Support connected-components:eccentricity-threshold, connected-components:major-axis-threshold, connected-components:minor-axis-threshold, connected-components:angle-threshold.
Set the alpha channel if the write mask is not enabled.
Corrected ellipse orientation when computing image moments.
Transient problem with text placement with gravity (reference https://github.com/ImageMagick/ImageMagick/issues/1633).
Support TIM2 image format (reference https://github.com/ImageMagick/ImageMagick/pull/1571).
For -magnify option, specify an alternative scaling method with -define magnify:method=method, choose from these methods: eagle2X, eagle3X, eagle3XB, epb2X, fish2X, hq2X, scale2X (default), scale3X, xbr2X.
Removed "ping_preserve_iCCP=MagickTrue;" statement that was inadvertently added to coders/png.c (reference http://imagemagick.org/discourse-server/viewtopic.php?f=3&t=32771).
Support CubicSpline resize filter. Define the lobes with the -define filter:lobes={2,3,4} (reference https://imagemagick.org/discourse-server/viewtopic.php?f=2&t=32506).
Prevent assertion failure when creating PDF thumbnail (reference https://github.com/ImageMagick/ImageMagick/issues/674).
Added a new option called 'dds:fast-mipmaps' (reference https://github.com/ImageMagick/ImageMagick/issues/558)
The mipmaps of a dds image can now be created from a list of images with -define dds:mipmaps=fromlist (reference https://imagemagick.org/discourse-server/viewtopic.php?f=2&t=30236).
Properly set image->colorspace in the PNG decoder (previously it was setting image->gamma, but only setting image->colorspace for grayscale and gray-alpha images. Reference https://imagemagick.org/discourse-server/viewtopic.php?f=3&t=32418).
Fix improper use of NULL in the JNG decoder (CVE-2017-11750, Reference https://github.com/ImageMagick/ImageMagick/issues/632).
Added "-define png:ignore-crc" option to PNG decoder. When you know your image has no CRC or ADLER32 errors, this can speed up decoding. It is also helpful in debugging bug reports from "fuzzers".
Off by one error for gradient coder (reference https://imagemagick.org/discourse-server/viewtopic.php?f=3&t=32416), https://github.com/ImageMagick/ImageMagick/issues/612).
The -monochrome option no longer returns a blank canvas (reference https://github.com/ImageMagick/ImageMagick/issues/594).
coders/png.c: fixed memory leak of quantum_info (CVE-2017-11539, reference https://github.com/ImageMagick/ImageMagick/issues/582
coders/png.c: fixed NULL dereference when trying to write an empty MNG (CVE-2017-11522, reference https://github.com/ImageMagick/ImageMagick/issues/586).
Introduce SetMagickSecurityPolicy() (MagickCore) and MagickSetSecurityPolicy() (MagickWand) to set the ImageMagick security policy (reference https://github.com/ImageMagick/ImageMagick/issues/407).
coders/png.c: Added support for a proposed new PNG chunk (zxIf, read-only) that is currently being discussed on the png-mng-misc at lists.sourceforge.net mailing list. Enable exIf and zxIf with CPPFLAGS="-DexIf_SUPPORTED -DxzIf_SUPPORTED". If exIf is enabled, only the uncompressed exIF chunk will be written and the hex-encoded zTXt chunk containing the raw Exif profile won't be written.
Renamed read_vpag_chunk_callback() function to png_user_chunk_callback() in coders/png.c
Implemented a private PNG caNv (canvas) chunk for remembering the original dimensions and offsets when an image is cropped. Previously we used the oFFs and vpAg chunks for this purpose, but this had potential conflicts with other applications that also use the oFFs chunk.
coders/png.c: Added support for a proposed new PNG chunk (exIf read-write, eXIf read-only) that is currently being discussed on the png-mng-misc at lists.sourceforge.net mailing list.
Added define 'psd:preserve-opacity-mask' to preserve the opacity mask in a PSD file.
Fixed issue where the display window was used instead of the data window when reading EXR files (reference https://imagemagick.org/discourse-server/viewtopic.php?f=3&p=137849).
New version 7.0.1-0, GIT revision 10716:b527bce:20160430.
2016-01-30 7.0.0-0 Fahad-Alsaidi & ShamsaHamed
Add support for languages that require complex text layout (reference https://github.com/ImageMagick/ImageMagick/pull/88).
2012-04-27 7.0.0-0 Anthony thyssen <A.Thyssen@griffith...>
Allow the use of set and escapes when no images in memory (unless you attempt to access per-image meta-data) Currently does not include %[fx:...] and %[pixel:...]
2012-10-05 7.0.0-0 Anthony thyssen <A.Thyssen@griffith...>
Rather than replicate 'options' into 'artifacts' make a link from image to image_info and lookup a global option if no artifact is defined.
2012-09-11 7.0.0-0 Nicolas Robidoux <nicolas.robidoux@gmail...>
sigmoidal-contrast:
Remove unnecessary initial ClampToQuantum.
2012-09-10 7.0.0-0 Nicolas Robidoux <nicolas.robidoux@gmail...>
sigmoidal-contrast:
Direct computation, without LUT;
Fix re-declaration of i (at the top, and inside a conditional).
2012-09-04 7.0.0-0 Nicolas Robidoux <nicolas.robidoux@gmail...>
Add tanh/atanh clone of legacy sigmoidal map (faster & more accurate).
2012-08-08 7.0.0-0 Nicolas Robidoux <nicolas.robidoux@gmail...>
Add final ClampToQuantum in sigmoidal colormap loop.
