2 * Autodetect file type support in Makefile.PL to prevent test failures
4 2010-10-05 6.6.4-10 Anthony Thyssen <A.Thyssen@griffith...>
5 * Added new filter 'Lanczos2D' a 2-lobe Lanczos as defined by
6 Andreas Gustafsson in his thesis "Interactive Image Warping" (page 24)
7 http://www.gson.org/thesis/warping-thesis.pdf
8 * Added filter "Robidoux" whcih is a 'negativally' blurred version
9 of the "Lanczos2D" filter specifically designed to be less 'blurry'
10 for horizontal and vertical lines in no-op distortions.
11 It is now the default filter (if none specified) for EWA resampling.
13 2010-10-05 6.6.4-10 Cristy <quetzlzacatenango@image...>
14 * Add support for "pattern:vertical2" and "pattern:horizontal2".
15 * Add support for "pattern:vertical3" and "pattern:horizontal3".
16 * Properly handle PSD layers with negative heights.
18 2010-10-03 6.6.4-9 Cristy <quetzlzacatenango@image...>
19 * Fix memory assertion with --enable-embeddable (reference
20 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17201).
21 * Don't permit access to pixels when pinging an image (reference
22 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17194).
24 2010-10-02 6.6.4-9 Anthony Thyssen <A.Thyssen@griffith...>
25 * Added sqrt(2) bluring default for Gaussian Filter if used as
26 a Cylindrical EWA filter. This resulted removing the last aliasing
27 issue that was present in tests for Gaussian EWA resampling. Of course
28 it is still a very blury filter for default use in EWA.
29 * Adjusted Variable Mapping Blur Composition so user arguments actual
30 relate properly to the sigma of the blur for a maximum mapping value.
31 * Fix horizon anti-alising for output-scaled perspective distortions.
32 * 'Bessel' filter is now offically and more accuritally named 'Jinc'
33 however 'Bessel' while not visible as a filter option can still be used
34 as an internal alias for 'Jinc'.
36 2010-09-28 6.6.4-8 Nicolas Robidoux <nicolas.robidoux@gmail...>
37 * Chantal Racette double checked the bounding parallelogram computation
38 in resample.c (and I tightened the comments).
40 2010-09-28 6.6.4-8 Cristy <quetzlzacatenango@image...>
41 * Temporary files not always deleted (reference
42 http://www.imagemagick.org/discourse-server/viewtopic.php?f=2&t=15960).
44 2010-09-28 6.6.4-8 Anthony Thyssen <A.Thyssen@griffith...>
45 * Bug fix for -filter point distorts (occasional generating black pixels)
47 2010-09-27 6.6.4-8 Nicolas Robidoux <nicolas.robidoux@gmail...>
48 * Simplified the ClampUpAxes code, the use of its outputs, its comments,
49 and credited Craig DeForest for the "clamp singular values" idea.
50 * No reason to have "insane" precision Sinc in resize.c: Use
51 the 1.2e-12 max. abs. relative error version for Q64 as well as Q32.
53 2010-09-27 6.6.4-8 Anthony Thyssen <A.Thyssen@griffith...>
54 * Replace the blurry "High Quality EWA" technique with a 'Clamped EWA'
55 for Distort Resampling. This makes -distort a whole lot nicer
56 and allows for the use of better cylindrical filters.
58 2010-09-26 6.6.4-7 Anthony Thyssen <A.Thyssen@griffith...>
59 * Fix Point filter for ResizeImage() caused by support limiting the
60 Box weighting function.
62 2010-09-26 6.6.4-6 Cristy <quetzlzacatenango@image...>
63 * Don't allow resize filter weights to go to zero (reference
64 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17132).
66 2010-09-24 6.6.4-6 Nicolas Robidoux <nicolas.robidoux@gmail...>
67 * Now that MagickPIL is a MagickRealType, some casts are unneeded.
69 2010-09-21 6.6.4-6 Cristy <quetzlzacatenango@image...>
70 * Do not break words if caption size is absolute (reference
71 http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=17123).
72 * Don't define HAVE_THREADS for --without-threads configure script option.
74 2010-09-20 6.6.4-5 Nicolas Robidoux <nicolas.robidoux@gmail...>
75 * Modified "magick/resize.c" so that MagickPIL is a MagickRealType number.
76 Some computations were needlessly done in long double precision because
77 PIL forced an automatic upcast wherever it appeared. Changed its name to
78 MagickREALTYPEPI. <- This was later reverted back to MagickPIL.
79 * Modified "magick/resize.c" so that Bohman uses one trig call + one sqrt
80 call instead of two trig calls.
82 2010-09-20 6.6.4-5 Anthony Thyssen <A.Thyssen@griffith...>
83 * modified "magick/resample.c" to allow use of either EWA or HQEWA (default)
84 * Removed LanczosFast from supported filters (SincFast*SincFast is faster)
86 2010-09-19 6.6.4-5 Cristy <quetzlzacatenango@image...>
87 * If IPTC profile is not embedded in an 8bim resource, declare it IPTC
89 * Support %[version] and %[copyright].
90 * Improve performance of the pixel cache.
92 2010-09-18 6.6.4-4 Cristy <quetzlzacatenango@image...>
93 * Automatically set the quantum depth to 16 for HDRI.
95 2010-09-16 6.6.4-2 Cristy <quetzlzacatenango@image...>
96 * IPTC profile not always wrapped properly inside an 8BIM profile.
97 * TIFF tile geometry must be divisible by 16.
99 2010-09-15 6.6.4-2 Anthony Thyssen <A.Thyssen@griffith...>
100 * Rename of SincPolynomial to SincFast for easier user understanding
101 * Ditto for LanczosChebyshev to LanzcosFast
103 2010-09-14 6.6.4-2 Anthony Thyssen <A.Thyssen@griffith...>
104 * Switch default resize filters to using the faster SincPolynomial
105 filter by default internally. However 'Sinc' will still use the
106 Trigonometric function, and can be used to assign the trig version
107 of Sinc() to filters using the filter expert options.
108 * The default filter for 'distort' was found to be a very blurry inaccurate
109 filter function. It was removed and replaced with a correct Gaussian
110 filter (as used by resize)
111 * Added a switch so that "-interpolate filter" will force the use of
112 a cylindrical filter for ALL pixels in distorted images. That is you can
113 use that switch to use a cylindrical filter even for images that are
114 being enlarged by the distortion. However EWA is still currently using
115 a fixed 2.0 sampling radius. This switch complements the use of "-filter
116 point" which turns off EWA filters in favor of interpolation for all
117 pixels in a distorted image. BOTH switches should not be used together.
118 * A bug in the support radius of the EWA resampling function was found,
119 now that correctly defined resize filters are being used. Suddenly Normal
120 Gaussian distortions are not so blurry, and tests with distortions of
121 the 'Rings' image show extremely good and clear results, with only minimal
122 blurring. The filter 'blur' expert option can be used to adjust this
125 The above represents a major improvement forward in the quality of the
126 image distortion operator. But near-unity distortions (no scaling) are
129 2010-09-13 6.6.4-2 Cristy <quetzlzacatenango@image...>
130 * Don't negate the geometry offset for the -extent option.
132 2010-09-09 6.6.4-1 Cristy <quetzlzacatenango@image...>
133 * The RGBO format is now listed as a supported format.
135 2010-09-07 6.6.4-1 Anthony Thyssen <A.Thyssen@griffith...>
136 * Added the Nicolas Robidoux and Chantal Racette Lanczos resize filter
137 function as "LanczosChebyshev" as faster alternative to Lanczos.
138 * Re-code Nicolas Robidoux and Chantal Racette Polynomial Approximation of
139 the Sinc Trigonometric resize filter, as a proper filter to allow
140 direct comparision and speed testing of the filter.
141 * Expanded the "-set option:filter:verbose 1" output, so as to also include
142 the actual functions and other values that were used to create the filter.
144 2010-09-02 6.6.4-0 el_supremo <digipete@shaw...>
145 * Repair a few incorrect LocaleNCompare() calls (ttf.c, ps.c).
147 2010-08-31 6.6.4-0 Cristy <quetzlzacatenango@image...>
148 * Path no longer closed if join style is round (reference
149 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16943).
150 * Add case for BGRQuantum to GetQuantumExtent().
151 * Support no compression on PCX write.
153 2010-08-23 6.6.3-10 Cristy <quetzlzacatenango@image...>
154 * Fixed bug in the raw BGRA coders (reference
155 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16880).
156 * Fix off-by-one error in the PSD coders.
157 * Nicolas Robidoux with the assistance of Chantal Racette contribute an
158 approximation of the sinc function over the interval [-3,3].
159 * Eliminate a small memory leak in LevelizeImageChannel() (reference

161 * Recognize -fx logtwo (reference
162 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16958).
164 2010-08-15 6.6.3-7 Cristy <quetzlzacatenango@image...>
165 * Throw exception if image size differs for the compare program but the
166 -subimage-search option is not specified.
168 2010-08-13 6.6.3-6 Cristy <quetzlzacatenango@image...>
169 * The AdobeRgb.tif TIFF image no longer faults under Windows (reference
170 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16838).
171 * Add -subimage-search option to the compare utility.
173 2010-08-12 6.6.3-5 Cristy <quetzlzacatenango@image...>

175 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16833).
177 2010-08-10 6.6.3-5 Glenn Randers-Pehrson <glennrp@image...>
178 * Emit a warning if the PNG encoder can't satisfy the color type and
179 bit depth requested with a "-define" directive.
181 2010-08-07 6.6.3-4 Cristy <quetzlzacatenango@image...>
182 * The orient option sometimes improperly set "undefined" (reference
183 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16795).
184 * Only list orientation options for the -list orientation option (reference
185 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16801).
186 * Return proper standard deviation for combined channels (reference
187 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16786).
188 * Handle transparency properly for the PSD image format.
190 2010-08-05 6.6.3-3 Glenn Randers-Pehrson <glennrp@image...>
191 * Properly map PNG intent to image->rendering_intent

195 * Support -set density / units.
197 2010-07-31 6.6.3-2 Cristy <quetzlzacatenango@image...>
198 * Only use the first alpha channel in PSD image.
199 * Only use XPM complying colors for XPM images (e.g. green is rgb(0,255,0)).
201 2010-07-27 6.6.3-2 Glenn Randers-Pehrson <glennrp@image...>
202 * Eliminate useless message about assuming zero delay when writing
203 a single-frame MNG, and changed it from Error to Warning when
204 writing a multiple-frame MNG.
206 2010-07-25 6.6.3-1 Glenn Randers-Pehrson <glennrp@image...>
207 * Don't "ping" a PNG image if it is embedded in a MNG. Otherwise the
208 reader tries to read MNG chunks from the interior of the embedded PNG,
209 resulting in an erroneous "corrupted image" message.
211 2010-07-09 6.6.3-1 Cristy <quetzlzacatenango@image...>
212 * Fix memory leak in for corrupt BMP images (reference
213 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16600).
214 * Repair several issues when writing to stdout (reference
215 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16620).
216 * A GIF image with the .bgr extension is still a GIF (reference
217 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16662).
219 2010-07-07 6.6.3-1 Glenn Randers-Pehrson <glennrp@image...>
220 * The PNG decoder failed to handle the tRNS chunk properly for grayscale
221 images where the png bit_depth was not the same as the quantum depth,
222 and the transparent color was not black.
224 2010-07-01 6.6.3-0 Chris Madison <madisonblu@gmail...>
225 * Pinging the DJVU image format no longer faults.
226 * Check for time-limit-exceeded in only one thread.
227 * Reading filenames from a file (e.g. @filenames) no longer includes the
228 utility name (side effect of StringToArgv() method).
230 2010-06-28 6.6.2-10 Cristy <quetzlzacatenango@image...>
231 * Support the tiff:fill-order define.

242 * Skip byte when DDS bitcount is 32 (reference
243 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16487).
244 * Montage now uses final background setting (e.g. montage -background none ...
245 -background lightblue show:).
246 * Do not annotate directory paths in ListFiles().
247 * Reset the image matte for png:color-type=2.
249 2010-06-17 6.6.2-7 Cristy <quetzlzacatenango@image...>
250 * Support new label:pointsize property.
251 * Miscellany->Slide Show, in the display program, now cycles through the
253 * Recognize certain hex color values (e.g. #b9e1cc00) for the -fx argument.
254 * Reduce memory requirements when dithering on the iPhone.
255 * Command line operators no longer affected by settings that appear after
256 them (e.g. -splice 10x0+0+0 -gravity center).
257 * Compute the proper DPX user data field size.
259 2010-06-15 6.6.2-6 Cristy <quetzlzacatenango@image...>
260 * Fix some nits to keep the clang compiler happy.
262 2010-06-14 6.6.2-5 Anthony Thyssen <A.Thyssen@griffith...>
263 * Fix transprancy handling for Morphology Convolve
264 * Adjustments of Hit And Miss and Edge Detection kernel definitions
265 * Added 'ThinDiagonals' Thinning Kernel + two sub-types
266 * Handling for Convolution of 1-D vertical kernels.
267 However this was removed (using #if-#endif) as I found it slower in tests!
269 2010-06-12 6.6.2-5 Cristy <quetzlzacatenango@image...>
270 * mogrify -format properly handles compressed image filename (e.g.
271 -format jpg logo.png.bz2).
272 * Respect +dither option when saving to the GIF image format.
274 2010-06-08 6.6.2-4 Cristy <quetzlzacatenango@image...>
275 * End of string sentinal is \n not \r.
277 2010-06-06 6.6.2-3 Glenn Randers-Pehrson <glennrp@image...>
278 * Don't decode pixels in coders/png.c when image->ping is set.
280 2010-06-06 6.6.2-3 Cristy <quetzlzacatenango@image...>
281 * Reset image filename when reading inline images.
282 * Don't clamp floating point values for HDRI-enabled ImageMagick.
284 2010-05-25 6.6.2-2 Anthony Thyssen <A.Thyssen@griffith...>

287 * Spelling correction: Manhatten -> Manhattan
289 2010-06-01 6.6.2-2 Glenn Randers-Pehrson <glennrp@image...>
290 * Properly scale color components of the PNG bKGD chunk.
291 * Prevent MNG divide by zero in calculation of frame_timeout. Set
292 both frame_delay and frame_timeout to infinite when ticks_per_second
293 is zero, as required by the MNG spec.
295 2010-05-31 6.6.2-2 Cristy <quetzlzacatenango@image...>

301 * Prevent coders/png.c from attempting to write an empty tRNS chunk.
303 2010-05-25 6.6.2-1 Anthony Thyssen <A.Thyssen@griffith...>
304 * Fix for Square Array Rotates (off center origin rotate)
305 * Added HitAndMiss kernel Ridges2 to find 2 pixel thick ridges
306 * Added FreiChen:0,{angle} FreiChen:{angle} and FreiChen:-1 variations

315 * Use 64-bit types when compiling with the 64-bit Visual C++ compiler under
317 * Prevent MNG divide by zero in calculation of frame_delay (reference
318 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16320).
320 2010-05-23 6.6.2-0 Anthony Thyssen <A.Thyssen@griffith...>
321 * Third Re-write of MorphologyApply() to better handle compound methods.
322 * Implemented -set option:morphology:compose for merging results of
323 multiple kernels. "None" means re-iterate results with next kernel.
324 While "Undefined" means to use the internal default for a method.
325 Thinning, Thickening, HitAndMiss, Convolve, Correlate defaults to "None"
326 while HitAndMiss defaults to "Lighten" (union of all kernel results).
327 Other morphology methods defaults still to be decided.
328 * Added HitAndMiss Kernel: Ridges (find ridges and pixel width lines)
329 * Rotation Expansion of single kernels '^' and '@' flags in arguments
330 EG: -set option:showkernel 1 -morphology Convolve 'Blur:0x2^'
331 * ExpandKernelInfo() (rotation expand) now groks symmetrical kernels.
332 So the above will only produce a list of 2 kernels, not 4 kernels
334 2010-05-18 6.6.2-0 Anthony Thyssen <A.Thyssen@griffith...>
335 * Separation of internal function MorphologyApply() from
336 MorphologyImageChannel() to calls to convolve without user settings.
337 * Rewrite of MorphologyApply() to output better 'verbose' messages
338 * Better handling of Gaussian tyle filters (bug fixes)
339 * Bug fix and optimization of kernel size calculations in "gem.c"
340 * Allow '^' or '@' flags in 'user defined' kernel size arguments to
341 expand kernel into a rotated list.
342 EG: -set option:showkernel 1 -morphology Thinning '3@: 0,1,0 0,1,0 0,0,0'
343 * Allow a scaled unity kernel to be added to kernel (EdgeDet->Sharpen)
344 EG: -set option:convolve:scale [kernel_scale][^!],[unity_scale][%]
345 * Addition of "Laplacian of Gaussian" (LOG), also known as Mexican Hat
346 EG: -morphology convolve LOG:0x1
347 * Added FreiChen, Kirsch Convolution kernels
348 * Added Descrete 'Laplacian of Gaussian' kernels (Laplacian type 15 and 19)
349 * Added Edges HitAndMiss Kernel
351 2010-05-17 6.6.2-0 Cristy <quetzlzacatenango@image...>
352 * PSD images require a proper layer to support an alpha channel.
353 * Enable PFM endian support.
354 * Add context to -border for montage. Inside the parenthesis it adds a border
355 to the image otherwise it sets the border for the layout manager.
356 * 24-bit BMP images are not colormapped even if header colors != 0.
357 * Set DPX user data like this: -set profile dpx:userdata.txt.
358 * Make sure Lab => RGB => Lab survives the round trip.
360 2010-05-15 6.6.1-10 Cristy <quetzlzacatenango@image...>
361 * Use ScaleCharToQuantum() in coders/src.c (reference
362 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16229).
363 * Don't clamp HDRI EXR pixels.
365 2010-05-14 6.6.1-9 Cristy <quetzlzacatenango@image...>
366 * Increase the estimated # points for the path drawing primitive.
367 * Remove any prior resolution block from PSD before writing the new block.
369 2010-05-14 6.6.1-9 Anthony Thyssen <A.Thyssen@griffith...>
370 * Addition of more Morphological/Convolution Kernels.
371 DOG (Difference of Gaussians) and DOB (Difference of Blurs),
372 EG: -morphology convolve DOG:0x1,3
373 -morphology convolve DOB:0x1,3,90
374 * Added Prewitt, Roberts, Compass Convolution Kernels
375 * Ring Symbol Kernel (subtraction of Disk from a Disk)
377 2010-05-13 6.6.1-9 Cristy <quetzlzacatenango@image...>
378 * The pixel buffer was underallocated for some image formats when streaming.
380 2010-05-12 6.6.1-8 Anthony Thyssen <A.Thyssen@griffith...>
381 * Implementation of Pattern Matching Morphology methods
382 HitAndMiss, Thicken, Thinning
383 * Reporting of Kernel Strings that fail to parse (though not why)
384 * Parsing of Multiple Kernel Strings, generating a list of kernels
385 * Union of results from Multiple Kernels for HitAndMiss method
386 * Interated Multiple Kernels for all other morphology methods
387 * Added many new kernels for HitAndMiss and Convolution
388 Sobel, Laplacian, Cross, Peaks, Corners, LineEnds, LineJunctions,
389 ConvexHull (for Thicken), Skeleton (for Thinning)
391 2010-05-08 6.6.1-8 Glenn Randers-Pehrson <glennrp@image...>
392 * Use proper background.index when writing indexed PNG, if the background
393 color is in the palette.
395 2010-05-08 6.6.1-7 Cristy <quetzlzacatenango@image...>
396 * Fix improper 'invalid colormap index' PNG bug.
397 * Fix PerlMagick compile exception.
399 2010-05-07 6.6.1-6 Anthony Thyssen <A.Thyssen@griffith...>
400 * Added % and ! modification flags to morphology distance kernel
401 scaling factor, for easier usage.
402 * Bug fix for compose math channel handling and morphology diff usage
404 2010-05-06 6.6.1-6 Cristy <quetzlzacatenango@image...>
405 * Do not claim gray colorspace if gray image includes a non-gray pixel.
406 * Initialize BMP alpha channel to opaque for RGB images.
407 * Fixed under allocation for round rectangles.
408 * The -list option returns a 0 status as expected.
410 2010-05-06 6.6.1-6 Anthony Thyssen <A.Thyssen@griffith...>
411 * Made use of new no-'sync' channel enabled mathematical compose methods
412 for the difference morphology methods. These should now work correctly
413 for specific channels, and more importantly for alpha shaped morphology.
415 2010-05-05 6.6.1-6 Glenn Randers-Pehrson <glennrp@image...>
416 * Fixed bugs with losing the opacity channel while writing some PNG images.
417 (bug reported by Anthony T.)
419 2010-05-05 6.6.1-6 Glenn Randers-Pehrson <glennrp@image...>
420 * Simplified and corrected rowbytes calculation in coders/png.c and
423 2010-05-05 6.6.1-6 Anthony Thyssen <A.Thyssen@griffith...>
424 * Rename of "Add" and "Subtract" compositions to "ModulusAdd" and
425 "ModulusSubtract" for more clarity of there functions. Old names
426 will continue to work as expected.
427 * Fix "Minus", "ModulusAdd", and "ModulusSubtract" to follow
428 normal SVG 'Over' blending specifications, (see next for override)
429 Note that this does NOT include the "Plus" composition method which has
430 SVG definition for it to use a 'Plus' blending rather than 'Over' blending.
432 * By default mathematical compositions work as per SVG definition. That is
433 the results are synchronized with 'Over' alpha-blending (except "Plus"
434 which uses 'plus' alpha-blending).
436 By removing the default 'sync' flag from the -channel setting however
437 Break this inter-channel synchronization and do the mathematical operations
438 only on the individual channels as specified by the -channel setting.
439 That is do 'channel' math rather than 'SVG' composition.
441 With this change you can then use mathematical composition methods on
442 individual channels or even with the alpha channel of images.

587 * Finalized -set option:convolve:scale kernel normalize/scale option
589 2010-02-16 6.5.9-7 Cristy <quetzlzacatenango@image...>
590 * TransformImage() resets the image blob when called in the PICT decoder;
591 use SetImageExtent() instead.
593 2010-02-14 6.5.9-6 Cristy <quetzlzacatenango@image...>
594 * Support PSD RLE compression.
596 2010-02-13 6.5.9-5 Cristy <quetzlzacatenango@image...>

612 EdgeIn, EdgeOut, Edge, TopHat, BottomHat
613 * Ensuring original kernels passed to morphology are cloned before being
614 modified for use by specific methods (EG: convolve scale/normalize)
616 2010-02-03 6.5.9-2 Cristy <quetzlzacatenango@image...>

623 * added use of -precision in 'showkernel' output of -morphology
624 * correct use of a 'reflected kernel' for 'Convolve' 'Dilate' and
625 'Distance' Morphology primatives. This does not have a performance hit,
626 though is only truely applicable when the kernel is asymmetric. Note that
627 'Erode' does not use a 'reflected' kernel, so that 'Open' and 'Close'
628 operations work properly. This 'reflected usage is defined by online
629 morphology lecture notes (Google for "EECE Binary Morphology")
630 * Added convolve kernel scaling setting "-set option:convolve:scale N"
631 If undefined morphology convolve does not do any scaling or normalization
632 of the convolution kernel. A value of 0.0 causes normalization for both

656 2010-01-04 6.5.9-0 Anthony Thyssen <A.Thyssen@griffith...>
657 * Added Kernel Generator to generate kernels from user strings, which
658 allows the generation in many built in kernels for both Convolution
659 and other Morphological methods. New Kernels currently include..
660 Convolution: Gaussian, Blur, Comet
661 Morphological: Rectangle, Square, Diamond, Disk, Plus
662 Distance: Chebyshev, Manhatten, Knight, Euclidean
663 And both old and new (rectangular) user defined kernel specifications
664 including the use of 'nan' to represent elements which are not part
665 of the kernel definition. List built-in kernel types use "-list kernel"
666 * Added -morphology {method}[:{iteration}] {kernel_string}
667 Initial methods includes no only the basic morphology methods: Dilate,
668 Erode, Open, Close; and a pixel color preserving 'Intensity' version, but
669 also the special methods: Convolve, and Distance. Of course the
670 appropriate kernel should be provided for each specific method.
672 2010-01-01 6.5.9-0 Cristy <quetzlzacatenango@image...>
673 * Add OpenCL-enabled filter (e.g. convert image.png -process
674 "convolve '-1, -1, -1, -1, 9, -1, -1, -1, -1'" image.jpg).
675 * Added StringTo...() processing functions
677 2009-12-27 6.5.8-9 Anthony Thyssen <A.Thyssen@griffith...>

875 enabled by default. This replaces the current 'channels not modified'
876 type handling thought IM.
877 * Modified -channel parsing to continue looking for words, after handling

942 Including non-overlapping regions bugs found in in operators Divide,
943 ColorDodge, VividLight. And the handling of transparency to follow
944 standard 'Over' Blending in Divide. Only math methods not looked at are
945 the addition methods Plus, Add, Minus, and Subtract, which do not follow
946 normal 'Over' alpha blending behaviour, for the purposes of mask handling.
948 2009-07-12 6.5.4-3 Anthony Thyssen <A.Thyssen@griffith...>
949 * Addition of user definable 'Mathematics' compose method
950 -compose Mathematics -set option:compose:args A,B,C,D -composite
951 Will implement the formula f(Sc,Dc) = A*Sc*Dc + B*Sc + C*Dc + D

1017 * Improve FITS keyword parser.
1019 2009-06-14 6.5.3-7 Anthony Thyssen <A.Thyssen@griffith...>
1020 * Cleanup of compose 'displace' of old useless code that is not used.
1021 * Implement a compose 'distort' mapping method,
1022 This is basically exactly like 'displace' but relative to a fixed point
1023 which may be user supplied as +X+Y
1024 * Default scaling to width/2 and height/2 of overlay (100% scale)
1025 with a distortion 'center' to the middle of the overlay image
1026 * If a '%' flag given scale displacement relative to image size
1027 * If a '!' flag given make scale and center relative to 'background' image
1028 instead of the overlay map.
1029 * If no 'height' scale given, use the X scale.
1031 2009-06-13 6.5.3-6 Anthony Thyssen <A.Thyssen@griffith...>
1032 * Fixed bug for compose methods, Hue, Saturate, Luminize

1040 * Fixed "convert" to merge the third 'mask' image into the 'source' image
1041 for correct handling of 2 dimensional -compose "displace".
1042 * Fixed PerlMagick Composite() for the same thing.
1043 * Modified compose "Displace" so displacement image's alpha channel can be
1044 used to mask the transparency of the overlay area.
1046 2009-06-07 6.5.3-4 Cristy <quetzlzacatenango@image...>
1047 * Added the HALD image Color LUT, and a no-op HALD: image generator.
1048 See Introduction at http://www.quelsolaar.com/technology/clut.html
1050 2009-06-07 6.5.3-4 Anthony Thyssen <A.Thyssen@griffith...>
1051 * Changed CompositeImageChannel() so that extra compose arguments are
1052 now passed in the ImageArtifact "compose:args". This can be assigned to
1053 images using -set "option:compose:args" 'args' where args are defined
1054 using 'geometry' style or 'comma separated numbers'.
1055 * Declared the special flag needed for Composite Tiling as the ImageArtifact
1056 "compose:outside-overlay".

1109 2009-05-14 6.5.2-5 Glenn Randers-Pehrson <glennrp@image...>
1110 * Updated help output and command-line options documentation to bring
1111 the -alpha options up to date with what's actually in the code.
1113 2009-05-13 6.5.2-5 Glenn Randers-Pehrson <glennrp@image...>
1114 * Change "depreciated" to "deprecated" in several files.

1123 * Combined layer of transparent PSD image was not being read properly.
1125 2009-05-06 6.5.2-3 Glenn Randers-Pehrson <glennrp@image...>
1126 * Progress on "-define png:bit-depth=value" and "-define png:color-type=value"
1127 It is now able to write an opaque black-and-white image in any of the 15
1128 valid combinations of PNG color-type and bit-depth.
1129 * Fixed a regression with writing sub-8-bit grayscale PNGs.
1131 2009-05-06 6.5.2-2 Chris Madison <madisonblu@gmail...>
1132 * Create 8-bit TIFF images if -depth is set to 8 and HDRI-enable ImageMagick.
1134 2009-05-04 6.5.2-1 Chris Madison <madisonblu@gmail...>
1135 * Accept file lists on the command line (e.g. echo "rose: rose.png" |
1137 * Duplicate line in tiff.c breaking read of zip compressed tif (reference
1138 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=13688).
1139 * Support policies to permit or deny any coder, delegate, filter, or file
1140 path (see policy.xml).
1142 2009-05-02 6.5.2-0 Chris Madison <madisonblu@gmail...>
1143 * The mogrify -crop option returns multiple images if an x/y offset is not
1144 specified (e.g. -crop 100x100).
1145 * Generate a proper file path for -path @filelist.txt (reference
1146 http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=13671).
1148 2009-05-01 6.5.2-0 Glenn Randers-Pehrson <glennrp@image...>
1149 * Accept "-define png:bit-depth=value" and "-define png:color-type=value"
1150 options. This is work-in-progress with the objective of being able to
1151 precisely specify the type of PNG file to be written. The previously-used
1152 internal attribute "png:bit-depth" that was used to communicate between
1153 the PNG writer and the JNG writer is changed to "png:bit-depth-written".
1154 This feature needs testing. It is important to note that this feature
1155 cannot be used to force the PNG to use a bit-depth or color-type that
1156 does not losslessly represent the image. You can, however, cause
1157 the writer to use a larger depth or to use the RGB colorspace when
1158 grayscale or indexed would have been sufficent.
1160 2009-05-01 6.5.1-10 Anthony Thyssen <A.Thyssen@griffith...>
1161 * Fixed the Rmin usage in Depolar and Polar distortions
1162 * The 6th argument (Ato) for Polar/Depolar is now optional and defaults

1165 2009-04-30 6.5.1-10 Cristy <quetzlzacatenango@image...>
1166 * Do not return a black image for -channel RGBA -gaussian (reference
1167 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=13669).
1169 2009-04-28 6.5.1-9 Cristy <quetzlzacatenango@image...>

1179 * Normalize similarity based on reconstruction not the original (reference
1180 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=13626).
1181 * Support multiple JPEG images encapsulated within DICOM.
1183 2009-04-23 6.5.1-6 Cristy <quetzlzacatenango@image...>
1184 * Msys does not understand NAME_MAX.

1189 2009-04-21 6.5.1-4 Glenn Randers-Pehrson <glennrp@image...>
1190 * Check error return from CompressColormapTransFirst() in coders/png.c
1192 2009-04-21 6.5.1-4 Glenn Randers-Pehrson <glennrp@image...>
1193 * Refrain from modifying image struct members (color, depth, matte)
1194 while writing PNG datastreams.
1196 2009-04-21 6.5.1-4 Glenn Randers-Pehrson <glennrp@image...>
1197 * Sometimes the PNG8: format would produce 1-, 2-, or 4-bit PNG datastreams.
1198 Now it always produces 8-bit datastreams as users probably expect.
1200 2009-04-21 6.5.1-4 Glenn Randers-Pehrson <glennrp@image...>
1201 * Suppressed "shadowed declaration" warnings in coders/jpeg.c and
1202 coders/png.c that are triggered by "-Wshadow" gcc compiler flag.

1221 2009-04-11 6.5.1-2 Anthony Thyssen <A.Thyssen@griffith...>
1222 * Rename existing "Bilinear" distortion as "BilinearReverse"
1223 * Added forward mapped bilinear distort as "BilinearForward"
1224 * The "Bilinear" distort is temporarily obsoleted but will eventually
1225 be added as a "BilinearReverse" and "BilinearForward" combination
1226 mapping though a unit square.
1227 * Sparse Gradient internally uses "BilinearReverse" for its "Bilinear"
1228 gradient function as that method is the direct use of such equations.

1874 Function maps black and white values to the given level values.
1875 Rather than mapping the given level values to black and white.
1876 Bacically a 'reverse-level' function, with different input args.
1877 * Set +level or a '!' flag in -level or LevelImage() to call
1878 the new 'reverse-level' function LevelizeImageChannels().
1879 * More work on IsMagickColorSimular() to fix relationship between
1880 transparent-black and opaque-black, which was matched as 'simular'.
1881 Also attempts to fix 'K' channel handling for CMYK colorspace.
1882 More work on this to come.

2000 * Instead of masking the PNG tRNS values when reducing from 16-bit,
2001 set image->matte to MagickFalse and emit a warning. This will produce
2002 behavior similar to that of libpng-1.2.27 (and libpng-1.2.19 and earlier).

2227 2007-11-03 6.3.6-7 Chris Madison <madisonblu@hotma...>
2228 * MAGICK_ERX_SRCS should be MAGICK_EXR_SRCS in coders/Makefile.am.
2230 2007-11-02 6.3.6-6 Cristy <quetzlzacatenango@image...>
2231 * Upgrade to FPX version libfpx-1.2.0.14 (reference
2232 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=10041).
2233 * Modules are searched first in the directories specified by the environment
2234 variables, and then -- if the desired module is not found -- in the
2235 compiled-in path. (reference
2236 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=10039).

2251 * Further expandsion and handling of filters with expert options.
2252 -filter selects from a table of standard filter settings, while
2253 expert options allow complete selection of filter, windowing, support
2254 and blurring options. Includes automatic switch from Sinc to Bessel
2255 for operators using 2 dimentional cylindrical filter, rather than
2256 two pass 1 dimentional orthogonal filters.
2258 2007-10-14 6.3.6-3 Cristy <quetzlzacatenango@image...>
2259 * Obsolete -support (set filter blur factor)
2260 * Expandsion to add -set/define filter options
2262 2007-10-12 6.3.6-2 Anthony <anthony@griffith...>
2263 * Least Squares coordinate handling added for -distort methods Affine,
2264 Perspective, Bilinear. This allows for more than the minimal number of
2265 coordinates to be used to 'fit' a distortion function to an image.
2266 This addition will allow the use of image registration to generate
2267 panarama overviews and better geographical coordinate correction.
2268 * Cosolidated the simular methods FlattenImage() and MosaicImage()
2269 into a new layers function MergeImageLayers() method, adding 'flatten'
2270 and 'mosaic' layer methods.
2271 * Addition of another simular layers method 'merge' which 'unlocks' the
2272 normal flatten/mosaic layer merger from the origin, The resulting image
2273 will have a virtual canvas of minimal size with an offset. Also images
2274 with negative offsets will not be clipped by the 'merge' form of the
2275 command. This was created for better layering of distorted images, such
2276 as panarama overlays.
2277 * Bug fix in handling transparency for EWA resampling.
2278 * Access to Resize Filter Functions from resize.c (for resample.c)
2279 with posible future filter sources... Acquire/Destory/Call ResizeFilter()
2280 * All resize filters added to resampling, but filter handling is incomplete.
2282 2007-10-05 6.3.6-2 Cristy <quetzlzacatenango@image...>
2283 * The box filter no longer produces a black grid when resizing an image
2285 * Respect cropbox for PDF with a subimage specification (e.g.
2287 * Detect proper PDF bounding box when offsets are negative.
2289 2007-10-02 6.3.6-1 Cristy <quetzlzacatenango@image...>
2290 * Speed up the Fx interpreter.
2291 * Use ULL not ui64 for MinGW 64-bit constants.
2292 * Call SyncCacheView() instead of SyncImagePixels() in WaveImage().
2293 * Close all references to a pixel cache on disk before removing the temporary
2294 file as required under Windows.
2296 2007-09-29 6.3.6-0 Anthony <anthony@griffith...>
2297 * Added Scaling 'derivitives' to -distort Arc, so image arcing is now
2298 sharp and clear as you approach the center of the distort.
2299 * Added " -set option:distort:viewport 'geometry' " special option
2300 that can be used to override the output image size and offset.
2301 * Fixed experimental use of -filter and -support in Resampling (more later).
2302 * Changed order for coordinate arguments in -distort (for later leastsq
2303 multiple coordinate distortion function fitting)
2305 2007-09-22 6.3.6-0 Cristy <quetzlzacatenango@image...>
2306 * Check the API version and quantum depth before loading a coder module or
2307 image filter (reference
2308 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=9780).
2309 * Add exception to the image filter signature.
2310 * Get the execution path under Mac OS X.
2311 * TIFFTAG_STRIPBYTECOUNTS requires a uint32 pointer (magick/compress.c).
2312 * Fixed memory leak in CloneString() (reference
2313 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=9763).
2314 * Set S_IRUSR | S_IWUSR | S_IRGRP mode when writing a file in
2317 2007-09-18 6.3.5-9 Anthony <anthony@griffith...>
2318 * Bug fix for +distort in Perspective, also effected PerspectiveProjection
2320 2007-09-17 6.3.5-10 Cristy <quetzlzacatenango@image...>
2321 * Replace all InterpolatePixelColor() calls to use the ResamplePixelColor()
2323 * Map the display program pan icon window for each oversized image.
2324 * The ufraw delegate does not like quotes around the output filename.
2325 * Adjust the sensitivity of a few PerlMagick tests to pass the validation on
2326 a 64-bit FreeBSD system.
2327 * The -level option now works properly for colormapped images.
2328 * Allow Extrapolated blending of images using -blend
2329 http://netpbm.sourceforge.net/doc/extendedopacity.html
2331 2007-09-12 6.3.5-9 Anthony <anthony@griffith...>
2332 * Major Addition, Area Resampling Functions, (scaled interpolation)
2333 for pixel lookup in Distortion functions. This improves the look in
2334 areas of minification enormousally, especially in situations of infinite
2335 tiling and horizon views. All virtual pixel methods have been handled
2336 to minimise computation time involved with area resampling. To use the
2337 new function distortions need to be able to determine scaling vectors
2338 (distortion function derivitives) for correct working. All
2339 -distort methods, except Arc, uses scaled area resampling.
2340 * Improvements to perspective distort method, to include the correct
2341 differentation between the 'ground' on which the image lies, and the
2342 'sky', the color of which can be set using the -mattecolor setting
2343 (as the distortion invalid pixel color). Background color is retains
2344 for surrounding ground areas. The horizon is also correct anti-aliased
2345 and transparent colors are also allowed, allowing you to add backdrops
2346 of gradients and patterns.

2409 2007-07-25 6.3.5-4 Cristy <quetzlzacatenango@image...>
2410 * Remove extranous break statement so -type option properly sets the
2411 image_info->type member (reference
2412 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=9261).
2414 2007-07-21 6.3.5-4 Anthony <anthony@griffith...>
