1 2010-10-03 6.6.4-9 Cristy <quetzlzacatenango@image...>
2 * Fix memory assertion with --enable-embeddable (reference
3 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17201).
4 * Don't permit access to pixels when pinging an image (reference
5 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17194).
6 * Add support for pattern:vertical2 and pattern:horizontal2.
8 2010-10-02 6.6.4-9 Anthony Thyssen <A.Thyssen@griffith...>
9 * Added sqrt(2) bluring default for Gaussian Filter if used as a
10 Cylindrical EWA filter. This resulted in the last aliasing issue
11 that was present in tests for Gaussian EWA resampling.
12 However it is still a very blury filter for default use in EWA.
13 * Adjusted Variable Mapping Blur Composition so user arguments actual
14 relate properly to the sigma of the blur for a maximum mapping value.
15 * Fix horizon anti-alising for output scaled perspective distortions.
16 * 'Bessel' filter is nor offically and more accuritally named 'Jinc'
17 however 'Bessel' while not visible as a filter option can still be used
18 as an internal alias for 'Jinc'.
20 2010-09-28 6.6.4-8 Nicolas Robidoux <nicolas.robidoux@gmail...>
21 * Chantal Racette double checked the bounding parallelogram computation
22 in resample.c (and I tightened the comments).
24 2010-09-28 6.6.4-8 Cristy <quetzlzacatenango@image...>
25 * Temporary files not always deleted (reference
26 http://www.imagemagick.org/discourse-server/viewtopic.php?f=2&t=15960).
28 2010-09-27 6.6.4-8 Nicolas Robidoux <nicolas.robidoux@gmail...>
29 * Simplified the ClampUpAxes code, the use of its outputs, its
30 comments, and credited Craig DeForest for the "clamp singular values"
32 * No reason to have "insane" precision Sinc in resize.c: Use
33 the 1.2e-12 max. abs. relative error version for Q64 as well as Q32.
35 2010-09-27 6.6.4-8 Anthony Thyssen <A.Thyssen@griffith...>
36 * Replace the blurry "High Quality EWA" technique with a 'Clamped EWA'
37 for Distort Resampling. This makes -distort a whole lot nicer
38 and allows for the use of better cylindrical filters.
39 * Bug fix for -filter point distorts (occasional generating black pixels)
41 2010-09-26 6.6.4-7 Anthony Thyssen <A.Thyssen@griffith...>
42 * Fix Point filter for ResizeImage() caused by support limiting the
43 Box weighting function.
45 2010-09-26 6.6.4-6 Cristy <quetzlzacatenango@image...>
46 * Don't allow resize filter weights to go to zero (reference
47 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17132).
49 2010-09-24 6.6.4-6 Nicolas Robidoux <nicolas.robidoux@gmail...>
50 * Now that MagickPIL is a MagickRealType, some casts are unneeded.
52 2010-09-21 6.6.4-6 Cristy <quetzlzacatenango@image...>
53 * Do not break words if caption size is absolute (reference
54 http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=17123).
55 * Don't define HAVE_THREADS for --without-threads configure script option.
57 2010-09-20 6.6.4-5 Nicolas Robidoux <nicolas.robidoux@gmail...>
58 * Modified "magick/resize.c" so that MagickPIL is a MagickRealType number.
59 Some computations were needlessly done in long double precision because
60 PIL forced an automatic upcast wherever it appeared. Changed its name to
61 MagickREALTYPEPI. <- This was later reverted back to MagickPIL.
62 * Modified "magick/resize.c" so that Bohman uses one trig call + one sqrt
63 call instead of two trig calls.
65 2010-09-20 6.6.4-5 Anthony Thyssen <A.Thyssen@griffith...>
66 * modified "magick/resample.c" to allow use of either EWA or HQEWA (default)
67 * Removed LanczosFast from supported filters (SincFast*SincFast is faster)
69 2010-09-19 6.6.4-5 Cristy <quetzlzacatenango@image...>
70 * If IPTC profile is not embedded in an 8bim resource, declare it IPTC
72 * Support %[version] and %[copyright].
73 * Improve performance of the pixel cache.
75 2010-09-18 6.6.4-4 Cristy <quetzlzacatenango@image...>
76 * Automatically set the quantum depth to 16 for HDRI.
78 2010-09-16 6.6.4-2 Cristy <quetzlzacatenango@image...>
79 * IPTC profile not always wrapped properly inside an 8BIM profile.
80 * TIFF tile geometry must be divisible by 16.
82 2010-09-15 6.6.4-2 Anthony Thyssen <A.Thyssen@griffith...>
83 * Rename of SincPolynomial to SincFast for easier user understanding
84 * Ditto for LanczosChebyshev to LanzcosFast
86 2010-09-14 6.6.4-2 Anthony Thyssen <A.Thyssen@griffith...>
87 * Switch default resize filters to using the faster SincPolynomial
88 filter by default internally. However 'Sinc' will still use the
89 Trigonometric function, and can be used to assign the trig version
90 of Sinc() to filters using the filter expert options.
91 * The default filter for 'distort' was found to be a very blurry inaccurate
92 filter function. It was removed and replaced with a correct Gaussian
93 filter (as used by resize)
94 * Added a switch so that "-interpolate filter" will force the use of
95 a cylindrical filter for ALL pixels in distorted images. That is you can
96 use that switch to use a cylindrical filter even for images that are
97 being enlarged by the distortion. However EWA is still currently using
98 a fixed 2.0 sampling radius. This switch complements the use of "-filter
99 point" which turns off EWA filters in favor of interpolation for all
100 pixels in a distorted image. BOTH switches should not be used together.
101 * A bug in the support radius of the EWA resampling function was found,
102 now that correctly defined resize filters are being used. Suddenly Normal
103 Gaussian distortions are not so blurry, and tests with distortions of
104 the 'Rings' image show extremely good and clear results, with only minimal
105 blurring. The filter 'blur' expert option can be used to adjust this
108 The above represents a major improvement forward in the quality of the
109 image distortion operator. But near-unity distortions (no scaling) are
112 2010-09-13 6.6.4-2 Cristy <quetzlzacatenango@image...>
113 * Don't negate the geometry offset for the -extent option.
115 2010-09-09 6.6.4-1 Cristy <quetzlzacatenango@image...>
116 * The RGBO format is now listed as a supported format.
118 2010-09-07 6.6.4-1 Anthony Thyssen <A.Thyssen@griffith...>
119 * Added the Nicolas Robidoux and Chantal Racette Lanczos resize filter
120 function as "LanczosChebyshev" as faster alternative to Lanczos.
121 * Re-code Nicolas Robidoux and Chantal Racette Polynomial Approximation of
122 the Sinc Trigonometric resize filter, as a proper filter to allow
123 direct comparision and speed testing of the filter.
124 * Expanded the "-set option:filter:verbose 1" output, so as to also include
125 the actual functions and other values that were used to create the filter.
127 2010-09-02 6.6.4-0 el_supremo <digipete@shaw...>
128 * Repair a few incorrect LocaleNCompare() calls (ttf.c, ps.c).
130 2010-08-31 6.6.4-0 Cristy <quetzlzacatenango@image...>
131 * Path no longer closed if join style is round (reference
132 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16943).

134 * Support no compression on PCX write.
136 2010-08-23 6.6.3-10 Cristy <quetzlzacatenango@image...>
137 * Fixed bug in the raw BGRA coders (reference
138 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16880).
139 * Fix off-by-one error in the PSD coders.
140 * Nicolas Robidoux with the assistance of Chantal Racette contribute an
141 approximation of the sinc function over the interval [-3,3].
142 * Eliminate a small memory leak in LevelizeImageChannel() (reference
143 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16951).
144 * Recognize -fx logtwo (reference
145 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16958).
147 2010-08-15 6.6.3-7 Cristy <quetzlzacatenango@image...>
148 * Throw exception if image size differs for the compare program but the
149 -subimage-search option is not specified.
151 2010-08-13 6.6.3-6 Cristy <quetzlzacatenango@image...>
152 * The AdobeRgb.tif TIFF image no longer faults under Windows (reference
153 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16838).
154 * Add -subimage-search option to the compare utility.
156 2010-08-12 6.6.3-5 Cristy <quetzlzacatenango@image...>
157 * The -fx 2e+6/1e+5 argument no longer returns the wrong results (reference
158 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16833).
160 2010-08-10 6.6.3-5 Glenn Randers-Pehrson <glennrp@image...>
161 * Emit a warning if the PNG encoder can't satisfy the color type and
162 bit depth requested with a "-define" directive.
164 2010-08-07 6.6.3-4 Cristy <quetzlzacatenango@image...>
165 * The orient option sometimes improperly set "undefined" (reference
166 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16795).
167 * Only list orientation options for the -list orientation option (reference
168 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16801).
169 * Return proper standard deviation for combined channels (reference
170 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16786).
171 * Handle transparency properly for the PSD image format.
173 2010-08-05 6.6.3-3 Glenn Randers-Pehrson <glennrp@image...>
174 * Properly map PNG intent to image->rendering_intent

177 * Eliminate bogus "invalid colormap index" when pinging ICO images.
178 * Support -set density / units.
180 2010-07-31 6.6.3-2 Cristy <quetzlzacatenango@image...>
181 * Only use the first alpha channel in PSD image.
182 * Only use XPM complying colors for XPM images (e.g. green is rgb(0,255,0)).
184 2010-07-27 6.6.3-2 Glenn Randers-Pehrson <glennrp@image...>
185 * Eliminate useless message about assuming zero delay when writing
186 a single-frame MNG, and changed it from Error to Warning when
187 writing a multiple-frame MNG.
189 2010-07-25 6.6.3-1 Glenn Randers-Pehrson <glennrp@image...>
190 * Don't "ping" a PNG image if it is embedded in a MNG. Otherwise the
191 reader tries to read MNG chunks from the interior of the embedded PNG,
192 resulting in an erroneous "corrupted image" message.
194 2010-07-09 6.6.3-1 Cristy <quetzlzacatenango@image...>
195 * Fix memory leak in for corrupt BMP images (reference
196 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16600).
197 * Repair several issues when writing to stdout (reference
198 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16620).
199 * A GIF image with the .bgr extension is still a GIF (reference
200 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16662).
202 2010-07-07 6.6.3-1 Glenn Randers-Pehrson <glennrp@image...>
203 * The PNG decoder failed to handle the tRNS chunk properly for grayscale
204 images where the png bit_depth was not the same as the quantum depth,
205 and the transparent color was not black.
207 2010-07-01 6.6.3-0 Chris Madison <madisonblu@gmail...>
208 * Pinging the DJVU image format no longer faults.
209 * Check for time-limit-exceeded in only one thread.
210 * Reading filenames from a file (e.g. @filenames) no longer includes the
211 utility name (side effect of StringToArgv() method).
213 2010-06-28 6.6.2-10 Cristy <quetzlzacatenango@image...>
214 * Support the tiff:fill-order define.

224 2010-06-22 6.6.2-8 Cristy <quetzlzacatenango@image...>
225 * Skip byte when DDS bitcount is 32 (reference
226 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16487).
227 * Montage now uses final background setting (e.g. montage -background none ...
228 -background lightblue show:).
229 * Do not annotate directory paths in ListFiles().
230 * Reset the image matte for png:color-type=2.
232 2010-06-17 6.6.2-7 Cristy <quetzlzacatenango@image...>
233 * Support new label:pointsize property.
234 * Miscellany->Slide Show, in the display program, now cycles through the
236 * Recognize certain hex color values (e.g. #b9e1cc00) for the -fx argument.
237 * Reduce memory requirements when dithering on the iPhone.
238 * Command line operators no longer affected by settings that appear after
239 them (e.g. -splice 10x0+0+0 -gravity center).
240 * Compute the proper DPX user data field size.
242 2010-06-15 6.6.2-6 Cristy <quetzlzacatenango@image...>
243 * Fix some nits to keep the clang compiler happy.
245 2010-06-14 6.6.2-5 Anthony Thyssen <A.Thyssen@griffith...>
246 * Fix transprancy handling for Morphology Convolve
247 * Adjustments of Hit And Miss and Edge Detection kernel definitions
248 * Added 'ThinDiagonals' Thinning Kernel + two sub-types
249 * Handling for Convolution of 1-D vertical kernels.
250 However this was removed (using #if-#endif) as I found it slower in tests!
252 2010-06-12 6.6.2-5 Cristy <quetzlzacatenango@image...>
253 * mogrify -format properly handles compressed image filename (e.g.
254 -format jpg logo.png.bz2).
255 * Respect +dither option when saving to the GIF image format.
257 2010-06-08 6.6.2-4 Cristy <quetzlzacatenango@image...>
258 * End of string sentinal is \n not \r.
260 2010-06-06 6.6.2-3 Glenn Randers-Pehrson <glennrp@image...>
261 * Don't decode pixels in coders/png.c when image->ping is set.
263 2010-06-06 6.6.2-3 Cristy <quetzlzacatenango@image...>
264 * Reset image filename when reading inline images.
265 * Don't clamp floating point values for HDRI-enabled ImageMagick.
267 2010-05-25 6.6.2-2 Anthony Thyssen <A.Thyssen@griffith...>
268 * Replaced '^' morphology kernel rotation with two variants '>' and '<'
269 * 'Skeleton' variant to thin down images as symmetrically as possible.
270 * Spelling correction: Manhatten -> Manhattan
272 2010-06-01 6.6.2-2 Glenn Randers-Pehrson <glennrp@image...>
273 * Properly scale color components of the PNG bKGD chunk.
274 * Prevent MNG divide by zero in calculation of frame_timeout. Set
275 both frame_delay and frame_timeout to infinite when ticks_per_second
276 is zero, as required by the MNG spec.
278 2010-05-31 6.6.2-2 Cristy <quetzlzacatenango@image...>
279 * Add x:silent option to prevent beeps when reading the X image format.
280 * Recognize TTF for GetMagicInfo().
281 * Ensure the +set option deletes the image artifact.
283 2010-05-28 6.6.2-1 Glenn Randers-Pehrson <glennrp@image...>
284 * Prevent coders/png.c from attempting to write an empty tRNS chunk.
286 2010-05-25 6.6.2-1 Anthony Thyssen <A.Thyssen@griffith...>
287 * Fix for Square Array Rotates (off center origin rotate)
288 * Added HitAndMiss kernel Ridges2 to find 2 pixel thick ridges
289 * Added FreiChen:0,{angle} FreiChen:{angle} and FreiChen:-1 variations
290 to complete this kernels definition
292 2010-05-24 6.6.2-1 Cristy <quetzlzacatenango@image...>
293 * Respect density when rendering SVG images.
294 * Set AVI handler to the MPEG coder.
295 * Compute the proper DPX user data field size.
296 * Do not interpret a format specifier when enclosed in brackets (e.g.

298 * Use 64-bit types when compiling with the 64-bit Visual C++ compiler under
300 * Prevent MNG divide by zero in calculation of frame_delay (reference
301 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16320).
303 2010-05-23 6.6.2-0 Anthony Thyssen <A.Thyssen@griffith...>
304 * Third Re-write of MorphologyApply() to better handle compound methods.
305 * Implemented -set option:morphology:compose for merging results of
306 multiple kernels. "None" means re-iterate results with next kernel.
307 While "Undefined" means to use the internal default for a method.
308 Thinning, Thickening, HitAndMiss, Convolve, Correlate defaults to "None"
309 while HitAndMiss defaults to "Lighten" (union of all kernel results).
310 Other morphology methods defaults still to be decided.
311 * Added HitAndMiss Kernel: Ridges (find ridges and pixel width lines)
312 * Rotation Expansion of single kernels '^' and '@' flags in arguments
313 EG: -set option:showkernel 1 -morphology Convolve 'Blur:0x2^'
314 * ExpandKernelInfo() (rotation expand) now groks symmetrical kernels.
315 So the above will only produce a list of 2 kernels, not 4 kernels
317 2010-05-18 6.6.2-0 Anthony Thyssen <A.Thyssen@griffith...>
318 * Separation of internal function MorphologyApply() from
319 MorphologyImageChannel() to calls to convolve without user settings.
320 * Rewrite of MorphologyApply() to output better 'verbose' messages
321 * Better handling of Gaussian tyle filters (bug fixes)
322 * Bug fix and optimization of kernel size calculations in "gem.c"
323 * Allow '^' or '@' flags in 'user defined' kernel size arguments to
324 expand kernel into a rotated list.
325 EG: -set option:showkernel 1 -morphology Thinning '3@: 0,1,0 0,1,0 0,0,0'
326 * Allow a scaled unity kernel to be added to kernel (EdgeDet->Sharpen)
327 EG: -set option:convolve:scale [kernel_scale][^!],[unity_scale][%]
328 * Addition of "Laplacian of Gaussian" (LOG), also known as Mexican Hat
329 EG: -morphology convolve LOG:0x1
330 * Added FreiChen, Kirsch Convolution kernels
331 * Added Descrete 'Laplacian of Gaussian' kernels (Laplacian type 15 and 19)
332 * Added Edges HitAndMiss Kernel
334 2010-05-17 6.6.2-0 Cristy <quetzlzacatenango@image...>
335 * PSD images require a proper layer to support an alpha channel.
336 * Enable PFM endian support.
337 * Add context to -border for montage. Inside the parenthesis it adds a border
338 to the image otherwise it sets the border for the layout manager.
339 * 24-bit BMP images are not colormapped even if header colors != 0.
340 * Set DPX user data like this: -set profile dpx:userdata.txt.
341 * Make sure Lab => RGB => Lab survives the round trip.
343 2010-05-15 6.6.1-10 Cristy <quetzlzacatenango@image...>
344 * Use ScaleCharToQuantum() in coders/src.c (reference
345 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=16229).
346 * Don't clamp HDRI EXR pixels.
348 2010-05-14 6.6.1-9 Cristy <quetzlzacatenango@image...>
349 * Increase the estimated # points for the path drawing primitive.
350 * Remove any prior resolution block from PSD before writing the new block.
352 2010-05-14 6.6.1-9 Anthony Thyssen <A.Thyssen@griffith...>
353 * Addition of more Morphological/Convolution Kernels.
354 DOG (Difference of Gaussians) and DOB (Difference of Blurs),
355 EG: -morphology convolve DOG:0x1,3
356 -morphology convolve DOB:0x1,3,90
357 * Added Prewitt, Roberts, Compass Convolution Kernels
358 * Ring Symbol Kernel (subtraction of Disk from a Disk)
360 2010-05-13 6.6.1-9 Cristy <quetzlzacatenango@image...>
361 * The pixel buffer was underallocated for some image formats when streaming.
363 2010-05-12 6.6.1-8 Anthony Thyssen <A.Thyssen@griffith...>
364 * Implementation of Pattern Matching Morphology methods
365 HitAndMiss, Thicken, Thinning
366 * Reporting of Kernel Strings that fail to parse (though not why)
367 * Parsing of Multiple Kernel Strings, generating a list of kernels
368 * Union of results from Multiple Kernels for HitAndMiss method
369 * Interated Multiple Kernels for all other morphology methods
370 * Added many new kernels for HitAndMiss and Convolution
371 Sobel, Laplacian, Cross, Peaks, Corners, LineEnds, LineJunctions,
372 ConvexHull (for Thicken), Skeleton (for Thinning)
374 2010-05-08 6.6.1-8 Glenn Randers-Pehrson <glennrp@image...>
375 * Use proper background.index when writing indexed PNG, if the background
376 color is in the palette.
378 2010-05-08 6.6.1-7 Cristy <quetzlzacatenango@image...>
379 * Fix improper 'invalid colormap index' PNG bug.
380 * Fix PerlMagick compile exception.
382 2010-05-07 6.6.1-6 Anthony Thyssen <A.Thyssen@griffith...>
383 * Added % and ! modification flags to morphology distance kernel
384 scaling factor, for easier usage.
385 * Bug fix for compose math channel handling and morphology diff usage
387 2010-05-06 6.6.1-6 Cristy <quetzlzacatenango@image...>
388 * Do not claim gray colorspace if gray image includes a non-gray pixel.
389 * Initialize BMP alpha channel to opaque for RGB images.
390 * Fixed under allocation for round rectangles.
391 * The -list option returns a 0 status as expected.
393 2010-05-06 6.6.1-6 Anthony Thyssen <A.Thyssen@griffith...>
394 * Made use of new no-'sync' channel enabled mathematical compose methods
395 for the difference morphology methods. These should now work correctly
396 for specific channels, and more importantly for alpha shaped morphology.
398 2010-05-05 6.6.1-6 Glenn Randers-Pehrson <glennrp@image...>
399 * Fixed bugs with losing the opacity channel while writing some PNG images.
400 (bug reported by Anthony T.)
402 2010-05-05 6.6.1-6 Glenn Randers-Pehrson <glennrp@image...>
403 * Simplified and corrected rowbytes calculation in coders/png.c and
406 2010-05-05 6.6.1-6 Anthony Thyssen <A.Thyssen@griffith...>
407 * Rename of "Add" and "Subtract" compositions to "ModulusAdd" and
408 "ModulusSubtract" for more clarity of there functions. Old names
409 will continue to work as expected.
410 * Fix "Minus", "ModulusAdd", and "ModulusSubtract" to follow
411 normal SVG 'Over' blending specifications, (see next for override)
412 Note that this does NOT include the "Plus" composition method which has
413 SVG definition for it to use a 'Plus' blending rather than 'Over' blending.
415 * By default mathematical compositions work as per SVG definition. That is
416 the results are synchronized with 'Over' alpha-blending (except "Plus"
417 which uses 'plus' alpha-blending).
419 By removing the default 'sync' flag from the -channel setting however
420 Break this inter-channel synchronization and do the mathematical operations
421 only on the individual channels as specified by the -channel setting.
422 That is do 'channel' math rather than 'SVG' composition.
424 With this change you can then use mathematical composition methods on
425 individual channels or even with the alpha channel of images.

572 2010-02-16 6.5.9-7 Cristy <quetzlzacatenango@image...>
573 * TransformImage() resets the image blob when called in the PICT decoder;
574 use SetImageExtent() instead.
576 2010-02-14 6.5.9-6 Cristy <quetzlzacatenango@image...>
577 * Support PSD RLE compression.
579 2010-02-13 6.5.9-5 Cristy <quetzlzacatenango@image...>

607 * correct use of a 'reflected kernel' for 'Convolve' 'Dilate' and
608 'Distance' Morphology primatives. This does not have a performance hit,
609 though is only truely applicable when the kernel is asymmetric. Note that
610 'Erode' does not use a 'reflected' kernel, so that 'Open' and 'Close'
611 operations work properly. This 'reflected usage is defined by online
612 morphology lecture notes (Google for "EECE Binary Morphology")
613 * Added convolve kernel scaling setting "-set option:convolve:scale N"
614 If undefined morphology convolve does not do any scaling or normalization
615 of the convolution kernel. A value of 0.0 causes normalization for both

639 2010-01-04 6.5.9-0 Anthony Thyssen <A.Thyssen@griffith...>
640 * Added Kernel Generator to generate kernels from user strings, which
641 allows the generation in many built in kernels for both Convolution
642 and other Morphological methods. New Kernels currently include..
643 Convolution: Gaussian, Blur, Comet
644 Morphological: Rectangle, Square, Diamond, Disk, Plus
645 Distance: Chebyshev, Manhatten, Knight, Euclidean
646 And both old and new (rectangular) user defined kernel specifications
647 including the use of 'nan' to represent elements which are not part
648 of the kernel definition. List built-in kernel types use "-list kernel"
649 * Added -morphology {method}[:{iteration}] {kernel_string}
650 Initial methods includes no only the basic morphology methods: Dilate,
651 Erode, Open, Close; and a pixel color preserving 'Intensity' version, but
652 also the special methods: Convolve, and Distance. Of course the
653 appropriate kernel should be provided for each specific method.
655 2010-01-01 6.5.9-0 Cristy <quetzlzacatenango@image...>
656 * Add OpenCL-enabled filter (e.g. convert image.png -process
657 "convolve '-1, -1, -1, -1, 9, -1, -1, -1, -1'" image.jpg).
658 * Added StringTo...() processing functions
660 2009-12-27 6.5.8-9 Anthony Thyssen <A.Thyssen@griffith...>

854 * Addition of -auto-level and -auto-gamma image enhancements
855 (under trial not yet final)
856 * Addition of a special -channel flag 'sync' which means that the specified
857 channels are to be modified together by the same amount. The flag is
858 enabled by default. This replaces the current 'channels not modified'
859 type handling thought IM.
860 * Modified -channel parsing to continue looking for words, after handling
861 any shorthand channel options. For example: -channel RGB,sync

925 Including non-overlapping regions bugs found in in operators Divide,
926 ColorDodge, VividLight. And the handling of transparency to follow
927 standard 'Over' Blending in Divide. Only math methods not looked at are
928 the addition methods Plus, Add, Minus, and Subtract, which do not follow
929 normal 'Over' alpha blending behaviour, for the purposes of mask handling.
931 2009-07-12 6.5.4-3 Anthony Thyssen <A.Thyssen@griffith...>
932 * Addition of user definable 'Mathematics' compose method
933 -compose Mathematics -set option:compose:args A,B,C,D -composite

1000 * Improve FITS keyword parser.
1002 2009-06-14 6.5.3-7 Anthony Thyssen <A.Thyssen@griffith...>
1003 * Cleanup of compose 'displace' of old useless code that is not used.
1004 * Implement a compose 'distort' mapping method,
1005 This is basically exactly like 'displace' but relative to a fixed point
1006 which may be user supplied as +X+Y
1007 * Default scaling to width/2 and height/2 of overlay (100% scale)
1008 with a distortion 'center' to the middle of the overlay image
1009 * If a '%' flag given scale displacement relative to image size
1010 * If a '!' flag given make scale and center relative to 'background' image
1011 instead of the overlay map.
1012 * If no 'height' scale given, use the X scale.
1014 2009-06-13 6.5.3-6 Anthony Thyssen <A.Thyssen@griffith...>
1015 * Fixed bug for compose methods, Hue, Saturate, Luminize

1024 for correct handling of 2 dimensional -compose "displace".
1025 * Fixed PerlMagick Composite() for the same thing.
1026 * Modified compose "Displace" so displacement image's alpha channel can be
1027 used to mask the transparency of the overlay area.
1029 2009-06-07 6.5.3-4 Cristy <quetzlzacatenango@image...>
1030 * Added the HALD image Color LUT, and a no-op HALD: image generator.
1031 See Introduction at http://www.quelsolaar.com/technology/clut.html
1033 2009-06-07 6.5.3-4 Anthony Thyssen <A.Thyssen@griffith...>
1034 * Changed CompositeImageChannel() so that extra compose arguments are
1035 now passed in the ImageArtifact "compose:args". This can be assigned to
1036 images using -set "option:compose:args" 'args' where args are defined
1037 using 'geometry' style or 'comma separated numbers'.
1038 * Declared the special flag needed for Composite Tiling as the ImageArtifact
1039 "compose:outside-overlay".

1092 2009-05-14 6.5.2-5 Glenn Randers-Pehrson <glennrp@image...>
1093 * Updated help output and command-line options documentation to bring
1094 the -alpha options up to date with what's actually in the code.
1096 2009-05-13 6.5.2-5 Glenn Randers-Pehrson <glennrp@image...>
1097 * Change "depreciated" to "deprecated" in several files.

1108 2009-05-06 6.5.2-3 Glenn Randers-Pehrson <glennrp@image...>
1109 * Progress on "-define png:bit-depth=value" and "-define png:color-type=value"
1110 It is now able to write an opaque black-and-white image in any of the 15
1111 valid combinations of PNG color-type and bit-depth.
1112 * Fixed a regression with writing sub-8-bit grayscale PNGs.
1114 2009-05-06 6.5.2-2 Chris Madison <madisonblu@gmail...>
1115 * Create 8-bit TIFF images if -depth is set to 8 and HDRI-enable ImageMagick.
1117 2009-05-04 6.5.2-1 Chris Madison <madisonblu@gmail...>
1118 * Accept file lists on the command line (e.g. echo "rose: rose.png" |
1120 * Duplicate line in tiff.c breaking read of zip compressed tif (reference
1121 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=13688).
1122 * Support policies to permit or deny any coder, delegate, filter, or file
1123 path (see policy.xml).
1125 2009-05-02 6.5.2-0 Chris Madison <madisonblu@gmail...>
1126 * The mogrify -crop option returns multiple images if an x/y offset is not
1127 specified (e.g. -crop 100x100).
1128 * Generate a proper file path for -path @filelist.txt (reference
1129 http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=13671).
1131 2009-05-01 6.5.2-0 Glenn Randers-Pehrson <glennrp@image...>
1132 * Accept "-define png:bit-depth=value" and "-define png:color-type=value"
1133 options. This is work-in-progress with the objective of being able to
1134 precisely specify the type of PNG file to be written. The previously-used
1135 internal attribute "png:bit-depth" that was used to communicate between
1136 the PNG writer and the JNG writer is changed to "png:bit-depth-written".
1137 This feature needs testing. It is important to note that this feature
1138 cannot be used to force the PNG to use a bit-depth or color-type that
1139 does not losslessly represent the image. You can, however, cause
1140 the writer to use a larger depth or to use the RGB colorspace when
1141 grayscale or indexed would have been sufficent.
1143 2009-05-01 6.5.1-10 Anthony Thyssen <A.Thyssen@griffith...>
1144 * Fixed the Rmin usage in Depolar and Polar distortions
1145 * The 6th argument (Ato) for Polar/Depolar is now optional and defaults

1173 * Check error return from CompressColormapTransFirst() in coders/png.c
1175 2009-04-21 6.5.1-4 Glenn Randers-Pehrson <glennrp@image...>
1176 * Refrain from modifying image struct members (color, depth, matte)
1177 while writing PNG datastreams.
1179 2009-04-21 6.5.1-4 Glenn Randers-Pehrson <glennrp@image...>
1180 * Sometimes the PNG8: format would produce 1-, 2-, or 4-bit PNG datastreams.
1181 Now it always produces 8-bit datastreams as users probably expect.
1183 2009-04-21 6.5.1-4 Glenn Randers-Pehrson <glennrp@image...>
1184 * Suppressed "shadowed declaration" warnings in coders/jpeg.c and

1204 2009-04-11 6.5.1-2 Anthony Thyssen <A.Thyssen@griffith...>
1205 * Rename existing "Bilinear" distortion as "BilinearReverse"
1206 * Added forward mapped bilinear distort as "BilinearForward"
1207 * The "Bilinear" distort is temporarily obsoleted but will eventually
1208 be added as a "BilinearReverse" and "BilinearForward" combination
1209 mapping though a unit square.
1210 * Sparse Gradient internally uses "BilinearReverse" for its "Bilinear"
1211 gradient function as that method is the direct use of such equations.

1857 Function maps black and white values to the given level values.
1858 Rather than mapping the given level values to black and white.
1859 Bacically a 'reverse-level' function, with different input args.
1860 * Set +level or a '!' flag in -level or LevelImage() to call
1861 the new 'reverse-level' function LevelizeImageChannels().
1862 * More work on IsMagickColorSimular() to fix relationship between
1863 transparent-black and opaque-black, which was matched as 'simular'.
1864 Also attempts to fix 'K' channel handling for CMYK colorspace.
1865 More work on this to come.
1867 2008-06-25 6.4.1-9 Cristy <quetzlzacatenango@image...>

1983 * Instead of masking the PNG tRNS values when reducing from 16-bit,
1984 set image->matte to MagickFalse and emit a warning. This will produce
1985 behavior similar to that of libpng-1.2.27 (and libpng-1.2.19 and earlier).

2213 2007-11-02 6.3.6-6 Cristy <quetzlzacatenango@image...>
2214 * Upgrade to FPX version libfpx-1.2.0.14 (reference
2215 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=10041).
2216 * Modules are searched first in the directories specified by the environment
2217 variables, and then -- if the desired module is not found -- in the
2218 compiled-in path. (reference
2219 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=10039).

2234 * Further expandsion and handling of filters with expert options.
2235 -filter selects from a table of standard filter settings, while
2236 expert options allow complete selection of filter, windowing, support
2237 and blurring options. Includes automatic switch from Sinc to Bessel
2238 for operators using 2 dimentional cylindrical filter, rather than
2239 two pass 1 dimentional orthogonal filters.
2241 2007-10-14 6.3.6-3 Cristy <quetzlzacatenango@image...>
2242 * Obsolete -support (set filter blur factor)
2243 * Expandsion to add -set/define filter options
2245 2007-10-12 6.3.6-2 Anthony <anthony@griffith...>
2246 * Least Squares coordinate handling added for -distort methods Affine,
2247 Perspective, Bilinear. This allows for more than the minimal number of
2248 coordinates to be used to 'fit' a distortion function to an image.
2249 This addition will allow the use of image registration to generate
2250 panarama overviews and better geographical coordinate correction.
2251 * Cosolidated the simular methods FlattenImage() and MosaicImage()
2252 into a new layers function MergeImageLayers() method, adding 'flatten'
2253 and 'mosaic' layer methods.
2254 * Addition of another simular layers method 'merge' which 'unlocks' the
2255 normal flatten/mosaic layer merger from the origin, The resulting image
2256 will have a virtual canvas of minimal size with an offset. Also images
2257 with negative offsets will not be clipped by the 'merge' form of the
2258 command. This was created for better layering of distorted images, such
2259 as panarama overlays.
2260 * Bug fix in handling transparency for EWA resampling.
2261 * Access to Resize Filter Functions from resize.c (for resample.c)
2262 with posible future filter sources... Acquire/Destory/Call ResizeFilter()
2263 * All resize filters added to resampling, but filter handling is incomplete.
2265 2007-10-05 6.3.6-2 Cristy <quetzlzacatenango@image...>
2266 * The box filter no longer produces a black grid when resizing an image
2268 * Respect cropbox for PDF with a subimage specification (e.g.
2270 * Detect proper PDF bounding box when offsets are negative.
2272 2007-10-02 6.3.6-1 Cristy <quetzlzacatenango@image...>
2273 * Speed up the Fx interpreter.
2274 * Use ULL not ui64 for MinGW 64-bit constants.
2275 * Call SyncCacheView() instead of SyncImagePixels() in WaveImage().
2276 * Close all references to a pixel cache on disk before removing the temporary
2277 file as required under Windows.
2279 2007-09-29 6.3.6-0 Anthony <anthony@griffith...>
2280 * Added Scaling 'derivitives' to -distort Arc, so image arcing is now
2281 sharp and clear as you approach the center of the distort.
2282 * Added " -set option:distort:viewport 'geometry' " special option
2283 that can be used to override the output image size and offset.
2284 * Fixed experimental use of -filter and -support in Resampling (more later).
2285 * Changed order for coordinate arguments in -distort (for later leastsq
2286 multiple coordinate distortion function fitting)
2288 2007-09-22 6.3.6-0 Cristy <quetzlzacatenango@image...>
2289 * Check the API version and quantum depth before loading a coder module or
2290 image filter (reference
2291 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=9780).
2292 * Add exception to the image filter signature.
2293 * Get the execution path under Mac OS X.
2294 * TIFFTAG_STRIPBYTECOUNTS requires a uint32 pointer (magick/compress.c).
2295 * Fixed memory leak in CloneString() (reference
2296 http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=9763).
2297 * Set S_IRUSR | S_IWUSR | S_IRGRP mode when writing a file in
2300 2007-09-18 6.3.5-9 Anthony <anthony@griffith...>
2301 * Bug fix for +distort in Perspective, also effected PerspectiveProjection
2303 2007-09-17 6.3.5-10 Cristy <quetzlzacatenango@image...>
2304 * Replace all InterpolatePixelColor() calls to use the ResamplePixelColor()
2306 * Map the display program pan icon window for each oversized image.
2307 * The ufraw delegate does not like quotes around the output filename.
2308 * Adjust the sensitivity of a few PerlMagick tests to pass the validation on
2309 a 64-bit FreeBSD system.
2310 * The -level option now works properly for colormapped images.
2311 * Allow Extrapolated blending of images using -blend
2312 http://netpbm.sourceforge.net/doc/extendedopacity.html
2314 2007-09-12 6.3.5-9 Anthony <anthony@griffith...>
2315 * Major Addition, Area Resampling Functions, (scaled interpolation)
2316 for pixel lookup in Distortion functions. This improves the look in
2317 areas of minification enormousally, especially in situations of infinite
2318 tiling and horizon views. All virtual pixel methods have been handled
2319 to minimise computation time involved with area resampling. To use the
2320 new function distortions need to be able to determine scaling vectors
2321 (distortion function derivitives) for correct working. All
2322 -distort methods, except Arc, uses scaled area resampling.
2323 * Improvements to perspective distort method, to include the correct
2324 differentation between the 'ground' on which the image lies, and the
2325 'sky', the color of which can be set using the -mattecolor setting
2326 (as the distortion invalid pixel color). Background color is retains
2327 for surrounding ground areas. The horizon is also correct anti-aliased
2328 and transparent colors are also allowed, allowing you to add backdrops
2329 of gradients and patterns.
