2 * Ignore PS bounding box offsets if -page is set.
cristyaabc95d2010-10-16 01:12:47 +00003 * Use #pragma omp master for dumping single threaded debugging information
4 (single caused a fault).
cristy9fe8cd72010-10-19 01:24:07 +00005 * Add support for -evaluate exp.

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

15 * Patch for DrawableRotation() and DrawableTranslation() (reference
16 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17246).
cristy56dd2cd2010-10-11 00:45:14 +000017 * The webp format requires the webpconv delegate program (experimental).

20 * Replaced "Robidoux" with Cubic 'Keys' filter that is near equivelent to
21 the previous sharped "Lanczos2D" filter. (C=0.31089212245300069)
anthonyf5e76ef2010-10-12 01:22:01 +000022 This also is very similer to a Mitchell filter but specifically designed
23 for EWA use and is the new default filter for Distorting Images.
anthonye5f06452010-10-12 05:48:17 +000024 * Original sharpened Lanczos2D filter now called "Lanczos2Dsharp"

anthony853d6972010-10-08 06:01:31 +000030 * Added new filter 'Lanczos2D' a 2-lobe Lanczos as defined by
31 Andreas Gustafsson in his thesis "Interactive Image Warping" (page 24)
32 http://www.gson.org/thesis/warping-thesis.pdf
anthonyd5fae5d2010-10-10 03:59:06 +000033 * Added filter "Robidoux" which is a slightly sharpened version of the
anthony02b4cb42010-10-10 04:54:35 +000034 "Lanczos2D" filter (blur=0.958033808) specifically designed to be less
35 'blurry' for horizontal and vertical lines in no-op distortions.

372010-10-05 6.6.4-10 Cristy <quetzlzacatenango@image...>
38 * Add support for "pattern:vertical2" and "pattern:horizontal2".
cristy99123912010-10-05 11:29:37 +000039 * Add support for "pattern:vertical3" and "pattern:horizontal3".
cristy4484e332010-10-08 23:46:21 +000040 * Properly handle PSD layers with negative offsets.

43 * Fix memory assertion with --enable-embeddable (reference
44 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17201).
cristy33503f52010-10-04 17:32:27 +000045 * Don't permit access to pixels when pinging an image (reference
46 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17194).

anthony61b5ddd2010-10-05 02:33:31 +000049 * Added sqrt(2) bluring default for Gaussian Filter if used as
50 a Cylindrical EWA filter. This resulted removing the last aliasing
51 issue that was present in tests for Gaussian EWA resampling. Of course
52 it is still a very blury filter for default use in EWA.
anthony10b8bc82010-10-02 12:48:46 +000053 * Adjusted Variable Mapping Blur Composition so user arguments actual
54 relate properly to the sigma of the blur for a maximum mapping value.
anthony61b5ddd2010-10-05 02:33:31 +000055 * Fix horizon anti-alising for output-scaled perspective distortions.
56 * 'Bessel' filter is now offically and more accuritally named 'Jinc'
anthony48f77622010-10-03 14:32:31 +000057 however 'Bessel' while not visible as a filter option can still be used
58 as an internal alias for 'Jinc'.

61 * Chantal Racette double checked the bounding parallelogram computation
62 in resample.c (and I tightened the comments).

anthony61b5ddd2010-10-05 02:33:31 +000072 * Simplified the ClampUpAxes code, the use of its outputs, its comments,
73 and credited Craig DeForest for the "clamp singular values" idea.
nicolasc2d28f02010-09-27 18:56:15 +000074 * No reason to have "insane" precision Sinc in resize.c: Use
75 the 1.2e-12 max. abs. relative error version for Q64 as well as Q32.

78 * Replace the blurry "High Quality EWA" technique with a 'Clamped EWA'
nicolasb05c3df2010-09-27 15:58:42 +000079 for Distort Resampling. This makes -distort a whole lot nicer
anthonyc7b82f22010-09-27 10:42:29 +000080 and allows for the use of better cylindrical filters.

83 * Fix Point filter for ResizeImage() caused by support limiting the
84 Box weighting function.
85
nicolasb05c3df2010-09-27 15:58:42 +0000862010-09-26 6.6.4-6 Cristy <quetzlzacatenango@image...>

nicolas92375332010-09-21 00:32:38 +000099 * Modified "magick/resize.c" so that MagickPIL is a MagickRealType number.
nicolas94a41852010-09-21 14:35:09 +0000100 Some computations were needlessly done in long double precision because
101 PIL forced an automatic upcast wherever it appeared. Changed its name to
nicolasb05c3df2010-09-27 15:58:42 +0000102 MagickREALTYPEPI. <- This was later reverted back to MagickPIL.
nicolas94a41852010-09-21 14:35:09 +0000103 * Modified "magick/resize.c" so that Bohman uses one trig call + one sqrt
104 call instead of two trig calls.

anthony490ab032010-09-20 00:02:08 +0000107 * modified "magick/resample.c" to allow use of either EWA or HQEWA (default)
anthony5aa65212010-09-20 04:20:28 +0000108 * Removed LanczosFast from supported filters (SincFast*SincFast is faster)

111 * If IPTC profile is not embedded in an 8bim resource, declare it IPTC
112 rather than 8BIM.
cristy63054742010-09-20 12:42:28 +0000113 * Support %[version] and %[copyright].
cristy0158a4b2010-09-20 13:59:45 +0000114 * Improve performance of the pixel cache.

120 * IPTC profile not always wrapped properly inside an 8BIM profile.
anthony165bd162010-09-20 01:06:26 +0000121 * TIFF tile geometry must be divisible by 16.

glennrpf5e546d2010-09-18 19:12:38 +0000124 * Rename of SincPolynomial to SincFast for easier user understanding
anthonyba5a7c32010-09-15 02:42:25 +0000125 * Ditto for LanczosChebyshev to LanzcosFast
126
anthony5708fc62010-09-14 13:52:50 +00001272010-09-14 6.6.4-2 Anthony Thyssen <A.Thyssen@griffith...>
128 * Switch default resize filters to using the faster SincPolynomial
glennrpf5e546d2010-09-18 19:12:38 +0000129 filter by default internally. However 'Sinc' will still use the
anthony5708fc62010-09-14 13:52:50 +0000130 Trigonometric function, and can be used to assign the trig version
131 of Sinc() to filters using the filter expert options.
anthony165bd162010-09-20 01:06:26 +0000132 * The default filter for 'distort' was found to be a very blurry inaccurate
133 filter function. It was removed and replaced with a correct Gaussian
134 filter (as used by resize)
anthony5708fc62010-09-14 13:52:50 +0000135 * Added a switch so that "-interpolate filter" will force the use of
136 a cylindrical filter for ALL pixels in distorted images. That is you can
glennrp705a1ef2010-09-16 11:31:26 +0000137 use that switch to use a cylindrical filter even for images that are
anthony165bd162010-09-20 01:06:26 +0000138 being enlarged by the distortion. However EWA is still currently using
139 a fixed 2.0 sampling radius. This switch complements the use of "-filter
140 point" which turns off EWA filters in favor of interpolation for all
141 pixels in a distorted image. BOTH switches should not be used together.
anthony5708fc62010-09-14 13:52:50 +0000142 * A bug in the support radius of the EWA resampling function was found,
143 now that correctly defined resize filters are being used. Suddenly Normal
144 Gaussian distortions are not so blurry, and tests with distortions of
145 the 'Rings' image show extremely good and clear results, with only minimal
146 blurring. The filter 'blur' expert option can be used to adjust this
147 further.
148
glennrp705a1ef2010-09-16 11:31:26 +0000149 The above represents a major improvement forward in the quality of the
anthony165bd162010-09-20 01:06:26 +0000150 image distortion operator. But near-unity distortions (no scaling) are
151 still overly blurry.

anthonyb6d08c52010-09-13 01:17:04 +0000160 * Added the Nicolas Robidoux and Chantal Racette Lanczos resize filter
glennrpf5e546d2010-09-18 19:12:38 +0000161 function as "LanczosChebyshev" as faster alternative to Lanczos.
anthony9d7245a2010-09-07 10:18:56 +0000162 * Re-code Nicolas Robidoux and Chantal Racette Polynomial Approximation of
163 the Sinc Trigonometric resize filter, as a proper filter to allow
164 direct comparision and speed testing of the filter.
anthony019e8482010-09-10 01:21:43 +0000165 * Expanded the "-set option:filter:verbose 1" output, so as to also include
166 the actual functions and other values that were used to create the filter.

448 * Rename of "Add" and "Subtract" compositions to "ModulusAdd" and
449 "ModulusSubtract" for more clarity of there functions. Old names
450 will continue to work as expected.
anthony320be8b2010-05-05 06:16:16 +0000451 * Fix "Minus", "ModulusAdd", and "ModulusSubtract" to follow
anthonyc5d68fe2010-05-05 05:27:54 +0000452 normal SVG 'Over' blending specifications, (see next for override)
anthony320be8b2010-05-05 06:16:16 +0000453 Note that this does NOT include the "Plus" composition method which has
glennrpa3adfd92010-05-14 18:12:46 +0000454 SVG definition for it to use a 'Plus' blending rather than 'Over' blending.
anthony320be8b2010-05-05 06:16:16 +0000455
456 * By default mathematical compositions work as per SVG definition. That is
glennrpa3adfd92010-05-14 18:12:46 +0000457 the results are synchronized with 'Over' alpha-blending (except "Plus"
anthony320be8b2010-05-05 06:16:16 +0000458 which uses 'plus' alpha-blending).
459
460 By removing the default 'sync' flag from the -channel setting however
glennrpa3adfd92010-05-14 18:12:46 +0000461 Break this inter-channel synchronization and do the mathematical operations
anthony320be8b2010-05-05 06:16:16 +0000462 only on the individual channels as specified by the -channel setting.
463 That is do 'channel' math rather than 'SVG' composition.
464
465 With this change you can then use mathematical composition methods on
466 individual channels or even with the alpha channel of images.

648 * correct use of a 'reflected kernel' for 'Convolve' 'Dilate' and
649 'Distance' Morphology primatives. This does not have a performance hit,
650 though is only truely applicable when the kernel is asymmetric. Note that
651 'Erode' does not use a 'reflected' kernel, so that 'Open' and 'Close'
652 operations work properly. This 'reflected usage is defined by online
653 morphology lecture notes (Google for "EECE Binary Morphology")
654 * Added convolve kernel scaling setting "-set option:convolve:scale N"
655 If undefined morphology convolve does not do any scaling or normalization
656 of the convolution kernel. A value of 0.0 causes normalization for both
657 zero and non-zero (added weights) kernel types.
658
6592010-01-15 6.5.9-1 Cristy <quetzlzacatenango@image...>

683 and other Morphological methods. New Kernels currently include..
684 Convolution: Gaussian, Blur, Comet
685 Morphological: Rectangle, Square, Diamond, Disk, Plus
686 Distance: Chebyshev, Manhatten, Knight, Euclidean
687 And both old and new (rectangular) user defined kernel specifications
688 including the use of 'nan' to represent elements which are not part
689 of the kernel definition. List built-in kernel types use "-list kernel"
690 * Added -morphology {method}[:{iteration}] {kernel_string}
691 Initial methods includes no only the basic morphology methods: Dilate,
692 Erode, Open, Close; and a pixel color preserving 'Intensity' version, but
693 also the special methods: Convolve, and Distance. Of course the
694 appropriate kernel should be provided for each specific method.
695
6962010-01-01 6.5.9-0 Cristy <quetzlzacatenango@image...>

10432009-06-14 6.5.3-7 Anthony Thyssen <A.Thyssen@griffith...>
1044 * Cleanup of compose 'displace' of old useless code that is not used.
1045 * Implement a compose 'distort' mapping method,
1046 This is basically exactly like 'displace' but relative to a fixed point
1047 which may be user supplied as +X+Y
1048 * Default scaling to width/2 and height/2 of overlay (100% scale)
1049 with a distortion 'center' to the middle of the overlay image
1050 * If a '%' flag given scale displacement relative to image size
1051 * If a '!' flag given make scale and center relative to 'background' image
1052 instead of the overlay map.
1053 * If no 'height' scale given, use the X scale.

1062
10632009-06-11 6.5.3-5 Anthony Thyssen <A.Thyssen@griffith...>
1064 * Fixed "convert" to merge the third 'mask' image into the 'source' image
1065 for correct handling of 2 dimensional -compose "displace".
1066 * Fixed PerlMagick Composite() for the same thing.
1067 * Modified compose "Displace" so displacement image's alpha channel can be
1068 used to mask the transparency of the overlay area.
1069
10702009-06-07 6.5.3-4 Cristy <quetzlzacatenango@image...>
1071 * Added the HALD image Color LUT, and a no-op HALD: image generator.

1073
10742009-06-07 6.5.3-4 Anthony Thyssen <A.Thyssen@griffith...>
1075 * Changed CompositeImageChannel() so that extra compose arguments are
1076 now passed in the ImageArtifact "compose:args". This can be assigned to
1077 images using -set "option:compose:args" 'args' where args are defined
1078 using 'geometry' style or 'comma separated numbers'.
1079 * Declared the special flag needed for Composite Tiling as the ImageArtifact
1080 "compose:outside-overlay".
1081 * Documentation update for CompositeImageChannel() in Core Library to
1082 reflect these changes.
1083 * Documentation update for DistortImage() in Core Library with the extra
1084 ImageArtifact controls it can use.
1085 * Bug correction in normalization of GetOptimalKernelWidth2D() of gem.c
1086
10872009-06-06 6.5.3-3 Anthony Thyssen <A.Thyssen@griffith...>

1148
11492009-05-06 6.5.2-3 Glenn Randers-Pehrson <glennrp@image...>
1150 * Progress on "-define png:bit-depth=value" and "-define png:color-type=value"
1151 It is now able to write an opaque black-and-white image in any of the 15
1152 valid combinations of PNG color-type and bit-depth.
1153 * Fixed a regression with writing sub-8-bit grayscale PNGs.
1154
11552009-05-06 6.5.2-2 Chris Madison <madisonblu@gmail...>
1156 * Create 8-bit TIFF images if -depth is set to 8 and HDRI-enable ImageMagick.
1157
11582009-05-04 6.5.2-1 Chris Madison <madisonblu@gmail...>
1159 * Accept file lists on the command line (e.g. echo "rose: rose.png" |
1160 convert @- ...).
1161 * Duplicate line in tiff.c breaking read of zip compressed tif (reference
1162 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=13688).
1163 * Support policies to permit or deny any coder, delegate, filter, or file
1164 path (see policy.xml).
1165
11662009-05-02 6.5.2-0 Chris Madison <madisonblu@gmail...>
1167 * The mogrify -crop option returns multiple images if an x/y offset is not
1168 specified (e.g. -crop 100x100).
1169 * Generate a proper file path for -path @filelist.txt (reference
1170 http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=13671).
1171
11722009-05-01 6.5.2-0 Glenn Randers-Pehrson <glennrp@image...>
1173 * Accept "-define png:bit-depth=value" and "-define png:color-type=value"
1174 options. This is work-in-progress with the objective of being able to
1175 precisely specify the type of PNG file to be written. The previously-used
1176 internal attribute "png:bit-depth" that was used to communicate between
1177 the PNG writer and the JNG writer is changed to "png:bit-depth-written".
1178 This feature needs testing. It is important to note that this feature
1179 cannot be used to force the PNG to use a bit-depth or color-type that
1180 does not losslessly represent the image. You can, however, cause
1181 the writer to use a larger depth or to use the RGB colorspace when
1182 grayscale or indexed would have been sufficent.
1183
11842009-05-01 6.5.1-10 Anthony Thyssen <A.Thyssen@griffith...>
1185 * Fixed the Rmin usage in Depolar and Polar distortions

1219
12202009-04-21 6.5.1-4 Glenn Randers-Pehrson <glennrp@image...>
1221 * Sometimes the PNG8: format would produce 1-, 2-, or 4-bit PNG datastreams.

1250 mapping though a unit square.
1251 * Sparse Gradient internally uses "BilinearReverse" for its "Bilinear"
1252 gradient function as that method is the direct use of such equations.

13552009-02-22 6.4.9-7 Rick Mabry <rick.mabry@anony...>
1356 * Changes have been made to scores of the files that generate the
1357 documentation. The most noticeable cosmetic changes are to the command-line
1358 examples and command-line snippets, which now have a new look: dark blue
1359 boxes with white/yellow text to indicate sample input/output. Inclusion of
1360 current version and release dates in appropriate places are now
1361 automatically generated. Also, many changes have been made to begin to
1362 bring the pages into strict W3C compliance with respect to both HTML and
1363 CSS.
1364
13652009-02-21 6.4.9-7 Chris Madison <madisonblu@gmail...>
1366 * The identify program reads the image pixels when the -format option is
1367 asking for image statistics.
1368 * Much improved ImageMagick validation suite (exercise with 'make check').
1369
13702009-02-18 6.4.9-5 Jon <jon@brick...>
1371 * Processing the arg list -tile is replaced by -sans0 which is 1 char longer

2253
22542007-11-02 6.3.6-6 Cristy <quetzlzacatenango@image...>
2255 * Upgrade to FPX version libfpx-1.2.0.14 (reference
2256 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=10041).
2257 * Modules are searched first in the directories specified by the environment
2258 variables, and then -- if the desired module is not found -- in the
2259 compiled-in path. (reference
2260 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=10039).
2261
22622007-11-01 6.3.6-5 Cristy <quetzlzacatenango@image...>
2263 * Update FPX regression test reference images.
2264 * Fixed Magick++ compile error for Sun Studio 10 compiler.
2265

2267 * The -equalize option now respects the -channel option.
2268
22692007-10-23 6.3.6-4 Anthony <anthony@griffith...>
2270 * Additional Filters: Welsh, Parzen, Lagrangian

2275 * Further expandsion and handling of filters with expert options.
2276 -filter selects from a table of standard filter settings, while
2277 expert options allow complete selection of filter, windowing, support
2278 and blurring options. Includes automatic switch from Sinc to Bessel
2279 for operators using 2 dimentional cylindrical filter, rather than
2280 two pass 1 dimentional orthogonal filters.
2281
22822007-10-14 6.3.6-3 Cristy <quetzlzacatenango@image...>
2283 * Obsolete -support (set filter blur factor)
2284 * Expandsion to add -set/define filter options
2285
22862007-10-12 6.3.6-2 Anthony <anthony@griffith...>
2287 * Least Squares coordinate handling added for -distort methods Affine,
2288 Perspective, Bilinear. This allows for more than the minimal number of
2289 coordinates to be used to 'fit' a distortion function to an image.
2290 This addition will allow the use of image registration to generate
2291 panarama overviews and better geographical coordinate correction.
2292 * Cosolidated the simular methods FlattenImage() and MosaicImage()
2293 into a new layers function MergeImageLayers() method, adding 'flatten'
2294 and 'mosaic' layer methods.
2295 * Addition of another simular layers method 'merge' which 'unlocks' the
2296 normal flatten/mosaic layer merger from the origin, The resulting image
2297 will have a virtual canvas of minimal size with an offset. Also images
2298 with negative offsets will not be clipped by the 'merge' form of the
2299 command. This was created for better layering of distorted images, such
2300 as panarama overlays.
2301 * Bug fix in handling transparency for EWA resampling.
2302 * Access to Resize Filter Functions from resize.c (for resample.c)
2303 with posible future filter sources... Acquire/Destory/Call ResizeFilter()
2304 * All resize filters added to resampling, but filter handling is incomplete.
2305
23062007-10-05 6.3.6-2 Cristy <quetzlzacatenango@image...>
2307 * The box filter no longer produces a black grid when resizing an image
2308 under Mac OS X.
2309 * Respect cropbox for PDF with a subimage specification (e.g.
2310 image.pdf[1-3]).
2311 * Detect proper PDF bounding box when offsets are negative.
2312
23132007-10-02 6.3.6-1 Cristy <quetzlzacatenango@image...>
2314 * Speed up the Fx interpreter.
2315 * Use ULL not ui64 for MinGW 64-bit constants.
2316 * Call SyncCacheView() instead of SyncImagePixels() in WaveImage().
2317 * Close all references to a pixel cache on disk before removing the temporary
2318 file as required under Windows.
2319
23202007-09-29 6.3.6-0 Anthony <anthony@griffith...>
2321 * Added Scaling 'derivitives' to -distort Arc, so image arcing is now
2322 sharp and clear as you approach the center of the distort.
2323 * Added " -set option:distort:viewport 'geometry' " special option
2324 that can be used to override the output image size and offset.
2325 * Fixed experimental use of -filter and -support in Resampling (more later).
2326 * Changed order for coordinate arguments in -distort (for later leastsq
2327 multiple coordinate distortion function fitting)
2328
23292007-09-22 6.3.6-0 Cristy <quetzlzacatenango@image...>
2330 * Check the API version and quantum depth before loading a coder module or
2331 image filter (reference
2332 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=9780).
2333 * Add exception to the image filter signature.
2334 * Get the execution path under Mac OS X.
2335 * TIFFTAG_STRIPBYTECOUNTS requires a uint32 pointer (magick/compress.c).
2336 * Fixed memory leak in CloneString() (reference
2337 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=9763).
2338 * Set S_IRUSR | S_IWUSR | S_IRGRP mode when writing a file in
2339 CopyDelegateFile().
2340
23412007-09-18 6.3.5-9 Anthony <anthony@griffith...>
2342 * Bug fix for +distort in Perspective, also effected PerspectiveProjection
2343
23442007-09-17 6.3.5-10 Cristy <quetzlzacatenango@image...>
2345 * Replace all InterpolatePixelColor() calls to use the ResamplePixelColor()
2346 method instead.
2347 * Map the display program pan icon window for each oversized image.
2348 * The ufraw delegate does not like quotes around the output filename.
2349 * Adjust the sensitivity of a few PerlMagick tests to pass the validation on
2350 a 64-bit FreeBSD system.
2351 * The -level option now works properly for colormapped images.
2352 * Allow Extrapolated blending of images using -blend
2353 http://netpbm.sourceforge.net/doc/extendedopacity.html
2354
23552007-09-12 6.3.5-9 Anthony <anthony@griffith...>
2356 * Major Addition, Area Resampling Functions, (scaled interpolation)
2357 for pixel lookup in Distortion functions. This improves the look in
2358 areas of minification enormousally, especially in situations of infinite
2359 tiling and horizon views. All virtual pixel methods have been handled
2360 to minimise computation time involved with area resampling. To use the
2361 new function distortions need to be able to determine scaling vectors
2362 (distortion function derivitives) for correct working. All
2363 -distort methods, except Arc, uses scaled area resampling.
2364 * Improvements to perspective distort method, to include the correct
2365 differentation between the 'ground' on which the image lies, and the
2366 'sky', the color of which can be set using the -mattecolor setting
2367 (as the distortion invalid pixel color). Background color is retains
2368 for surrounding ground areas. The horizon is also correct anti-aliased
2369 and transparent colors are also allowed, allowing you to add backdrops
2370 of gradients and patterns.

2593 * Added new Composition method, 'ChangeMask' to return pixels
2594 that have changed or will cause a color change in overlays
2595 * Used 'ChangeMask' to implement the "-layers" method
2596 "OptimizeTransparency" to improve the compressibility of
2597 frame optimized GIF animations. See IM Examples...
