gifsicle: Update to 1.95 This is a bug fix only release, and fixes a trivial memory leak that was assigned CVE-2023-44821 for some reason. Confirmed to build on FreeBSD, NetBSD, macOS, Linux by drecklypkg CI.
graphics: Replace RMD160 checksums with BLAKE2s checksums All checksums have been double-checked against existing RMD160 and SHA512 hashes
graphics: Remove SHA1 hashes for distfiles
gifsicle: Update to 1.93. ## Version 1.93 - 30.Jun.2021 * Fix security bug on certain resize operations with `--resize-method=box`. * Fix problems with colormapless GIFs.
gifsicle: Update to 1.92 ## Version 1.92 – 18.Apr.2019 * Add `--lossy` option from Kornel Lipiński. * Remove an assertion failure possible with `--conserve-memory` + `--colors` + `--careful`.
Update to 1.91. From the changelog: * Several security bug fixes with malicious GIFs. * Kill a use-after-free error reported by @junxzm1990. * Add SIMD support for resizing. When enabled this improves resize performance enormously for complex resize methods. * Add thread support for resizing. `-j[NTHREADS]` tells gifsicle to use up to NTHREADS threads to resize an input image. There are several caveats---multiple threads can be only used on unoptimized images. Thanks to Github user @wilkesybear. * Quashed several crashes and undefined behaviors. Thanks to Github users including @pornel, @strazzere, and @b0b0505. * Minor bug fixes.
Updated gifsicle to 1.88. Version 1.88 1.Jul.2015 * Fix bug where long comments were read incorrectly. Reported by kazarny. * Add --no-ignore-errors option. Version 1.87 9.Dec.2014 * Always optimize as if the background is transparent. This fixes some rare bugs reported by Lars Dieckow. * Fix --crop issue with must-be-preserved frames that are out of the crop window. Version 1.86 14.Oct.2014 * Further fix --rotate + --crop. Version 1.85 14.Oct.2014 * Greatly improve optimization time for images with many colors. * Add --no-extensions (with the s) and document those options more. * Fix bug in interaction of --resize and --rotate reported by Michał Ziemba. Version 1.84 29.Jun.2014 * Correct optimizer bug that affected GIFs with 65535 or more total colors. Reported by Jernej Simončič. Version 1.83 21.Apr.2014 * Correct bug in custom gamma values reported by Kornel Lesiński. * Update Windows build. Version 1.82 27.Mar.2014 * Correct bug in `mix` sampling method reported by Bryan Stillwell. Version 1.81 24.Mar.2014 * Correct bug in `mix` sampling method reported by Bryan Stillwell. Version 1.80 18.Mar.2014 * Bug fixes and improved error messages. Version 1.79 17.Mar.2014 * Major improvements in image scaling. Work sponsored by Tumblr via Mike Hurwitz. ** Add new resize sampling methods `mix`, `box`, `catrom`, `mitchell`, `lanczos2`, and `lanczos3`, selectable by `--resize-method`. The `catrom` filter often gives good results; the slightly faster `mix` method (a bilinear interpolator) is now the default. These new sampling methods consider all of the image's input colors when shrinking the image, producing better, less noisy output for most images. ** Add `--resize-colors`, which allows Gifsicle to enlarge the palette when resizing images. This is particularly important when shrinking images with small colormaps---e.g., shrinking a black-and-white image should probably introduce shades of gray. * Support extensions such as XMP4 in which extension packet boundaries matter. Reported by `ata4`. * Many bug fixes, especially to cropping. Thanks to Tumblr and to Bryan Stillwell, Tal Lev-Ami, "Marco," and others.
Add SHA512 digests for distfiles for graphics category Problems found with existing digests: Package fotoxx distfile fotoxx-14.03.1.tar.gz ac2033f87de2c23941261f7c50160cddf872c110 [recorded] 118e98a8cc0414676b3c4d37b8df407c28a1407c [calculated] Package ploticus-examples distfile ploticus-2.00/plnode200.tar.gz 34274a03d0c41fae5690633663e3d4114b9d7a6d [recorded] da39a3ee5e6b4b0d3255bfef95601890afd80709 [calculated] Problems found locating distfiles: Package AfterShotPro: missing distfile AfterShotPro-1.1.0.30/AfterShotPro_i386.deb Package pgraf: missing distfile pgraf-20010131.tar.gz Package qvplay: missing distfile qvplay-0.95.tar.gz Otherwise, existing SHA1 digests verified and found to be the same on the machine holding the existing distfiles (morden). All existing SHA1 digests retained for now as an audit trail.
Update to 1.78. From the changelog: * Correct an optimization bug introduced in 1.76. Reported by Tom Roostan. * Major improvements to color selection (important when reducing colormap size). Use gamma-corrected colors in selection and dithering; this makes image quality much better. Also, when reducing colors with dithering, prefer to select colors that dithering can't approximate. * Add ordered dithering modes, which avoid animation artifacts. The default ordered dithering mode (`--dither=ordered`) is a novel mode that combines some of the visual advantages of error diffusion with the artifact avoidance of ordered dithering. * Add halftone dithering (`--dither=halftone`). * gifview: Improved cache memory management for better animations. Collect memory for old frames based on an explicit --memory-limit (default 40MB). * gifview: Add `--fallback-delay` option, to specify a fallback delay for frames with delay 0. Thanks to Sung Pae. * Fix `-O2` crashes introduced with `--resize` improvements. Reported by Bryan Stillwell. * Improve `--careful` (fewer crashes). Reported by Bryan Stillwell. * Improve `-O2`: again, don't refuse to optimize images with local color tables. Reported by Bryan Stillwell. * Greatly improve `--dither` speed. * Improve `--resize` behavior: avoid animation artifacts due to different rounding decisions. Also speed it up. Reported by Bryan Stillwell. * Fix bug where `-O2` would refuse to optimize some images with local color tables, claiming that "more than 256 colors were required". What was really required is previous disposal. Reported by Bryan Stillwell. * Fix crash bugs on some combinations of `--crop` and `--resize` (prevalent on images whose first frame didn't cover the whole logical screen). Reported by Bryan Stillwell.
Changes 1.71: * Avoid rounding errors in '--resize'. * Report error when '-I' is combined with '-b'. * Frame selections also apply in batch mode.
Add RMD160 digests
Update gifsicle to 1.41. Changes unknown.
bump to 1.40
Updated to version 1.37. Changes: - DESCR has 80 culumns - whitespace 1.37: ===== - Fix bug where combining `--rotate-X' and `-O' options would cause a segmentation fault. Reported by Dan Lasley <[email protected]>. - Rearrange source tree. 1.36: ===== * Fix subscript-out-of-range error in main.c reported by Andrea Suatoni. 1.35: ===== - Fixed bug where `--crop' could cause a segmentation fault, present since 1.32 or 1.33. Reported by Tom Schumm <[email protected]>. 1.34: ===== - Fixed bug where combining `--crop' and `-O' options could corrupt output. Reported by Tom Schumm <[email protected]>. 1.33: ===== - Be more careful about time while animating. In particular, prepare frames before they are needed, so that they can be displayed exactly when required. Problem reported by Walter Harms <[email protected]>. - More warning fixes. 1.32: ===== - Add `--multifile' option handling concatenated GIF files. This is useful for scripts. For example, `gifsicle --multifile -' will merge all GIF files written to its standard input into a single animation. - More fixes for spurious background warnings. 1.31: ===== - Changed behavior of `--crop X,Y+WIDTHxHEIGHT' option when WIDTH or HEIGHT is negative. Previously, zero or negative WIDTH and HEIGHT referred to the image's entire width or height. Thus, the option `--crop 10,0+0x0' would always lead to an error, because the crop left position (10) plus the crop width (the image width) was 10 pixels beyond the image edge. The new behavior measures zero or negative WIDTH and HEIGHT relative to the image's bottom-right corner. - Changed background behavior. Hopefully the only user-visible effect will be fewer spurious warnings. - Fixed a bug that could corrupt output when optimizing images with `-O2' that had more than 256 colors. 1.30: ===== - Fixed bug in ungif code: Writing a large ungif could corrupt memory, leading eventually to bad output. This bug has been present since Gifsicle could write ungifs! Bad files and assistance provided by Jeff Brown <[email protected]>.
