1 2011-02-27 6.6.8-0 Glenn Randers-Pehrson <glennrp@image...>
2 * Fix scaling of new color-reduction method in the PNG encoder (16-bit
3 images were scaled down to 0 or 1, or nearly black).
4 * Delay opening the PNG output blob until the PNG encoder is ready
5 to write the IHDR chunk, to avoid writing zero-length PNG files when
6 errors are found while building the palette. (reference
7 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18162).
9 2011-02-25 6.6.7-10 Cristy <quetzlzacatenango@image...>
10 * New version 6.6.7-10.
12 2011-02-23 6.6.7-10 Cristy <quetzlzacatenango@image...>
13 * Avoid seg fault in AppendImages() when one image is in the RGB colorspace
14 but the other is in the CMYK colorspace.
15 * Get rid of 'respect_parenthesis defined but not used' warnings (reference
16 http://www.imagemagick.org/discourse-server/viewtopic.php?f=2&t=18173).
18 2011-02-22 6.6.7-10 Glenn Randers-Pehrson <glennrp@image...>
19 * Write sub-8-bit grayscale PNG images as palette-indexed PNG images. This
20 usually makes smaller files anyhow.
21 * Eliminated a number of redundant tests for gray images in the PNG encoder.
22 * Removed now-unused IsMonochromeImage() function from coders/png.c
23 * Scan the colormap instead of all of the pixels, when possible, to
24 determine whether the image received by the PNG encoder is grayscale
26 * Avoid reading from the colormap in coders/png.c when it is NULL (reference
27 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18162).
28 * Add a check whether the PNG "cheap transparency" criteria are met. That
29 is, there is a single transparent color, no semitransparent colors, and
30 no opaque color that has the same RGB components as the transparent
31 color. If those aren't met, a color that is transparent in one pixel
32 and opaque in another would always be rendered as transparent (reference
33 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18167).
35 2011-02-22 6.6.7-9 Cristy <quetzlzacatenango@image...>
36 * New version 6.6.7-9.
38 2011-02-22 6.6.7-9 Glenn Randers-Pehrson <glennrp@image...>
39 * Disabled reduction of grayscale images (color-type 0) to less than 8 bits
40 when writing because this sometimes produced incorrect output (reference
41 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18098).
43 2011-02-21 6.6.7-9 Cristy <quetzlzacatenango@image...>
44 * Check image has properties before accessing the splay tree (reference
45 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18136).
47 2011-02-15 6.6.7-8 Cristy <quetzlzacatenango@image...>
48 * New version 6.6.7-8.
50 2011-02-14 6.6.7-8 Glenn Randers-Pehrson <glennrp@image...>
51 * The PNG encoder should ignore bogus q->opacity values when image->matte
52 is MagickFalse (reference
53 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18067).
55 2011-02-14 6.6.7-8 Cristy <quetzlzacatenango@image...>
56 * Use implicit image format when explicit format is bogus (e.g.
57 02.13.11-18:43:58.png now writes as PNG).
58 * Fix problem with 4GB file seeks on a 32-bit OS.
60 2011-02-13 6.6.7-7 Anthony Thyssen <A.Thyssen@griffith...>
61 * Fixed Variable blur to handle small (< 1.0 sigma) blurs generated
62 by the blur map being used, rather than just 'cutoff' suddenly.
64 2011-02-08 6.6.7-7 Cristy <quetzlzacatenango@image...>
65 * Support 16-bit per pixel YUV image files.
66 * Fix off-by-one error in PosterizeImage().
67 * Posterize now distributes color uniformly (reference
68 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17623).
69 * Add -smush option (reference
70 http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=17953).
71 * Repair memory leak in the display program.
73 2011-02-07 6.6.7-6 Cristy <quetzlzacatenango@image...>
74 * Fix bug in carg() define when HAVE_COMPLEX is not defined (reference
75 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18030).
77 2011-02-06 6.6.7-6 Anthony Thyssen <A.Thyssen@griffith...>
78 * Default sigma for Gauusian resize filter is now 1/2 for both
79 orthogonal resize and cylindrical EWA distortions.
81 2011-02-02 6.6.7-5 Cristy <quetzlzacatenango@image...>
82 * Check if the font is null in RenderFreetype() to prevent fault (reference
83 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17890).
84 * Eliminate fault when reading WMF image files (reference
85 http://www.imagemagick.org/discourse-server/viewtopic.php?f=2&t=17971).
86 * Support multi-page transparent Postscript and PDF image files.
87 * The compare fuzz metric now returns the same correct value for
88 'xc:white xc:blue -alpha off' and 'xc:white xc:blue -alpha on'.
90 2011-01-29 6.6.7-4 Paul Heckbert <ph@cs.cm...>
91 * Move coders/tiff.c conditional compile to define TIFF exception /
92 semaphore / key when TIFF delegate is disabled.
94 2011-01-29 6.6.7-4 Glenn Randers-Pehrson <glennrp@image...>
95 * Renamed variables, macros, and functions defined/declared in coders/png.c
96 that were in the libpng namespace (beginning with "png_" or "PNG_").
98 2011-01-25 6.6.7-3 Glenn Randers-Pehrson <glennrp@image...>
99 * Removed a call to GetNumberColors() from the PNG encoder that was
100 only there for debugging purposes and was consuming a huge amount
101 of CPU time. (reference
102 http://www.imagemagick.org/discourse-server/viewtopic.php?f=2&t=17799).
103 * Sometimes black was still written as transparent, when the PNG
104 encoder received an image with image->matte==true but no transparent
105 pixels were present. (reference
106 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17913);
108 2011-01-24 6.6.7-3 Cristy <quetzlzacatenango@image...>
109 * Remove memory leak from ThrowFileException() macro (reference
110 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17908).
111 * Multiple blue error count by 'count' in ClassifyImageColors()
112 * Add support for the AAI image format.
114 2011-01-22 6.6.7-2 Cristy <quetzlzacatenango@image...>
115 * Accept quoted file paths in indirect file references (e.g. @myFiles.txt).
117 2011-01-19 6.6.7-2 Glenn Randers-Pehrson <glennrp@image...>
118 * Changed the PNG encoder's "transparent_color" from a UShortPixelPacket
119 to LongPixelPacket and made the default (65537,65537,65537), which
120 can never occur in the PNG image data. Previously the default was
121 (0,0,0) and black pixels would be rendered as as transparent when
122 no tRNS chunk was present in the input, which has caused problems
123 with some test cases since version 6.6.6-10.
124 * Improved the PNG_BUILD_PALETTE section to count opaque, transparent,
125 and semitransparent pixels separately. Previously it wasn't always
126 possible to determine if there was a single fully-transparent color,
127 to decide whether to write an RGBA or Gray-Alpha image or an RGB or
128 Gray image with a tRNS chunk.
130 2011-01-15 6.6.7-1 Cristy <quetzlzacatenango@image...>
131 * Do not reset image next / previous when detach argument is false for
133 * Inline cropping no longer fails for inline raw images (e.g.
134 -size 640x480 -depth 8 'gray:logo[100x100+200+200]').
136 2011-01-14 6.6.7-1 Glenn Randers-Pehrson <glennrp@image...>
137 * Don't let the PNG encoder try to sort the colormap when there are more
138 than 256 colors in the image. (reference
139 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17834).
141 2011-01-10 6.6.7-1 Cristy <quetzlzacatenango@image...>
142 * Accept escaped % in output filename (reference
143 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17810).
145 2011-01-08 6.6.7-1 Glenn Randers-Pehrson <glennrp@image...>
146 * Quieted some inconsequential warnings in the PNG codec due to a
147 change in the type of the PNG iCCP profile from png_charp to png_bytep
150 2011-01-03 6.6.7-0 Cristy <quetzlzacatenango@image...>
151 * Handle negative heights for ICO images.
153 2011-01-02 6.6.7-0 Glenn Randers-Pehrson <glennrp@image...>
154 * Recent changes sometimes caused the PNG encoder to select colortype=2
155 (Truecolor) instead of 0 (Grayscale) for grayscale images. This made
156 the filesize larger than necessary and caused some of the PerlMagick
159 2011-01-01 6.6.6-10 Glenn Randers-Pehrson <glennrp@image...>
160 * The PNG decoder now checks whether the image actually has any transparency
161 when the input file contains an alpha channel or a tRNS chunk. (Reference
162 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17748)
164 2010-12-26 6.6.6-8 Cristy <quetzlzacatenango@image...>
165 * -posterize fails with more than 40 levels (reference
166 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17741).
167 * Add support for the MacPaint image format.
168 * Eliminate spurious 'invalid colormap index' exception for 16-bit SGI images
169 (bug report by steven.sittser@fligh...).
170 * Fix user data length for the CIN image format.
172 2010-12-21 6.6.6-7 Glenn Randers-Pehrson <glennrp@image...>
173 * Use a clone instead of the main image in coders/png.c, so the image
174 can still be used later on without being affected by changes made by
176 * Added PNG:exclude-chunk and PNG:include-chunk defines.
177 * Revised the -strip option so it behaves as though
178 "-define PNG:include-chunk=none,gama" had appeared on the commandline.
179 * Avoid writing PNG ancillary chunks in the PNG/MNG/JNG encoder while
180 generating the alpha channel for a JNG image.
182 2010-12-21 6.6.6-7 Anthony Thyssen <A.Thyssen@griffith...>
183 * Removed the forced interpolation setting in AcquireResampleFilterThreadSet
184 It prevented user defined interpolation settings for -clut, and possibly
187 2010-12-17 6.6.6-6 Chris Madison <madisonblu@gmail...>
188 * Add LZMA compression support to ImageMagick.
189 * Eliminate seg-fault in MvgPrintf().
191 2010-12-17 6.6.6-6 Glenn Randers-Pehrson <glennrp@image...>
192 * Eliminated a redundant quantization step in the PNG encoder.
193 * Untangled a confusing but apparently harmless improper loop nesting
195 * Eliminated redundant "IsGray()" tests from the PNG encoder.
197 2010-12-14 6.6.6-6 Cristy <quetzlzacatenango@image...>
198 * -format "%[fx:u.p{5,5}]" no longer reports parse exception (reference
199 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17678).
201 2010-12-10 6.6.6-5 Glenn Randers-Pehrson <glennrp@image...>
202 * Make the PNG encoder always rebuild the palette, to avoid losing
203 transparency when it is out of sync with the pixel data (reference
204 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17655).
205 * Eliminated CompressColormapTransFirst() since the palette is already
206 compressed and sorted by opacity now when it's recreated.
208 2010-12-10 6.6.6-5 Cristy <quetzlzacatenango@image...>
209 * Account for virtual canvas for the -flip / -flop options (reference
210 http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=17626).
211 * Also for -transpose and transverse options
212 * Support -metric fuzz option.
214 2010-12-09 6.6.6-4 Anthony Thyssen <A.Thyssen@griffith...>
215 * Replace IsMagickColorSimilar() which provides the Fuzz Factor threshold
216 function. Note function does not calculate 'distance' in total but
217 short-circuits when threshold is reached for faster processing.
218 * Ordered Dithered handling of Alpha channel was incorrect - fixing
219 Bug was introduced v6.6.5-6
221 2010-12-03 6.6.6-3 Glenn Randers-Pehrson <glennrp@image...>
222 * Fixed two more cases where the PNG encoder lost transparency (reference
223 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17516).
225 2010-12-01 6.6.6-2 Cristy <quetzlzacatenango@image...>
226 * Affine multiplication reversed when translating (reference
227 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17570).
229 2010-11-26 6.6.6-2 Glenn Randers-Pehrson <glennrp@image...>
230 * Revised the "c7x7b" and "c7x7w" ordered-dither maps to be complementary
233 2010-11-27 6.6.6-1 Cristy <quetzlzacatenango@image...>
234 * Add support for -evaluate-sequence median.
236 2010-11-26 6.6.6-0 Glenn Randers-Pehrson <glennrp@image...>
237 * Fixed two more cases where the PNG encoder lost transparency (reference
238 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17516).
240 2010-11-23 6.6.6-0 Cristy <quetzlzacatenango@image...>
241 * The policy.xml sets not-to-exceed resource values (e.g. policy memory limit
242 1GB, -limit 2GB exceeds policy maximum so memory limit is 1GB).
243 * Support NCC (normalized cross correlation) compare metric.
245 2010-11-21 6.6.5-10 Cristy <quetzlzacatenango@image...>
246 * Fix PNG coder compile error when HDRI is enabled.
248 2010-11-17 6.6.5-9 Glenn Randers-Pehrson <glennrp@image...>
249 * Many of the problems with the PNG encoder have been fixed (reference
250 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16490).
251 * The "-type Optimize" option is now deprecated. If present, it is treated
252 by the PNG encoder the same as if the type were undefined. Optimization
253 is now always performed. No other formats used the "type Optimize" option.
254 * Merged redundant code into LosslessReduceDepth() function in the PNG codec.
256 2010-11-14 6.6.5-9 Cristy <quetzlzacatenango@image...>
257 * The splice option no longer throws spurious "pixels are not authentic"
259 * Thread the -adaptive-resize option.
260 * Set XBM coder height to height not width.
262 2010-11-14 6.6.5-9 Nicolas Robidoux <nicolas.robidoux@gmai...>
263 * Lanczos2Sharp blur tweaked. New blur = 0.9549963639785485.
265 2010-11-13 6.6.5-9 Nicolas Robidoux <nicolas.robidoux@gmai...>
266 * LanczosSharp blur tweaked to minimize worst case deviation from "perfect
267 preservation of images which only vary horizontally (or vertically)" under
268 no-op. New blur = 0.9812505644269356.
270 2010-11-08 6.6.5-8 Nicolas Robidoux <nicolas.robidoux@gmai...>
271 * Missing logical operator in tiff.c.
273 2010-11-08 6.6.5-8 Cristy <quetzlzacatenango@image...>
274 * Only save TIFF image with 1-bit depth if there is no alpha channel.
275 * Abandon PSD composite if layer is available.
276 * %[fx:mean] is the mean of the default channels (all but opacity) (reference
277 http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=17432).
279 2010-10-29 6.6.5-6 Glenn Randers-Pehrson <glennrp@image...>
280 * Added 5x5, 6x6, and 7x7 ordered-dither level maps.
282 2010-10-30 6.6.5-5 Cristy <quetzlzacatenango@image...>
283 * Do not read configure files in the current directory for the "installed"
284 version of ImageMagick.
285 * Allow numeric characters in the XPM basename (reference
286 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17385).
288 2010-10-29 6.6.5-4 Glenn Randers-Pehrson <glennrp@image...>
289 * Revised PNG palette optimization
290 * Added some debug logging in coders/png.c.
292 2010-10-28 6.6.5-3 Nicolas Robidoux <nicolas.robidoux@gmai...>
293 * More precise blur values for Lanczos2Sharp and LanczosSharp.
294 * Added location of first Mitchell crossing (=8/7) to the filters data
297 2010-10-28 6.6.5-2 Anthony Thyssen <A.Thyssen@griffith...>
298 * Added Lanczos2D* filters now named Lanczos2*
299 * Reorganization of AcquireFilter() to make it work better
301 2010-10-25 6.6.5-1 Nicolas Robidoux <nicolas.robidoux@gmai...>
302 * Clearer EWA filters (LanczosSharp etc) comments.
304 2010-10-25 6.6.5-1 Anthony Thyssen <A.Thyssen@griffith...>
305 * Added LanczosSharp (3-lobe Lanczos with sharpening)
306 * Filter sharpening factors are also always applied regardless of usage.
308 2010-10-24 6.6.5-1 Nicolas Robidoux <nicolas.robidoux@gmai...>
309 * CubicBC filter formulas simplified by constant folding. In
310 particular, P1 coefficient (always zero) removed from coeff.
312 2010-10-22 6.6.5-1 Nicolas Robidoux <nicolas.robidoux@gmai...>
313 * Revert the Robidoux filter to a Keys cubic with C=(108 sqrt 2-29)/398
314 (as already specified in the documentation).
316 2010-10-14 6.6.5-1 Cristy <quetzlzacatenango@image...>
317 * Ignore PS bounding box offsets if -page is set.
318 * Use #pragma omp master for dumping single threaded debugging information
319 (single caused a fault).
320 * Add support for -evaluate exp.
322 2010-10-12 6.6.5-0 Anthony Thyssen <A.Thyssen@griffith...>
323 * Added "filter:sigma" expert setting defining the 'sigma' for the Gaussian
324 filter only. This is similar in action to 'blur' but only for Gaussians,
325 and does not modify the filters support, allowing you to set a very small
326 sigma, without the function 'missing' all pixels.
327 (This will allow future adjustment of Gaussians for variable blur mapping)
329 2010-10-10 6.6.5-0 Cristy <quetzlzacatenango@image...>
330 * Patch for DrawableRotation() and DrawableTranslation() (reference
331 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17246).
332 * The webp format requires the webpconv delegate program (experimental).
334 2010-10-05 6.6.5-0 Anthony Thyssen <A.Thyssen@griffith...>
335 * Replaced "Robidoux" with Cubic 'Keys' filter that is near equivelent to
336 the previous sharped "Lanczos2D" filter. (C=0.31089212245300069)
337 This also is very similer to a Mitchell filter but specifically designed
338 for EWA use and is the new default filter for Distorting Images.
339 * Original sharpened Lanczos2D filter now called "Lanczos2Dsharp"
341 2010-10-08 6.6.4-10 Jerry Gay <jerry.gay@gmail..>
342 * Autodetect file type support in Makefile.PL to prevent test failures
344 2010-10-05 6.6.4-10 Anthony Thyssen <A.Thyssen@griffith...>
345 * Added new filter 'Lanczos2D' a 2-lobe Lanczos as defined by
346 Andreas Gustafsson in his thesis "Interactive Image Warping" (page 24)
347 http://www.gson.org/thesis/warping-thesis.pdf
348 * Added filter "Robidoux" which is a slightly sharpened version of the
349 "Lanczos2D" filter (blur=0.958033808) specifically designed to be less
350 'blurry' for horizontal and vertical lines in no-op distortions.
352 2010-10-05 6.6.4-10 Cristy <quetzlzacatenango@image...>
353 * Add support for "pattern:vertical2" and "pattern:horizontal2".
354 * Add support for "pattern:vertical3" and "pattern:horizontal3".
355 * Properly handle PSD layers with negative offsets.
357 2010-10-03 6.6.4-9 Cristy <quetzlzacatenango@image...>
358 * Fix memory assertion with --enable-embeddable (reference
359 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17201).
360 * Don't permit access to pixels when pinging an image (reference
361 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17194).
363 2010-10-02 6.6.4-9 Anthony Thyssen <A.Thyssen@griffith...>
364 * Added sqrt(2) blurring default for Gaussian Filter if used as
365 a Cylindrical EWA filter. This resulted removing the last aliasing
366 issue that was present in tests for Gaussian EWA resampling. Of course
367 it is still a very blurry filter for default use in EWA.
368 * Adjusted Variable Mapping Blur Composition so user arguments actual
369 relate properly to the sigma of the blur for a maximum mapping value.
370 * Fix horizon anti-alising for output-scaled perspective distortions.
371 * 'Bessel' filter is now offically and more accuritally named 'Jinc'
372 however 'Bessel' while not visible as a filter option can still be used
373 as an internal alias for 'Jinc'.
375 2010-09-28 6.6.4-8 Nicolas Robidoux <nicolas.robidoux@gmai...>
376 * Chantal Racette double checked the bounding parallelogram computation
377 in resample.c (and I tightened the comments).
379 2010-09-28 6.6.4-8 Cristy <quetzlzacatenango@image...>
380 * Temporary files not always deleted (reference
381 http://www.imagemagick.org/discourse-server/viewtopic.php?f=2&t=15960).
383 2010-09-28 6.6.4-8 Anthony Thyssen <A.Thyssen@griffith...>
384 * Bug fix for -filter point distorts (occasional generating black pixels)
386 2010-09-27 6.6.4-8 Nicolas Robidoux <nicolas.robidoux@gmai...>
387 * Simplified the ClampUpAxes code, the use of its outputs, its comments,
388 and credited Craig DeForest for the "clamp singular values" idea.
389 * No reason to have "insane" precision Sinc in resize.c: Use
390 the 1.2e-12 max. abs. relative error version for Q64 as well as Q32.
392 2010-09-27 6.6.4-8 Anthony Thyssen <A.Thyssen@griffith...>
393 * Replace the blurry "High Quality EWA" technique with a 'Clamped EWA'
394 for Distort Resampling. This makes -distort a whole lot nicer
395 and allows for the use of better cylindrical filters.
397 2010-09-26 6.6.4-7 Anthony Thyssen <A.Thyssen@griffith...>
398 * Fix Point filter for ResizeImage() caused by support limiting the
399 Box weighting function.
401 2010-09-26 6.6.4-6 Cristy <quetzlzacatenango@image...>
402 * Don't allow resize filter weights to go to zero (reference
403 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17132).
405 2010-09-24 6.6.4-6 Nicolas Robidoux <nicolas.robidoux@gmai...>
406 * Now that MagickPIL is a MagickRealType, some casts are unneeded.
408 2010-09-21 6.6.4-6 Cristy <quetzlzacatenango@image...>
409 * Do not break words if caption size is absolute (reference
410 http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=17123).
411 * Don't define HAVE_THREADS for --without-threads configure script option.
413 2010-09-20 6.6.4-5 Nicolas Robidoux <nicolas.robidoux@gmai...>
414 * Modified "magick/resize.c" so that MagickPIL is a MagickRealType number.
415 Some computations were needlessly done in long double precision because
416 PIL forced an automatic upcast wherever it appeared. Changed its name to
417 MagickREALTYPEPI. <- This was later reverted back to MagickPIL.
418 * Modified "magick/resize.c" so that Bohman uses one trig call + one sqrt
419 call instead of two trig calls.
421 2010-09-20 6.6.4-5 Anthony Thyssen <A.Thyssen@griffith...>
422 * modified "magick/resample.c" to allow use of either EWA or HQEWA (default)
423 * Removed LanczosFast from supported filters (SincFast*SincFast is faster)
425 2010-09-19 6.6.4-5 Cristy <quetzlzacatenango@image...>
426 * If IPTC profile is not embedded in an 8bim resource, declare it IPTC
428 * Support %[version] and %[copyright].
429 * Improve performance of the pixel cache.
431 2010-09-18 6.6.4-4 Cristy <quetzlzacatenango@image...>
432 * Automatically set the quantum depth to 16 for HDRI.
434 2010-09-16 6.6.4-2 Cristy <quetzlzacatenango@image...>
435 * IPTC profile not always wrapped properly inside an 8BIM profile.
436 * TIFF tile geometry must be divisible by 16.
438 2010-09-15 6.6.4-2 Anthony Thyssen <A.Thyssen@griffith...>
439 * Rename of SincPolynomial to SincFast for easier user understanding
440 * Ditto for LanczosChebyshev to LanzcosFast
442 2010-09-14 6.6.4-2 Anthony Thyssen <A.Thyssen@griffith...>
443 * Switch default resize filters to using the faster SincPolynomial
444 filter by default internally. However 'Sinc' will still use the
445 Trigonometric function, and can be used to assign the trig version
446 of Sinc() to filters using the filter expert options.
447 * The default filter for 'distort' was found to be a very blurry inaccurate
448 filter function. It was removed and replaced with a correct Gaussian
449 filter (as used by resize)
450 * Added a switch so that "-interpolate filter" will force the use of
451 a cylindrical filter for ALL pixels in distorted images. That is you can
452 use that switch to use a cylindrical filter even for images that are
453 being enlarged by the distortion. However EWA is still currently using
454 a fixed 2.0 sampling radius. This switch complements the use of "-filter
455 point" which turns off EWA filters in favor of interpolation for all
456 pixels in a distorted image. BOTH switches should not be used together.
457 * A bug in the support radius of the EWA resampling function was found,
458 now that correctly defined resize filters are being used. Suddenly Normal
459 Gaussian distortions are not so blurry, and tests with distortions of
460 the 'Rings' image show extremely good and clear results, with only minimal
461 blurring. The filter 'blur' expert option can be used to adjust this
464 The above represents a major improvement forward in the quality of the
465 image distortion operator. But near-unity distortions (no scaling) are
468 2010-09-13 6.6.4-2 Cristy <quetzlzacatenango@image...>
469 * Don't negate the geometry offset for the -extent option.
471 2010-09-09 6.6.4-1 Cristy <quetzlzacatenango@image...>
472 * The RGBO format is now listed as a supported format.
474 2010-09-07 6.6.4-1 Anthony Thyssen <A.Thyssen@griffith...>
475 * Added the Nicolas Robidoux and Chantal Racette Lanczos resize filter
476 function as "LanczosChebyshev" as faster alternative to Lanczos.
477 * Re-code Nicolas Robidoux and Chantal Racette Polynomial Approximation of
478 the Sinc Trigonometric resize filter, as a proper filter to allow
479 direct comparision and speed testing of the filter.
480 * Expanded the "-set option:filter:verbose 1" output, so as to also include
481 the actual functions and other values that were used to create the filter.
483 2010-09-02 6.6.4-0 el_supremo <digipete@shaw...>
484 * Repair a few incorrect LocaleNCompare() calls (ttf.c, ps.c).
486 2010-08-31 6.6.4-0 Cristy <quetzlzacatenango@image...>
487 * Path no longer closed if join style is round (reference
488 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16943).
489 * Add case for BGRQuantum to GetQuantumExtent().
490 * Support no compression on PCX write.
492 2010-08-23 6.6.3-10 Cristy <quetzlzacatenango@image...>
493 * Fixed bug in the raw BGRA coders (reference

504 * Throw exception if image size differs for the compare program but the
505 -subimage-search option is not specified.
507 2010-08-13 6.6.3-6 Cristy <quetzlzacatenango@image...>
508 * The AdobeRgb.tif TIFF image no longer faults under Windows (reference

510 * Add -subimage-search option to the compare utility.
512 2010-08-12 6.6.3-5 Cristy <quetzlzacatenango@image...>

514 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16833).
516 2010-08-10 6.6.3-5 Glenn Randers-Pehrson <glennrp@image...>
517 * Emit a warning if the PNG encoder can't satisfy the color type and
518 bit depth requested with a "-define" directive.
520 2010-08-07 6.6.3-4 Cristy <quetzlzacatenango@image...>
521 * The orient option sometimes improperly set "undefined" (reference
522 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16795).
523 * Only list orientation options for the -list orientation option (reference

537 * Only use the first alpha channel in PSD image.
538 * Only use XPM complying colors for XPM images (e.g. green is rgb(0,255,0)).
540 2010-07-27 6.6.3-2 Glenn Randers-Pehrson <glennrp@image...>
541 * Eliminate useless message about assuming zero delay when writing
542 a single-frame MNG, and changed it from Error to Warning when
543 writing a multiple-frame MNG.
545 2010-07-25 6.6.3-1 Glenn Randers-Pehrson <glennrp@image...>
546 * Don't "ping" a PNG image if it is embedded in a MNG. Otherwise the
547 reader tries to read MNG chunks from the interior of the embedded PNG,
548 resulting in an erroneous "corrupted image" message.
550 2010-07-09 6.6.3-1 Cristy <quetzlzacatenango@image...>
551 * Fix memory leak in for corrupt BMP images (reference
552 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16600).
553 * Repair several issues when writing to stdout (reference
554 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16620).
555 * A GIF image with the .bgr extension is still a GIF (reference
556 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16662).
558 2010-07-07 6.6.3-1 Glenn Randers-Pehrson <glennrp@image...>
559 * The PNG decoder failed to handle the tRNS chunk properly for grayscale
560 images where the PNG bit_depth was not the same as the quantum depth,
561 and the transparent color was not black.
563 2010-07-01 6.6.3-0 Chris Madison <madisonblu@gmail...>
564 * Pinging the DJVU image format no longer faults.
565 * Check for time-limit-exceeded in only one thread.
566 * Reading filenames from a file (e.g. @filenames) no longer includes the
567 utility name (side effect of StringToArgv() method).
569 2010-06-28 6.6.2-10 Cristy <quetzlzacatenango@image...>
570 * Support the tiff:fill-order define.

581 * Skip byte when DDS bitcount is 32 (reference
582 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16487).
583 * Montage now uses final background setting (e.g. montage -background none ...
584 -background lightblue show:).
585 * Do not annotate directory paths in ListFiles().
586 * Reset the image matte for png:color-type=2.
588 2010-06-17 6.6.2-7 Cristy <quetzlzacatenango@image...>
589 * Support new label:pointsize property.
590 * Miscellany->Slide Show, in the display program, now cycles through the
592 * Recognize certain hex color values (e.g. #b9e1cc00) for the -fx argument.
593 * Reduce memory requirements when dithering on the iPhone.
594 * Command line operators no longer affected by settings that appear after
595 them (e.g. -splice 10x0+0+0 -gravity center).
596 * Compute the proper DPX user data field size.
598 2010-06-15 6.6.2-6 Cristy <quetzlzacatenango@image...>
599 * Fix some nits to keep the clang compiler happy.
601 2010-06-14 6.6.2-5 Anthony Thyssen <A.Thyssen@griffith...>
602 * Fix transprancy handling for Morphology Convolve
603 * Adjustments of Hit And Miss and Edge Detection kernel definitions
604 * Added 'ThinDiagonals' Thinning Kernel + two sub-types
605 * Handling for Convolution of 1-D vertical kernels.
606 However this was removed (using #if-#endif) as I found it slower in tests!
608 2010-06-12 6.6.2-5 Cristy <quetzlzacatenango@image...>
609 * mogrify -format properly handles compressed image filename (e.g.
610 -format jpg logo.png.bz2).
611 * Respect +dither option when saving to the GIF image format.
613 2010-06-08 6.6.2-4 Cristy <quetzlzacatenango@image...>
614 * End of string sentinal is \n not \r.
616 2010-06-06 6.6.2-3 Glenn Randers-Pehrson <glennrp@image...>
617 * Don't decode pixels in coders/png.c when image->ping is set.
619 2010-06-06 6.6.2-3 Cristy <quetzlzacatenango@image...>
620 * Reset image filename when reading inline images.
621 * Don't clamp floating point values for HDRI-enabled ImageMagick.
623 2010-05-25 6.6.2-2 Anthony Thyssen <A.Thyssen@griffith...>
624 * Replaced '^' morphology kernel rotation with two variants '>' and '<'
625 * 'Skeleton' variant to thin down images as symmetrically as possible.
626 * Spelling correction: Manhatten -> Manhattan
628 2010-06-01 6.6.2-2 Glenn Randers-Pehrson <glennrp@image...>
629 * Properly scale color components of the PNG bKGD chunk.
630 * Prevent MNG divide by zero in calculation of frame_timeout. Set
631 both frame_delay and frame_timeout to infinite when ticks_per_second
632 is zero, as required by the MNG spec.
634 2010-05-31 6.6.2-2 Cristy <quetzlzacatenango@image...>
635 * Add x:silent option to prevent beeps when reading the X image format.
636 * Recognize TTF for GetMagicInfo().

639 2010-05-28 6.6.2-1 Glenn Randers-Pehrson <glennrp@image...>
640 * Prevent coders/png.c from attempting to write an empty tRNS chunk.
642 2010-05-25 6.6.2-1 Anthony Thyssen <A.Thyssen@griffith...>
643 * Fix for Square Array Rotates (off center origin rotate)
644 * Added HitAndMiss kernel Ridges2 to find 2 pixel thick ridges
645 * Added FreiChen:0,{angle} FreiChen:{angle} and FreiChen:-1 variations
646 to complete this kernels definition

654 * Use 64-bit types when compiling with the 64-bit Visual C++ compiler under
656 * Prevent MNG divide by zero in calculation of frame_delay (reference
657 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16320).
659 2010-05-23 6.6.2-0 Anthony Thyssen <A.Thyssen@griffith...>
660 * Third Re-write of MorphologyApply() to better handle compound methods.
661 * Implemented -set option:morphology:compose for merging results of
662 multiple kernels. "None" means re-iterate results with next kernel.
663 While "Undefined" means to use the internal default for a method.
664 Thinning, Thickening, HitAndMiss, Convolve, Correlate defaults to "None"
665 while HitAndMiss defaults to "Lighten" (union of all kernel results).
666 Other morphology methods defaults still to be decided.
667 * Added HitAndMiss Kernel: Ridges (find ridges and pixel width lines)
668 * Rotation Expansion of single kernels '^' and '@' flags in arguments
669 EG: -set option:showkernel 1 -morphology Convolve 'Blur:0x2^'
670 * ExpandKernelInfo() (rotation expand) now groks symmetrical kernels.
671 So the above will only produce a list of 2 kernels, not 4 kernels
673 2010-05-18 6.6.2-0 Anthony Thyssen <A.Thyssen@griffith...>
674 * Separation of internal function MorphologyApply() from
675 MorphologyImageChannel() to calls to convolve without user settings.
676 * Rewrite of MorphologyApply() to output better 'verbose' messages
677 * Better handling of Gaussian tyle filters (bug fixes)
678 * Bug fix and optimization of kernel size calculations in "gem.c"
679 * Allow '^' or '@' flags in 'user defined' kernel size arguments to
680 expand kernel into a rotated list.
681 EG: -set option:showkernel 1 -morphology Thinning '3@: 0,1,0 0,1,0 0,0,0'
682 * Allow a scaled unity kernel to be added to kernel (EdgeDet->Sharpen)
683 EG: -set option:convolve:scale [kernel_scale][^!],[unity_scale][%]
684 * Addition of "Laplacian of Gaussian" (LOG), also known as Mexican Hat
685 EG: -morphology convolve LOG:0x1
686 * Added FreiChen, Kirsch Convolution kernels
687 * Added Descrete 'Laplacian of Gaussian' kernels (Laplacian type 15 and 19)
688 * Added Edges HitAndMiss Kernel
690 2010-05-17 6.6.2-0 Cristy <quetzlzacatenango@image...>
691 * PSD images require a proper layer to support an alpha channel.
692 * Enable PFM endian support.
693 * Add context to -border for montage. Inside the parenthesis it adds a border
694 to the image otherwise it sets the border for the layout manager.
695 * 24-bit BMP images are not colormapped even if header colors != 0.
696 * Set DPX user data like this: -set profile dpx:userdata.txt.
697 * Make sure Lab => RGB => Lab survives the round trip.
699 2010-05-15 6.6.1-10 Cristy <quetzlzacatenango@image...>
700 * Use ScaleCharToQuantum() in coders/src.c (reference
701 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16229).
702 * Don't clamp HDRI EXR pixels.
704 2010-05-14 6.6.1-9 Cristy <quetzlzacatenango@image...>
705 * Increase the estimated # points for the path drawing primitive.
706 * Remove any prior resolution block from PSD before writing the new block.
708 2010-05-14 6.6.1-9 Anthony Thyssen <A.Thyssen@griffith...>
709 * Addition of more Morphological/Convolution Kernels.
710 DOG (Difference of Gaussians) and DOB (Difference of Blurs),
711 EG: -morphology convolve DOG:0x1,3
712 -morphology convolve DOB:0x1,3,90
713 * Added Prewitt, Roberts, Compass Convolution Kernels
714 * Ring Symbol Kernel (subtraction of Disk from a Disk)
716 2010-05-13 6.6.1-9 Cristy <quetzlzacatenango@image...>
717 * The pixel buffer was underallocated for some image formats when streaming.
719 2010-05-12 6.6.1-8 Anthony Thyssen <A.Thyssen@griffith...>
720 * Implementation of Pattern Matching Morphology methods
721 HitAndMiss, Thicken, Thinning
722 * Reporting of Kernel Strings that fail to parse (though not why)
723 * Parsing of Multiple Kernel Strings, generating a list of kernels
724 * Union of results from Multiple Kernels for HitAndMiss method
725 * Interated Multiple Kernels for all other morphology methods
726 * Added many new kernels for HitAndMiss and Convolution
727 Sobel, Laplacian, Cross, Peaks, Corners, LineEnds, LineJunctions,
728 ConvexHull (for Thicken), Skeleton (for Thinning)
730 2010-05-08 6.6.1-8 Glenn Randers-Pehrson <glennrp@image...>
731 * Use proper background.index when writing indexed PNG, if the background
732 color is in the palette.
734 2010-05-08 6.6.1-7 Cristy <quetzlzacatenango@image...>
735 * Fix improper 'invalid colormap index' PNG bug.
736 * Fix PerlMagick compile exception.
738 2010-05-07 6.6.1-6 Anthony Thyssen <A.Thyssen@griffith...>
739 * Added % and ! modification flags to morphology distance kernel
740 scaling factor, for easier usage.
741 * Bug fix for compose math channel handling and morphology diff usage
743 2010-05-06 6.6.1-6 Cristy <quetzlzacatenango@image...>
744 * Do not claim gray colorspace if gray image includes a non-gray pixel.
745 * Initialize BMP alpha channel to opaque for RGB images.
746 * Fixed under allocation for round rectangles.
747 * The -list option returns a 0 status as expected.
749 2010-05-06 6.6.1-6 Anthony Thyssen <A.Thyssen@griffith...>
750 * Made use of new no-'sync' channel enabled mathematical compose methods
751 for the difference morphology methods. These should now work correctly
752 for specific channels, and more importantly for alpha shaped morphology.
754 2010-05-05 6.6.1-6 Glenn Randers-Pehrson <glennrp@image...>
755 * Fixed bugs with losing the opacity channel while writing some PNG images.
756 (bug reported by Anthony T.)
758 2010-05-05 6.6.1-6 Glenn Randers-Pehrson <glennrp@image...>
759 * Simplified and corrected rowbytes calculation in coders/png.c and
762 2010-05-05 6.6.1-6 Anthony Thyssen <A.Thyssen@griffith...>
763 * Rename of "Add" and "Subtract" compositions to "ModulusAdd" and
764 "ModulusSubtract" for more clarity of there functions. Old names
765 will continue to work as expected.
766 * Fix "Minus", "ModulusAdd", and "ModulusSubtract" to follow
767 normal SVG 'Over' blending specifications, (see next for override)
768 Note that this does NOT include the "Plus" composition method which has
769 SVG definition for it to use a 'Plus' blending rather than 'Over' blending.
771 * By default mathematical compositions work as per SVG definition. That is
772 the results are synchronized with 'Over' alpha-blending (except "Plus"
773 which uses 'plus' alpha-blending).
775 By removing the default 'sync' flag from the -channel setting however
776 Break this inter-channel synchronization and do the mathematical operations
777 only on the individual channels as specified by the -channel setting.
778 That is do 'channel' math rather than 'SVG' composition.
780 With this change you can then use mathematical composition methods on
781 individual channels or even with the alpha channel of images.
783 2010-04-28 6.6.1-6 Anthony Thyssen <A.Thyssen@griffith...>
784 * Special case handling in Barrel distortion (pixel at image center)

798 * Only write one ICC profile to PSD image.
799 * Sync image colormap for PNG tRNS chunks.
800 * The -direction option now works with the -annotate and -draw options.

802 use <kbd>-define histogram:unique-colors=false</kbd> to forego this
804 * Match on literal after backslash in glob expression (reference
805 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16068).
806 * Enable JPEG-compression for grayscale TIFF images (reference
807 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16064).
808 * Don't write empty tile if tile geometry matches the image width (reference
809 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16064).
810 * Support -regard-warnings in the mogrify utility.

964 'Distance' Morphology primatives. This does not have a performance hit,
965 though is only truely applicable when the kernel is asymmetric. Note that
966 'Erode' does not use a 'reflected' kernel, so that 'Open' and 'Close'
967 operations work properly. This 'reflected usage is defined by online
968 morphology lecture notes (Google for "EECE Binary Morphology")
969 * Added convolve kernel scaling setting "-set option:convolve:scale N"
970 If undefined morphology convolve does not do any scaling or normalization
971 of the convolution kernel. A value of 0.0 causes normalization for both

995 2010-01-04 6.5.9-0 Anthony Thyssen <A.Thyssen@griffith...>
996 * Added Kernel Generator to generate kernels from user strings, which
997 allows the generation in many built in kernels for both Convolution
998 and other Morphological methods. New Kernels currently include..
999 Convolution: Gaussian, Blur, Comet
1000 Morphological: Rectangle, Square, Diamond, Disk, Plus
1001 Distance: Chebyshev, Manhatten, Knight, Euclidean
1002 And both old and new (rectangular) user defined kernel specifications
1003 including the use of 'nan' to represent elements which are not part
1004 of the kernel definition. List built-in kernel types use "-list kernel"
1005 * Added -morphology {method}[:{iteration}] {kernel_string}
1006 Initial methods includes no only the basic morphology methods: Dilate,
1007 Erode, Open, Close; and a pixel color preserving 'Intensity' version, but
1008 also the special methods: Convolve, and Distance. Of course the
1009 appropriate kernel should be provided for each specific method.
1011 2010-01-01 6.5.9-0 Cristy <quetzlzacatenango@image...>
1012 * Add OpenCL-enabled filter (e.g. convert image.png -process
1013 "convolve '-1, -1, -1, -1, 9, -1, -1, -1, -1'" image.jpg).
1014 * Added StringTo...() processing functions

1248 renamed to trans_alpha in PNG version 1.4.
1250 2009-07-29 6.5.4-7 Cristy <quetzlzacatenango@image...>
1251 * Replace color blending in DrawGradientImage() to use Composite Blend.
1252 this makes Gradients handle transparency correctly!
1254 2009-07-28 6.5.4-7 Cristy <quetzlzacatenango@image...>
1255 * The -thumbnail option no longer removes color profiles (reference
1256 http://www.imagemagick.org/discourse-server/viewtopic.php?f=2&t=14312).

1258 * Check for localtime() NULL return.
1259 * import --help requires an X server (reference
1260 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=14323).
1261 * Fails to load MS Windows icons with compressed PNG elements (reference
1262 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=14324).
1264 2009-07-25 6.5.4-6 Cristy <quetzlzacatenango@image...>
1265 * Support the new JPEG version 7 delegate library.
1267 2009-07-24 6.5.4-6 Alexander E. Patrakov <patrakov@gmail...>
1268 * Incorrect use of setjmp in coders/png.c.

1271 * We broke -scene when we fixed the -dispose option. Try again.
1273 2009-07-21 6.5.4-4 Cristy <quetzlzacatenango@image...>
1274 * Update autoconf support files.
1275 * More than one -dispose setting overwrote previous settings (reference
1276 http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=14252).
1277 * Don't use JPEG's color reduction algorithm for less than 8 colors.
1279 2009-07-13 6.5.4-3 Anthony Thyssen <A.Thyssen@griffith...>
1280 * Final testing and bug fixes for all mathematical compose methods
1281 Including non-overlapping regions bugs found in in operators Divide,
1282 ColorDodge, VividLight. And the handling of transparency to follow
1283 standard 'Over' Blending in Divide. Only math methods not looked at are
1284 the addition methods Plus, Add, Minus, and Subtract, which do not follow
1285 normal 'Over' alpha blending behaviour, for the purposes of mask handling.
1287 2009-07-12 6.5.4-3 Anthony Thyssen <A.Thyssen@griffith...>
1288 * Addition of user definable 'Mathematics' compose method
1289 -compose Mathematics -set option:compose:args A,B,C,D -composite
1290 Will implement the formula f(Sc,Dc) = A*Sc*Dc + B*Sc + C*Dc + D
1291 this lets you implement most smooth polynomial compose methods.
1292 (requested by Fred WienHaus)

1301 http://www.simplefilter.de/en/basics/mixmods.html
1302 Added extra composition modes:
1303 VividLight, PinLight, LinearBurn, LinearDodge
1304 NOTE: 'LinearBurn' the same as 'Plus' but with the normal 'Over' blending.
1306 2009-07-10 6.5.4-3 Anthony Thyssen <A.Thyssen@griffith...>
1307 * Re-coding of Composite methods HardLight, SoftLight, Overlay, LinearLight,
1308 ColorBurn, ColorDodge, Multiply, Screen to make it more readable, easier
1309 to debug, and directly comparable to SVG specifications.
1310 * Specifications changed for SoftLight, ColorBurn, ColorDodge
1311 Though only SoftLight changed to significantly.
1312 * However implementation errors were found for ColorBurn, LinearLight

1331 * Can't stat() a Zip or Bzip opaque structure.
1332 * DPX user bits are no longer truncated.
1333 * Return image colorspace for -format [%colorspace] option.
1334 * ThumbnailImage(): don't subsample if image is already thumbnail size.
1336 2009-06-23 6.5.4-0 Anthony Thyssen <A.Thyssen@griffith...>
1337 * Automatic determination of B from C and C from B for a 'Keys Filter'
1338 when using the B,C Cubic Filter Expert options was broken.
1339 See http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=14037
1341 2009-06-19 6.5.4-0 Anthony Thyssen <A.Thyssen@griffith...>
1342 * Added -compose 'Blur', variable blur mapping to CompositeImages

1356 * Improve FITS keyword parser.
1358 2009-06-14 6.5.3-7 Anthony Thyssen <A.Thyssen@griffith...>
1359 * Cleanup of compose 'displace' of old useless code that is not used.
1360 * Implement a compose 'distort' mapping method,
1361 This is basically exactly like 'displace' but relative to a fixed point
1362 which may be user supplied as +X+Y
1363 * Default scaling to width/2 and height/2 of overlay (100% scale)
1364 with a distortion 'center' to the middle of the overlay image
1365 * If a '%' flag given scale displacement relative to image size
1366 * If a '!' flag given make scale and center relative to 'background' image
1367 instead of the overlay map.
1368 * If no 'height' scale given, use the X scale.
1370 2009-06-13 6.5.3-6 Anthony Thyssen <A.Thyssen@griffith...>
1371 * Fixed bug for compose methods, Hue, Saturate, Luminize

1376 * Do not advance when finalizing image settings in the mogrify program.
1378 2009-06-11 6.5.3-5 Anthony Thyssen <A.Thyssen@griffith...>
1379 * Fixed "convert" to merge the third 'mask' image into the 'source' image
1380 for correct handling of 2 dimensional -compose "displace".
1381 * Fixed PerlMagick Composite() for the same thing.
1382 * Modified compose "Displace" so displacement image's alpha channel can be
1383 used to mask the transparency of the overlay area.
1385 2009-06-07 6.5.3-4 Cristy <quetzlzacatenango@image...>
1386 * Added the HALD image Color LUT, and a no-op HALD: image generator.
1387 See Introduction at http://www.quelsolaar.com/technology/clut.html
1389 2009-06-07 6.5.3-4 Anthony Thyssen <A.Thyssen@griffith...>
1390 * Changed CompositeImageChannel() so that extra compose arguments are
1391 now passed in the ImageArtifact "compose:args". This can be assigned to
1392 images using -set "option:compose:args" 'args' where args are defined
1393 using 'geometry' style or 'comma separated numbers'.
1394 * Declared the special flag needed for Composite Tiling as the ImageArtifact
1395 "compose:outside-overlay".
1396 * Documentation update for CompositeImageChannel() in Core Library to
1397 reflect these changes.
1398 * Documentation update for DistortImage() in Core Library with the extra
1399 ImageArtifact controls it can use.

1448 2009-05-14 6.5.2-5 Glenn Randers-Pehrson <glennrp@image...>
1449 * Updated help output and command-line options documentation to bring
1450 the -alpha options up to date with what's actually in the code.
1452 2009-05-13 6.5.2-5 Glenn Randers-Pehrson <glennrp@image...>
1453 * Change "depreciated" to "deprecated" in several files.

1462 * Combined layer of transparent PSD image was not being read properly.
1464 2009-05-06 6.5.2-3 Glenn Randers-Pehrson <glennrp@image...>
1465 * Progress on "-define png:bit-depth=value" and "-define png:color-type=value"
1466 It is now able to write an opaque black-and-white image in any of the 15
1467 valid combinations of PNG color-type and bit-depth.
1468 * Fixed a regression with writing sub-8-bit grayscale PNGs.
1470 2009-05-06 6.5.2-2 Chris Madison <madisonblu@gmail...>
1471 * Create 8-bit TIFF images if -depth is set to 8 and HDRI-enable ImageMagick.
1473 2009-05-04 6.5.2-1 Chris Madison <madisonblu@gmail...>
1474 * Accept file lists on the command line (e.g. echo "rose: rose.png" |
1476 * Duplicate line in tiff.c breaking read of zip compressed tif (reference
1477 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=13688).
1478 * Support policies to permit or deny any coder, delegate, filter, or file
1479 path (see policy.xml).
1481 2009-05-02 6.5.2-0 Chris Madison <madisonblu@gmail...>
1482 * The mogrify -crop option returns multiple images if an x/y offset is not
1483 specified (e.g. -crop 100x100).

1485 http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=13671).
1487 2009-05-01 6.5.2-0 Glenn Randers-Pehrson <glennrp@image...>
1488 * Accept "-define png:bit-depth=value" and "-define png:color-type=value"
1489 options. This is work-in-progress with the objective of being able to
1490 precisely specify the type of PNG file to be written. The previously-used
1491 internal attribute "png:bit-depth" that was used to communicate between
1492 the PNG writer and the JNG writer is changed to "png:bit-depth-written".
1493 This feature needs testing. It is important to note that this feature
1494 cannot be used to force the PNG to use a bit-depth or color-type that
1495 does not losslessly represent the image. You can, however, cause
1496 the writer to use a larger depth or to use the RGB colorspace when
1497 grayscale or indexed would have been sufficent.
1499 2009-05-01 6.5.1-10 Anthony Thyssen <A.Thyssen@griffith...>
1500 * Fixed the Rmin usage in Depolar and Polar distortions
1501 * The 6th argument (Ato) for Polar/Depolar is now optional and defaults

1504 2009-04-30 6.5.1-10 Cristy <quetzlzacatenango@image...>
1505 * Do not return a black image for -channel RGBA -gaussian (reference
1506 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=13669).
1508 2009-04-28 6.5.1-9 Cristy <quetzlzacatenango@image...>

1519 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=13626).
1520 * Support multiple JPEG images encapsulated within DICOM.
1522 2009-04-23 6.5.1-6 Cristy <quetzlzacatenango@image...>
1523 * Msys does not understand NAME_MAX.

1528 2009-04-21 6.5.1-4 Glenn Randers-Pehrson <glennrp@image...>
1529 * Check error return from CompressColormapTransFirst() in coders/png.c
1531 2009-04-21 6.5.1-4 Glenn Randers-Pehrson <glennrp@image...>
1532 * Refrain from modifying image struct members (color, depth, matte)
1533 while writing PNG datastreams.
1535 2009-04-21 6.5.1-4 Glenn Randers-Pehrson <glennrp@image...>
1536 * Sometimes the PNG8: format would produce 1-, 2-, or 4-bit PNG datastreams.
1537 Now it always produces 8-bit datastreams as users probably expect.
1539 2009-04-21 6.5.1-4 Glenn Randers-Pehrson <glennrp@image...>
1540 * Suppressed "shadowed declaration" warnings in coders/jpeg.c and

1560 2009-04-11 6.5.1-2 Anthony Thyssen <A.Thyssen@griffith...>
1561 * Rename existing "Bilinear" distortion as "BilinearReverse"
1562 * Added forward mapped bilinear distort as "BilinearForward"
1563 * The "Bilinear" distort is temporarily obsoleted but will eventually
1564 be added as a "BilinearReverse" and "BilinearForward" combination
1565 mapping though a unit square.
1566 * Sparse Gradient internally uses "BilinearReverse" for its "Bilinear"
1567 gradient function as that method is the direct use of such equations.

2213 Function maps black and white values to the given level values.
2214 Rather than mapping the given level values to black and white.
2215 Bacically a 'reverse-level' function, with different input args.
2216 * Set +level or a '!' flag in -level or LevelImage() to call
2217 the new 'reverse-level' function LevelizeImageChannels().
2218 * More work on IsMagickColorSimular() to fix relationship between
2219 transparent-black and opaque-black, which was matched as 'simular'.
2220 Also attempts to fix 'K' channel handling for CMYK colorspace.
2221 More work on this to come.

2569 2007-11-02 6.3.6-6 Cristy <quetzlzacatenango@image...>
2570 * Upgrade to FPX version libfpx-1.2.0.14 (reference
2571 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=10041).
2572 * Modules are searched first in the directories specified by the environment
2573 variables, and then -- if the desired module is not found -- in the
2574 compiled-in path. (reference
2575 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=10039).

2590 * Further expandsion and handling of filters with expert options.
2591 -filter selects from a table of standard filter settings, while
2592 expert options allow complete selection of filter, windowing, support
2593 and blurring options. Includes automatic switch from Sinc to Bessel
2594 for operators using 2 dimentional cylindrical filter, rather than
2595 two pass 1 dimentional orthogonal filters.
2597 2007-10-14 6.3.6-3 Cristy <quetzlzacatenango@image...>
2598 * Obsolete -support (set filter blur factor)
2599 * Expandsion to add -set/define filter options
2601 2007-10-12 6.3.6-2 Anthony <anthony@griffith...>
2602 * Least Squares coordinate handling added for -distort methods Affine,
2603 Perspective, Bilinear. This allows for more than the minimal number of
2604 coordinates to be used to 'fit' a distortion function to an image.
2605 This addition will allow the use of image registration to generate
2606 panarama overviews and better geographical coordinate correction.
2607 * Cosolidated the simular methods FlattenImage() and MosaicImage()
2608 into a new layers function MergeImageLayers() method, adding 'flatten'
2609 and 'mosaic' layer methods.
2610 * Addition of another simular layers method 'merge' which 'unlocks' the
2611 normal flatten/mosaic layer merger from the origin, The resulting image
2612 will have a virtual canvas of minimal size with an offset. Also images
2613 with negative offsets will not be clipped by the 'merge' form of the
2614 command. This was created for better layering of distorted images, such
2615 as panarama overlays.
2616 * Bug fix in handling transparency for EWA resampling.
2617 * Access to Resize Filter Functions from resize.c (for resample.c)
2618 with posible future filter sources... Acquire/Destory/Call ResizeFilter()
2619 * All resize filters added to resampling, but filter handling is incomplete.
2621 2007-10-05 6.3.6-2 Cristy <quetzlzacatenango@image...>
2622 * The box filter no longer produces a black grid when resizing an image
2624 * Respect cropbox for PDF with a subimage specification (e.g.
2626 * Detect proper PDF bounding box when offsets are negative.
2628 2007-10-02 6.3.6-1 Cristy <quetzlzacatenango@image...>
2629 * Speed up the Fx interpreter.
2630 * Use ULL not ui64 for MinGW 64-bit constants.
2631 * Call SyncCacheView() instead of SyncImagePixels() in WaveImage().
2632 * Close all references to a pixel cache on disk before removing the temporary
2633 file as required under Windows.
2635 2007-09-29 6.3.6-0 Anthony <anthony@griffith...>
2636 * Added Scaling 'derivitives' to -distort Arc, so image arcing is now
2637 sharp and clear as you approach the center of the distort.
2638 * Added " -set option:distort:viewport 'geometry' " special option
2639 that can be used to override the output image size and offset.
2640 * Fixed experimental use of -filter and -support in Resampling (more later).
2641 * Changed order for coordinate arguments in -distort (for later leastsq
2642 multiple coordinate distortion function fitting)
2644 2007-09-22 6.3.6-0 Cristy <quetzlzacatenango@image...>
2645 * Check the API version and quantum depth before loading a coder module or
2646 image filter (reference
2647 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=9780).
2648 * Add exception to the image filter signature.
2649 * Get the execution path under Mac OS X.
2650 * TIFFTAG_STRIPBYTECOUNTS requires a uint32 pointer (magick/compress.c).
2651 * Fixed memory leak in CloneString() (reference
2652 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=9763).
2653 * Set S_IRUSR | S_IWUSR | S_IRGRP mode when writing a file in
2656 2007-09-18 6.3.5-9 Anthony <anthony@griffith...>
2657 * Bug fix for +distort in Perspective, also effected PerspectiveProjection
2659 2007-09-17 6.3.5-10 Cristy <quetzlzacatenango@image...>
2660 * Replace all InterpolatePixelColor() calls to use the ResamplePixelColor()
2662 * Map the display program pan icon window for each oversized image.
2663 * The ufraw delegate does not like quotes around the output filename.
2664 * Adjust the sensitivity of a few PerlMagick tests to pass the validation on
2665 a 64-bit FreeBSD system.
2666 * The -level option now works properly for colormapped images.
2667 * Allow Extrapolated blending of images using -blend
2668 http://netpbm.sourceforge.net/doc/extendedopacity.html
2670 2007-09-12 6.3.5-9 Anthony <anthony@griffith...>
2671 * Major Addition, Area Resampling Functions, (scaled interpolation)
2672 for pixel lookup in Distortion functions. This improves the look in
2673 areas of minification enormousally, especially in situations of infinite
2674 tiling and horizon views. All virtual pixel methods have been handled
2675 to minimise computation time involved with area resampling. To use the
2676 new function distortions need to be able to determine scaling vectors
2677 (distortion function derivitives) for correct working. All
2678 -distort methods, except Arc, uses scaled area resampling.
2679 * Improvements to perspective distort method, to include the correct
2680 differentation between the 'ground' on which the image lies, and the
2681 'sky', the color of which can be set using the -mattecolor setting
2682 (as the distortion invalid pixel color). Background color is retains
2683 for surrounding ground areas. The horizon is also correct anti-aliased
2684 and transparent colors are also allowed, allowing you to add backdrops
2685 of gradients and patterns.
