper file path for -path @filelist.txt (reference
1924 http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=13671).
1926 2009-05-01 6.5.2-0 Glenn Randers-Pehrson <glennrp@image...>
1927 * Accept "-define png:bit-depth=value" and "-define png:color-type=value"
1928 options. This is work-in-progress with the objective of being able to
1929 precisely specify the type of PNG file to be written. The previously-used
1930 internal attribute "png:bit-depth" that was used to communicate between
1931 the PNG writer and the JNG writer is changed to "png:bit-depth-written".
1932 This feature needs testing. It is important to note that this feature
1933 cannot be used to force the PNG to use a bit-depth or color-type that
1934 does not losslessly represent the image. You can, however, cause
1935 the writer to use a larger depth or to use the RGB colorspace when
1936 grayscale or indexed would have been sufficent.
1938 2009-05-01 6.5.1-10 Anthony Thyssen <A.Thyssen@griffith...>
1939 * Fixed the Rmin usage in Depolar and Polar distortions
1940 * The 6th argument (Ato) for Polar/Depolar is now optional and defaults
1941 to Afrom + 360 degrees (or a fill circle from the given start angle)
1943 2009-04-30 6.5.1-10 Cristy <quetzlzacatenango@image...>
1944 * Do not return a black image for -channel RGBA -gaussian (reference
1945 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=13669).
1947 2009-04-28 6.5.1-9 Cristy <quetzlzacatenango@image...>

1956 http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=13609).
1957 * Normalize similarity based on reconstruction not the original (reference
1958 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=13626).
1959 * Support multiple JPEG images encapsulated within DICOM.
1961 2009-04-23 6.5.1-6 Cristy <quetzlzacatenango@image...>
1962 * Msys does not understand NAME_MAX.

1967 2009-04-21 6.5.1-4 Glenn Randers-Pehrson <glennrp@image...>
1968 * Check error return from CompressColormapTransFirst() in coders/png.c
1970 2009-04-21 6.5.1-4 Glenn Randers-Pehrson <glennrp@image...>
1971 * Refrain from modifying image struct members (color, depth, matte)
1972 while writing PNG datastreams.
1974 2009-04-21 6.5.1-4 Glenn Randers-Pehrson <glennrp@image...>
1975 * Sometimes the PNG8: format would produce 1-, 2-, or 4-bit PNG datastreams.
1976 Now it always produces 8-bit datastreams as users probably expect.
1978 2009-04-21 6.5.1-4 Glenn Randers-Pehrson <glennrp@image...>
1979 * Suppressed "shadowed declaration" warnings in coders/jpeg.c and
1980 coders/png.c that are triggered by "-Wshadow" gcc compiler flag.

1994 * Image not properly placed when displaying to the X server root (reference
1995 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=13532).
1996 * fmax() is not support on some platforms (reference
1997 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=13533).
1999 2009-04-11 6.5.1-2 Anthony Thyssen <A.Thyssen@griffith...>
2000 * Rename existing "Bilinear" distortion as "BilinearReverse"
2001 * Added forward mapped bilinear distort as "BilinearForward"
2002 * The "Bilinear" distort is temporarily obsoleted but will eventually
2003 be added as a "BilinearReverse" and "BilinearForward" combination
2004 mapping though a unit square.
2005 * Sparse Gradient internally uses "BilinearReverse" for its "Bilinear"
2006 gradient function as that method is the direct use of such equations.

2652 Function maps black and white values to the given level values.
2653 Rather than mapping the given level values to black and white.
2654 Bacically a 'reverse-level' function, with different input args.
2655 * Set +level or a '!' flag in -level or LevelImage() to call
2656 the new 'reverse-level' function LevelizeImageChannels().
2657 * More work on IsMagickColorSimular() to fix relationship between
2658 transparent-black and opaque-black, which was matched as 'simular'.
2659 Also attempts to fix 'K' channel handling for CMYK colorspace.
2660 More work on this to come.
2662 2008-06-25 6.4.1-9 Cristy <quetzlzacatenango@image...>

2778 * Instead of masking the PNG tRNS values when reducing from 16-bit,
2779 set image->matte to MagickFalse and emit a warning. This will produce
2780 behavior similar to that of libpng-1.2.27 (and libpng-1.2.19 and earlier).

2796 * Revised png.c to avoid saving unknown chunk types that will never
2797 be used later. This prevents the vulnerability described in
2798 CVE-2008-1382, with respect to all unknown chunks except vpAg.
2799 To handle an invalid, zero-length vpAg chunk properly will require
2800 libpng-1.2.27 or later.

3005 2007-11-03 6.3.6-7 Chris Madison <madisonblu@hotma...>
3006 * MAGICK_ERX_SRCS should be MAGICK_EXR_SRCS in coders/Makefile.am.
3008 2007-11-02 6.3.6-6 Cristy <quetzlzacatenango@image...>
3009 * Upgrade to FPX version libfpx-1.2.0.14 (reference
3010 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=10041).
3011 * Modules are searched first in the directories specified by the environment
3012 variables, and then -- if the desired module is not found -- in the
3013 compiled-in path. (reference
3014 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=10039).

3029 * Further expansion and handling of filters with expert options.
3030 -filter selects from a table of standard filter settings, while
3031 expert options allow complete selection of filter, windowing, support
3032 and blurring options. Includes automatic switch from Sinc to Bessel
3033 for operators using 2-dimensional cylindrical filter, rather than
3034 two pass 1-dimensional orthogonal filters.
3036 2007-10-14 6.3.6-3 Cristy <quetzlzacatenango@image...>
3037 * Obsolete -support (set filter blur factor)
3038 * Expansion to add -set/define filter options
3040 2007-10-12 6.3.6-2 Anthony <anthony@griffith...>
3041 * Least Squares coordinate handling added for -distort methods Affine,
3042 Perspective, Bilinear. This allows for more than the minimal number of
3043 coordinates to be used to 'fit' a distortion function to an image.
3044 This addition will allow the use of image registration to generate
3045 panarama overviews and better geographical coordinate correction.
3046 * Cosolidated the simular methods FlattenImage() and MosaicImage()
3047 into a new layers function MergeImageLayers() method, adding 'flatten'
3048 and 'mosaic' layer methods.
3049 * Addition of another simular layers method 'merge' which 'unlocks' the
3050 normal flatten/mosaic layer merger from the origin, The resulting image
3051 will have a virtual canvas of minimal size with an offset. Also images
3052 with negative offsets will not be clipped by the 'merge' form of the
3053 command. This was created for better layering of distorted images, such
3054 as panarama overlays.
3055 * Bug fix in handling transparency for EWA resampling.
3056 * Access to Resize Filter Functions from resize.c (for resample.c)
3057 with possible future filter sources... Acquire/Destory/Call ResizeFilter()

3060 2007-10-05 6.3.6-2 Cristy <quetzlzacatenango@image...>
3061 * The box filter no longer produces a black grid when resizing an image
3063 * Respect cropbox for PDF with a subimage specification (e.g.
3065 * Detect proper PDF bounding box when offsets are negative.
3067 2007-10-02 6.3.6-1 Cristy <quetzlzacatenango@image...>
3068 * Speed up the Fx interpreter.
3069 * Use ULL not ui64 for MinGW 64-bit constants.
3070 * Call SyncCacheView() instead of SyncImagePixels() in WaveImage().
3071 * Close all references to a pixel cache on disk before removing the temporary
3072 file as required under Windows.
3074 2007-09-29 6.3.6-0 Anthony <anthony@griffith...>
3075 * Added Scaling 'derivitives' to -distort Arc, so image arcing is now
3076 sharp and clear as you approach the center of the distort.
3077 * Added " -set option:distort:viewport 'geometry' " special option
3078 that can be used to override the output image size and offset.
3079 * Fixed experimental use of -filter and -support in Resampling (more later).
3080 * Changed order for coordinate arguments in -distort (for later leastsq
3081 multiple coordinate distortion function fitting)
3083 2007-09-22 6.3.6-0 Cristy <quetzlzacatenango@image...>
3084 * Check the API version and quantum depth before loading a coder module or
3085 image filter (reference
3086 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=9780).
3087 * Add exception to the image filter signature.
3088 * Get the execution path under Mac OS X.
3089 * TIFFTAG_STRIPBYTECOUNTS requires a uint32 pointer (magick/compress.c).
3090 * Fixed memory leak in CloneString() (reference
3091 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=9763).
3092 * Set S_IRUSR | S_IWUSR | S_IRGRP mode when writing a file in
3095 2007-09-18 6.3.5-9 Anthony <anthony@griffith...>
3096 * Bug fix for +distort in Perspective, also effected PerspectiveProjection
3098 2007-09-17 6.3.5-10 Cristy <quetzlzacatenango@image...>
3099 * Replace all InterpolatePixelColor() calls to use the ResamplePixelColor()
3101 * Map the display program pan icon window for each oversized image.
3102 * The ufraw delegate does not like quotes around the output filename.
3103 * Adjust the sensitivity of a few PerlMagick tests to pass the validation on
3104 a 64-bit FreeBSD system.
3105 * The -level option now works properly for colormapped images.
3106 * Allow Extrapolated blending of images using -blend
3107 http://netpbm.sourceforge.net/doc/extendedopacity.html
3109 2007-09-12 6.3.5-9 Anthony <anthony@griffith...>
3110 * Major Addition, Area Resampling Functions, (scaled interpolation)
3111 for pixel lookup in Distortion functions. This improves the look in
3112 areas of minification enormousally, especially in situations of infinite
3113 tiling and horizon views. All virtual pixel methods have been handled
3114 to minimise computation time involved with area resampling. To use the
3115 new function distortions need to be able to determine scaling vectors
3116 (distortion function derivitives) for correct working. All
3117 -distort methods, except Arc, uses scaled area resampling.
3118 * Improvements to perspective distort method, to include the correct
3119 differentation between the 'ground' on which the image lies, and the
3120 'sky', the color of which can be set using the -mattecolor setting
3121 (as the distortion invalid pixel color). Background color is retains
3122 for surrounding ground areas. The horizon is also correct anti-aliased
3123 and transparent colors are also allowed, allowing you to add backdrops
3124 of gradients and patterns.

3187 2007-07-25 6.3.5-4 Cristy <quetzlzacatenango@image...>
3188 * Remove extranous break statement so -type option properly sets the
3189 image_info->type member (reference
3190 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=9261).
3192 2007-07-21 6.3.5-4 Anthony <anthony@griffith...>
