6 * Support 16-bit per pixel YUV image files.
glennrpd86db542011-02-09 13:43:45 +00007 * Fix off-by-one error in PosterizeImage().
cristyd1a2c0f2011-02-09 14:14:50 +00008 * Posterize now distributes color uniformally (reference
9 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17623).
cristy4d727152011-02-10 19:57:21 +000010 * Add -smush option (reference

23 * Check if the font is null in RenderFreetype() to prevent fault (reference
24 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17890).
cristyfd5b45c2011-02-03 01:17:03 +000025 * Eliminate fault when reading WMF image files (reference
26 http://www.imagemagick.org/discourse-server/viewtopic.php?f=2&t=17971).
cristya97426c2011-02-04 01:41:27 +000027 * Support multi-page transparent Postscript and PDF image files.
cristye6529ff2011-02-04 20:05:32 +000028 * The compare fuzz metric now returns the same correct value for
anthonyb4d5f862011-02-06 01:12:54 +000029 'xc:white xc:blue -alpha off' and 'xc:white xc:blue -alpha on'.

36 * Renamed variables, macros, and functions defined/declared in coders/png.c
37 that were in the libpng namespace (beginning with "png_" or "PNG_").

glennrp0fd86dc2011-01-25 19:56:36 +000040 * Removed a call to GetNumberColors() from the PNG encoder that was
41 only there for debugging purposes and was consuming a huge amount
glennrp26bdeb52011-01-25 20:15:13 +000042 of CPU time. (reference
43 http://www.imagemagick.org/discourse-server/viewtopic.php?f=2&t=17799).
glennrp0e319732011-01-25 21:53:13 +000044 * Sometimes black was still written as transparent, when the PNG
glennrp614049a2011-01-27 03:49:06 +000045 encoder received an image with image->matte==true no transparent
46 pixels were present. (reference

glennrp0fd86dc2011-01-25 19:56:36 +000050 * Remove memory leak from ThrowFileException() macro (reference
cristy5bf97b52011-01-24 13:21:15 +000051 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17908).
cristy83b6e792011-01-26 15:46:06 +000052 * Multiple blue error count by 'count' in ClassifyImageColors()
cristyc1c5b3b2011-02-01 01:12:07 +000053 * Add support for the AAI image format.

56 * Accept quoted file paths in indirect file references (e.g. @myFiles.txt).
57
glennrp21eec3d2011-01-19 15:21:02 +0000582011-01-19 6.6.7-2 Glenn Randers-Pehrson <glennrp@image...>
glennrpa6a06632011-01-19 15:15:34 +000059 * Changed the PNG encoder's "transparent_color" from a UShortPixelPacket
60 to LongPixelPacket and made the default (65537,65537,65537), which
61 can never occur in the PNG image data. Previously the default was
glennrp21eec3d2011-01-19 15:21:02 +000062 (0,0,0) and black pixels would be rendered as as transparent when
glennrp4df5af82011-01-20 00:20:45 +000063 no tRNS chunk was present in the input, which has caused problems
64 with some test cases since version 6.6.6-10.
glennrp21eec3d2011-01-19 15:21:02 +000065 * Improved the PNG_BUILD_PALETTE section to count opaque, transparent,
glennrp614049a2011-01-27 03:49:06 +000066 and semitransparent pixels separately. Previously it wasn't always
67 possible to determine if there was a single fully-transparent color,
glennrp4df5af82011-01-20 00:20:45 +000068 to decide whether to write an RGBA or Gray-Alpha image or an RGB or
69 Gray image with a tRNS chunk.

72 * Do not reset image next / previous when detach argument is false for
73 CloneImage().
74 * Inline cropping no longer fails for inline raw images (e.g.
75 -size 640x480 -depth 8 'gray:logo[100x100+200+200]').

78 * Don't let the PNG encoder try to sort the colormap when there are more
79 than 256 colors in the image. (reference

glennrpe4017e32011-01-08 17:16:09 +0000862011-01-08 6.6.7-1 Glenn Randers-Pehrson <glennrp@image...>
87 * Quieted some inconsequential warnings in the PNG codec due to a
88 change in the type of the PNG iCCP profile from png_charp to png_bytep
89 in libpng-1.5.0.
90
cristyd63c0502011-01-03 15:45:11 +0000912011-01-03 6.6.7-0 Cristy <quetzlzacatenango@image...>
92 * Handle negative heights for ICO images.

glennrpf42cff62011-01-02 20:01:17 +000095 * Recent changes sometimes caused the PNG encoder to select colortype=2
glennrp1e781a92011-01-04 14:52:45 +000096 (Truecolor) instead of 0 (Grayscale) for grayscale images. This made
97 the filesize larger than necessary and caused some of the PerlMagick
98 tests to fail.

glennrpc8cbc5d2011-01-01 00:12:34 +0000101 * The PNG decoder now checks whether the image actually has any transparency
glennrp0684d242011-01-07 15:08:41 +0000102 when the input file contains an alpha channel or a tRNS chunk. (Reference

106 * -posterize fails with more than 40 levels (reference
107 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17741).
cristy03043dd2010-12-28 18:48:57 +0000108 * Add support for the MacPaint image format.
glennrpf42cff62011-01-02 20:01:17 +0000109 * Eliminate spurious 'invalid colormap index' exception for 16-bit SGI images
cristy667a8922010-12-29 13:43:35 +0000110 (bug report by steven.sittser@fligh...).
cristy97450ff2010-12-29 17:29:17 +0000111 * Fix user data length for the CIN image format.

114 * Use a clone instead of the main image in coders/png.c, so the image
115 can still be used later on without being affected by changes made by
116 the PNG encoder.
glennrp26f37912010-12-23 16:22:42 +0000117 * Added PNG:exclude-chunk and PNG:include-chunk defines.
glennrp36a7ad82010-12-23 16:26:42 +0000118 * Revised the -strip option so it behaves as though
glennrp9eb2d1a2010-12-24 00:33:05 +0000119 "-define PNG:include-chunk=none,gama" had appeared on the commandline.
glennrp0effd182010-12-23 19:15:48 +0000120 * Avoid writing PNG ancillary chunks in the PNG/MNG/JNG encoder while
121 generating the alpha channel for a JNG image.

anthonya27af282010-12-21 02:43:33 +00001232010-12-21 6.6.6-7 Anthony Thyssen <A.Thyssen@griffith...>
124 * Removed the forced interpolation setting in AcquireResampleFilterThreadSet
cristy330af6c2010-12-21 14:36:06 +0000125 It prevented user defined interpolation settings for -clut, and possibly
anthonya27af282010-12-21 02:43:33 +0000126 other usage.

133 * Eliminated a redundant quantization step in the PNG encoder.
134 * Untangled a confusing but apparently harmless improper loop nesting
135 in the PNG encoder.
136 * Eliminated redundant "IsGray()" tests from the PNG encoder.

cristyf364ed42010-12-15 01:54:43 +00001382010-12-14 6.6.6-6 Cristy <quetzlzacatenango@image...>
139 * -format "%[fx:u.p{5,5}]" no longer reports parse exception (reference
140 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17678).
141

143 * Make the PNG encoder always rebuild the palette, to avoid losing
144 transparency when it is out of sync with the pixel data (reference
145 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17655).
glennrpd6bf1612010-12-17 17:28:54 +0000146 * Eliminated CompressColormapTransFirst() since the palette is already
glennrp101643d2010-12-23 13:02:50 +0000147 compressed and sorted by opacity now when it's recreated.

156 * Replace IsMagickColorSimilar() which provides the Fuzz Factor threshold
157 function. Note function does not calculate 'distance' in total but
158 short-circuits when threshold is reached for faster processing.
anthonybffd2672010-12-06 06:10:48 +0000159 * Ordered Dithered handling of Alpha channel was incorrect - fixing

182 * The policy.xml sets not-to-exceed resource values (e.g. policy memory limit
183 1GB, -limit 2GB exceeds policy maximum so memory limit is 1GB).
cristy34d6fdc2010-11-26 19:06:08 +0000184 * Support NCC (normalized cross correlation) compare metric.

190 * Many of the problems with the PNG encoder have been fixed (reference
glennrp6d1b79d2010-11-20 13:55:15 +0000191 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16490).
glennrp45c22512010-11-21 17:46:40 +0000192 * The "-type Optimize" option is now deprecated. If present, it is treated
193 by the PNG encoder the same as if the type were undefined. Optimization
glennrpc63e3c12010-11-29 14:14:47 +0000194 is now always performed. No other formats used the "type Optimize" option.
glennrp0c3e06b2010-11-19 13:45:02 +0000195 * Merged redundant code into LosslessReduceDepth() function in the PNG codec.

246 * Added LanczosSharp (3-lobe Lanczos with sharpening)

264 * Added "filter:sigma" expert setting defining the 'sigma' for the Gaussian
265 filter only. This is similar in action to 'blur' but only for Gaussians,
266 and does not modify the filters support, allowing you to set a very small
267 sigma, without the function 'missing' all pixels.
268 (This will allow future adjustment of Gaussians for variable blur mapping)

276 * Replaced "Robidoux" with Cubic 'Keys' filter that is near equivelent to
277 the previous sharped "Lanczos2D" filter. (C=0.31089212245300069)
anthonyf5e76ef2010-10-12 01:22:01 +0000278 This also is very similer to a Mitchell filter but specifically designed
279 for EWA use and is the new default filter for Distorting Images.
anthonye5f06452010-10-12 05:48:17 +0000280 * Original sharpened Lanczos2D filter now called "Lanczos2Dsharp"

anthony853d6972010-10-08 06:01:31 +0000286 * Added new filter 'Lanczos2D' a 2-lobe Lanczos as defined by
287 Andreas Gustafsson in his thesis "Interactive Image Warping" (page 24)
288 http://www.gson.org/thesis/warping-thesis.pdf
anthonyd5fae5d2010-10-10 03:59:06 +0000289 * Added filter "Robidoux" which is a slightly sharpened version of the
anthony02b4cb42010-10-10 04:54:35 +0000290 "Lanczos2D" filter (blur=0.958033808) specifically designed to be less
291 'blurry' for horizontal and vertical lines in no-op distortions.

glennrpc63e3c12010-11-29 14:14:47 +0000305 * Added sqrt(2) blurring default for Gaussian Filter if used as
anthony61b5ddd2010-10-05 02:33:31 +0000306 a Cylindrical EWA filter. This resulted removing the last aliasing
307 issue that was present in tests for Gaussian EWA resampling. Of course
glennrpc63e3c12010-11-29 14:14:47 +0000308 it is still a very blurry filter for default use in EWA.
anthony10b8bc82010-10-02 12:48:46 +0000309 * Adjusted Variable Mapping Blur Composition so user arguments actual
310 relate properly to the sigma of the blur for a maximum mapping value.
anthony61b5ddd2010-10-05 02:33:31 +0000311 * Fix horizon anti-alising for output-scaled perspective distortions.
312 * 'Bessel' filter is now offically and more accuritally named 'Jinc'
anthony48f77622010-10-03 14:32:31 +0000313 however 'Bessel' while not visible as a filter option can still be used
314 as an internal alias for 'Jinc'.

anthony61b5ddd2010-10-05 02:33:31 +0000328 * Simplified the ClampUpAxes code, the use of its outputs, its comments,
329 and credited Craig DeForest for the "clamp singular values" idea.
nicolasc2d28f02010-09-27 18:56:15 +0000330 * No reason to have "insane" precision Sinc in resize.c: Use
331 the 1.2e-12 max. abs. relative error version for Q64 as well as Q32.

334 * Replace the blurry "High Quality EWA" technique with a 'Clamped EWA'
nicolasb05c3df2010-09-27 15:58:42 +0000335 for Distort Resampling. This makes -distort a whole lot nicer
anthonyc7b82f22010-09-27 10:42:29 +0000336 and allows for the use of better cylindrical filters.

nicolas92375332010-09-21 00:32:38 +0000355 * Modified "magick/resize.c" so that MagickPIL is a MagickRealType number.
nicolas94a41852010-09-21 14:35:09 +0000356 Some computations were needlessly done in long double precision because
357 PIL forced an automatic upcast wherever it appeared. Changed its name to
nicolasb05c3df2010-09-27 15:58:42 +0000358 MagickREALTYPEPI. <- This was later reverted back to MagickPIL.
nicolas94a41852010-09-21 14:35:09 +0000359 * Modified "magick/resize.c" so that Bohman uses one trig call + one sqrt

376 * IPTC profile not always wrapped properly inside an 8BIM profile.
anthony165bd162010-09-20 01:06:26 +0000377 * TIFF tile geometry must be divisible by 16.

glennrpf5e546d2010-09-18 19:12:38 +0000380 * Rename of SincPolynomial to SincFast for easier user understanding
anthonyba5a7c32010-09-15 02:42:25 +0000381 * Ditto for LanczosChebyshev to LanzcosFast
382
anthony5708fc62010-09-14 13:52:50 +00003832010-09-14 6.6.4-2 Anthony Thyssen <A.Thyssen@griffith...>
384 * Switch default resize filters to using the faster SincPolynomial
glennrpf5e546d2010-09-18 19:12:38 +0000385 filter by default internally. However 'Sinc' will still use the
anthony5708fc62010-09-14 13:52:50 +0000386 Trigonometric function, and can be used to assign the trig version
387 of Sinc() to filters using the filter expert options.
anthony165bd162010-09-20 01:06:26 +0000388 * The default filter for 'distort' was found to be a very blurry inaccurate
389 filter function. It was removed and replaced with a correct Gaussian
390 filter (as used by resize)
anthony5708fc62010-09-14 13:52:50 +0000391 * Added a switch so that "-interpolate filter" will force the use of
392 a cylindrical filter for ALL pixels in distorted images. That is you can
glennrp705a1ef2010-09-16 11:31:26 +0000393 use that switch to use a cylindrical filter even for images that are
anthony165bd162010-09-20 01:06:26 +0000394 being enlarged by the distortion. However EWA is still currently using
395 a fixed 2.0 sampling radius. This switch complements the use of "-filter
396 point" which turns off EWA filters in favor of interpolation for all
397 pixels in a distorted image. BOTH switches should not be used together.
anthony5708fc62010-09-14 13:52:50 +0000398 * A bug in the support radius of the EWA resampling function was found,
399 now that correctly defined resize filters are being used. Suddenly Normal
400 Gaussian distortions are not so blurry, and tests with distortions of
401 the 'Rings' image show extremely good and clear results, with only minimal
402 blurring. The filter 'blur' expert option can be used to adjust this
403 further.
404
glennrp705a1ef2010-09-16 11:31:26 +0000405 The above represents a major improvement forward in the quality of the
anthony165bd162010-09-20 01:06:26 +0000406 image distortion operator. But near-unity distortions (no scaling) are
407 still overly blurry.

anthonyb6d08c52010-09-13 01:17:04 +0000416 * Added the Nicolas Robidoux and Chantal Racette Lanczos resize filter
glennrpf5e546d2010-09-18 19:12:38 +0000417 function as "LanczosChebyshev" as faster alternative to Lanczos.
anthony9d7245a2010-09-07 10:18:56 +0000418 * Re-code Nicolas Robidoux and Chantal Racette Polynomial Approximation of

691 * Made use of new no-'sync' channel enabled mathematical compose methods
692 for the difference morphology methods. These should now work correctly
glennrpa3adfd92010-05-14 18:12:46 +0000693 for specific channels, and more importantly for alpha shaped morphology.

704 * Rename of "Add" and "Subtract" compositions to "ModulusAdd" and
705 "ModulusSubtract" for more clarity of there functions. Old names
706 will continue to work as expected.
anthony320be8b2010-05-05 06:16:16 +0000707 * Fix "Minus", "ModulusAdd", and "ModulusSubtract" to follow
anthonyc5d68fe2010-05-05 05:27:54 +0000708 normal SVG 'Over' blending specifications, (see next for override)
anthony320be8b2010-05-05 06:16:16 +0000709 Note that this does NOT include the "Plus" composition method which has
glennrpa3adfd92010-05-14 18:12:46 +0000710 SVG definition for it to use a 'Plus' blending rather than 'Over' blending.
anthony320be8b2010-05-05 06:16:16 +0000711
712 * By default mathematical compositions work as per SVG definition. That is
glennrpa3adfd92010-05-14 18:12:46 +0000713 the results are synchronized with 'Over' alpha-blending (except "Plus"
anthony320be8b2010-05-05 06:16:16 +0000714 which uses 'plus' alpha-blending).
715
716 By removing the default 'sync' flag from the -channel setting however
glennrpa3adfd92010-05-14 18:12:46 +0000717 Break this inter-channel synchronization and do the mathematical operations
anthony320be8b2010-05-05 06:16:16 +0000718 only on the individual channels as specified by the -channel setting.
719 That is do 'channel' math rather than 'SVG' composition.
720
721 With this change you can then use mathematical composition methods on
722 individual channels or even with the alpha channel of images.

901
9022010-01-24 6.5.9-1 Anthony Thyssen <A.Thyssen@griffith...>
903 * added use of -precision in 'showkernel' output of -morphology
904 * correct use of a 'reflected kernel' for 'Convolve' 'Dilate' and
905 'Distance' Morphology primatives. This does not have a performance hit,
906 though is only truely applicable when the kernel is asymmetric. Note that
907 'Erode' does not use a 'reflected' kernel, so that 'Open' and 'Close'
908 operations work properly. This 'reflected usage is defined by online
909 morphology lecture notes (Google for "EECE Binary Morphology")
910 * Added convolve kernel scaling setting "-set option:convolve:scale N"
911 If undefined morphology convolve does not do any scaling or normalization
912 of the convolution kernel. A value of 0.0 causes normalization for both
913 zero and non-zero (added weights) kernel types.

938 allows the generation in many built in kernels for both Convolution
939 and other Morphological methods. New Kernels currently include..
940 Convolution: Gaussian, Blur, Comet
941 Morphological: Rectangle, Square, Diamond, Disk, Plus
942 Distance: Chebyshev, Manhatten, Knight, Euclidean
943 And both old and new (rectangular) user defined kernel specifications
944 including the use of 'nan' to represent elements which are not part
945 of the kernel definition. List built-in kernel types use "-list kernel"
946 * Added -morphology {method}[:{iteration}] {kernel_string}
947 Initial methods includes no only the basic morphology methods: Dilate,
948 Erode, Open, Close; and a pixel color preserving 'Intensity' version, but
949 also the special methods: Convolve, and Distance. Of course the
950 appropriate kernel should be provided for each specific method.
951
9522010-01-01 6.5.9-0 Cristy <quetzlzacatenango@image...>
953 * Add OpenCL-enabled filter (e.g. convert image.png -process
954 "convolve '-1, -1, -1, -1, 9, -1, -1, -1, -1'" image.jpg).
955 * Added StringTo...() processing functions
956

1192 * Replace color blending in DrawGradientImage() to use Composite Blend.
1193 this makes Gradients handle transparency correctly!
1194
11952009-07-28 6.5.4-7 Cristy <quetzlzacatenango@image...>
1196 * The -thumbnail option no longer removes color profiles (reference
1197 http://www.imagemagick.org/discourse-server/viewtopic.php?f=2&t=14312).

12142009-07-21 6.5.4-4 Cristy <quetzlzacatenango@image...>
1215 * Update autoconf support files.
1216 * More than one -dispose setting overwrote previous settings (reference
1217 http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=14252).
1218 * Don't use JPEG's color reduction algorithm for less than 8 colors.
1219
12202009-07-13 6.5.4-3 Anthony Thyssen <A.Thyssen@griffith...>
1221 * Final testing and bug fixes for all mathematical compose methods
1222 Including non-overlapping regions bugs found in in operators Divide,
1223 ColorDodge, VividLight. And the handling of transparency to follow
1224 standard 'Over' Blending in Divide. Only math methods not looked at are
1225 the addition methods Plus, Add, Minus, and Subtract, which do not follow
1226 normal 'Over' alpha blending behaviour, for the purposes of mask handling.
1227
12282009-07-12 6.5.4-3 Anthony Thyssen <A.Thyssen@griffith...>
1229 * Addition of user definable 'Mathematics' compose method
1230 -compose Mathematics -set option:compose:args A,B,C,D -composite
1231 Will implement the formula f(Sc,Dc) = A*Sc*Dc + B*Sc + C*Dc + D
1232 this lets you implement most smooth polynomial compose methods.
1233 (requested by Fred WienHaus)
1234
12352009-07-11 6.5.4-3 Anthony Thyssen <A.Thyssen@griffith...>
1236 * Finished the recoding of Composite methods to allow easier debugging
1237 and faster access.
1238 * Added PegtopLight compose method as an alternative simpler Softlight
1239 alternative. See notes and comparision to SoftLight in...
1240 http://www.pegtop.net/delphi/articles/blendmodes/softlight.htm
1241 * From the notes on Photoshop blend modes at
1242 http://www.simplefilter.de/en/basics/mixmods.html
1243 Added extra composition modes:
1244 VividLight, PinLight, LinearBurn, LinearDodge
1245 NOTE: 'LinearBurn' the same as 'Plus' but with the normal 'Over' blending.
1246
12472009-07-10 6.5.4-3 Anthony Thyssen <A.Thyssen@griffith...>
1248 * Re-coding of Composite methods HardLight, SoftLight, Overlay, LinearLight,
1249 ColorBurn, ColorDodge, Multiply, Screen to make it more readable, easier
1250 to debug, and directly comparable to SVG specifications.
1251 * Specifications changed for SoftLight, ColorBurn, ColorDodge
1252 Though only SoftLight changed to significantly.
1253 * However implementation errors were found for ColorBurn, LinearLight
1254

1262 * Support breaks in Chinese characters which traditionally do not include
1263 spaces.
1264 * Don't process directories as filenames when using wildcard paths
1265 (i.e. logo[1]/png).
1266
12672009-07-01 6.5.4-2 Cristy <quetzlzacatenango@image...>
1268 * Can't bit shift a float.

1289 * Clone pixel cache when cloning image to prevent RMagick semaphore lock.
1290 * Set compare similarity image to NULL to prevent double free.
1291
12922009-06-16 6.5.3-8 Cristy <quetzlzacatenango@image...>
1293 * Set camera formats to require a seekable stream.
1294 * Do not let display program image window exceed the screen size.
1295
12962009-06-14 6.5.3-7 Cristy <quetzlzacatenango@image...>

1298
12992009-06-14 6.5.3-7 Anthony Thyssen <A.Thyssen@griffith...>
1300 * Cleanup of compose 'displace' of old useless code that is not used.
1301 * Implement a compose 'distort' mapping method,
1302 This is basically exactly like 'displace' but relative to a fixed point
1303 which may be user supplied as +X+Y
1304 * Default scaling to width/2 and height/2 of overlay (100% scale)
1305 with a distortion 'center' to the middle of the overlay image
1306 * If a '%' flag given scale displacement relative to image size
cristya97426c2011-02-04 01:41:27 +00001307 * If a '!' flag given make scale and center relative to 'background' image
cristy2bc0ef72010-02-02 01:38:51 +00001308 instead of the overlay map.
1309 * If no 'height' scale given, use the X scale.
1310
13112009-06-13 6.5.3-6 Anthony Thyssen <A.Thyssen@griffith...>
1312 * Fixed bug for compose methods, Hue, Saturate, Luminize
1313
13142009-06-11 6.5.3-6 Cristy <quetzlzacatenango@image...>
1315 * Report the correct transparent pixel values in the display program
1316 magnify windows.
1317 * Do not advance when finalizing image settings in the mogrify program.
1318
13192009-06-11 6.5.3-5 Anthony Thyssen <A.Thyssen@griffith...>
1320 * Fixed "convert" to merge the third 'mask' image into the 'source' image
1321 for correct handling of 2 dimensional -compose "displace".
1322 * Fixed PerlMagick Composite() for the same thing.
1323 * Modified compose "Displace" so displacement image's alpha channel can be
1324 used to mask the transparency of the overlay area.
1325
13262009-06-07 6.5.3-4 Cristy <quetzlzacatenango@image...>
1327 * Added the HALD image Color LUT, and a no-op HALD: image generator.

1329
13302009-06-07 6.5.3-4 Anthony Thyssen <A.Thyssen@griffith...>
1331 * Changed CompositeImageChannel() so that extra compose arguments are
1332 now passed in the ImageArtifact "compose:args". This can be assigned to
1333 images using -set "option:compose:args" 'args' where args are defined
1334 using 'geometry' style or 'comma separated numbers'.
1335 * Declared the special flag needed for Composite Tiling as the ImageArtifact
1336 "compose:outside-overlay".
1337 * Documentation update for CompositeImageChannel() in Core Library to
1338 reflect these changes.
1339 * Documentation update for DistortImage() in Core Library with the extra
1340 ImageArtifact controls it can use.
1341 * Bug correction in normalization of GetOptimalKernelWidth2D() of gem.c
1342
13432009-06-06 6.5.3-3 Anthony Thyssen <A.Thyssen@griffith...>
1344 * Documentation update for CompositeImageChannel() in Core Library.
1345 This adds the information on how extra compose arguments needed for
1346 specific compose methods are actually passed to the library function.
1347 Compose methods such as Blend, Dissolve and Displace.

14052009-05-06 6.5.2-3 Glenn Randers-Pehrson <glennrp@image...>
1406 * Progress on "-define png:bit-depth=value" and "-define png:color-type=value"
1407 It is now able to write an opaque black-and-white image in any of the 15
1408 valid combinations of PNG color-type and bit-depth.
1409 * Fixed a regression with writing sub-8-bit grayscale PNGs.
1410
14112009-05-06 6.5.2-2 Chris Madison <madisonblu@gmail...>

cristya97426c2011-02-04 01:41:27 +00001415 * Accept file lists on the command line (e.g. echo "rose: rose.png" |
cristy2bc0ef72010-02-02 01:38:51 +00001416 convert @- ...).
1417 * Duplicate line in tiff.c breaking read of zip compressed tif (reference
1418 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=13688).
1419 * Support policies to permit or deny any coder, delegate, filter, or file
1420 path (see policy.xml).
1421
14222009-05-02 6.5.2-0 Chris Madison <madisonblu@gmail...>
1423 * The mogrify -crop option returns multiple images if an x/y offset is not
1424 specified (e.g. -crop 100x100).
1425 * Generate a proper file path for -path @filelist.txt (reference
1426 http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=13671).
1427
14282009-05-01 6.5.2-0 Glenn Randers-Pehrson <glennrp@image...>
1429 * Accept "-define png:bit-depth=value" and "-define png:color-type=value"
1430 options. This is work-in-progress with the objective of being able to
1431 precisely specify the type of PNG file to be written. The previously-used
1432 internal attribute "png:bit-depth" that was used to communicate between
1433 the PNG writer and the JNG writer is changed to "png:bit-depth-written".
1434 This feature needs testing. It is important to note that this feature
1435 cannot be used to force the PNG to use a bit-depth or color-type that
1436 does not losslessly represent the image. You can, however, cause
1437 the writer to use a larger depth or to use the RGB colorspace when
1438 grayscale or indexed would have been sufficent.
1439
14402009-05-01 6.5.1-10 Anthony Thyssen <A.Thyssen@griffith...>
1441 * Fixed the Rmin usage in Depolar and Polar distortions

1475
14762009-04-21 6.5.1-4 Glenn Randers-Pehrson <glennrp@image...>
1477 * Sometimes the PNG8: format would produce 1-, 2-, or 4-bit PNG datastreams.
1478 Now it always produces 8-bit datastreams as users probably expect.
1479
14802009-04-21 6.5.1-4 Glenn Randers-Pehrson <glennrp@image...>

1504 * The "Bilinear" distort is temporarily obsoleted but will eventually
1505 be added as a "BilinearReverse" and "BilinearForward" combination
1506 mapping though a unit square.
1507 * Sparse Gradient internally uses "BilinearReverse" for its "Bilinear"
1508 gradient function as that method is the direct use of such equations.
1509
15102009-04-01 6.5.1-1 Cristy <quetzlzacatenango@image...>

2265 * Updated to the latest autoconf/automake/libtool scripts.
2266 * Default to HSL colorspace when modulating (reference
2267 http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=11073).
2268 * The -regard-warnings option properly returns a program status of 1 if and
2269 only if a warning or error exception is thrown.
2270 * Report 'no clip path defined' exception for -clip-path option (reference
2271 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=11098).
2272
22732008-04-16 6.4.0-8 Cristy <quetzlzacatenango@image...>
2274 * Distinquish between pre and post processing of image list options.
2275 * Return MagickTrue if InvokeDynamicImageFilter() does not generate an
2276 exception (reference
2277 http://www.imagemagick.org/discourse-server/viewtopic.php?f=2&t=11065).
2278
22792008-04-16 6.4.0-7 Glenn Randers-Pehrson <glennrp@image...>
2280 * Instead of masking the PNG tRNS values when reducing from 16-bit,
2281 set image->matte to MagickFalse and emit a warning. This will produce
2282 behavior similar to that of libpng-1.2.27 (and libpng-1.2.19 and earlier).
2283
22842008-04-12 6.4.0-7 Cristy <quetzlzacatenango@image...>
2285 * Fix fault for animate -window root image.gif.

2295 the PNG specification, instead of scaling them.
2296
22972008-04-09 6.4.0-5 Glenn Randers-Pehrson <glennrp@image...>
2298 * Revised png.c to avoid saving unknown chunk types that will never
2299 be used later. This prevents the vulnerability described in
2300 CVE-2008-1382, with respect to all unknown chunks except vpAg.
2301 To handle an invalid, zero-length vpAg chunk properly will require
2302 libpng-1.2.27 or later.
2303

23122008-03-26 6.4.0-1 Cristy <quetzlzacatenango@image...>
2313 * Rewrote patch so that writing pyramid TIFF images no longer fails if a
2314 tile size is specified (e.g. ptif:image.tif[128x128]).
2315 * Malformed use of caption no longer consumes memory (reference
2316 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=10914).

2319
23202008-03-21 6.4.0-0 Cristy <quetzlzacatenango@image...>
2321 * SpreadImage() no longer introduces noise into the resulting image (reference
2322 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=10892).
2323 * Properly handle min-is-white TIFF gray scale images.
2324 * Use CompositeImage() instead of DrawAffineImage() if the affine expansion
2325 factor is 1.0.

2340 * Patch mpeg:encode delegate to properly produce an MPEG image sequence.
2341
23422008-03-11 6.3.9-6 Cristy <quetzlzacatenango@image...>
2343 * Support both GTK and CAIRO interfaces to RSVG (reference
2344 ttp://www.imagemagick.org/discourse-server/viewtopic.php?f=2&t=10802).
2345 * Display colormapped PNG images with alpha properly (reference
2346 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=10819).
2347
23482008-03-09 6.3.9-5 Cristy <quetzlzacatenango@image...>
2349 * Define inline to _magickcore_inline (to satisfy HP's aCC compiler).

2364 http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=10715).
2365 * Fix so image.quantize(true) returns error as expected (reference
2366 http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=10735).
2367

2402 http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=10536).
2403 * Read EXIF data in TIFF images; writing is pending until we can figure out
2404 how to use the libtiff delegate library to write EXIF data.
2405
24062008-01-24 6.3.8-2 Cristy <quetzlzacatenango@image...>
2407 * Add support for liquid rescaling (e.g. -liquid-rescale).
2408 * Support a ^ meta character in an image geometry (.e.g
2409 convert 640x480.png -resize 240^ returns a 320x240 result).
2410
24112008-01-20 6.3.8-1 Cristy <quetzlzacatenango@image...>
2412 * Fix transient bug where "identify -format '%w;%[exif:Model]'" failed to
2413 return camera model number.
2414
24152008-01-14 6.3.8-0 Cristy <quetzlzacatenango@image...>
2416 * Monochome EPS3 images are no longer corrupt (reference
2417 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=10422).
2418 * Eliminate memory corruption with broken PICT image (reference
2419 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=10447).
2420 * Return a Grayscale colorspace for grayscale DPX image (previously
2421 returned Log colorspace).
2422 * Fix -g option for PCL6 support (reference
2423 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=10462).
2424
24252008-01-08 6.3.7-10 Cristy <quetzlzacatenango@image...>
2426 * Only read ICON alpha mask if BPP is <= 16.
2427 * Add support for +opaque and +transparent (requested by Anthony).
2428 * Throw an exception *before* we call wmf_api_destroy() (reference
2429 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=10420).
2430
24312008-01-01 6.3.7-9 Cristy <quetzlzacatenango@image...>
2432 * Use explicit format specifier to render transparent Adobe Illustrator
2433 files (i.e. convert ai:image.ai image.png).
2434 * Set RSVG base URI (patch provided by tsdineen).
2435
24362007-12-20 6.3.7-7 Cristy <quetzlzacatenango@image...>

24412007-12-13 6.3.7-5 Cristy <quetzlzacatenango@image...>
2442 * Added an exception reason to BlobToImage() in the event an image has no
2443 magic number and neither the image magick or filename is set.
2444 * Do not pass PhotoYCC data thru gamma-corrected lookup-table.
2445 * Fix bug in GetEXIFProperty() (reference

2449 * Adding comments to your image is now possible with the display program.
2450
24512007-12-09 6.3.7-3 Anthony <anthony@griffith...>
2452 * Adjusted -clut multiplyer for correct handling of
2453 "-interpolation Integer" in color lookup.
2454
24552007-12-01 6.3.7-3 Cristy <quetzlzacatenango@image...>

2465 * Colormapped multi-image PDF's are no longer corrupt (reference
2466 https://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=10258).
2467
24682007-11-27 6.3.7-2 Anthony <anthony@griffith...>
2469 * Finalisation of new resize filters, "Lagrange" self-windowing filter
2470 now adjusts automatically with different support window size.
2471 * Added "Bohman" (another 2'rd order cosine function) and "Bartlett"
2472 (triangluar) resize windowing filters.
2473 * Adjusted -clut to use a grayscale image (with no alpha) to select colors
2474 from the Lookup Table image.
2475
24762007-11-26 6.3.7-2 Cristy <quetzlzacatenango@image...>

2498 set the image alpha channel.
2499 * Patch for Scanalytics IPLab image format for non 8-bit images
2500 (contributed by Sean Burke).
2501
25022007-11-04 6.3.6-8 Chris Madison <madisonblu@hotma...>
2503 * Remove ctrl-M characters on in various source files.
2504 * Fix signature for Magick++ averageImages() regression tests for HDRI.
2505 * Only invoke PerlMagick x11 regression test if DISPLAY variable is set.
2506
25072007-11-03 6.3.6-7 Chris Madison <madisonblu@hotma...>
2508 * MAGICK_ERX_SRCS should be MAGICK_EXR_SRCS in coders/Makefile.am.
2509
25102007-11-02 6.3.6-6 Cristy <quetzlzacatenango@image...>
2511 * Upgrade to FPX version libfpx-1.2.0.14 (reference
2512 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=10041).
2513 * Modules are searched first in the directories specified by the environment
2514 variables, and then -- if the desired module is not found -- in the
2515 compiled-in path. (reference
2516 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=10039).
2517
25182007-11-01 6.3.6-5 Cristy <quetzlzacatenango@image...>
2519 * Update FPX regression test reference images.
2520 * Fixed Magick++ compile error for Sun Studio 10 compiler.
2521
25222007-10-25 6.3.6-4 Cristy <quetzlzacatenango@image...>
2523 * The -equalize option now respects the -channel option.
2524
25252007-10-23 6.3.6-4 Anthony <anthony@griffith...>
2526 * Additional Filters: Welsh, Parzen, Lagrangian
2527 * Addition of Cubic filter B,C controls
2528 * 'verbose' filter plotting output using -define "filter:verbose"
2529
25302007-10-20 6.3.6-3 Anthony <anthony@griffith...>
2531 * Further expandsion and handling of filters with expert options.
2532 -filter selects from a table of standard filter settings, while
2533 expert options allow complete selection of filter, windowing, support
2534 and blurring options. Includes automatic switch from Sinc to Bessel
2535 for operators using 2 dimentional cylindrical filter, rather than
2536 two pass 1 dimentional orthogonal filters.
2537
25382007-10-14 6.3.6-3 Cristy <quetzlzacatenango@image...>
2539 * Obsolete -support (set filter blur factor)
2540 * Expandsion to add -set/define filter options
2541
25422007-10-12 6.3.6-2 Anthony <anthony@griffith...>
2543 * Least Squares coordinate handling added for -distort methods Affine,
2544 Perspective, Bilinear. This allows for more than the minimal number of
2545 coordinates to be used to 'fit' a distortion function to an image.
2546 This addition will allow the use of image registration to generate
2547 panarama overviews and better geographical coordinate correction.
2548 * Cosolidated the simular methods FlattenImage() and MosaicImage()
2549 into a new layers function MergeImageLayers() method, adding 'flatten'
2550 and 'mosaic' layer methods.
2551 * Addition of another simular layers method 'merge' which 'unlocks' the
2552 normal flatten/mosaic layer merger from the origin, The resulting image
2553 will have a virtual canvas of minimal size with an offset. Also images
2554 with negative offsets will not be clipped by the 'merge' form of the
2555 command. This was created for better layering of distorted images, such
2556 as panarama overlays.
2557 * Bug fix in handling transparency for EWA resampling.
2558 * Access to Resize Filter Functions from resize.c (for resample.c)
2559 with posible future filter sources... Acquire/Destory/Call ResizeFilter()
2560 * All resize filters added to resampling, but filter handling is incomplete.
2561
25622007-10-05 6.3.6-2 Cristy <quetzlzacatenango@image...>
2563 * The box filter no longer produces a black grid when resizing an image
2564 under Mac OS X.
2565 * Respect cropbox for PDF with a subimage specification (e.g.
2566 image.pdf[1-3]).
2567 * Detect proper PDF bounding box when offsets are negative.
2568
25692007-10-02 6.3.6-1 Cristy <quetzlzacatenango@image...>
2570 * Speed up the Fx interpreter.
2571 * Use ULL not ui64 for MinGW 64-bit constants.
2572 * Call SyncCacheView() instead of SyncImagePixels() in WaveImage().
2573 * Close all references to a pixel cache on disk before removing the temporary
2574 file as required under Windows.
2575
25762007-09-29 6.3.6-0 Anthony <anthony@griffith...>
2577 * Added Scaling 'derivitives' to -distort Arc, so image arcing is now
2578 sharp and clear as you approach the center of the distort.
2579 * Added " -set option:distort:viewport 'geometry' " special option
2580 that can be used to override the output image size and offset.
2581 * Fixed experimental use of -filter and -support in Resampling (more later).
2582 * Changed order for coordinate arguments in -distort (for later leastsq
2583 multiple coordinate distortion function fitting)
2584
25852007-09-22 6.3.6-0 Cristy <quetzlzacatenango@image...>
2586 * Check the API version and quantum depth before loading a coder module or
2587 image filter (reference
2588 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=9780).
2589 * Add exception to the image filter signature.
2590 * Get the execution path under Mac OS X.
2591 * TIFFTAG_STRIPBYTECOUNTS requires a uint32 pointer (magick/compress.c).
2592 * Fixed memory leak in CloneString() (reference
2593 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=9763).
2594 * Set S_IRUSR | S_IWUSR | S_IRGRP mode when writing a file in
2595 CopyDelegateFile().
2596
25972007-09-18 6.3.5-9 Anthony <anthony@griffith...>
2598 * Bug fix for +distort in Perspective, also effected PerspectiveProjection
2599
26002007-09-17 6.3.5-10 Cristy <quetzlzacatenango@image...>
2601 * Replace all InterpolatePixelColor() calls to use the ResamplePixelColor()
2602 method instead.
2603 * Map the display program pan icon window for each oversized image.
2604 * The ufraw delegate does not like quotes around the output filename.
2605 * Adjust the sensitivity of a few PerlMagick tests to pass the validation on
2606 a 64-bit FreeBSD system.
2607 * The -level option now works properly for colormapped images.
2608 * Allow Extrapolated blending of images using -blend
2609 http://netpbm.sourceforge.net/doc/extendedopacity.html
2610
26112007-09-12 6.3.5-9 Anthony <anthony@griffith...>
2612 * Major Addition, Area Resampling Functions, (scaled interpolation)
2613 for pixel lookup in Distortion functions. This improves the look in
2614 areas of minification enormousally, especially in situations of infinite
2615 tiling and horizon views. All virtual pixel methods have been handled
2616 to minimise computation time involved with area resampling. To use the
2617 new function distortions need to be able to determine scaling vectors
2618 (distortion function derivitives) for correct working. All
2619 -distort methods, except Arc, uses scaled area resampling.
2620 * Improvements to perspective distort method, to include the correct
2621 differentation between the 'ground' on which the image lies, and the
2622 'sky', the color of which can be set using the -mattecolor setting
2623 (as the distortion invalid pixel color). Background color is retains
2624 for surrounding ground areas. The horizon is also correct anti-aliased
2625 and transparent colors are also allowed, allowing you to add backdrops
2626 of gradients and patterns.
2627
26282007-09-04 6.3.5-9 Cristy <quetzlzacatenango@image...>
