2 * Fixed a rounding/truncation error while writing the pHYs chunk in the
4 * Don't write a text-encoded profile when "-define PNG:exclude-chunk=text"
6 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17086 and
7 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18225).
9 2011-03-14 6.6.8-5 Cristy <quetzlzacatenango@image...>
10 * Add support for the WebP image format.
12 2011-03-14 6.6.8-5 Anthony Thyssen <A.Thyssen@griffith...>
13 * Ensured that -sparse-color preserves unused channels when
14 channel limited. Before this unused channels would be reset to black.
16 2011-03-11 6.6.8-4 Glenn Randers-Pehrson <glennrp@image...>
17 * Don't try to store a bKGD chunk in a PNG8 when there are already
18 256 colors in the palette and the background colors is not in that
20 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18199);
21 * The "-define PNG:exclude-chunk=bKGD" option was also excluding
22 the text chunks. (reference
23 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18253).
25 2011-03-10 6.6.8-4 Cristy <quetzlzacatenango@image...>
26 * Fx is a mathematical function. Do not treat transparency as black.
27 * No image scene suffix for filenames that include a single bracket (reference
28 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18267).
30 2011-03-10 6.6.8-3 Cristy <quetzlzacatenango@image...>
31 * New version 6.6.8-3.
33 2011-03-10 6.6.8-3 Cristy <quetzlzacatenango@image...>
34 * Boost causes an ambiguity with ssize_t when building PythonMagick. Add
35 patch from Arfrever@gento... to fix the build exception.
37 2011-03-09 6.6.8-2 Cristy <quetzlzacatenango@image...>
38 * Support the Radiance HDR image format.
39 * Update the offset in the black channel when sharpening to avoid incorrect
41 * Do not use GenericReadMethod for TIFF images with 64-bits per sample.
43 2011-03-06 6.6.8-2 Glenn Randers-Pehrson <glennrp@image...>
44 * Throw error message when the requested color-type or bit-depth
45 cannot be written by the PNG encoder (error was being thrown
46 into the wrong image structure). (Reference
47 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18162).
48 * Don't write a PNG text chunk with "density" keyword that overrides the
49 PNG pHYs chunk, if the pHYs chunk was not excluded (reference
50 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18253).
51 * Ignore any PNG text chunk with a "density" keyword found by the PNG
52 decoder, if the PNG datastream also contains a pHYs chunk.
54 2011-03-06 6.6.8-1 Cristy <quetzlzacatenango@image...>
55 * New version 6.6.8-1.
57 2011-03-05 6.6.8-1 Cristy <quetzlzacatenango@image...>
58 * Support PSD files with one layer and one composite layer.
59 * We must cast a Quantum type when bit shifting and HDRI is enabled.
61 2011-03-05 6.6.8-0 Cristy <quetzlzacatenango@image...>
62 * New version 6.6.8-0.
64 2011-02-27 6.6.8-0 Cristy <quetzlzacatenango@image...>
65 * Add support for the -mode option.
67 2011-02-27 6.6.8-0 Glenn Randers-Pehrson <glennrp@image...>
68 * Fix scaling of new color-reduction method in the PNG encoder (16-bit
69 images were scaled down to 0 or 1, or nearly black).
70 * Delay opening the PNG output blob until the PNG encoder is ready
71 to write the IHDR chunk, to avoid writing zero-length PNG files when
72 errors are found while building the palette. (reference
73 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18162).
75 2011-02-25 6.6.7-10 Cristy <quetzlzacatenango@image...>
76 * New version 6.6.7-10.
78 2011-02-23 6.6.7-10 Cristy <quetzlzacatenango@image...>
79 * Avoid seg fault in AppendImages() when one image is in the RGB colorspace
80 but the other is in the CMYK colorspace.
81 * Get rid of 'respect_parenthesis defined but not used' warnings (reference
82 http://www.imagemagick.org/discourse-server/viewtopic.php?f=2&t=18173).
84 2011-02-22 6.6.7-10 Glenn Randers-Pehrson <glennrp@image...>
85 * Write sub-8-bit grayscale PNG images as palette-indexed PNG images. This
86 usually makes smaller files anyhow.
87 * Eliminated a number of redundant tests for gray images in the PNG encoder.
88 * Removed now-unused IsMonochromeImage() function from coders/png.c
89 * Scan the colormap instead of all of the pixels, when possible, to
90 determine whether the image received by the PNG encoder is grayscale
92 * Avoid reading from the colormap in coders/png.c when it is NULL (reference
93 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18162).
94 * Add a check whether the PNG "cheap transparency" criteria are met. That
95 is, there is a single transparent color, no semitransparent colors, and
96 no opaque color that has the same RGB components as the transparent
97 color. If those aren't met, a color that is transparent in one pixel
98 and opaque in another would always be rendered as transparent, so we
99 must write a PNG colortype that has an alpha channel (reference
100 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18167).
102 2011-02-22 6.6.7-9 Cristy <quetzlzacatenango@image...>
103 * New version 6.6.7-9.
105 2011-02-22 6.6.7-9 Glenn Randers-Pehrson <glennrp@image...>
106 * Disabled reduction of grayscale images (color-type 0) to less than 8 bits
107 when writing because this sometimes produced incorrect output (reference
108 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18098).
110 2011-02-21 6.6.7-9 Cristy <quetzlzacatenango@image...>
111 * Check image has properties before accessing the splay tree (reference
112 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18136).
114 2011-02-15 6.6.7-8 Cristy <quetzlzacatenango@image...>
115 * New version 6.6.7-8.
117 2011-02-14 6.6.7-8 Glenn Randers-Pehrson <glennrp@image...>
118 * The PNG encoder should ignore bogus q->opacity values when image->matte
119 is MagickFalse (reference
120 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18067).
122 2011-02-14 6.6.7-8 Cristy <quetzlzacatenango@image...>
123 * Use implicit image format when explicit format is bogus (e.g.
124 02.13.11-18:43:58.png now writes as PNG).
125 * Fix problem with 4GB file seeks on a 32-bit OS.
127 2011-02-13 6.6.7-7 Anthony Thyssen <A.Thyssen@griffith...>
128 * Fixed Variable blur to handle small (< 1.0 sigma) blurs generated
129 by the blur map being used, rather than just 'cutoff' suddenly.
131 2011-02-08 6.6.7-7 Cristy <quetzlzacatenango@image...>
132 * Support 16-bit per pixel YUV image files.
133 * Fix off-by-one error in PosterizeImage().
134 * Posterize now distributes color uniformly (reference
135 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17623).
136 * Add -smush option (reference
137 http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=17953).
138 * Repair memory leak in the display program.
140 2011-02-07 6.6.7-6 Cristy <quetzlzacatenango@image...>
141 * Fix bug in carg() define when HAVE_COMPLEX is not defined (reference
142 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18030).
144 2011-02-06 6.6.7-6 Anthony Thyssen <A.Thyssen@griffith...>
145 * Default sigma for Gauusian resize filter is now 1/2 for both
146 orthogonal resize and cylindrical EWA distortions.
148 2011-02-02 6.6.7-5 Cristy <quetzlzacatenango@image...>
149 * Check if the font is null in RenderFreetype() to prevent fault (reference
150 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17890).
151 * Eliminate fault when reading WMF image files (reference
152 http://www.imagemagick.org/discourse-server/viewtopic.php?f=2&t=17971).
153 * Support multi-page transparent Postscript and PDF image files.
154 * The compare fuzz metric now returns the same correct value for
155 'xc:white xc:blue -alpha off' and 'xc:white xc:blue -alpha on'.
157 2011-01-29 6.6.7-4 Paul Heckbert <ph@cs.cm...>
158 * Move coders/tiff.c conditional compile to define TIFF exception /
159 semaphore / key when TIFF delegate is disabled.
161 2011-01-29 6.6.7-4 Glenn Randers-Pehrson <glennrp@image...>
162 * Renamed variables, macros, and functions defined/declared in coders/png.c
163 that were in the libpng namespace (beginning with "png_" or "PNG_").
165 2011-01-25 6.6.7-3 Glenn Randers-Pehrson <glennrp@image...>
166 * Removed a call to GetNumberColors() from the PNG encoder that was
167 only there for debugging purposes and was consuming a huge amount
168 of CPU time. (reference
169 http://www.imagemagick.org/discourse-server/viewtopic.php?f=2&t=17799).
170 * Sometimes black was still written as transparent, when the PNG
171 encoder received an image with image->matte==true but no transparent
172 pixels were present. (reference
173 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17913);
175 2011-01-24 6.6.7-3 Cristy <quetzlzacatenango@image...>
176 * Remove memory leak from ThrowFileException() macro (reference
177 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17908).
178 * Multiple blue error count by 'count' in ClassifyImageColors()
179 * Add support for the AAI image format.
181 2011-01-22 6.6.7-2 Cristy <quetzlzacatenango@image...>
182 * Accept quoted file paths in indirect file references (e.g. @myFiles.txt).
184 2011-01-19 6.6.7-2 Glenn Randers-Pehrson <glennrp@image...>
185 * Changed the PNG encoder's "transparent_color" from a UShortPixelPacket
186 to LongPixelPacket and made the default (65537,65537,65537), which
187 can never occur in the PNG image data. Previously the default was
188 (0,0,0) and black pixels would be rendered as as transparent when
189 no tRNS chunk was present in the input, which has caused problems
190 with some test cases since version 6.6.6-10.
191 * Improved the PNG_BUILD_PALETTE section to count opaque, transparent,
192 and semitransparent pixels separately. Previously it wasn't always
193 possible to determine if there was a single fully-transparent color,
194 to decide whether to write an RGBA or Gray-Alpha image or an RGB or
195 Gray image with a tRNS chunk.
197 2011-01-15 6.6.7-1 Cristy <quetzlzacatenango@image...>
198 * Do not reset image next / previous when detach argument is false for
200 * Inline cropping no longer fails for inline raw images (e.g.
201 -size 640x480 -depth 8 'gray:logo[100x100+200+200]').
203 2011-01-14 6.6.7-1 Glenn Randers-Pehrson <glennrp@image...>
204 * Don't let the PNG encoder try to sort the colormap when there are more
205 than 256 colors in the image. (reference
206 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17834).
208 2011-01-10 6.6.7-1 Cristy <quetzlzacatenango@image...>
209 * Accept escaped % in output filename (reference
210 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17810).
212 2011-01-08 6.6.7-1 Glenn Randers-Pehrson <glennrp@image...>
213 * Quieted some inconsequential warnings in the PNG codec due to a
214 change in the type of the PNG iCCP profile from png_charp to png_bytep
217 2011-01-03 6.6.7-0 Cristy <quetzlzacatenango@image...>
218 * Handle negative heights for ICO images.
220 2011-01-02 6.6.7-0 Glenn Randers-Pehrson <glennrp@image...>
221 * Recent changes sometimes caused the PNG encoder to select colortype=2
222 (Truecolor) instead of 0 (Grayscale) for grayscale images. This made
223 the filesize larger than necessary and caused some of the PerlMagick
226 2011-01-01 6.6.6-10 Glenn Randers-Pehrson <glennrp@image...>
227 * The PNG decoder now checks whether the image actually has any transparency
228 when the input file contains an alpha channel or a tRNS chunk. (Reference
229 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17748)
231 2010-12-26 6.6.6-8 Cristy <quetzlzacatenango@image...>
232 * -posterize fails with more than 40 levels (reference
233 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17741).
234 * Add support for the MacPaint image format.
235 * Eliminate spurious 'invalid colormap index' exception for 16-bit SGI images
236 (bug report by steven.sittser@fligh...).
237 * Fix user data length for the CIN image format.
239 2010-12-21 6.6.6-7 Glenn Randers-Pehrson <glennrp@image...>
240 * Use a clone instead of the main image in coders/png.c, so the image
241 can still be used later on without being affected by changes made by
243 * Added PNG:exclude-chunk and PNG:include-chunk defines.
244 * Revised the -strip option so it behaves as though
245 "-define PNG:include-chunk=none,gama" had appeared on the commandline.
246 * Avoid writing PNG ancillary chunks in the PNG/MNG/JNG encoder while
247 generating the alpha channel for a JNG image.
249 2010-12-21 6.6.6-7 Anthony Thyssen <A.Thyssen@griffith...>
250 * Removed the forced interpolation setting in AcquireResampleFilterThreadSet
251 It prevented user defined interpolation settings for -clut, and possibly
254 2010-12-17 6.6.6-6 Chris Madison <madisonblu@gmail...>
255 * Add LZMA compression support to ImageMagick.
256 * Eliminate seg-fault in MvgPrintf().
258 2010-12-17 6.6.6-6 Glenn Randers-Pehrson <glennrp@image...>
259 * Eliminated a redundant quantization step in the PNG encoder.
260 * Untangled a confusing but apparently harmless improper loop nesting
262 * Eliminated redundant "IsGray()" tests from the PNG encoder.
264 2010-12-14 6.6.6-6 Cristy <quetzlzacatenango@image...>
265 * -format "%[fx:u.p{5,5}]" no longer reports parse exception (reference
266 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17678).
268 2010-12-10 6.6.6-5 Glenn Randers-Pehrson <glennrp@image...>
269 * Make the PNG encoder always rebuild the palette, to avoid losing
270 transparency when it is out of sync with the pixel data (reference
271 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17655).
272 * Eliminated CompressColormapTransFirst() since the palette is already
273 compressed and sorted by opacity now when it's recreated.
275 2010-12-10 6.6.6-5 Cristy <quetzlzacatenango@image...>
276 * Account for virtual canvas for the -flip / -flop options (reference
277 http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=17626).
278 * Also for -transpose and transverse options
279 * Support -metric fuzz option.
281 2010-12-09 6.6.6-4 Anthony Thyssen <A.Thyssen@griffith...>
282 * Replace IsMagickColorSimilar() which provides the Fuzz Factor threshold
283 function. Note function does not calculate 'distance' in total but
284 short-circuits when threshold is reached for faster processing.
285 * Ordered Dithered handling of Alpha channel was incorrect - fixing
286 Bug was introduced v6.6.5-6
288 2010-12-03 6.6.6-3 Glenn Randers-Pehrson <glennrp@image...>
289 * Fixed two more cases where the PNG encoder lost transparency (reference
290 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17516).
292 2010-12-01 6.6.6-2 Cristy <quetzlzacatenango@image...>
293 * Affine multiplication reversed when translating (reference
294 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17570).
296 2010-11-26 6.6.6-2 Glenn Randers-Pehrson <glennrp@image...>
297 * Revised the "c7x7b" and "c7x7w" ordered-dither maps to be complementary
300 2010-11-27 6.6.6-1 Cristy <quetzlzacatenango@image...>
301 * Add support for -evaluate-sequence median.
303 2010-11-26 6.6.6-0 Glenn Randers-Pehrson <glennrp@image...>
304 * Fixed two more cases where the PNG encoder lost transparency (reference
305 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17516).
307 2010-11-23 6.6.6-0 Cristy <quetzlzacatenango@image...>
308 * The policy.xml sets not-to-exceed resource values (e.g. policy memory limit
309 1GB, -limit 2GB exceeds policy maximum so memory limit is 1GB).
310 * Support NCC (normalized cross correlation) compare metric.
312 2010-11-21 6.6.5-10 Cristy <quetzlzacatenango@image...>
313 * Fix PNG coder compile error when HDRI is enabled.
315 2010-11-17 6.6.5-9 Glenn Randers-Pehrson <glennrp@image...>
316 * Many of the problems with the PNG encoder have been fixed (reference
317 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16490).
318 * The "-type Optimize" option is now deprecated. If present, it is treated
319 by the PNG encoder the same as if the type were undefined. Optimization
320 is now always performed. No other formats used the "type Optimize" option.
321 * Merged redundant code into LosslessReduceDepth() function in the PNG codec.
323 2010-11-14 6.6.5-9 Cristy <quetzlzacatenango@image...>
324 * The splice option no longer throws spurious "pixels are not authentic"
326 * Thread the -adaptive-resize option.
327 * Set XBM coder height to height not width.
329 2010-11-14 6.6.5-9 Nicolas Robidoux <nicolas.robidoux@gmai...>
330 * Lanczos2Sharp blur tweaked. New blur = 0.9549963639785485.
332 2010-11-13 6.6.5-9 Nicolas Robidoux <nicolas.robidoux@gmai...>
333 * LanczosSharp blur tweaked to minimize worst case deviation from "perfect
334 preservation of images which only vary horizontally (or vertically)" under
335 no-op. New blur = 0.9812505644269356.
337 2010-11-08 6.6.5-8 Nicolas Robidoux <nicolas.robidoux@gmai...>
338 * Missing logical operator in tiff.c.
340 2010-11-08 6.6.5-8 Cristy <quetzlzacatenango@image...>
341 * Only save TIFF image with 1-bit depth if there is no alpha channel.
342 * Abandon PSD composite if layer is available.
343 * %[fx:mean] is the mean of the default channels (all but opacity) (reference
344 http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=17432).
346 2010-10-29 6.6.5-6 Glenn Randers-Pehrson <glennrp@image...>
347 * Added 5x5, 6x6, and 7x7 ordered-dither level maps.
349 2010-10-30 6.6.5-5 Cristy <quetzlzacatenango@image...>
350 * Do not read configure files in the current directory for the "installed"
351 version of ImageMagick.
352 * Allow numeric characters in the XPM basename (reference
353 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17385).
355 2010-10-29 6.6.5-4 Glenn Randers-Pehrson <glennrp@image...>
356 * Revised PNG palette optimization
357 * Added some debug logging in coders/png.c.
359 2010-10-28 6.6.5-3 Nicolas Robidoux <nicolas.robidoux@gmai...>
360 * More precise blur values for Lanczos2Sharp and LanczosSharp.
361 * Added location of first Mitchell crossing (=8/7) to the filters data
364 2010-10-28 6.6.5-2 Anthony Thyssen <A.Thyssen@griffith...>
365 * Added Lanczos2D* filters now named Lanczos2*
366 * Reorganization of AcquireFilter() to make it work better
368 2010-10-25 6.6.5-1 Nicolas Robidoux <nicolas.robidoux@gmai...>
369 * Clearer EWA filters (LanczosSharp etc) comments.
371 2010-10-25 6.6.5-1 Anthony Thyssen <A.Thyssen@griffith...>
372 * Added LanczosSharp (3-lobe Lanczos with sharpening)
373 * Filter sharpening factors are also always applied regardless of usage.
375 2010-10-24 6.6.5-1 Nicolas Robidoux <nicolas.robidoux@gmai...>
376 * CubicBC filter formulas simplified by constant folding. In
377 particular, P1 coefficient (always zero) removed from coeff.
379 2010-10-22 6.6.5-1 Nicolas Robidoux <nicolas.robidoux@gmai...>
380 * Revert the Robidoux filter to a Keys cubic with C=(108 sqrt 2-29)/398
381 (as already specified in the documentation).
383 2010-10-14 6.6.5-1 Cristy <quetzlzacatenango@image...>
384 * Ignore PS bounding box offsets if -page is set.
385 * Use #pragma omp master for dumping single threaded debugging information
386 (single caused a fault).
387 * Add support for -evaluate exp.
389 2010-10-12 6.6.5-0 Anthony Thyssen <A.Thyssen@griffith...>
390 * Added "filter:sigma" expert setting defining the 'sigma' for the Gaussian
391 filter only. This is similar in action to 'blur' but only for Gaussians,
392 and does not modify the filters support, allowing you to set a very small
393 sigma, without the function 'missing' all pixels.
394 (This will allow future adjustment of Gaussians for variable blur mapping)
396 2010-10-10 6.6.5-0 Cristy <quetzlzacatenango@image...>
397 * Patch for DrawableRotation() and DrawableTranslation() (reference
398 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17246).
399 * The webp format requires the webpconv delegate program (experimental).
401 2010-10-05 6.6.5-0 Anthony Thyssen <A.Thyssen@griffith...>
402 * Replaced "Robidoux" with Cubic 'Keys' filter that is near equivelent to
403 the previous sharped "Lanczos2D" filter. (C=0.31089212245300069)
404 This also is very similer to a Mitchell filter but specifically designed
405 for EWA use and is the new default filter for Distorting Images.
406 * Original sharpened Lanczos2D filter now called "Lanczos2Dsharp"
408 2010-10-08 6.6.4-10 Jerry Gay <jerry.gay@gmail..>
409 * Autodetect file type support in Makefile.PL to prevent test failures
411 2010-10-05 6.6.4-10 Anthony Thyssen <A.Thyssen@griffith...>
412 * Added new filter 'Lanczos2D' a 2-lobe Lanczos as defined by
413 Andreas Gustafsson in his thesis "Interactive Image Warping" (page 24)
414 http://www.gson.org/thesis/warping-thesis.pdf
415 * Added filter "Robidoux" which is a slightly sharpened version of the
416 "Lanczos2D" filter (blur=0.958033808) specifically designed to be less
417 'blurry' for horizontal and vertical lines in no-op distortions.
419 2010-10-05 6.6.4-10 Cristy <quetzlzacatenango@image...>
420 * Add support for "pattern:vertical2" and "pattern:horizontal2".
421 * Add support for "pattern:vertical3" and "pattern:horizontal3".
422 * Properly handle PSD layers with negative offsets.
424 2010-10-03 6.6.4-9 Cristy <quetzlzacatenango@image...>
425 * Fix memory assertion with --enable-embeddable (reference
426 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17201).
427 * Don't permit access to pixels when pinging an image (reference
428 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17194).
430 2010-10-02 6.6.4-9 Anthony Thyssen <A.Thyssen@griffith...>
431 * Added sqrt(2) blurring default for Gaussian Filter if used as
432 a Cylindrical EWA filter. This resulted removing the last aliasing
433 issue that was present in tests for Gaussian EWA resampling. Of course
434 it is still a very blurry filter for default use in EWA.
435 * Adjusted Variable Mapping Blur Composition so user arguments actual
436 relate properly to the sigma of the blur for a maximum mapping value.
437 * Fix horizon anti-alising for output-scaled perspective distortions.
438 * 'Bessel' filter is now offically and more accuritally named 'Jinc'
439 however 'Bessel' while not visible as a filter option can still be used
440 as an internal alias for 'Jinc'.
442 2010-09-28 6.6.4-8 Nicolas Robidoux <nicolas.robidoux@gmai...>
443 * Chantal Racette double checked the bounding parallelogram computation
444 in resample.c (and I tightened the comments).
446 2010-09-28 6.6.4-8 Cristy <quetzlzacatenango@image...>
447 * Temporary files not always deleted (reference
448 http://www.imagemagick.org/discourse-server/viewtopic.php?f=2&t=15960).
450 2010-09-28 6.6.4-8 Anthony Thyssen <A.Thyssen@griffith...>
451 * Bug fix for -filter point distorts (occasional generating black pixels)
453 2010-09-27 6.6.4-8 Nicolas Robidoux <nicolas.robidoux@gmai...>
454 * Simplified the ClampUpAxes code, the use of its outputs, its comments,
455 and credited Craig DeForest for the "clamp singular values" idea.
456 * No reason to have "insane" precision Sinc in resize.c: Use
457 the 1.2e-12 max. abs. relative error version for Q64 as well as Q32.
459 2010-09-27 6.6.4-8 Anthony Thyssen <A.Thyssen@griffith...>
460 * Replace the blurry "High Quality EWA" technique with a 'Clamped EWA'
461 for Distort Resampling. This makes -distort a whole lot nicer
462 and allows for the use of better cylindrical filters.
464 2010-09-26 6.6.4-7 Anthony Thyssen <A.Thyssen@griffith...>
465 * Fix Point filter for ResizeImage() caused by support limiting the
466 Box weighting function.
468 2010-09-26 6.6.4-6 Cristy <quetzlzacatenango@image...>
469 * Don't allow resize filter weights to go to zero (reference
470 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17132).
472 2010-09-24 6.6.4-6 Nicolas Robidoux <nicolas.robidoux@gmai...>
473 * Now that MagickPIL is a MagickRealType, some casts are unneeded.
475 2010-09-21 6.6.4-6 Cristy <quetzlzacatenango@image...>
476 * Do not break words if caption size is absolute (reference
477 http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=17123).
478 * Don't define HAVE_THREADS for --without-threads configure script option.
480 2010-09-20 6.6.4-5 Nicolas Robidoux <nicolas.robidoux@gmai...>
481 * Modified "magick/resize.c" so that MagickPIL is a MagickRealType number.
482 Some computations were needlessly done in long double precision because
483 PIL forced an automatic upcast wherever it appeared. Changed its name to
484 MagickREALTYPEPI. <- This was later reverted back to MagickPIL.
485 * Modified "magick/resize.c" so that Bohman uses one trig call + one sqrt
486 call instead of two trig calls.
488 2010-09-20 6.6.4-5 Anthony Thyssen <A.Thyssen@griffith...>
489 * modified "magick/resample.c" to allow use of either EWA or HQEWA (default)
490 * Removed LanczosFast from supported filters (SincFast*SincFast is faster)
492 2010-09-19 6.6.4-5 Cristy <quetzlzacatenango@image...>
493 * If IPTC profile is not embedded in an 8bim resource, declare it IPTC
495 * Support %[version] and %[copyright].
496 * Improve performance of the pixel cache.
498 2010-09-18 6.6.4-4 Cristy <quetzlzacatenango@image...>
499 * Automatically set the quantum depth to 16 for HDRI.
501 2010-09-16 6.6.4-2 Cristy <quetzlzacatenango@image...>
502 * IPTC profile not always wrapped properly inside an 8BIM profile.
503 * TIFF tile geometry must be divisible by 16.
505 2010-09-15 6.6.4-2 Anthony Thyssen <A.Thyssen@griffith...>
506 * Rename of SincPolynomial to SincFast for easier user understanding
507 * Ditto for LanczosChebyshev to LanzcosFast
509 2010-09-14 6.6.4-2 Anthony Thyssen <A.Thyssen@griffith...>
510 * Switch default resize filters to using the faster SincPolynomial
511 filter by default internally. However 'Sinc' will still use the
512 Trigonometric function, and can be used to assign the trig version
513 of Sinc() to filters using the filter expert options.
514 * The default filter for 'distort' was found to be a very blurry inaccurate
515 filter function. It was removed and replaced with a correct Gaussian
516 filter (as used by resize)
517 * Added a switch so that "-interpolate filter" will force the use of
518 a cylindrical filter for ALL pixels in distorted images. That is you can
519 use that switch to use a cylindrical filter even for images that are
520 being enlarged by the distortion. However EWA is still currently using
521 a fixed 2.0 sampling radius. This switch complements the use of "-filter
522 point" which turns off EWA filters in favor of interpolation for all
523 pixels in a distorted image. BOTH switches should not be used together.
524 * A bug in the support radius of the EWA resampling function was found,
525 now that correctly defined resize filters are being used. Suddenly Normal
526 Gaussian distortions are not so blurry, and tests with distortions of
527 the 'Rings' image show extremely good and clear results, with only minimal
528 blurring. The filter 'blur' expert option can be used to adjust this
531 The above represents a major improvement forward in the quality of the
532 image distortion operator. But near-unity distortions (no scaling) are
535 2010-09-13 6.6.4-2 Cristy <quetzlzacatenango@image...>
536 * Don't negate the geometry offset for the -extent option.
538 2010-09-09 6.6.4-1 Cristy <quetzlzacatenango@image...>
539 * The RGBO format is now listed as a supported format.
541 2010-09-07 6.6.4-1 Anthony Thyssen <A.Thyssen@griffith...>
542 * Added the Nicolas Robidoux and Chantal Racette Lanczos resize filter
543 function as "LanczosChebyshev" as faster alternative to Lanczos.
544 * Re-code Nicolas Robidoux and Chantal Racette Polynomial Approximation of
545 the Sinc Trigonometric resize filter, as a proper filter to allow
546 direct comparision and speed testing of the filter.
547 * Expanded the "-set option:filter:verbose 1" output, so as to also include
548 the actual functions and other values that were used to create the filter.
550 2010-09-02 6.6.4-0 el_supremo <digipete@shaw...>
551 * Repair a few incorrect LocaleNCompare() calls (ttf.c, ps.c).
553 2010-08-31 6.6.4-0 Cristy <quetzlzacatenango@image...>
554 * Path no longer closed if join style is round (reference
555 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16943).
556 * Add case for BGRQuantum to GetQuantumExtent().
557 * Support no compression on PCX write.
559 2010-08-23 6.6.3-10 Cristy <quetzlzacatenango@image...>
560 * Fixed bug in the raw BGRA coders (reference
561 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16880).
562 * Fix off-by-one error in the PSD coders.
563 * Nicolas Robidoux with the assistance of Chantal Racette contribute an
564 approximation of the sinc function over the interval [-3,3].

568 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16958).
570 2010-08-15 6.6.3-7 Cristy <quetzlzacatenango@image...>
571 * Throw exception if image size differs for the compare program but the
572 -subimage-search option is not specified.
574 2010-08-13 6.6.3-6 Cristy <quetzlzacatenango@image...>
575 * The AdobeRgb.tif TIFF image no longer faults under Windows (reference
576 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16838).
577 * Add -subimage-search option to the compare utility.
579 2010-08-12 6.6.3-5 Cristy <quetzlzacatenango@image...>
580 * The -fx 2e+6/1e+5 argument no longer returns the wrong results (reference
581 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16833).
583 2010-08-10 6.6.3-5 Glenn Randers-Pehrson <glennrp@image...>
584 * Emit a warning if the PNG encoder can't satisfy the color type and
585 bit depth requested with a "-define" directive.
587 2010-08-07 6.6.3-4 Cristy <quetzlzacatenango@image...>
588 * The orient option sometimes improperly set "undefined" (reference
589 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16795).
590 * Only list orientation options for the -list orientation option (reference
591 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16801).
592 * Return proper standard deviation for combined channels (reference
593 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16786).
594 * Handle transparency properly for the PSD image format.

603 2010-07-31 6.6.3-2 Cristy <quetzlzacatenango@image...>
604 * Only use the first alpha channel in PSD image.
605 * Only use XPM complying colors for XPM images (e.g. green is rgb(0,255,0)).
607 2010-07-27 6.6.3-2 Glenn Randers-Pehrson <glennrp@image...>
608 * Eliminate useless message about assuming zero delay when writing
609 a single-frame MNG, and changed it from Error to Warning when
610 writing a multiple-frame MNG.
612 2010-07-25 6.6.3-1 Glenn Randers-Pehrson <glennrp@image...>
613 * Don't "ping" a PNG image if it is embedded in a MNG. Otherwise the
614 reader tries to read MNG chunks from the interior of the embedded PNG,
615 resulting in an erroneous "corrupted image" message.
617 2010-07-09 6.6.3-1 Cristy <quetzlzacatenango@image...>
618 * Fix memory leak in for corrupt BMP images (reference
619 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16600).
620 * Repair several issues when writing to stdout (reference
621 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16620).
622 * A GIF image with the .bgr extension is still a GIF (reference
623 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16662).
625 2010-07-07 6.6.3-1 Glenn Randers-Pehrson <glennrp@image...>
626 * The PNG decoder failed to handle the tRNS chunk properly for grayscale
627 images where the PNG bit_depth was not the same as the quantum depth,
628 and the transparent color was not black.
630 2010-07-01 6.6.3-0 Chris Madison <madisonblu@gmail...>
631 * Pinging the DJVU image format no longer faults.
632 * Check for time-limit-exceeded in only one thread.
633 * Reading filenames from a file (e.g. @filenames) no longer includes the
634 utility name (side effect of StringToArgv() method).
636 2010-06-28 6.6.2-10 Cristy <quetzlzacatenango@image...>
637 * Support the tiff:fill-order define.

647 2010-06-22 6.6.2-8 Cristy <quetzlzacatenango@image...>
648 * Skip byte when DDS bitcount is 32 (reference
649 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16487).
650 * Montage now uses final background setting (e.g. montage -background none ...
651 -background lightblue show:).
652 * Do not annotate directory paths in ListFiles().
653 * Reset the image matte for png:color-type=2.
655 2010-06-17 6.6.2-7 Cristy <quetzlzacatenango@image...>
656 * Support new label:pointsize property.
657 * Miscellany->Slide Show, in the display program, now cycles through the
659 * Recognize certain hex color values (e.g. #b9e1cc00) for the -fx argument.
660 * Reduce memory requirements when dithering on the iPhone.
661 * Command line operators no longer affected by settings that appear after
662 them (e.g. -splice 10x0+0+0 -gravity center).
663 * Compute the proper DPX user data field size.

669 * Fix transprancy handling for Morphology Convolve
670 * Adjustments of Hit And Miss and Edge Detection kernel definitions
671 * Added 'ThinDiagonals' Thinning Kernel + two sub-types
672 * Handling for Convolution of 1-D vertical kernels.
673 However this was removed (using #if-#endif) as I found it slower in tests!
675 2010-06-12 6.6.2-5 Cristy <quetzlzacatenango@image...>
676 * mogrify -format properly handles compressed image filename (e.g.
677 -format jpg logo.png.bz2).
678 * Respect +dither option when saving to the GIF image format.
680 2010-06-08 6.6.2-4 Cristy <quetzlzacatenango@image...>
681 * End of string sentinal is \n not \r.

695 2010-06-01 6.6.2-2 Glenn Randers-Pehrson <glennrp@image...>
696 * Properly scale color components of the PNG bKGD chunk.
697 * Prevent MNG divide by zero in calculation of frame_timeout. Set
698 both frame_delay and frame_timeout to infinite when ticks_per_second
699 is zero, as required by the MNG spec.
701 2010-05-31 6.6.2-2 Cristy <quetzlzacatenango@image...>
702 * Add x:silent option to prevent beeps when reading the X image format.
703 * Recognize TTF for GetMagicInfo().

707 * Prevent coders/png.c from attempting to write an empty tRNS chunk.
709 2010-05-25 6.6.2-1 Anthony Thyssen <A.Thyssen@griffith...>
710 * Fix for Square Array Rotates (off center origin rotate)
711 * Added HitAndMiss kernel Ridges2 to find 2 pixel thick ridges
712 * Added FreiChen:0,{angle} FreiChen:{angle} and FreiChen:-1 variations
713 to complete this kernels definition
715 2010-05-24 6.6.2-1 Cristy <quetzlzacatenango@image...>
716 * Respect density when rendering SVG images.
717 * Set AVI handler to the MPEG coder.

721 * Use 64-bit types when compiling with the 64-bit Visual C++ compiler under
723 * Prevent MNG divide by zero in calculation of frame_delay (reference
724 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16320).
726 2010-05-23 6.6.2-0 Anthony Thyssen <A.Thyssen@griffith...>
727 * Third Re-write of MorphologyApply() to better handle compound methods.
728 * Implemented -set option:morphology:compose for merging results of
729 multiple kernels. "None" means re-iterate results with next kernel.
730 While "Undefined" means to use the internal default for a method.
731 Thinning, Thickening, HitAndMiss, Convolve, Correlate defaults to "None"
732 while HitAndMiss defaults to "Lighten" (union of all kernel results).
733 Other morphology methods defaults still to be decided.
734 * Added HitAndMiss Kernel: Ridges (find ridges and pixel width lines)
735 * Rotation Expansion of single kernels '^' and '@' flags in arguments
736 EG: -set option:showkernel 1 -morphology Convolve 'Blur:0x2^'
737 * ExpandKernelInfo() (rotation expand) now groks symmetrical kernels.
738 So the above will only produce a list of 2 kernels, not 4 kernels
740 2010-05-18 6.6.2-0 Anthony Thyssen <A.Thyssen@griffith...>
741 * Separation of internal function MorphologyApply() from
742 MorphologyImageChannel() to calls to convolve without user settings.
743 * Rewrite of MorphologyApply() to output better 'verbose' messages
744 * Better handling of Gaussian tyle filters (bug fixes)
745 * Bug fix and optimization of kernel size calculations in "gem.c"
746 * Allow '^' or '@' flags in 'user defined' kernel size arguments to
747 expand kernel into a rotated list.
748 EG: -set option:showkernel 1 -morphology Thinning '3@: 0,1,0 0,1,0 0,0,0'
749 * Allow a scaled unity kernel to be added to kernel (EdgeDet->Sharpen)
750 EG: -set option:convolve:scale [kernel_scale][^!],[unity_scale][%]
751 * Addition of "Laplacian of Gaussian" (LOG), also known as Mexican Hat
752 EG: -morphology convolve LOG:0x1
753 * Added FreiChen, Kirsch Convolution kernels
754 * Added Descrete 'Laplacian of Gaussian' kernels (Laplacian type 15 and 19)
755 * Added Edges HitAndMiss Kernel
757 2010-05-17 6.6.2-0 Cristy <quetzlzacatenango@image...>
758 * PSD images require a proper layer to support an alpha channel.
759 * Enable PFM endian support.
760 * Add context to -border for montage. Inside the parenthesis it adds a border
761 to the image otherwise it sets the border for the layout manager.
762 * 24-bit BMP images are not colormapped even if header colors != 0.
763 * Set DPX user data like this: -set profile dpx:userdata.txt.
764 * Make sure Lab => RGB => Lab survives the round trip.
766 2010-05-15 6.6.1-10 Cristy <quetzlzacatenango@image...>
767 * Use ScaleCharToQuantum() in coders/src.c (reference
768 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16229).
769 * Don't clamp HDRI EXR pixels.
771 2010-05-14 6.6.1-9 Cristy <quetzlzacatenango@image...>
772 * Increase the estimated # points for the path drawing primitive.
773 * Remove any prior resolution block from PSD before writing the new block.
775 2010-05-14 6.6.1-9 Anthony Thyssen <A.Thyssen@griffith...>
776 * Addition of more Morphological/Convolution Kernels.
777 DOG (Difference of Gaussians) and DOB (Difference of Blurs),
778 EG: -morphology convolve DOG:0x1,3
779 -morphology convolve DOB:0x1,3,90
780 * Added Prewitt, Roberts, Compass Convolution Kernels
781 * Ring Symbol Kernel (subtraction of Disk from a Disk)
783 2010-05-13 6.6.1-9 Cristy <quetzlzacatenango@image...>
784 * The pixel buffer was underallocated for some image formats when streaming.
786 2010-05-12 6.6.1-8 Anthony Thyssen <A.Thyssen@griffith...>
787 * Implementation of Pattern Matching Morphology methods
788 HitAndMiss, Thicken, Thinning
789 * Reporting of Kernel Strings that fail to parse (though not why)
790 * Parsing of Multiple Kernel Strings, generating a list of kernels
791 * Union of results from Multiple Kernels for HitAndMiss method
792 * Interated Multiple Kernels for all other morphology methods
793 * Added many new kernels for HitAndMiss and Convolution
794 Sobel, Laplacian, Cross, Peaks, Corners, LineEnds, LineJunctions,
795 ConvexHull (for Thicken), Skeleton (for Thinning)
797 2010-05-08 6.6.1-8 Glenn Randers-Pehrson <glennrp@image...>
798 * Use proper background.index when writing indexed PNG, if the background
799 color is in the palette.
801 2010-05-08 6.6.1-7 Cristy <quetzlzacatenango@image...>
802 * Fix improper 'invalid colormap index' PNG bug.
803 * Fix PerlMagick compile exception.
805 2010-05-07 6.6.1-6 Anthony Thyssen <A.Thyssen@griffith...>
806 * Added % and ! modification flags to morphology distance kernel
807 scaling factor, for easier usage.
808 * Bug fix for compose math channel handling and morphology diff usage
810 2010-05-06 6.6.1-6 Cristy <quetzlzacatenango@image...>
811 * Do not claim gray colorspace if gray image includes a non-gray pixel.
812 * Initialize BMP alpha channel to opaque for RGB images.
813 * Fixed under allocation for round rectangles.
814 * The -list option returns a 0 status as expected.
816 2010-05-06 6.6.1-6 Anthony Thyssen <A.Thyssen@griffith...>
817 * Made use of new no-'sync' channel enabled mathematical compose methods
818 for the difference morphology methods. These should now work correctly
819 for specific channels, and more importantly for alpha shaped morphology.
821 2010-05-05 6.6.1-6 Glenn Randers-Pehrson <glennrp@image...>
822 * Fixed bugs with losing the opacity channel while writing some PNG images.
823 (bug reported by Anthony T.)
825 2010-05-05 6.6.1-6 Glenn Randers-Pehrson <glennrp@image...>
826 * Simplified and corrected rowbytes calculation in coders/png.c and
829 2010-05-05 6.6.1-6 Anthony Thyssen <A.Thyssen@griffith...>
830 * Rename of "Add" and "Subtract" compositions to "ModulusAdd" and
831 "ModulusSubtract" for more clarity of there functions. Old names
832 will continue to work as expected.
833 * Fix "Minus", "ModulusAdd", and "ModulusSubtract" to follow
834 normal SVG 'Over' blending specifications, (see next for override)
835 Note that this does NOT include the "Plus" composition method which has
836 SVG definition for it to use a 'Plus' blending rather than 'Over' blending.
838 * By default mathematical compositions work as per SVG definition. That is
839 the results are synchronized with 'Over' alpha-blending (except "Plus"
840 which uses 'plus' alpha-blending).
842 By removing the default 'sync' flag from the -channel setting however
843 Break this inter-channel synchronization and do the mathematical operations
844 only on the individual channels as specified by the -channel setting.
845 That is do 'channel' math rather than 'SVG' composition.
847 With this change you can then use mathematical composition methods on
848 individual channels or even with the alpha channel of images.
850 2010-04-28 6.6.1-6 Anthony Thyssen <A.Thyssen@griffith...>
851 * Special case handling in Barrel distortion (pixel at image center)

877 * Support -regard-warnings in the mogrify utility.
878 * Output the correct units for the identify utility (reference
879 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16075).

896 in some channel of the image. In this case no 'stretch is performed, just
899 2010-04-05 6.6.1-1 Cristy <quetzlzacatenango@image...>
900 * WMF support under Windows does not produce the same results as under

929 2010-03-21 6.6.0-9 Cristy <quetzlzacatenango@image...>
930 * Windows does not support complex.h (reference

995 2010-02-16 6.5.9-7 Cristy <quetzlzacatenango@image...>
996 * TransformImage() resets the image blob when called in the PICT decoder;
997 use SetImageExtent() instead.
999 2010-02-14 6.5.9-6 Cristy <quetzlzacatenango@image...>
1000 * Support PSD RLE compression.
1002 2010-02-13 6.5.9-5 Cristy <quetzlzacatenango@image...>
1003 * The jpeg:extent define sometimes exceeded the specified limit.
1005 2010-02-09 6.5.9-4 Cristy <quetzlzacatenango@image...>
1006 * Resolve "too many open files" (reference
1007 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=15546).
1009 2010-02-08 6.5.9-3 Anthony Thyssen <A.Thyssen@griffith...>
1010 * Added Correlate method which does a Convolve without reflecting the kernel.
1012 2010-02-07 6.5.9-3 Cristy <quetzlzacatenango@image...>
1013 * Initialize grayscale colormap for PSD images.
1015 2010-02-07 6.5.9-3 Anthony Thyssen <A.Thyssen@griffith...>

1019 * Ensuring original kernels passed to morphology are cloned before being
1020 modified for use by specific methods (EG: convolve scale/normalize)
1022 2010-02-03 6.5.9-2 Cristy <quetzlzacatenango@image...>

1028 2010-01-24 6.5.9-1 Anthony Thyssen <A.Thyssen@griffith...>
1029 * added use of -precision in 'showkernel' output of -morphology
1030 * correct use of a 'reflected kernel' for 'Convolve' 'Dilate' and
1031 'Distance' Morphology primatives. This does not have a performance hit,
1032 though is only truely applicable when the kernel is asymmetric. Note that
1033 'Erode' does not use a 'reflected' kernel, so that 'Open' and 'Close'
1034 operations work properly. This 'reflected usage is defined by online
1035 morphology lecture notes (Google for "EECE Binary Morphology")
1036 * Added convolve kernel scaling setting "-set option:convolve:scale N"
1037 If undefined morphology convolve does not do any scaling or normalization
1038 of the convolution kernel. A value of 0.0 causes normalization for both
1039 zero and non-zero (added weights) kernel types.

1060 * Add support for the BGRA raw image format.
1062 2010-01-04 6.5.9-0 Anthony Thyssen <A.Thyssen@griffith...>
1063 * Added Kernel Generator to generate kernels from user strings, which
1064 allows the generation in many built in kernels for both Convolution
1065 and other Morphological methods. New Kernels currently include..
1066 Convolution: Gaussian, Blur, Comet
1067 Morphological: Rectangle, Square, Diamond, Disk, Plus
1068 Distance: Chebyshev, Manhatten, Knight, Euclidean
1069 And both old and new (rectangular) user defined kernel specifications
1070 including the use of 'nan' to represent elements which are not part
1071 of the kernel definition. List built-in kernel types use "-list kernel"
1072 * Added -morphology {method}[:{iteration}] {kernel_string}
1073 Initial methods includes no only the basic morphology methods: Dilate,
1074 Erode, Open, Close; and a pixel color preserving 'Intensity' version, but
1075 also the special methods: Convolve, and Distance. Of course the
1076 appropriate kernel should be provided for each specific method.
1078 2010-01-01 6.5.9-0 Cristy <quetzlzacatenango@image...>
1079 * Add OpenCL-enabled filter (e.g. convert image.png -process
1080 "convolve '-1, -1, -1, -1, 9, -1, -1, -1, -1'" image.jpg).
1081 * Added StringTo...() processing functions
1083 2009-12-27 6.5.8-9 Anthony Thyssen <A.Thyssen@griffith...>
1084 * Added MxN tile cropping with overlapping and space handling.

1343 http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=14252).
1344 * Don't use JPEG's color reduction algorithm for less than 8 colors.
1346 2009-07-13 6.5.4-3 Anthony Thyssen <A.Thyssen@griffith...>
1347 * Final testing and bug fixes for all mathematical compose methods
1348 Including non-overlapping regions bugs found in in operators Divide,
1349 ColorDodge, VividLight. And the handling of transparency to follow
1350 standard 'Over' Blending in Divide. Only math methods not looked at are
1351 the addition methods Plus, Add, Minus, and Subtract, which do not follow
1352 normal 'Over' alpha blending behaviour, for the purposes of mask handling.
1354 2009-07-12 6.5.4-3 Anthony Thyssen <A.Thyssen@griffith...>
1355 * Addition of user definable 'Mathematics' compose method
1356 -compose Mathematics -set option:compose:args A,B,C,D -composite
1357 Will implement the formula f(Sc,Dc) = A*Sc*Dc + B*Sc + C*Dc + D
1358 this lets you implement most smooth polynomial compose methods.

1368 http://www.simplefilter.de/en/basics/mixmods.html
1369 Added extra composition modes:
1370 VividLight, PinLight, LinearBurn, LinearDodge
1371 NOTE: 'LinearBurn' the same as 'Plus' but with the normal 'Over' blending.
1373 2009-07-10 6.5.4-3 Anthony Thyssen <A.Thyssen@griffith...>
1374 * Re-coding of Composite methods HardLight, SoftLight, Overlay, LinearLight,
1375 ColorBurn, ColorDodge, Multiply, Screen to make it more readable, easier
1376 to debug, and directly comparable to SVG specifications.
1377 * Specifications changed for SoftLight, ColorBurn, ColorDodge
1378 Though only SoftLight changed to significantly.
1379 * However implementation errors were found for ColorBurn, LinearLight

1399 * DPX user bits are no longer truncated.
1400 * Return image colorspace for -format [%colorspace] option.
1401 * ThumbnailImage(): don't subsample if image is already thumbnail size.
1403 2009-06-23 6.5.4-0 Anthony Thyssen <A.Thyssen@griffith...>
1404 * Automatic determination of B from C and C from B for a 'Keys Filter'
1405 when using the B,C Cubic Filter Expert options was broken.
1406 See http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=14037
1408 2009-06-19 6.5.4-0 Anthony Thyssen <A.Thyssen@griffith...>

1423 * Improve FITS keyword parser.
1425 2009-06-14 6.5.3-7 Anthony Thyssen <A.Thyssen@griffith...>
1426 * Cleanup of compose 'displace' of old useless code that is not used.
1427 * Implement a compose 'distort' mapping method,
1428 This is basically exactly like 'displace' but relative to a fixed point
1429 which may be user supplied as +X+Y
1430 * Default scaling to width/2 and height/2 of overlay (100% scale)
1431 with a distortion 'center' to the middle of the overlay image
1432 * If a '%' flag given scale displacement relative to image size
1433 * If a '!' flag given make scale and center relative to 'background' image
1434 instead of the overlay map.
1435 * If no 'height' scale given, use the X scale.
1437 2009-06-13 6.5.3-6 Anthony Thyssen <A.Thyssen@griffith...>
1438 * Fixed bug for compose methods, Hue, Saturate, Luminize

1445 2009-06-11 6.5.3-5 Anthony Thyssen <A.Thyssen@griffith...>
1446 * Fixed "convert" to merge the third 'mask' image into the 'source' image
1447 for correct handling of 2 dimensional -compose "displace".
1448 * Fixed PerlMagick Composite() for the same thing.
1449 * Modified compose "Displace" so displacement image's alpha channel can be
1450 used to mask the transparency of the overlay area.
1452 2009-06-07 6.5.3-4 Cristy <quetzlzacatenango@image...>
1453 * Added the HALD image Color LUT, and a no-op HALD: image generator.
1454 See Introduction at http://www.quelsolaar.com/technology/clut.html
1456 2009-06-07 6.5.3-4 Anthony Thyssen <A.Thyssen@griffith...>
1457 * Changed CompositeImageChannel() so that extra compose arguments are
1458 now passed in the ImageArtifact "compose:args". This can be assigned to
1459 images using -set "option:compose:args" 'args' where args are defined
1460 using 'geometry' style or 'comma separated numbers'.
1461 * Declared the special flag needed for Composite Tiling as the ImageArtifact
1462 "compose:outside-overlay".
1463 * Documentation update for CompositeImageChannel() in Core Library to
1464 reflect these changes.
1465 * Documentation update for DistortImage() in Core Library with the extra
1466 ImageArtifact controls it can use.

1485 2009-05-29 6.5.3-0 Cristy <quetzlzacatenango@image...>
1486 * Do not treat -page as a global option (reference
1487 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=13864).

1515 2009-05-14 6.5.2-5 Glenn Randers-Pehrson <glennrp@image...>
1516 * Updated help output and command-line options documentation to bring
1517 the -alpha options up to date with what's actually in the code.
1519 2009-05-13 6.5.2-5 Glenn Randers-Pehrson <glennrp@image...>
1520 * Change "depreciated" to "deprecated" in several files.

1528 2009-05-08 6.5.2-4 Cristy <quetzlzacatenango@image...>
1529 * Combined layer of transparent PSD image was not being read properly.
1531 2009-05-06 6.5.2-3 Glenn Randers-Pehrson <glennrp@image...>
1532 * Progress on "-define png:bit-depth=value" and "-define png:color-type=value"
1533 It is now able to write an opaque black-and-white image in any of the 15
1534 valid combinations of PNG color-type and bit-depth.
1535 * Fixed a regression with writing sub-8-bit grayscale PNGs.
1537 2009-05-06 6.5.2-2 Chris Madison <madisonblu@gmail...>
1538 * Create 8-bit TIFF images if -depth is set to 8 and HDRI-enable ImageMagick.
1540 2009-05-04 6.5.2-1 Chris Madison <madisonblu@gmail...>
1541 * Accept file lists on the command line (e.g. echo "rose: rose.png" |
1543 * Duplicate line in tiff.c breaking read of zip compressed tif (reference
1544 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=13688).
1545 * Support policies to permit or deny any coder, delegate, filter, or file
1546 path (see policy.xml).
1548 2009-05-02 6.5.2-0 Chris Madison <madisonblu@gmail...>
1549 * The mogrify -crop option returns multiple images if an x/y offset is not
1550 specified (e.g. -crop 100x100).
1551 * Generate a proper file path for -path @filelist.txt (reference
1552 http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=13671).
1554 2009-05-01 6.5.2-0 Glenn Randers-Pehrson <glennrp@image...>
1555 * Accept "-define png:bit-depth=value" and "-define png:color-type=value"
1556 options. This is work-in-progress with the objective of being able to
1557 precisely specify the type of PNG file to be written. The previously-used
1558 internal attribute "png:bit-depth" that was used to communicate between
1559 the PNG writer and the JNG writer is changed to "png:bit-depth-written".
1560 This feature needs testing. It is important to note that this feature
1561 cannot be used to force the PNG to use a bit-depth or color-type that
1562 does not losslessly represent the image. You can, however, cause
1563 the writer to use a larger depth or to use the RGB colorspace when
1564 grayscale or indexed would have been sufficent.
1566 2009-05-01 6.5.1-10 Anthony Thyssen <A.Thyssen@griffith...>
1567 * Fixed the Rmin usage in Depolar and Polar distortions
1568 * The 6th argument (Ato) for Polar/Depolar is now optional and defaults
1569 to Afrom + 360 degrees (or a fill circle from the given start angle)
1571 2009-04-30 6.5.1-10 Cristy <quetzlzacatenango@image...>
1572 * Do not return a black image for -channel RGBA -gaussian (reference
1573 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=13669).
1575 2009-04-28 6.5.1-9 Cristy <quetzlzacatenango@image...>

1580 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=13633).
1582 2009-04-24 6.5.1-7 Cristy <quetzlzacatenango@image...>
1583 * Grok 'image.psd[0]' and 'image.mpg[0]' (reference
1584 http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=13609).
1585 * Normalize similarity based on reconstruction not the original (reference
1586 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=13626).
1587 * Support multiple JPEG images encapsulated within DICOM.
1589 2009-04-23 6.5.1-6 Cristy <quetzlzacatenango@image...>
1590 * Msys does not understand NAME_MAX.

1595 2009-04-21 6.5.1-4 Glenn Randers-Pehrson <glennrp@image...>
1596 * Check error return from CompressColormapTransFirst() in coders/png.c
1598 2009-04-21 6.5.1-4 Glenn Randers-Pehrson <glennrp@image...>
1599 * Refrain from modifying image struct members (color, depth, matte)
1600 while writing PNG datastreams.
1602 2009-04-21 6.5.1-4 Glenn Randers-Pehrson <glennrp@image...>
1603 * Sometimes the PNG8: format would produce 1-, 2-, or 4-bit PNG datastreams.
1604 Now it always produces 8-bit datastreams as users probably expect.
1606 2009-04-21 6.5.1-4 Glenn Randers-Pehrson <glennrp@image...>
1607 * Suppressed "shadowed declaration" warnings in coders/jpeg.c and
1608 coders/png.c that are triggered by "-Wshadow" gcc compiler flag.

1621 2009-04-11 6.5.1-2 Cristy <quetzlzacatenango@image...>
1622 * Image not properly placed when displaying to the X server root (reference
1623 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=13532).
1624 * fmax() is not support on some platforms (reference
1625 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=13533).
1627 2009-04-11 6.5.1-2 Anthony Thyssen <A.Thyssen@griffith...>

2518 reflected in Magick-config and ImageMagick.pc pkg-config files):
2519 /usr/local/include => /usr/local/include/ImageMagick
2520 libMagick => libMagickCore

2527 * Liquid rescale limits the final size to twice the original size (reference
2528 http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=10536).
2529 * Read EXIF data in TIFF images; writing is pending until we can figure out
2530 how to use the libtiff delegate library to write EXIF data.
2532 2008-01-24 6.3.8-2 Cristy <quetzlzacatenango@image...>
2533 * Add support for liquid rescaling (e.g. -liquid-rescale).
2534 * Support a ^ meta character in an image geometry (.e.g
2535 convert 640x480.png -resize 240^ returns a 320x240 result).
2537 2008-01-20 6.3.8-1 Cristy <quetzlzacatenango@image...>
2538 * Fix transient bug where "identify -format '%w;%[exif:Model]'" failed to

2547 returned Log colorspace).
2548 * Fix -g option for PCL6 support (reference
2549 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=10462).
2551 2008-01-08 6.3.7-10 Cristy <quetzlzacatenango@image...>
2552 * Only read ICON alpha mask if BPP is <= 16.
2553 * Add support for +opaque and +transparent (requested by Anthony).

2559 files (i.e. convert ai:image.ai image.png).
2560 * Set RSVG base URI (patch provided by tsdineen).
2562 2007-12-20 6.3.7-7 Cristy <quetzlzacatenango@image...>
2563 * `Magick-config --version` returns Q16 instead of
2564 Q@MAGICKCORE_QUANTUM_DEPTH@.
2565 * Permit commas in numbers in certain locales (e.g. german +100,000).
2567 2007-12-13 6.3.7-5 Cristy <quetzlzacatenango@image...>
2568 * Added an exception reason to BlobToImage() in the event an image has no
2569 magic number and neither the image magick or filename is set.
2570 * Do not pass PhotoYCC data thru gamma-corrected lookup-table.
2571 * Fix bug in GetEXIFProperty() (reference

2626 (contributed by Sean Burke).
2628 2007-11-04 6.3.6-8 Chris Madison <madisonblu@hotma...>
2629 * Remove ctrl-M characters on in various source files.
2630 * Fix signature for Magick++ averageImages() regression tests for HDRI.
2631 * Only invoke PerlMagick x11 regression test if DISPLAY variable is set.
2633 2007-11-03 6.3.6-7 Chris Madison <madisonblu@hotma...>
2634 * MAGICK_ERX_SRCS should be MAGICK_EXR_SRCS in coders/Makefile.am.
2636 2007-11-02 6.3.6-6 Cristy <quetzlzacatenango@image...>
2637 * Upgrade to FPX version libfpx-1.2.0.14 (reference
2638 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=10041).
2639 * Modules are searched first in the directories specified by the environment
2640 variables, and then -- if the desired module is not found -- in the
2641 compiled-in path. (reference
2642 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=10039).
2644 2007-11-01 6.3.6-5 Cristy <quetzlzacatenango@image...>
2645 * Update FPX regression test reference images.
2646 * Fixed Magick++ compile error for Sun Studio 10 compiler.

2654 * 'verbose' filter plotting output using -define "filter:verbose"
2656 2007-10-20 6.3.6-3 Anthony <anthony@griffith...>
2657 * Further expandsion and handling of filters with expert options.
2658 -filter selects from a table of standard filter settings, while
2659 expert options allow complete selection of filter, windowing, support
2660 and blurring options. Includes automatic switch from Sinc to Bessel
2661 for operators using 2 dimentional cylindrical filter, rather than
2662 two pass 1 dimentional orthogonal filters.
2664 2007-10-14 6.3.6-3 Cristy <quetzlzacatenango@image...>
2665 * Obsolete -support (set filter blur factor)
2666 * Expandsion to add -set/define filter options
2668 2007-10-12 6.3.6-2 Anthony <anthony@griffith...>
2669 * Least Squares coordinate handling added for -distort methods Affine,
2670 Perspective, Bilinear. This allows for more than the minimal number of
2671 coordinates to be used to 'fit' a distortion function to an image.
2672 This addition will allow the use of image registration to generate
2673 panarama overviews and better geographical coordinate correction.
2674 * Cosolidated the simular methods FlattenImage() and MosaicImage()
2675 into a new layers function MergeImageLayers() method, adding 'flatten'
2676 and 'mosaic' layer methods.
2677 * Addition of another simular layers method 'merge' which 'unlocks' the
2678 normal flatten/mosaic layer merger from the origin, The resulting image
2679 will have a virtual canvas of minimal size with an offset. Also images
2680 with negative offsets will not be clipped by the 'merge' form of the
2681 command. This was created for better layering of distorted images, such
2682 as panarama overlays.
2683 * Bug fix in handling transparency for EWA resampling.
2684 * Access to Resize Filter Functions from resize.c (for resample.c)
2685 with posible future filter sources... Acquire/Destory/Call ResizeFilter()
2686 * All resize filters added to resampling, but filter handling is incomplete.
2688 2007-10-05 6.3.6-2 Cristy <quetzlzacatenango@image...>
2689 * The box filter no longer produces a black grid when resizing an image
2691 * Respect cropbox for PDF with a subimage specification (e.g.
2693 * Detect proper PDF bounding box when offsets are negative.
2695 2007-10-02 6.3.6-1 Cristy <quetzlzacatenango@image...>
2696 * Speed up the Fx interpreter.
2697 * Use ULL not ui64 for MinGW 64-bit constants.
2698 * Call SyncCacheView() instead of SyncImagePixels() in WaveImage().
2699 * Close all references to a pixel cache on disk before removing the temporary
2700 file as required under Windows.
2702 2007-09-29 6.3.6-0 Anthony <anthony@griffith...>
2703 * Added Scaling 'derivitives' to -distort Arc, so image arcing is now
2704 sharp and clear as you approach the center of the distort.
2705 * Added " -set option:distort:viewport 'geometry' " special option
2706 that can be used to override the output image size and offset.
2707 * Fixed experimental use of -filter and -support in Resampling (more later).
2708 * Changed order for coordinate arguments in -distort (for later leastsq
2709 multiple coordinate distortion function fitting)
2711 2007-09-22 6.3.6-0 Cristy <quetzlzacatenango@image...>
2712 * Check the API version and quantum depth before loading a coder module or
2713 image filter (reference
2714 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=9780).
2715 * Add exception to the image filter signature.
2716 * Get the execution path under Mac OS X.
2717 * TIFFTAG_STRIPBYTECOUNTS requires a uint32 pointer (magick/compress.c).
2718 * Fixed memory leak in CloneString() (reference
2719 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=9763).
2720 * Set S_IRUSR | S_IWUSR | S_IRGRP mode when writing a file in
2723 2007-09-18 6.3.5-9 Anthony <anthony@griffith...>
2724 * Bug fix for +distort in Perspective, also effected PerspectiveProjection
2726 2007-09-17 6.3.5-10 Cristy <quetzlzacatenango@image...>
2727 * Replace all InterpolatePixelColor() calls to use the ResamplePixelColor()
2729 * Map the display program pan icon window for each oversized image.
2730 * The ufraw delegate does not like quotes around the output filename.
2731 * Adjust the sensitivity of a few PerlMagick tests to pass the validation on
2732 a 64-bit FreeBSD system.
2733 * The -level option now works properly for colormapped images.
2734 * Allow Extrapolated blending of images using -blend
2735 http://netpbm.sourceforge.net/doc/extendedopacity.html
2737 2007-09-12 6.3.5-9 Anthony <anthony@griffith...>
2738 * Major Addition, Area Resampling Functions, (scaled interpolation)
2739 for pixel lookup in Distortion functions. This improves the look in
2740 areas of minification enormousally, especially in situations of infinite
2741 tiling and horizon views. All virtual pixel methods have been handled
2742 to minimise computation time involved with area resampling. To use the
2743 new function distortions need to be able to determine scaling vectors
2744 (distortion function derivitives) for correct working. All
2745 -distort methods, except Arc, uses scaled area resampling.
2746 * Improvements to perspective distort method, to include the correct
2747 differentation between the 'ground' on which the image lies, and the
2748 'sky', the color of which can be set using the -mattecolor setting
2749 (as the distortion invalid pixel color). Background color is retains
2750 for surrounding ground areas. The horizon is also correct anti-aliased
2751 and transparent colors are also allowed, allowing you to add backdrops
2752 of gradients and patterns.

2795 2007-08-07 6.3.5-6 Anthony <anthony@griffith...>
2796 * Enabled use of +distort to auto resize destination image to 'bestfit'
2797 the distorted input image. This also enabled the use of virtual canvas
2798 offsets in source and destination images for most distortion methods.
2800 2007-08-05 6.3.5-6 Cristy <quetzlzacatenango@image...>
2801 * Remove atexit in Magick++ code to avoid possible client crash (reference

2809 size and offset to be set according to the specific distortion being
2812 2007-07-29 6.3.5-5 Cristy <quetzlzacatenango@image...>
2813 * Set the -poloroid border color with the -bordercolor option.
2815 2007-07-25 6.3.5-4 Cristy <quetzlzacatenango@image...>
2816 * Remove extranous break statement so -type option properly sets the
