3 * Fix FX default for interpolation to Bilinear
5 2011-04-30 6.6.9-7 Cristy <quetzlzacatenango@image...>
8 2011-04-27 6.6.9-7 Cristy <quetzlzacatenango@image...>
9 * Fix pixel interpolation for -draw image over (reference
10 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18612).
12 2011-04-26 6.6.9-7 Glenn Randers-Pehrson <glennrp@image...>
13 * Write the proper bKGD chunk value in grayscale PNG images (reference
14 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18624).
16 2011-04-25 6.6.9-7 Anthony Thyssen <A.Thyssen@griffith...>
17 * Added Inverse method for Sparse Color Interpolation
19 2011-04-24 6.6.9-6 Cristy <quetzlzacatenango@image...>
20 * New version 6.6.9-6.
22 2011-04-21 6.6.9-6 Anthony Thyssen <A.Thyssen@griffith...>
23 * Make filter:blur define a multiplicative adjustment of filter settings
24 rather than a complete override of those settings.
25 * Add Flags to CommandOptions parse table, removing the need for
26 ImageListOptions parsing table. This is the start of development to
27 produce a "convert" replacement that can read options from both command
28 line and from files or pipelines, in "Do it Immediately" handling.
29 * Crop Bug Fix. Prevent infinite loop with "+repage -crop 0x40"
31 2011-04-18 6.6.9-6 Glenn Randers-Pehrson <glennrp@image...>
32 * Added "date" to the things that can appear on the -define PNG:exclude-chunk
33 list. This excludes the IM-generated Date:modify and Date:create
34 properties from PNG output text chunks without excluding the rest of the
36 * Added "-define PNG:preserve-colormap" option (reference
37 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18564).
38 * Simplified LosslessReduceDepthOK() function in coders/png.c
40 2011-04-18 6.6.9-6 Cristy <quetzlzacatenango@image...>
41 * Add support for writing RGB FITS images as separate planes.
43 2011-04-16 6.6.9-6 Cristy <quetzlzacatenango@image...>
44 * Support the HDR 32-bit_rle_xyze format.
45 * Fixed infinite loop for TARGA images with a V2 develop area.
46 * Add signal handler for SIGBUS.
48 2011-04-15 6.6.9-5 Cristy <quetzlzacatenango@image...>
49 * New version 6.6.9-5.
51 2011-04-15 6.6.9-5 Glenn Randers-Pehrson <glennrp@image...>
52 * Added "#define PNG_PTR_NORETURN" because this macro does not work
53 on all platforms with libpng15, with failure to load png_longjmp() (ref
54 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18518).
56 2011-04-14 6.6.9-5 Anthony Thyssen <A.Thyssen@griffith...>
57 * Layers Composition Bug Fix, animations attributes of first image not
58 transferred in a single destination, multi-source image composition.
60 2011-04-09 6.6.9-5 Anthony Thyssen <A.Thyssen@griffith...>
61 * Add a special 'Voronoi' Morphology Distance method that will fill in holes
62 using the nearest non-transparent edge pixel. It is experimental, and
63 hidden from normal morphology usage, as it may be interfaced with a
64 future hole-filling color 'Diffusion' method.
66 2011-04-08 6.6.9-5 Cristy <quetzlzacatenango@image...>
67 * MIFF keywords sometimes includes spaces.
69 2011-04-07 6.6.9-5 Anthony Thyssen <A.Thyssen@griffith...>
70 * Major BUG FIX - wrong sign breaks most morphology methods in IM v6.6.9-4
71 * Fixed -region handling of transparency. Original images without
72 transparency will use 'Over' while images with transparency will
73 preserve transparency using 'Copy'. Before this only 'Over' was used
74 due to the testing of the wrong image.
75 * Added Compose methods DarkenIntensity and LightenIntensity
77 2011-04-06 6.6.9-4 Cristy <quetzlzacatenango@image...>
78 * New version 6.6.9-4.
80 2011-04-03 6.6.9-4 Anthony Thyssen <A.Thyssen@griffith...>
81 * Add Octagon shape and Octagonal distance kernels for Morphology
82 * Fix minor Morphology kernel compose bug (cleanup after Src/Dst swap)
83 * Fix segmentation fault after error in a morphology 'named' kernel
84 * Added a range of kernels used for specialised thinning purposes
85 as defined in a research paper by Dan S. Bloomberg.
86 * Added Dan Bloomberg best thinning skeletion, "Skeleton:3"
87 * Removed origin pixel from many Hit-and-Miss kernels allowing kernels
88 to not only be used for thinning, but also thickening.
89 * Renamed "ThinDiagonals" kernel to just "Diagonals"
90 * Distance uses a fast two pass algorithm, and no longer needs 'iteration'
92 2011-04-02 6.6.9-4 Glenn Randers-Pehrson <glennrp@image...>
93 * Make the PNG encoder use depth==8 when incoming image->depth < 8
94 (the encoder later reduces the depth if it can), to avoid writing
96 * Remove any bogus colormap received by the PNG encoder with an image
97 that is not PseudoClass (reference
98 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18475).
100 2011-04-02 6.6.9-3 Cristy <quetzlzacatenango@image...>
101 * Added -statistic Gradient
103 2011-04-01 6.6.9-3 Cristy <quetzlzacatenango@image...>
104 * New version 6.6.9-3.
106 2011-04-01 6.6.9-3 Cristy <quetzlzacatenango@image...>
107 * Set the caption height correctly for missing row geometry (reference
108 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18447).
110 2011-03-31 6.6.9-2 Cristy <quetzlzacatenango@image...>
111 * New version 6.6.9-2.
113 2011-03-30 6.6.9-2 Glenn Randers-Pehrson <glennrp@image...>
114 * Revised the png decoder to store the PNG IHDR and other known PNG
115 chunk data as properties, for later retrieval and reporting by "identify",
116 so users can easily and reliably discover the color-type, bit-depth, etc
117 that were in the input PNG datastream.
118 * The PNG decoder sometimes set images with more than 256 different
119 gray-alpha pixels to storage_class=PseudoClass with an incorrect colormap.
121 2011-03-30 6.6.9-2 Anthony Thyssen <A.Thyssen@griffith...>
122 * Add a "Resize" distortion method (distort equivalent of -resize).
123 * Special CLI handling so -distort Resize takes a "geometry" argument.
125 2011-03-29 6.6.9-2 Cristy <quetzlzacatenango@image...>
126 * Expand PCL compressed pixel buffer to prevent delta compressed overrun.
128 2011-03-29 6.6.9-1 Cristy <quetzlzacatenango@image...>
129 * New version 6.6.9-1.
131 2011-03-29 6.6.9-1 Anthony Thyssen <A.Thyssen@griffith...>
132 * Fix AdaptiveResizeImage() to use 'Mesh' Interpolation, and fix its
133 coordinate handling, as originally defined.
135 2011-03-29 6.6.9-1 Cristy <quetzlzacatenango@image...>
136 * Support -statistic standard-deviation option.
137 * Patch for coders/dcm.c so it compiled with HDRI enabled.
139 2011-03-28 6.6.9-0 Cristy <quetzlzacatenango@image...>
140 * New version 6.6.9-0.
142 2011-03-28 6.6.9-0 Cristy <quetzlzacatenango@image...>
143 * Optimize bilinear interpolation.
144 * Remove version from etc folder and instead use /etc/ImageMagick.
146 2011-03-28 6.6.9-0 Anthony Thyssen <A.Thyssen@griffith...>
147 * Separated complex cropping function from TransformImage() as a new
148 function CropImageToTiles(). This new function returns either the
149 new cropped image, or a list of tiles, according to geometry, without
150 replacing the source image. The Source image may be part of a larger list
151 of images, without the function 'losing' the other images of the list.
153 2011-03-27 6.6.8-10 Cristy <quetzlzacatenango@image...>
154 * New version 6.6.8-10.
156 2011-03-27 6.6.8-10 Anthony Thyssen <A.Thyssen@griffith...>
157 * Modified image handling in MogrifyImages() and MogrifyImage()
158 which improves overall handling, and allows correct %p, %n and the
159 %[fx:..] 't' and 'n' escape usage to work correctly.
160 * Added -duplicate as a multi-image sequence operator
162 2011-03-26 6.6.8-9 Cristy <quetzlzacatenango@image...>
163 * New version 6.6.8-9.
165 2011-03-25 6.6.8-9 Cristy <quetzlzacatenango@image...>
166 * Add InterpolateMagickPixelPacket() method.
167 * Add support for the %[opaque] property.
169 2011-03-25 6.6.8-8 Cristy <quetzlzacatenango@image...>
170 * New version 6.6.8-8.
172 2011-03-25 6.6.8-8 Cristy <quetzlzacatenango@image...>
173 * Fix memory access bug in CloneString() (reference
174 http://www.imagemagick.org/discourse-server/viewtopic.php?f=2&t=18382).
175 * Avoid infinite loop when no space is available in MagickFormatCaption().
177 2011-03-25 6.6.8-8 Anthony Thyssen <A.Thyssen@griffith...>
178 * Removed the fix for %p and %n escapes, as it was not working right
180 2011-03-24 6.6.8-7 Cristy <quetzlzacatenango@image...>
181 * New version 6.6.8-7.
183 2011-03-24 6.6.8-7 Cristy <quetzlzacatenango@image...>
184 * Add support for 16-bit DCM short ints (reference
185 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18371).
187 2011-03-23 6.6.8-7 Anthony Thyssen <A.Thyssen@griffith...>
188 * Another fix for -sparse-color and unused color channels
189 * Finalize the -duplicate option created by Cristy
190 * Fix of segmentation fault for second image in %[fx:..] during info:
191 (Bug in AcquireFxInfo(), as given start image is not first image)
193 2011-03-21 6.6.8-7 Glenn Randers-Pehrson <glennrp@image...>
194 * Revised the PNG8 encoder to use 50% threshold instead of 0% when
195 reducing transparency to binary. Collapse all resulting fully transparent
196 colors into one (the background color), to reduce the compressed filesize.
197 * First try the 4-4-4-1 and 3-3-3-1 palettes instead of 3-3-2-1, to preserve
198 colors (especially gray) better, when reducing to PNG8.
199 * Force the PNG encoder to return image->matte==MagickTrue when the
200 format is RGBA or GA or if the tRNS chunk is present, even when the
201 image is fully opaque (reference
202 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18349).
204 2011-03-21 6.6.8-6 Cristy <quetzlzacatenango@image...>
205 * New version 6.6.8-6.
207 2011-03-21 6.6.8-6 Glenn Randers-Pehrson <glennrp@image...>
208 * Re-enabled reduction of grayscale images (color-type 0) to 2 or 4 bits
209 when appropriate (reference
210 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18098).
211 * The "-define PNG:color-type=4" option did not always force the PNG
212 encoder to write an all-opaque alpha channel (reference
213 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18349).
215 2011-03-14 6.6.8-6 Cristy <quetzlzacatenango@image...>
216 * Fixed memory leak for PDF and Bitmap PSD RLE support (reference
217 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18317).
218 * Support the -statistic option: replace each pixel with corresponding
219 statistic from the neighborhood.
220 * Add support for -duplicate option.
221 * Move configuration files from /usr/share and /usr/lib to /etc and /var.
222 * Do not cache the results of fx: otherwise -format
223 '%[fx:rand()] %[fx:rand()]' returns the same random numbers.
225 2011-03-18 6.6.8-6 Anthony Thyssen <A.Thyssen@griffith...>
226 * Replaced Minus and Divide Composition methods with Dst and Src
227 equivalents. Now users can decide how these non-commutative mathematical
228 operators are applied to the images being composited.
229 * Fix the percent escape values for %p, %n and %[fx:t], %[fx:n] to
230 respectively mean the current images index and the total number of
231 images within the current image sequence.
233 2011-03-17 6.6.8-5 Anthony Thyssen <A.Thyssen@griffith...>
234 * Backed out the patch for Variable Blur Composition that was added
235 2011-02-13 v6.6.7-7, until I can re-think the problem.
236 The existing fix was failing to do circular blurs correctly.
238 2011-03-14 6.6.8-5 Glenn Randers-Pehrson <glennrp@image...>
239 * Fixed a rounding/truncation error while writing the pHYs chunk in the
241 * Don't write text-encoded profile when "-define PNG:exclude-chunk=text,ztxt"
242 is present (reference
243 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17086 and
244 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18225).
246 2011-03-14 6.6.8-5 Cristy <quetzlzacatenango@image...>
247 * Add support for the WebP image format.
249 2011-03-14 6.6.8-5 Anthony Thyssen <A.Thyssen@griffith...>
250 * Ensured that -sparse-color preserves unused channels when
251 channel limited. Before this unused channels would be reset to black.
253 2011-03-11 6.6.8-4 Glenn Randers-Pehrson <glennrp@image...>
254 * Don't try to store a bKGD chunk in a PNG8 when there are already
255 256 colors in the palette and the background colors is not in that
257 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18199);
258 * The "-define PNG:exclude-chunk=bKGD" option was also excluding
259 the text chunks. (reference
260 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18253).
262 2011-03-10 6.6.8-4 Cristy <quetzlzacatenango@image...>
263 * Fx is a mathematical function. Do not treat transparency as black.
264 * No image scene suffix for filenames that include a single bracket (reference
265 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18267).
267 2011-03-10 6.6.8-3 Cristy <quetzlzacatenango@image...>
268 * New version 6.6.8-3.
270 2011-03-10 6.6.8-3 Cristy <quetzlzacatenango@image...>
271 * Boost causes an ambiguity with ssize_t when building PythonMagick. Add
272 patch from Arfrever@gento... to fix the build exception.
274 2011-03-09 6.6.8-2 Cristy <quetzlzacatenango@image...>
275 * Support the Radiance HDR image format.
276 * Update the offset in the black channel when sharpening to avoid incorrect
278 * Do not use GenericReadMethod for TIFF images with 64-bits per sample.
280 2011-03-06 6.6.8-2 Glenn Randers-Pehrson <glennrp@image...>
281 * Throw error message when the requested color-type or bit-depth
282 cannot be written by the PNG encoder (error was being thrown
283 into the wrong image structure). (Reference
284 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18162).
285 * Don't write a PNG text chunk with "density" keyword that overrides the
286 PNG pHYs chunk, if the pHYs chunk was not excluded (reference
287 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18253).
288 * Ignore any PNG text chunk with a "density" keyword found by the PNG
289 decoder, if the PNG datastream also contains a pHYs chunk.
291 2011-03-06 6.6.8-1 Cristy <quetzlzacatenango@image...>
292 * New version 6.6.8-1.
294 2011-03-05 6.6.8-1 Cristy <quetzlzacatenango@image...>
295 * Support PSD files with one layer and one composite layer.
296 * We must cast a Quantum type when bit shifting and HDRI is enabled.
298 2011-03-05 6.6.8-0 Cristy <quetzlzacatenango@image...>
299 * New version 6.6.8-0.
301 2011-02-27 6.6.8-0 Cristy <quetzlzacatenango@image...>
302 * Add support for the -mode option.
304 2011-02-27 6.6.8-0 Glenn Randers-Pehrson <glennrp@image...>
305 * Fix scaling of new color-reduction method in the PNG encoder (16-bit
306 images were scaled down to 0 or 1, or nearly black).
307 * Delay opening the PNG output blob until the PNG encoder is ready
308 to write the IHDR chunk, to avoid writing zero-length PNG files when
309 errors are found while building the palette. (reference
310 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18162).
312 2011-02-25 6.6.7-10 Cristy <quetzlzacatenango@image...>
313 * New version 6.6.7-10.
315 2011-02-23 6.6.7-10 Cristy <quetzlzacatenango@image...>
316 * Avoid seg fault in AppendImages() when one image is in the RGB colorspace
317 but the other is in the CMYK colorspace.
318 * Get rid of 'respect_parenthesis defined but not used' warnings (reference
319 http://www.imagemagick.org/discourse-server/viewtopic.php?f=2&t=18173).
321 2011-02-22 6.6.7-10 Glenn Randers-Pehrson <glennrp@image...>
322 * Write sub-8-bit grayscale PNG images as palette-indexed PNG images. This
323 usually makes smaller files anyhow.
324 * Eliminated a number of redundant tests for gray images in the PNG encoder.
325 * Removed now-unused IsMonochromeImage() function from coders/png.c
326 * Scan the colormap instead of all of the pixels, when possible, to
327 determine whether the image received by the PNG encoder is grayscale
329 * Avoid reading from the colormap in coders/png.c when it is NULL (reference
330 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18162).
331 * Add a check whether the PNG "cheap transparency" criteria are met. That
332 is, there is a single transparent color, no semitransparent colors, and
333 no opaque color that has the same RGB components as the transparent
334 color. If those aren't met, a color that is transparent in one pixel
335 and opaque in another would always be rendered as transparent, so we
336 must write a PNG colortype that has an alpha channel (reference
337 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18167).
339 2011-02-22 6.6.7-9 Cristy <quetzlzacatenango@image...>
340 * New version 6.6.7-9.
342 2011-02-22 6.6.7-9 Glenn Randers-Pehrson <glennrp@image...>
343 * Disabled reduction of grayscale images (color-type 0) to less than 8 bits
344 when writing because this sometimes produced incorrect output (reference
345 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18098).
347 2011-02-21 6.6.7-9 Cristy <quetzlzacatenango@image...>
348 * Check image has properties before accessing the splay tree (reference
349 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18136).
351 2011-02-15 6.6.7-8 Cristy <quetzlzacatenango@image...>
352 * New version 6.6.7-8.
354 2011-02-14 6.6.7-8 Glenn Randers-Pehrson <glennrp@image...>
355 * The PNG encoder should ignore bogus q->opacity values when image->matte
356 is MagickFalse (reference
357 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18067).
359 2011-02-14 6.6.7-8 Cristy <quetzlzacatenango@image...>
360 * Use implicit image format when explicit format is bogus (e.g.
361 02.13.11-18:43:58.png now writes as PNG).
362 * Fix problem with 4GB file seeks on a 32-bit OS.
364 2011-02-13 6.6.7-7 Anthony Thyssen <A.Thyssen@griffith...>
365 * Fixed Variable blur to handle small (< 1.0 sigma) blurs generated
366 by the blur map being used, rather than just 'cutoff' suddenly.
368 2011-02-08 6.6.7-7 Cristy <quetzlzacatenango@image...>
369 * Support 16-bit per pixel YUV image files.
370 * Fix off-by-one error in PosterizeImage().
371 * Posterize now distributes color uniformly (reference
372 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17623).
373 * Add -smush option (reference
374 http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=17953).
375 * Repair memory leak in the display program.
377 2011-02-07 6.6.7-6 Cristy <quetzlzacatenango@image...>
378 * Fix bug in carg() define when HAVE_COMPLEX is not defined (reference
379 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18030).
381 2011-02-06 6.6.7-6 Anthony Thyssen <A.Thyssen@griffith...>
382 * Default sigma for Gauusian resize filter is now 1/2 for both
383 orthogonal resize and cylindrical EWA distortions.
385 2011-02-02 6.6.7-5 Cristy <quetzlzacatenango@image...>
386 * Check if the font is null in RenderFreetype() to prevent fault (reference
387 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17890).
388 * Eliminate fault when reading WMF image files (reference
389 http://www.imagemagick.org/discourse-server/viewtopic.php?f=2&t=17971).
390 * Support multi-page transparent Postscript and PDF image files.
391 * The compare fuzz metric now returns the same correct value for
392 'xc:white xc:blue -alpha off' and 'xc:white xc:blue -alpha on'.
394 2011-01-29 6.6.7-4 Paul Heckbert <ph@cs.cm...>
395 * Move coders/tiff.c conditional compile to define TIFF exception /
396 semaphore / key when TIFF delegate is disabled.
398 2011-01-29 6.6.7-4 Glenn Randers-Pehrson <glennrp@image...>
399 * Renamed variables, macros, and functions defined/declared in coders/png.c
400 that were in the libpng namespace (beginning with "png_" or "PNG_").
402 2011-01-25 6.6.7-3 Glenn Randers-Pehrson <glennrp@image...>
403 * Removed a call to GetNumberColors() from the PNG encoder that was
404 only there for debugging purposes and was consuming a huge amount
405 of CPU time. (reference
406 http://www.imagemagick.org/discourse-server/viewtopic.php?f=2&t=17799).
407 * Sometimes black was still written as transparent, when the PNG
408 encoder received an image with image->matte==true but no transparent
409 pixels were present. (reference
410 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17913);
412 2011-01-24 6.6.7-3 Cristy <quetzlzacatenango@image...>
413 * Remove memory leak from ThrowFileException() macro (reference
414 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17908).
415 * Multiple blue error count by 'count' in ClassifyImageColors()
416 * Add support for the AAI image format.
418 2011-01-22 6.6.7-2 Cristy <quetzlzacatenango@image...>
419 * Accept quoted file paths in indirect file references (e.g. @myFiles.txt).
421 2011-01-19 6.6.7-2 Glenn Randers-Pehrson <glennrp@image...>
422 * Changed the PNG encoder's "transparent_color" from a UShortPixelPacket
423 to LongPixelPacket and made the default (65537,65537,65537), which
424 can never occur in the PNG image data. Previously the default was
425 (0,0,0) and black pixels would be rendered as as transparent when
426 no tRNS chunk was present in the input, which has caused problems
427 with some test cases since version 6.6.6-10.
428 * Improved the PNG_BUILD_PALETTE section to count opaque, transparent,
429 and semitransparent pixels separately. Previously it wasn't always
430 possible to determine if there was a single fully-transparent color,
431 to decide whether to write an RGBA or Gray-Alpha image or an RGB or
432 Gray image with a tRNS chunk.
434 2011-01-15 6.6.7-1 Cristy <quetzlzacatenango@image...>
435 * Do not reset image next / previous when detach argument is false for
437 * Inline cropping no longer fails for inline raw images (e.g.
438 -size 640x480 -depth 8 'gray:logo[100x100+200+200]').
440 2011-01-14 6.6.7-1 Glenn Randers-Pehrson <glennrp@image...>
441 * Don't let the PNG encoder try to sort the colormap when there are more
442 than 256 colors in the image. (reference
443 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17834).
445 2011-01-10 6.6.7-1 Cristy <quetzlzacatenango@image...>
446 * Accept escaped % in output filename (reference
447 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17810).
449 2011-01-08 6.6.7-1 Glenn Randers-Pehrson <glennrp@image...>
450 * Quieted some inconsequential warnings in the PNG codec due to a
451 change in the type of the PNG iCCP profile from png_charp to png_bytep
454 2011-01-03 6.6.7-0 Cristy <quetzlzacatenango@image...>
455 * Handle negative heights for ICO images.
457 2011-01-02 6.6.7-0 Glenn Randers-Pehrson <glennrp@image...>
458 * Recent changes sometimes caused the PNG encoder to select colortype=2
459 (Truecolor) instead of 0 (Grayscale) for grayscale images. This made
460 the filesize larger than necessary and caused some of the PerlMagick
463 2011-01-01 6.6.6-10 Glenn Randers-Pehrson <glennrp@image...>
464 * The PNG decoder now checks whether the image actually has any transparency
465 when the input file contains an alpha channel or a tRNS chunk. (Reference
466 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17748)
468 2010-12-26 6.6.6-8 Cristy <quetzlzacatenango@image...>
469 * -posterize fails with more than 40 levels (reference
470 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17741).
471 * Add support for the MacPaint image format.
472 * Eliminate spurious 'invalid colormap index' exception for 16-bit SGI images
473 (bug report by steven.sittser@fligh...).
474 * Fix user data length for the CIN image format.
476 2010-12-21 6.6.6-7 Glenn Randers-Pehrson <glennrp@image...>
477 * Use a clone instead of the main image in coders/png.c, so the image
478 can still be used later on without being affected by changes made by
480 * Added PNG:exclude-chunk and PNG:include-chunk defines.
481 * Revised the -strip option so it behaves as though
482 "-define PNG:include-chunk=none,gama" had appeared on the commandline.
483 * Avoid writing PNG ancillary chunks in the PNG/MNG/JNG encoder while
484 generating the alpha channel for a JNG image.
486 2010-12-21 6.6.6-7 Anthony Thyssen <A.Thyssen@griffith...>
487 * Removed the forced interpolation setting in AcquireResampleFilterThreadSet
488 It prevented user defined interpolation settings for -clut, and possibly
491 2010-12-17 6.6.6-6 Chris Madison <madisonblu@gmail...>
492 * Add LZMA compression support to ImageMagick.
493 * Eliminate seg-fault in MvgPrintf().
495 2010-12-17 6.6.6-6 Glenn Randers-Pehrson <glennrp@image...>
496 * Eliminated a redundant quantization step in the PNG encoder.
497 * Untangled a confusing but apparently harmless improper loop nesting
499 * Eliminated redundant "IsGray()" tests from the PNG encoder.
501 2010-12-14 6.6.6-6 Cristy <quetzlzacatenango@image...>
502 * -format "%[fx:u.p{5,5}]" no longer reports parse exception (reference
503 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17678).
505 2010-12-10 6.6.6-5 Glenn Randers-Pehrson <glennrp@image...>
506 * Make the PNG encoder always rebuild the palette, to avoid losing
507 transparency when it is out of sync with the pixel data (reference
508 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17655).
509 * Eliminated CompressColormapTransFirst() since the palette is already
510 compressed and sorted by opacity now when it's recreated.
512 2010-12-10 6.6.6-5 Cristy <quetzlzacatenango@image...>
513 * Account for virtual canvas for the -flip / -flop options (reference
514 http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=17626).
515 * Also for -transpose and transverse options
516 * Support -metric fuzz option.
518 2010-12-09 6.6.6-4 Anthony Thyssen <A.Thyssen@griffith...>
519 * Replace IsMagickColorSimilar() which provides the Fuzz Factor threshold
520 function. Note function does not calculate 'distance' in total but
521 short-circuits when threshold is reached for faster processing.
522 * Ordered Dithered handling of Alpha channel was incorrect - fixing
523 Bug was introduced v6.6.5-6
525 2010-12-03 6.6.6-3 Glenn Randers-Pehrson <glennrp@image...>
526 * Fixed two more cases where the PNG encoder lost transparency (reference
527 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17516).
529 2010-12-01 6.6.6-2 Cristy <quetzlzacatenango@image...>
530 * Affine multiplication reversed when translating (reference
531 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17570).
533 2010-11-26 6.6.6-2 Glenn Randers-Pehrson <glennrp@image...>
534 * Revised the "c7x7b" and "c7x7w" ordered-dither maps to be complementary
537 2010-11-27 6.6.6-1 Cristy <quetzlzacatenango@image...>
538 * Add support for -evaluate-sequence median.
540 2010-11-26 6.6.6-0 Glenn Randers-Pehrson <glennrp@image...>
541 * Fixed two more cases where the PNG encoder lost transparency (reference
542 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17516).
544 2010-11-23 6.6.6-0 Cristy <quetzlzacatenango@image...>
545 * The policy.xml sets not-to-exceed resource values (e.g. policy memory limit
546 1GB, -limit 2GB exceeds policy maximum so memory limit is 1GB).
547 * Support NCC (normalized cross correlation) compare metric.
549 2010-11-21 6.6.5-10 Cristy <quetzlzacatenango@image...>
550 * Fix PNG coder compile error when HDRI is enabled.
552 2010-11-17 6.6.5-9 Glenn Randers-Pehrson <glennrp@image...>
553 * Many of the problems with the PNG encoder have been fixed (reference
554 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16490).
555 * The "-type Optimize" option is now deprecated. If present, it is treated
556 by the PNG encoder the same as if the type were undefined. Optimization
557 is now always performed. No other formats used the "type Optimize" option.
558 * Merged redundant code into LosslessReduceDepth() function in the PNG codec.
560 2010-11-14 6.6.5-9 Cristy <quetzlzacatenango@image...>
561 * The splice option no longer throws spurious "pixels are not authentic"
563 * Thread the -adaptive-resize option.
564 * Set XBM coder height to height not width.
566 2010-11-14 6.6.5-9 Nicolas Robidoux <nicolas.robidoux@gmai...>
567 * Lanczos2Sharp blur tweaked. New blur = 0.9549963639785485.
569 2010-11-13 6.6.5-9 Nicolas Robidoux <nicolas.robidoux@gmai...>
570 * LanczosSharp blur tweaked to minimize worst case deviation from "perfect
571 preservation of images which only vary horizontally (or vertically)" under
572 no-op. New blur = 0.9812505644269356.
574 2010-11-08 6.6.5-8 Nicolas Robidoux <nicolas.robidoux@gmai...>
575 * Missing logical operator in tiff.c.
577 2010-11-08 6.6.5-8 Cristy <quetzlzacatenango@image...>
578 * Only save TIFF image with 1-bit depth if there is no alpha channel.
579 * Abandon PSD composite if layer is available.
580 * %[fx:mean] is the mean of the default channels (all but opacity) (reference
581 http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=17432).
583 2010-10-29 6.6.5-6 Glenn Randers-Pehrson <glennrp@image...>
584 * Added 5x5, 6x6, and 7x7 ordered-dither level maps.
586 2010-10-30 6.6.5-5 Cristy <quetzlzacatenango@image...>
587 * Do not read configure files in the current directory for the "installed"
588 version of ImageMagick.
589 * Allow numeric characters in the XPM basename (reference
590 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17385).
592 2010-10-29 6.6.5-4 Glenn Randers-Pehrson <glennrp@image...>
593 * Revised PNG palette optimization
594 * Added some debug logging in coders/png.c.
596 2010-10-28 6.6.5-3 Nicolas Robidoux <nicolas.robidoux@gmai...>
597 * More precise blur values for Lanczos2Sharp and LanczosSharp.
598 * Added location of first Mitchell crossing (=8/7) to the filters data
601 2010-10-28 6.6.5-2 Anthony Thyssen <A.Thyssen@griffith...>
602 * Added Lanczos2D* filters now named Lanczos2*
603 * Reorganization of AcquireFilter() to make it work better
605 2010-10-25 6.6.5-1 Nicolas Robidoux <nicolas.robidoux@gmai...>
606 * Clearer EWA filters (LanczosSharp etc) comments.
608 2010-10-25 6.6.5-1 Anthony Thyssen <A.Thyssen@griffith...>
609 * Added LanczosSharp (3-lobe Lanczos with sharpening)
610 * Filter sharpening factors are also always applied regardless of usage.
612 2010-10-24 6.6.5-1 Nicolas Robidoux <nicolas.robidoux@gmai...>
613 * CubicBC filter formulas simplified by constant folding. In
614 particular, P1 coefficient (always zero) removed from coeff.
616 2010-10-22 6.6.5-1 Nicolas Robidoux <nicolas.robidoux@gmai...>
617 * Revert the Robidoux filter to a Keys cubic with C=(108 sqrt 2-29)/398
618 (as already specified in the documentation).
620 2010-10-14 6.6.5-1 Cristy <quetzlzacatenango@image...>
621 * Ignore PS bounding box offsets if -page is set.
622 * Use #pragma omp master for dumping single threaded debugging information
623 (single caused a fault).
624 * Add support for -evaluate exp.
626 2010-10-12 6.6.5-0 Anthony Thyssen <A.Thyssen@griffith...>
627 * Added "filter:sigma" expert setting defining the 'sigma' for the Gaussian
628 filter only. This is similar in action to 'blur' but only for Gaussians,
629 and does not modify the filters support, allowing you to set a very small
630 sigma, without the function 'missing' all pixels.
631 (This will allow future adjustment of Gaussians for variable blur mapping)
633 2010-10-10 6.6.5-0 Cristy <quetzlzacatenango@image...>
634 * Patch for DrawableRotation() and DrawableTranslation() (reference
635 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17246).
636 * The webp format requires the webpconv delegate program (experimental).
638 2010-10-05 6.6.5-0 Anthony Thyssen <A.Thyssen@griffith...>
639 * Replaced "Robidoux" with Cubic 'Keys' filter that is near equivalent to
640 the previous sharped "Lanczos2D" filter. (C=0.31089212245300069)
641 This also is very similer to a Mitchell filter but specifically designed
642 for EWA use and is the new default filter for Distorting Images.
643 * Original sharpened Lanczos2D filter now called "Lanczos2Dsharp"
645 2010-10-08 6.6.4-10 Jerry Gay <jerry.gay@gmail..>
646 * Autodetect file type support in Makefile.PL to prevent test failures
648 2010-10-05 6.6.4-10 Anthony Thyssen <A.Thyssen@griffith...>
649 * Added new filter 'Lanczos2D' a 2-lobe Lanczos as defined by
650 Andreas Gustafsson in his thesis "Interactive Image Warping" (page 24)
651 http://www.gson.org/thesis/warping-thesis.pdf
652 * Added filter "Robidoux" which is a slightly sharpened version of the
653 "Lanczos2D" filter (blur=0.958033808) specifically designed to be less
654 'blurry' for horizontal and vertical lines in no-op distortions.
656 2010-10-05 6.6.4-10 Cristy <quetzlzacatenango@image...>
657 * Add support for "pattern:vertical2" and "pattern:horizontal2".
658 * Add support for "pattern:vertical3" and "pattern:horizontal3".
659 * Properly handle PSD layers with negative offsets.
661 2010-10-03 6.6.4-9 Cristy <quetzlzacatenango@image...>
662 * Fix memory assertion with --enable-embeddable (reference
663 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17201).
664 * Don't permit access to pixels when pinging an image (reference
665 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17194).
667 2010-10-02 6.6.4-9 Anthony Thyssen <A.Thyssen@griffith...>
668 * Added sqrt(2) blurring default for Gaussian Filter if used as
669 a Cylindrical EWA filter. This resulted removing the last aliasing
670 issue that was present in tests for Gaussian EWA resampling. Of course
671 it is still a very blurry filter for default use in EWA.
672 * Adjusted Variable Mapping Blur Composition so user arguments actual
673 relate properly to the sigma of the blur for a maximum mapping value.
674 * Fix horizon anti-alising for output-scaled perspective distortions.
675 * 'Bessel' filter is now offically and more accuritally named 'Jinc'
676 however 'Bessel' while not visible as a filter option can still be used
677 as an internal alias for 'Jinc'.
679 2010-09-28 6.6.4-8 Nicolas Robidoux <nicolas.robidoux@gmai...>
680 * Chantal Racette double checked the bounding parallelogram computation
681 in resample.c (and I tightened the comments).
683 2010-09-28 6.6.4-8 Cristy <quetzlzacatenango@image...>
684 * Temporary files not always deleted (reference
685 http://www.imagemagick.org/discourse-server/viewtopic.php?f=2&t=15960).
687 2010-09-28 6.6.4-8 Anthony Thyssen <A.Thyssen@griffith...>
688 * Bug fix for -filter point distorts (occasional generating black pixels)
690 2010-09-27 6.6.4-8 Nicolas Robidoux <nicolas.robidoux@gmai...>
691 * Simplified the ClampUpAxes code, the use of its outputs, its comments,
692 and credited Craig DeForest for the "clamp singular values" idea.
693 * No reason to have "insane" precision Sinc in resize.c: Use
694 the 1.2e-12 max. abs. relative error version for Q64 as well as Q32.
696 2010-09-27 6.6.4-8 Anthony Thyssen <A.Thyssen@griffith...>
697 * Replace the blurry "High Quality EWA" technique with a 'Clamped EWA'
698 for Distort Resampling. This makes -distort a whole lot nicer
699 and allows for the use of better cylindrical filters.
701 2010-09-26 6.6.4-7 Anthony Thyssen <A.Thyssen@griffith...>
702 * Fix Point filter for ResizeImage() caused by support limiting the
703 Box weighting function.
705 2010-09-26 6.6.4-6 Cristy <quetzlzacatenango@image...>
706 * Don't allow resize filter weights to go to zero (reference
707 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17132).
709 2010-09-24 6.6.4-6 Nicolas Robidoux <nicolas.robidoux@gmai...>
710 * Now that MagickPIL is a MagickRealType, some casts are unneeded.
712 2010-09-21 6.6.4-6 Cristy <quetzlzacatenango@image...>
713 * Do not break words if caption size is absolute (reference
714 http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=17123).
715 * Don't define HAVE_THREADS for --without-threads configure script option.
717 2010-09-20 6.6.4-5 Nicolas Robidoux <nicolas.robidoux@gmai...>
718 * Modified "magick/resize.c" so that MagickPIL is a MagickRealType number.
719 Some computations were needlessly done in long double precision because
720 PIL forced an automatic upcast wherever it appeared. Changed its name to
721 MagickREALTYPEPI. <- This was later reverted back to MagickPIL.
722 * Modified "magick/resize.c" so that Bohman uses one trig call + one sqrt
723 call instead of two trig calls.
725 2010-09-20 6.6.4-5 Anthony Thyssen <A.Thyssen@griffith...>
726 * modified "magick/resample.c" to allow use of either EWA or HQEWA (default)
727 * Removed LanczosFast from supported filters (SincFast*SincFast is faster)
729 2010-09-19 6.6.4-5 Cristy <quetzlzacatenango@image...>
730 * If IPTC profile is not embedded in an 8bim resource, declare it IPTC
732 * Support %[version] and %[copyright].
733 * Improve performance of the pixel cache.
735 2010-09-18 6.6.4-4 Cristy <quetzlzacatenango@image...>
736 * Automatically set the quantum depth to 16 for HDRI.
738 2010-09-16 6.6.4-2 Cristy <quetzlzacatenango@image...>
739 * IPTC profile not always wrapped properly inside an 8BIM profile.
740 * TIFF tile geometry must be divisible by 16.
742 2010-09-15 6.6.4-2 Anthony Thyssen <A.Thyssen@griffith...>
743 * Rename of SincPolynomial to SincFast for easier user understanding
744 * Ditto for LanczosChebyshev to LanzcosFast
746 2010-09-14 6.6.4-2 Anthony Thyssen <A.Thyssen@griffith...>
747 * Switch default resize filters to using the faster SincPolynomial
748 filter by default internally. However 'Sinc' will still use the
749 Trigonometric function, and can be used to assign the trig version
750 of Sinc() to filters using the filter expert options.
751 * The default filter for 'distort' was found to be a very blurry inaccurate
752 filter function. It was removed and replaced with a correct Gaussian
753 filter (as used by resize)
754 * Added a switch so that "-interpolate filter" will force the use of
755 a cylindrical filter for ALL pixels in distorted images. That is you can
756 use that switch to use a cylindrical filter even for images that are
757 being enlarged by the distortion. However EWA is still currently using
758 a fixed 2.0 sampling radius. This switch complements the use of "-filter
759 point" which turns off EWA filters in favor of interpolation for all
760 pixels in a distorted image. BOTH switches should not be used together.
761 * A bug in the support radius of the EWA resampling function was found,
762 now that correctly defined resize filters are being used. Suddenly Normal
763 Gaussian distortions are not so blurry, and tests with distortions of
764 the 'Rings' image show extremely good and clear results, with only minimal
765 blurring. The filter 'blur' expert option can be used to adjust this
768 The above represents a major improvement forward in the quality of the
769 image distortion operator. But near-unity distortions (no scaling) are
772 2010-09-13 6.6.4-2 Cristy <quetzlzacatenango@image...>
773 * Don't negate the geometry offset for the -extent option.
775 2010-09-09 6.6.4-1 Cristy <quetzlzacatenango@image...>
776 * The RGBO format is now listed as a supported format.
778 2010-09-07 6.6.4-1 Anthony Thyssen <A.Thyssen@griffith...>
779 * Added the Nicolas Robidoux and Chantal Racette Lanczos resize filter
780 function as "LanczosChebyshev" as faster alternative to Lanczos.
781 * Re-code Nicolas Robidoux and Chantal Racette Polynomial Approximation of
782 the Sinc Trigonometric resize filter, as a proper filter to allow
783 direct comparision and speed testing of the filter.
784 * Expanded the "-set option:filter:verbose 1" output, so as to also include
785 the actual functions and other values that were used to create the filter.
787 2010-09-02 6.6.4-0 el_supremo <digipete@shaw...>
788 * Repair a few incorrect LocaleNCompare() calls (ttf.c, ps.c).
790 2010-08-31 6.6.4-0 Cristy <quetzlzacatenango@image...>
791 * Path no longer closed if join style is round (reference
792 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16943).
793 * Add case for BGRQuantum to GetQuantumExtent().
794 * Support no compression on PCX write.
796 2010-08-23 6.6.3-10 Cristy <quetzlzacatenango@image...>
797 * Fixed bug in the raw BGRA coders (reference
798 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16880).
799 * Fix off-by-one error in the PSD coders.
800 * Nicolas Robidoux with the assistance of Chantal Racette contribute an
801 approximation of the sinc function over the interval [-3,3].
802 * Eliminate a small memory leak in LevelizeImageChannel() (reference
803 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16951).
804 * Recognize -fx logtwo (reference
805 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16958).
807 2010-08-15 6.6.3-7 Cristy <quetzlzacatenango@image...>
808 * Throw exception if image size differs for the compare program but the
809 -subimage-search option is not specified.

849 2010-07-25 6.6.3-1 Glenn Randers-Pehrson <glennrp@image...>
850 * Don't "ping" a PNG image if it is embedded in a MNG. Otherwise the
851 reader tries to read MNG chunks from the interior of the embedded PNG,
852 resulting in an erroneous "corrupted image" message.

860 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16662).
862 2010-07-07 6.6.3-1 Glenn Randers-Pehrson <glennrp@image...>
863 * The PNG decoder failed to handle the tRNS chunk properly for grayscale
864 images where the PNG bit_depth was not the same as the quantum depth,
865 and the transparent color was not black.
867 2010-07-01 6.6.3-0 Chris Madison <madisonblu@gmail...>
868 * Pinging the DJVU image format no longer faults.
869 * Check for time-limit-exceeded in only one thread.
870 * Reading filenames from a file (e.g. @filenames) no longer includes the
871 utility name (side effect of StringToArgv() method).
873 2010-06-28 6.6.2-10 Cristy <quetzlzacatenango@image...>

963 2010-05-23 6.6.2-0 Anthony Thyssen <A.Thyssen@griffith...>
964 * Third Re-write of MorphologyApply() to better handle compound methods.
965 * Implemented -set option:morphology:compose for merging results of
966 multiple kernels. "None" means re-iterate results with next kernel.
967 While "Undefined" means to use the internal default for a method.
968 Thinning, Thickening, HitAndMiss, Convolve, Correlate defaults to "None"
969 while HitAndMiss defaults to "Lighten" (union of all kernel results).
970 Other morphology methods defaults still to be decided.
971 * Added HitAndMiss Kernel: Ridges (find ridges and pixel width lines)
972 * Rotation Expansion of single kernels '^' and '@' flags in arguments
973 EG: -set option:showkernel 1 -morphology Convolve 'Blur:0x2^'
974 * ExpandKernelInfo() (rotation expand) now groks symmetrical kernels.
975 So the above will only produce a list of 2 kernels, not 4 kernels
977 2010-05-18 6.6.2-0 Anthony Thyssen <A.Thyssen@griffith...>
978 * Separation of internal function MorphologyApply() from
979 MorphologyImageChannel() to calls to convolve without user settings.
980 * Rewrite of MorphologyApply() to output better 'verbose' messages
981 * Better handling of Gaussian tyle filters (bug fixes)
982 * Bug fix and optimization of kernel size calculations in "gem.c"

995 * PSD images require a proper layer to support an alpha channel.
996 * Enable PFM endian support.
997 * Add context to -border for montage. Inside the parenthesis it adds a border
998 to the image otherwise it sets the border for the layout manager.
999 * 24-bit BMP images are not colormapped even if header colors != 0.
1000 * Set DPX user data like this: -set profile dpx:userdata.txt.
1001 * Make sure Lab => RGB => Lab survives the round trip.
1003 2010-05-15 6.6.1-10 Cristy <quetzlzacatenango@image...>
1004 * Use ScaleCharToQuantum() in coders/src.c (reference
1005 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16229).
1006 * Don't clamp HDRI EXR pixels.

1030 * Added many new kernels for HitAndMiss and Convolution
1031 Sobel, Laplacian, Cross, Peaks, Corners, LineEnds, LineJunctions,
1032 ConvexHull (for Thicken), Skeleton (for Thinning)
1034 2010-05-08 6.6.1-8 Glenn Randers-Pehrson <glennrp@image...>
1035 * Use proper background.index when writing indexed PNG, if the background
1036 color is in the palette.
1038 2010-05-08 6.6.1-7 Cristy <quetzlzacatenango@image...>
1039 * Fix improper 'invalid colormap index' PNG bug.

1043 * Added % and ! modification flags to morphology distance kernel
1044 scaling factor, for easier usage.
1045 * Bug fix for compose math channel handling and morphology diff usage
1047 2010-05-06 6.6.1-6 Cristy <quetzlzacatenango@image...>

1055 for the difference morphology methods. These should now work correctly
1056 for specific channels, and more importantly for alpha shaped morphology.
1058 2010-05-05 6.6.1-6 Glenn Randers-Pehrson <glennrp@image...>
1059 * Fixed bugs with losing the opacity channel while writing some PNG images.

1063 * Simplified and corrected rowbytes calculation in coders/png.c and
1066 2010-05-05 6.6.1-6 Anthony Thyssen <A.Thyssen@griffith...>
1067 * Rename of "Add" and "Subtract" compositions to "ModulusAdd" and
1068 "ModulusSubtract" for more clarity of there functions. Old names
1069 will continue to work as expected.
1070 * Fix "Minus", "ModulusAdd", and "ModulusSubtract" to follow
1071 normal SVG 'Over' blending specifications, (see next for override)
1072 Note that this does NOT include the "Plus" composition method which has
1073 SVG definition for it to use a 'Plus' blending rather than 'Over' blending.
1075 * By default mathematical compositions work as per SVG definition. That is
1076 the results are synchronized with 'Over' alpha-blending (except "Plus"
1077 which uses 'plus' alpha-blending).
1079 By removing the default 'sync' flag from the -channel setting however
1080 Break this inter-channel synchronization and do the mathematical operations
1081 only on the individual channels as specified by the -channel setting.
1082 That is do 'channel' math rather than 'SVG' composition.
1084 With this change you can then use mathematical composition methods on
1085 individual channels or even with the alpha channel of images.

1218 * Respect -type TrueColor when writing gray DPX images.
1219 * Fix problem reading 10-bit grayscale DPX images when scanline length is
1220 not a multiple of 3.
1221 * BMP has an alpha channel, it was treated as an opacity channel.
1223 2010-02-20 6.5.9-10 Cristy <quetzlzacatenango@image...>
1224 * Write 10-bit grayscale DPX images properly.
1226 2010-02-18 6.5.9-8 Cristy <quetzlzacatenango@image...>
1227 * Detect PDF ICCBased colorspace.
1229 2010-02-18 6.5.9-7 Anthony Thyssen <A.Thyssen@griffith...>
1230 * Finalized -set option:convolve:scale kernel normalize/scale option
1232 2010-02-16 6.5.9-7 Cristy <quetzlzacatenango@image...>
1233 * TransformImage() resets the image blob when called in the PICT decoder;
1234 use SetImageExtent() instead.
1236 2010-02-14 6.5.9-6 Cristy <quetzlzacatenango@image...>
1237 * Support PSD RLE compression.
1239 2010-02-13 6.5.9-5 Cristy <quetzlzacatenango@image...>
1240 * The jpeg:extent define sometimes exceeded the specified limit.
1242 2010-02-09 6.5.9-4 Cristy <quetzlzacatenango@image...>
1243 * Resolve "too many open files" (reference
1244 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=15546).
1246 2010-02-08 6.5.9-3 Anthony Thyssen <A.Thyssen@griffith...>
1247 * Added Correlate method which does a Convolve without reflecting the kernel.
1249 2010-02-07 6.5.9-3 Cristy <quetzlzacatenango@image...>
1250 * Initialize grayscale colormap for PSD images.
1252 2010-02-07 6.5.9-3 Anthony Thyssen <A.Thyssen@griffith...>
1253 * Final testing and fixing of basic morphology operators
1254 * Addition Third-level Subtractive Morphology Methods:
1255 EdgeIn, EdgeOut, Edge, TopHat, BottomHat
1256 * Ensuring original kernels passed to morphology are cloned before being
1257 modified for use by specific methods (EG: convolve scale/normalize)
1259 2010-02-03 6.5.9-2 Cristy <quetzlzacatenango@image...>
1260 * display -immutable to display transparent image without a checkboard.

1265 2010-01-24 6.5.9-1 Anthony Thyssen <A.Thyssen@griffith...>
1266 * added use of -precision in 'showkernel' output of -morphology
1267 * correct use of a 'reflected kernel' for 'Convolve' 'Dilate' and
1268 'Distance' Morphology primitives. This does not have a performance hit,
1269 though is only truely applicable when the kernel is asymmetric. Note that
1270 'Erode' does not use a 'reflected' kernel, so that 'Open' and 'Close'
1271 operations work properly. This 'reflected usage is defined by online
1272 morphology lecture notes (Google for "EECE Binary Morphology")
1273 * Added convolve kernel scaling setting "-set option:convolve:scale N"
1274 If undefined morphology convolve does not do any scaling or normalization
1275 of the convolution kernel. A value of 0.0 causes normalization for both
1276 zero and non-zero (added weights) kernel types.

1287 quantum:format=floating-point).
1288 * Transparent images no longer flicker on certain system when using the
1290 * Permit interactive resizing with the display program.
1291 * Support heterogeneous distributed processing, see
1292 http://www.imagemagick.org/script/architecture.php#distributed.

1299 2010-01-04 6.5.9-0 Anthony Thyssen <A.Thyssen@griffith...>
1300 * Added Kernel Generator to generate kernels from user strings, which
1301 allows the generation in many built in kernels for both Convolution
1302 and other Morphological methods. New Kernels currently include..
1303 Convolution: Gaussian, Blur, Comet
1304 Morphological: Rectangle, Square, Diamond, Disk, Plus
1305 Distance: Chebyshev, Manhatten, Knight, Euclidean
1306 And both old and new (rectangular) user defined kernel specifications
1307 including the use of 'nan' to represent elements which are not part
1308 of the kernel definition. List built-in kernel types use "-list kernel"
1309 * Added -morphology {method}[:{iteration}] {kernel_string}
1310 Initial methods includes no only the basic morphology methods: Dilate,
1311 Erode, Open, Close; and a pixel color preserving 'Intensity' version, but
1312 also the special methods: Convolve, and Distance. Of course the
1313 appropriate kernel should be provided for each specific method.
1315 2010-01-01 6.5.9-0 Cristy <quetzlzacatenango@image...>
1316 * Add OpenCL-enabled filter (e.g. convert image.png -process
1317 "convolve '-1, -1, -1, -1, 9, -1, -1, -1, -1'" image.jpg).
1318 * Added StringTo...() processing functions
1320 2009-12-27 6.5.8-9 Anthony Thyssen <A.Thyssen@griffith...>

1585 Including non-overlapping regions bugs found in in operators Divide,
1586 ColorDodge, VividLight. And the handling of transparency to follow
1587 standard 'Over' Blending in Divide. Only math methods not looked at are
1588 the addition methods Plus, Add, Minus, and Subtract, which do not follow

1604 * From the notes on Photoshop blend modes at
1605 http://www.simplefilter.de/en/basics/mixmods.html
1606 Added extra composition modes:
1607 VividLight, PinLight, LinearBurn, LinearDodge
1608 NOTE: 'LinearBurn' the same as 'Plus' but with the normal 'Over' blending.

1612 ColorBurn, ColorDodge, Multiply, Screen to make it more readable, easier
1613 to debug, and directly comparable to SVG specifications.
1614 * Specifications changed for SoftLight, ColorBurn, ColorDodge
1615 Though only SoftLight changed to significantly.
1616 * However implementation errors were found for ColorBurn, LinearLight

1623 prime time just yet.
1624 * Support -cdl (color decision list) option.
1625 * Support breaks in Chinese characters which traditionally do not include
1627 * Don't process directories as filenames when using wildcard paths

1660 * Improve FITS keyword parser.
1662 2009-06-14 6.5.3-7 Anthony Thyssen <A.Thyssen@griffith...>
1663 * Cleanup of compose 'displace' of old useless code that is not used.
1664 * Implement a compose 'distort' mapping method,
1665 This is basically exactly like 'displace' but relative to a fixed point
1666 which may be user supplied as +X+Y
1667 * Default scaling to width/2 and height/2 of overlay (100% scale)
1668 with a distortion 'center' to the middle of the overlay image
1669 * If a '%' flag given scale displacement relative to image size
1670 * If a '!' flag given make scale and center relative to 'background' image
1671 instead of the overlay map.
1672 * If no 'height' scale given, use the X scale.
1674 2009-06-13 6.5.3-6 Anthony Thyssen <A.Thyssen@griffith...>
1675 * Fixed bug for compose methods, Hue, Saturate, Luminize

1684 for correct handling of 2 dimensional -compose "displace".
1685 * Fixed PerlMagick Composite() for the same thing.
1686 * Modified compose "Displace" so displacement image's alpha channel can be
1687 used to mask the transparency of the overlay area.
1689 2009-06-07 6.5.3-4 Cristy <quetzlzacatenango@image...>
1690 * Added the HALD image Color LUT, and a no-op HALD: image generator.
1691 See Introduction at http://www.quelsolaar.com/technology/clut.html
1693 2009-06-07 6.5.3-4 Anthony Thyssen <A.Thyssen@griffith...>
1694 * Changed CompositeImageChannel() so that extra compose arguments are
1695 now passed in the ImageArtifact "compose:args". This can be assigned to
1696 images using -set "option:compose:args" 'args' where args are defined
1697 using 'geometry' style or 'comma separated numbers'.
1698 * Declared the special flag needed for Composite Tiling as the ImageArtifact

1768 2009-05-06 6.5.2-3 Glenn Randers-Pehrson <glennrp@image...>
1769 * Progress on "-define png:bit-depth=value" and "-define png:color-type=value"
1770 It is now able to write an opaque black-and-white image in any of the 15
1771 valid combinations of PNG color-type and bit-depth.
1772 * Fixed a regression with writing sub-8-bit grayscale PNGs.
1774 2009-05-06 6.5.2-2 Chris Madison <madisonblu@gmail...>
1775 * Create 8-bit TIFF images if -depth is set to 8 and HDRI-enable ImageMagick.
1777 2009-05-04 6.5.2-1 Chris Madison <madisonblu@gmail...>
1778 * Accept file lists on the command line (e.g. echo "rose: rose.png" |
1780 * Duplicate line in tiff.c breaking read of zip compressed tif (reference
1781 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=13688).
1782 * Support policies to permit or deny any coder, delegate, filter, or file
1783 path (see policy.xml).
1785 2009-05-02 6.5.2-0 Chris Madison <madisonblu@gmail...>
1786 * The mogrify -crop option returns multiple images if an x/y offset is not

1792 * Accept "-define png:bit-depth=value" and "-define png:color-type=value"
1793 options. This is work-in-progress with the objective of being able to
1794 precisely specify the type of PNG file to be written. The previously-used
1795 internal attribute "png:bit-depth" that was used to communicate between
1796 the PNG writer and the JNG writer is changed to "png:bit-depth-written".
1797 This feature needs testing. It is important to note that this feature
1798 cannot be used to force the PNG to use a bit-depth or color-type that
1799 does not losslessly represent the image. You can, however, cause
1800 the writer to use a larger depth or to use the RGB colorspace when
1801 grayscale or indexed would have been sufficent.
1803 2009-05-01 6.5.1-10 Anthony Thyssen <A.Thyssen@griffith...>
1804 * Fixed the Rmin usage in Depolar and Polar distortions
1805 * The 6th argument (Ato) for Polar/Depolar is now optional and defaults

1837 while writing PNG datastreams.
1839 2009-04-21 6.5.1-4 Glenn Randers-Pehrson <glennrp@image...>
1840 * Sometimes the PNG8: format would produce 1-, 2-, or 4-bit PNG datastreams.
1841 Now it always produces 8-bit datastreams as users probably expect.
1843 2009-04-21 6.5.1-4 Glenn Randers-Pehrson <glennrp@image...>
1844 * Suppressed "shadowed declaration" warnings in coders/jpeg.c and

1977 examples and command-line snippets, which now have a new look: dark blue
1978 boxes with white/yellow text to indicate sample input/output. Inclusion of
1979 current version and release dates in appropriate places are now
1980 automatically generated. Also, many changes have been made to begin to
1981 bring the pages into strict W3C compliance with respect to both HTML and
1984 2009-02-21 6.4.9-7 Chris Madison <madisonblu@gmail...>
1985 * The identify program reads the image pixels when the -format option is

2002 * Support file descriptors (e.g. convert image.jpg fd:3 ...).
2003 * The stream utility no longer go into an infinite loop (reference
2004 http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=13102).

2517 Function maps black and white values to the given level values.
2518 Rather than mapping the given level values to black and white.
2519 Bacically a 'reverse-level' function, with different input args.
2520 * Set +level or a '!' flag in -level or LevelImage() to call
2521 the new 'reverse-level' function LevelizeImageChannels().
2522 * More work on IsMagickColorSimular() to fix relationship between
2523 transparent-black and opaque-black, which was matched as 'simular'.
2524 Also attempts to fix 'K' channel handling for CMYK colorspace.
2525 More work on this to come.
2527 2008-06-25 6.4.1-9 Cristy <quetzlzacatenango@image...>

2661 * Revised png.c to avoid saving unknown chunk types that will never
2662 be used later. This prevents the vulnerability described in
2663 CVE-2008-1382, with respect to all unknown chunks except vpAg.
2664 To handle an invalid, zero-length vpAg chunk properly will require
2665 libpng-1.2.27 or later.

2870 2007-11-03 6.3.6-7 Chris Madison <madisonblu@hotma...>
2871 * MAGICK_ERX_SRCS should be MAGICK_EXR_SRCS in coders/Makefile.am.
2873 2007-11-02 6.3.6-6 Cristy <quetzlzacatenango@image...>
2874 * Upgrade to FPX version libfpx-1.2.0.14 (reference
2875 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=10041).
2876 * Modules are searched first in the directories specified by the environment
2877 variables, and then -- if the desired module is not found -- in the
2878 compiled-in path. (reference
2879 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=10039).

2894 * Further expandsion and handling of filters with expert options.
2895 -filter selects from a table of standard filter settings, while
2896 expert options allow complete selection of filter, windowing, support
2897 and blurring options. Includes automatic switch from Sinc to Bessel
2898 for operators using 2 dimentional cylindrical filter, rather than
2899 two pass 1 dimentional orthogonal filters.
2901 2007-10-14 6.3.6-3 Cristy <quetzlzacatenango@image...>
2902 * Obsolete -support (set filter blur factor)
2903 * Expandsion to add -set/define filter options
2905 2007-10-12 6.3.6-2 Anthony <anthony@griffith...>
2906 * Least Squares coordinate handling added for -distort methods Affine,
2907 Perspective, Bilinear. This allows for more than the minimal number of
2908 coordinates to be used to 'fit' a distortion function to an image.
2909 This addition will allow the use of image registration to generate
2910 panarama overviews and better geographical coordinate correction.
2911 * Cosolidated the simular methods FlattenImage() and MosaicImage()
2912 into a new layers function MergeImageLayers() method, adding 'flatten'
2913 and 'mosaic' layer methods.
2914 * Addition of another simular layers method 'merge' which 'unlocks' the
2915 normal flatten/mosaic layer merger from the origin, The resulting image
2916 will have a virtual canvas of minimal size with an offset. Also images
2917 with negative offsets will not be clipped by the 'merge' form of the
2918 command. This was created for better layering of distorted images, such
2919 as panarama overlays.
2920 * Bug fix in handling transparency for EWA resampling.
2921 * Access to Resize Filter Functions from resize.c (for resample.c)
2922 with posible future filter sources... Acquire/Destory/Call ResizeFilter()
2923 * All resize filters added to resampling, but filter handling is incomplete.
2925 2007-10-05 6.3.6-2 Cristy <quetzlzacatenango@image...>
2926 * The box filter no longer produces a black grid when resizing an image
2928 * Respect cropbox for PDF with a subimage specification (e.g.
2930 * Detect proper PDF bounding box when offsets are negative.
2932 2007-10-02 6.3.6-1 Cristy <quetzlzacatenango@image...>
2933 * Speed up the Fx interpreter.
2934 * Use ULL not ui64 for MinGW 64-bit constants.
2935 * Call SyncCacheView() instead of SyncImagePixels() in WaveImage().
2936 * Close all references to a pixel cache on disk before removing the temporary
2937 file as required under Windows.
2939 2007-09-29 6.3.6-0 Anthony <anthony@griffith...>
2940 * Added Scaling 'derivitives' to -distort Arc, so image arcing is now
2941 sharp and clear as you approach the center of the distort.
2942 * Added " -set option:distort:viewport 'geometry' " special option
2943 that can be used to override the output image size and offset.
2944 * Fixed experimental use of -filter and -support in Resampling (more later).
2945 * Changed order for coordinate arguments in -distort (for later leastsq
2946 multiple coordinate distortion function fitting)
2948 2007-09-22 6.3.6-0 Cristy <quetzlzacatenango@image...>
2949 * Check the API version and quantum depth before loading a coder module or
2950 image filter (reference
2951 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=9780).
2952 * Add exception to the image filter signature.
2953 * Get the execution path under Mac OS X.
2954 * TIFFTAG_STRIPBYTECOUNTS requires a uint32 pointer (magick/compress.c).
2955 * Fixed memory leak in CloneString() (reference
2956 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=9763).
2957 * Set S_IRUSR | S_IWUSR | S_IRGRP mode when writing a file in
2960 2007-09-18 6.3.5-9 Anthony <anthony@griffith...>
2961 * Bug fix for +distort in Perspective, also effected PerspectiveProjection
2963 2007-09-17 6.3.5-10 Cristy <quetzlzacatenango@image...>
2964 * Replace all InterpolatePixelColor() calls to use the ResamplePixelColor()
2966 * Map the display program pan icon window for each oversized image.
2967 * The ufraw delegate does not like quotes around the output filename.
2968 * Adjust the sensitivity of a few PerlMagick tests to pass the validation on
2969 a 64-bit FreeBSD system.
2970 * The -level option now works properly for colormapped images.
2971 * Allow Extrapolated blending of images using -blend
2972 http://netpbm.sourceforge.net/doc/extendedopacity.html
2974 2007-09-12 6.3.5-9 Anthony <anthony@griffith...>
2975 * Major Addition, Area Resampling Functions, (scaled interpolation)
2976 for pixel lookup in Distortion functions. This improves the look in
2977 areas of minification enormousally, especially in situations of infinite
2978 tiling and horizon views. All virtual pixel methods have been handled
2979 to minimise computation time involved with area resampling. To use the
2980 new function distortions need to be able to determine scaling vectors
2981 (distortion function derivitives) for correct working. All
2982 -distort methods, except Arc, uses scaled area resampling.
2983 * Improvements to perspective distort method, to include the correct
2984 differentation between the 'ground' on which the image lies, and the
2985 'sky', the color of which can be set using the -mattecolor setting
2986 (as the distortion invalid pixel color). Background color is retains
2987 for surrounding ground areas. The horizon is also correct anti-aliased
2988 and transparent colors are also allowed, allowing you to add backdrops
2989 of gradients and patterns.

3187 sizes to match the first frame, as well.
3189 2007-04-06 6.3.3-6 Anthony <anthony@griffith...>
3190 * Addition of a CompositeImages() "layer.c" function to compose two
3191 separate image lists together (with a virtual canvas offset) in three
3192 different ways, depending on the size of the lists.
3193 * A 'hack' for command line use (the two lists separates by the special
3194 "NULL" image, which is junked) has also been added. Specifically...
3195 "-layers Composite".
3197 2007-04-04 6.3.3-6 Anthony <anthony@griffith...>
3198 * Add -layers RemoveDups method to remove duplicate sequential images in
