ImageMagick: Changelog

2010-12-26 6.6.6-8 Cristy <quetzlzacatenango@image...>

-posterize fails with more than 40 levels (reference http://www.imagemagick.org/discourse-server/viewtopic.html?f=3&t=17741).
Add support for the MacPaint image format.
Eliminate spurios 'invalid colormap index' exception for 16-bit SGI images (bug report by steven.sittser@fligh...).
Fix user data length for the CIN image format.

2010-12-21 6.6.6-7 Glenn Randers-Pehrson <glennrp@image...>

Use a clone instead of the main image in coders/png.c, so the image can still be used later on without being affected by changes made by the PNG encoder.
Added PNG:exclude-chunk and PNG:include-chunk defines.
Revised the -strip option so it behaves as though "-define PNG:include-chunk=none,gama" had appeared on the commandline.
Avoid writing PNG ancillary chunks in the PNG/MNG/JNG encoder while generating the alpha channel for a JNG image.

2010-12-21 6.6.6-7 Anthony Thyssen <A.Thyssen@griffith...>

Removed the forced interpolation setting in AcquireResampleFilterThreadSet It prevented user defined interpolation settings for -clut, and possibly other usage.

2010-12-17 6.6.6-6 Chris Madison <madisonblu@gmail...>

Add LZMA compression support to ImageMagick.

2010-12-17 6.6.6-6 Glenn Randers-Pehrson <glennrp@image...>

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

2010-12-14 6.6.6-6 Cristy <quetzlzacatenango@image...>

-format "%[fx:u.p{5,5}]" no longer reports parse exception (reference http://www.imagemagick.org/discourse-server/viewtopic.html?f=3&t=17678).

2010-12-10 6.6.6-5 Glenn Randers-Pehrson <glennrp@image...>

Make the PNG encoder always rebuild the palette, to avoid losing transparency when it is out of sync with the pixel data (reference http://www.imagemagick.org/discourse-server/viewtopic.html?f=3&t=17655).
Eliminated CompressColormapTransFirst() since the palette is already compressed and sorted by opacity now when it's recreated.

2010-12-10 6.6.6-5 Cristy <quetzlzacatenango@image...>

Account for virtual canvas for the -flip / -flop options (reference http://www.imagemagick.org/discourse-server/viewtopic.html?f=1&t=17626).
Also for -transpose and transverse options
Support -metric fuzz option.

2010-12-09 6.6.6-4 Anthony Thyssen <A.Thyssen@griffith...>

Replace IsMagickColorSimilar() which provides the Fuzz Factor threshold function. Note function does not calculate 'distance' in total but short-circuits when threshold is reached for faster processing.
Ordered Dithered handling of Alpha channel was incorrect - fixing Bug was introduced v6.6.5-6

2010-12-03 6.6.6-3 Glenn Randers-Pehrson <glennrp@image...>

2010-11-23 6.6.6-0 Cristy <quetzlzacatenango@image...>

The policy.xml sets not-to-exceed resource values (e.g. policy memory limit 1GB, -limit 2GB exceeds policy maximum so memory limit is 1GB).
Support NCC (normalized cross correlation) compare metric.

2010-11-21 6.6.5-10 Cristy <quetzlzacatenango@image...>

Fix PNG coder compile error when HDRI is enabled.

2010-11-17 6.6.5-9 Glenn Randers-Pehrson <glennrp@image...>

Many of the problems with the PNG encoder have been fixed (reference http://www.imagemagick.org/discourse-server/viewtopic.html?f=3&t=16490).
The "-type Optimize" option is now deprecated. If present, it is treated by the PNG encoder the same as if the type were undefined. Optimization is now always performed. No other formats used the "type Optimize" option.
Merged redundant code into LosslessReduceDepth() function in the PNG codec.

2010-11-14 6.6.5-9 Cristy <quetzlzacatenango@image...>

Allow numeric characters in the XPM basename (reference http://www.imagemagick.org/discourse-server/viewtopic.html?f=3&t=17385).

2010-10-29 6.6.5-4 Glenn Randers-Pehrson <glennrp@image...>

Revised PNG palette optimization
Added some debug logging in coders/png.c.

2010-10-28 6.6.5-3 Nicolas Robidoux <nicolas.robidoux@gmai...>

Use #pragma omp master for dumping single threaded debugging information (single caused a fault).
Add support for -evaluate exp.

2010-10-12 6.6.5-0 Anthony Thyssen <A.Thyssen@griffith...>

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

2010-10-10 6.6.5-0 Cristy <quetzlzacatenango@image...>

Patch for DrawableRotation() and DrawableTranslation() (reference http://www.imagemagick.org/discourse-server/viewtopic.html?f=3&t=17246).
The webp format requires the webpconv delegate program (experimental).

2010-10-05 6.6.5-0 Anthony Thyssen <A.Thyssen@griffith...>

Replaced "Robidoux" with Cubic 'Keys' filter that is near equivelent to the previous sharped "Lanczos2D" filter. (C=0.31089212245300069) This also is very similer to a Mitchell filter but specifically designed for EWA use and is the new default filter for Distorting Images.
Original sharpened Lanczos2D filter now called "Lanczos2Dsharp"

2010-10-08 6.6.4-10 Jerry Gay <jerry.gay@gmail..>

Autodetect file type support in Makefile.PL to prevent test failures

2010-10-05 6.6.4-10 Anthony Thyssen <A.Thyssen@griffith...>

Added new filter 'Lanczos2D' a 2-lobe Lanczos as defined by Andreas Gustafsson in his thesis "Interactive Image Warping" (page 24) http://www.gson.org/thesis/warping-thesis.pdf
Added filter "Robidoux" which is a slightly sharpened version of the "Lanczos2D" filter (blur=0.958033808) specifically designed to be less 'blurry' for horizontal and vertical lines in no-op distortions.

2010-10-05 6.6.4-10 Cristy <quetzlzacatenango@image...>

Add support for "pattern:vertical2" and "pattern:horizontal2".

Don't permit access to pixels when pinging an image (reference http://www.imagemagick.org/discourse-server/viewtopic.html?f=3&t=17194).

2010-10-02 6.6.4-9 Anthony Thyssen <A.Thyssen@griffith...>

Added sqrt(2) blurring default for Gaussian Filter if used as a Cylindrical EWA filter. This resulted removing the last aliasing issue that was present in tests for Gaussian EWA resampling. Of course it is still a very blurry filter for default use in EWA.
Adjusted Variable Mapping Blur Composition so user arguments actual relate properly to the sigma of the blur for a maximum mapping value.
Fix horizon anti-alising for output-scaled perspective distortions.
'Bessel' filter is now offically and more accuritally named 'Jinc' however 'Bessel' while not visible as a filter option can still be used as an internal alias for 'Jinc'.

2010-09-28 6.6.4-8 Nicolas Robidoux <nicolas.robidoux@gmai...>

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

2010-09-28 6.6.4-8 Cristy <quetzlzacatenango@image...>

Temporary files not always deleted (reference http://www.imagemagick.org/discourse-server/viewtopic.html?f=2&t=15960).

2010-09-28 6.6.4-8 Anthony Thyssen <A.Thyssen@griffith...>

Bug fix for -filter point distorts (occasional generating black pixels)

2010-09-27 6.6.4-8 Nicolas Robidoux <nicolas.robidoux@gmai...>

Simplified the ClampUpAxes code, the use of its outputs, its comments, and credited Craig DeForest for the "clamp singular values" idea.
No reason to have "insane" precision Sinc in resize.c: Use the 1.2e-12 max. abs. relative error version for Q64 as well as Q32.

2010-09-27 6.6.4-8 Anthony Thyssen <A.Thyssen@griffith...>

Replace the blurry "High Quality EWA" technique with a 'Clamped EWA' for Distort Resampling. This makes -distort a whole lot nicer and allows for the use of better cylindrical filters.

2010-09-26 6.6.4-7 Anthony Thyssen <A.Thyssen@griffith...>

Fix Point filter for ResizeImage() caused by support limiting the Box weighting function.

2010-09-26 6.6.4-6 Cristy <quetzlzacatenango@image...>

2010-09-24 6.6.4-6 Nicolas Robidoux <nicolas.robidoux@gmai...>

Now that MagickPIL is a MagickRealType, some casts are unneeded.

2010-09-21 6.6.4-6 Cristy <quetzlzacatenango@image...>

Do not break words if caption size is absolute (reference http://www.imagemagick.org/discourse-server/viewtopic.html?f=1&t=17123).
Don't define HAVE_THREADS for --without-threads configure script option.

2010-09-20 6.6.4-5 Nicolas Robidoux <nicolas.robidoux@gmai...>

Modified "magick/resize.c" so that MagickPIL is a MagickRealType number. Some computations were needlessly done in long double precision because PIL forced an automatic upcast wherever it appeared. Changed its name to MagickREALTYPEPI. <- This was later reverted back to MagickPIL.
Modified "magick/resize.c" so that Bohman uses one trig call + one sqrt call instead of two trig calls.

2010-09-20 6.6.4-5 Anthony Thyssen <A.Thyssen@griffith...>

modified "magick/resample.c" to allow use of either EWA or HQEWA (default)
Removed LanczosFast from supported filters (SincFast*SincFast is faster)

2010-09-19 6.6.4-5 Cristy <quetzlzacatenango@image...>

If IPTC profile is not embedded in an 8bim resource, declare it IPTC rather than 8BIM.

TIFF tile geometry must be divisible by 16.

2010-09-15 6.6.4-2 Anthony Thyssen <A.Thyssen@griffith...>

Rename of SincPolynomial to SincFast for easier user understanding
Ditto for LanczosChebyshev to LanzcosFast

2010-09-14 6.6.4-2 Anthony Thyssen <A.Thyssen@griffith...>

Switch default resize filters to using the faster SincPolynomial filter by default internally. However 'Sinc' will still use the Trigonometric function, and can be used to assign the trig version of Sinc() to filters using the filter expert options.
The default filter for 'distort' was found to be a very blurry inaccurate filter function. It was removed and replaced with a correct Gaussian filter (as used by resize)
Added a switch so that "-interpolate filter" will force the use of a cylindrical filter for ALL pixels in distorted images. That is you can use that switch to use a cylindrical filter even for images that are being enlarged by the distortion. However EWA is still currently using a fixed 2.0 sampling radius. This switch complements the use of "-filter point" which turns off EWA filters in favor of interpolation for all pixels in a distorted image. BOTH switches should not be used together.
A bug in the support radius of the EWA resampling function was found, now that correctly defined resize filters are being used. Suddenly Normal Gaussian distortions are not so blurry, and tests with distortions of the 'Rings' image show extremely good and clear results, with only minimal blurring. The filter 'blur' expert option can be used to adjust this further.

2010-09-13 6.6.4-2 Cristy <quetzlzacatenango@image...>

Don't negate the geometry offset for the -extent option.

2010-09-09 6.6.4-1 Cristy <quetzlzacatenango@image...>

The RGBO format is now listed as a supported format.

2010-09-07 6.6.4-1 Anthony Thyssen <A.Thyssen@griffith...>

Added the Nicolas Robidoux and Chantal Racette Lanczos resize filter function as "LanczosChebyshev" as faster alternative to Lanczos.
Re-code Nicolas Robidoux and Chantal Racette Polynomial Approximation of the Sinc Trigonometric resize filter, as a proper filter to allow direct comparision and speed testing of the filter.
Expanded the "-set option:filter:verbose 1" output, so as to also include the actual functions and other values that were used to create the filter.

2010-09-02 6.6.4-0 el_supremo <digipete@shaw...>

Third Re-write of MorphologyApply() to better handle compound methods.
Implemented -set option:morphology:compose for merging results of multiple kernels. "None" means re-iterate results with next kernel. While "Undefined" means to use the internal default for a method.

2010-05-05 6.6.1-6 Anthony Thyssen <A.Thyssen@griffith...>

Rename of "Add" and "Subtract" compositions to "ModulusAdd" and "ModulusSubtract" for more clarity of there functions. Old names will continue to work as expected.
Fix "Minus", "ModulusAdd", and "ModulusSubtract" to follow normal SVG 'Over' blending specifications, (see next for override) Note that this does NOT include the "Plus" composition method which has SVG definition for it to use a 'Plus' blending rather than 'Over' blending.

By default mathematical compositions work as per SVG definition. That is the results are synchronized with 'Over' alpha-blending (except "Plus" which uses 'plus' alpha-blending).

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

Bug Fix for transparency handling in Composite Variable Blur
Addition of -auto-level and -auto-gamma image enhancements (under trial not yet final)
Addition of a special -channel flag 'sync' which means that the specified channels are to be modified together by the same amount. The flag is enabled by default. This replaces the current 'channels not modified' type handling thought IM.
Modified -channel parsing to continue looking for words, after handling any shorthand channel options. For example: -channel RGB,sync

Generate a proper file path for -path @filelist.txt (reference http://www.imagemagick.org/discourse-server/viewtopic.html?f=1&t=13671).

2009-05-01 6.5.2-0 Glenn Randers-Pehrson <glennrp@image...>

Accept "-define png:bit-depth=value" and "-define png:color-type=value" options. This is work-in-progress with the objective of being able to precisely specify the type of PNG file to be written. The previously-used internal attribute "png:bit-depth" that was used to communicate between the PNG writer and the JNG writer is changed to "png:bit-depth-written". This feature needs testing. It is important to note that this feature cannot be used to force the PNG to use a bit-depth or color-type that does not losslessly represent the image. You can, however, cause the writer to use a larger depth or to use the RGB colorspace when grayscale or indexed would have been sufficent.

2009-05-01 6.5.1-10 Anthony Thyssen <A.Thyssen@griffith...>

Fixed the Rmin usage in Depolar and Polar distortions
The 6th argument (Ato) for Polar/Depolar is now optional and defaults to Afrom + 360 degrees (or a fill circle from the given start angle)

Refrain from modifying image struct members (color, depth, matte) while writing PNG datastreams.

2009-04-21 6.5.1-4 Glenn Randers-Pehrson <glennrp@image...>

Sometimes the PNG8: format would produce 1-, 2-, or 4-bit PNG datastreams. Now it always produces 8-bit datastreams as users probably expect.

2009-04-21 6.5.1-4 Glenn Randers-Pehrson <glennrp@image...>

Suppressed "shadowed declaration" warnings in coders/jpeg.c and coders/png.c that are triggered by "-Wshadow" gcc compiler flag.

2009-04-11 6.5.1-2 Anthony Thyssen <A.Thyssen@griffith...>

Rename existing "Bilinear" distortion as "BilinearReverse"
Added forward mapped bilinear distort as "BilinearForward"
The "Bilinear" distort is temporarily obsoleted but will eventually be added as a "BilinearReverse" and "BilinearForward" combination mapping though a unit square.
Sparse Gradient internally uses "BilinearReverse" for its "Bilinear" gradient function as that method is the direct use of such equations.

Fix old -clut bug for re-coloring gray images using transparent and semi-transparent colors.

2009-02-22 6.4.9-7 Rick Mabry <rick.mabry@anony...>

Changes have been made to scores of the files that generate the documentation. The most noticeable cosmetic changes are to the command-line examples and command-line snippets, which now have a new look: dark blue boxes with white/yellow text to indicate sample input/output. Inclusion of current version and release dates in appropriate places are now automatically generated. Also, many changes have been made to begin to bring the pages into strict W3C compliance with respect to both HTML and CSS.

2007-10-12 6.3.6-2 Anthony <anthony@griffith...>

Least Squares coordinate handling added for -distort methods Affine, Perspective, Bilinear. This allows for more than the minimal number of coordinates to be used to 'fit' a distortion function to an image. This addition will allow the use of image registration to generate panarama overviews and better geographical coordinate correction.
Cosolidated the simular methods FlattenImage() and MosaicImage() into a new layers function MergeImageLayers() method, adding 'flatten' and 'mosaic' layer methods.
Addition of another simular layers method 'merge' which 'unlocks' the normal flatten/mosaic layer merger from the origin, The resulting image will have a virtual canvas of minimal size with an offset. Also images with negative offsets will not be clipped by the 'merge' form of the command. This was created for better layering of distorted images, such as panarama overlays.
Bug fix in handling transparency for EWA resampling.
Access to Resize Filter Functions from resize.c (for resample.c) with posible future filter sources... Acquire/Destory/Call ResizeFilter()

2007-09-12 6.3.5-9 Anthony <anthony@griffith...>

Major Addition, Area Resampling Functions, (scaled interpolation) for pixel lookup in Distortion functions. This improves the look in areas of minification enormousally, especially in situations of infinite tiling and horizon views. All virtual pixel methods have been handled to minimise computation time involved with area resampling. To use the new function distortions need to be able to determine scaling vectors (distortion function derivitives) for correct working. All -distort methods, except Arc, uses scaled area resampling.
Improvements to perspective distort method, to include the correct differentation between the 'ground' on which the image lies, and the 'sky', the color of which can be set using the -mattecolor setting (as the distortion invalid pixel color). Background color is retains for surrounding ground areas. The horizon is also correct anti-aliased and transparent colors are also allowed, allowing you to add backdrops of gradients and patterns.
