1.6.1
2ad08561 · ·1.6.1 (2021-06-03) This is a bugfix release. * Add NOCONFIGURE variable to autogen.sh to skip configure (Biswapriyo Nath). * Bug fixes: github#50 SIGBUS while loading huge GIFs (reported by Grzegorz Koperwas). github#52 Produces small glitches in output with some images (reported by Sami Farin). github#54 Haiku port fails on 32bit (Luc Schrijvers). [unfiled] Exclude RTL code points that could break the output. [unfiled] Apple Terminal lacks truecolor support, so make it default to 256 colors (reported by Behdad Esfahbod). [unfiled] Fix typo affecting middle dot symbol. -
1.6.0
4662f26f · ·1.6.0 (2021-01-15) This release adds major features and important fixes to both libchafa and the chafa command-line tool. * Added support for fullwidth symbols that take up two character cells. These are common in East Asian scripts. Single-cell and double-cell symbols can be mixed, and -f symbols mode will use both if possible. * New symbol tags: Alpha, digit, alnum, narrow, wide, ambiguous, ugly, bad. "Ambiguous" symbols have uncertain widths and may render poorly in some terminals. "Ugly" denotes symbols that are unsuitable for Chafa's cell-based graphics (multicolor emoji, ideographic descriptors, etc). "Bad" is a superset of these two categories. Bad symbols are always excluded unless explicitly enabled with e.g. CHAFA_SYMBOL_TAG_BAD (--symbols +bad in the frontend). * The font loader (--glyph-file option) now does a better job with proportional fonts. * Added options for controlling lossless optimization of output. Currently, attribute reuse and character repetition (REP sequence) are implemented. * Added -O option to the frontend. This controls the optimization level. * Added a simple abstraction layer for terminal control sequences (ChafaTermInfo and ChafaTermDb). This allows for improved terminal support. * FbTerm is now supported with TERM=fbterm in the environment. * Bug fixes: github#43 Fix signal handler (reported by Markus Elfring). [unfiled] Crash when invalid font paths were passed on command line. [unfiled] Small typo in fontgen's README (Tim Gates). [unfiled] Bad contrast adjustment in images with transparency.

1.4.1
0ec6730c · ·1.4.1 (2020-04-10) This is a bugfix release. * Added configure option --disable-rpath. This allows packagers to prevent the hard-coded library search path from being embedded in the chafa command-line tool (Mo Zhou, github#39). * Added defaults for the yaft terminal. * Bug fixes: github#40 Fails to build on hurd-i386 + other i386 (reported by Mo Zhou). [unfiled] Rare failed assert with mostly transparent sixel image (reported by Reddit user spryfigure). [unfiled] Minor typo in function docstring. -
1.4.0
0d1e9da1 · ·1.4.0 (2020-04-01) This release adds major features to both libchafa and the chafa command-line tool. * Added sixel graphics support. Chafa will automatically produce sixels if the connected terminal supports it. It can also be forced using the new -f or --format flag. This is a new implementation written from the ground up to maximize throughput. * Added the --glyph-file option, which loads glyph-symbol mappings from any file format supported by FreeType (TTF, PCF, etc). This allows for custom font support and improved symbol selection. * Added the --speed option specifying animation speed. It accepts a unitless multiplier, a specific number of frames per second, or "max" for maximum throughput. * There are now two ways to assign colors to symbol cells. Formerly, this was done based on the average color of the covered area. The new default is to use the median color, which produces sharper edges, but is slightly more prone to high-frequency noise. The new option --color-extractor selects the method to employ. * When displaying multiple files, the default delay between files has been changed from three seconds to zero. Animations will still play through once. This can be overridden on the chafa command line with -d or --duration. * Minor tweaks to built-in symbols. * Performance improvements: - Halved pixel storage requirements from 64 bits to 32 bits, resulting in significant memory savings. - Now builds with -ffast-math, yielding a big speedup for DIN99d. -
1.2.1
05827591 · ·1.2.1 (2019-08-15) This minor release fixes a few bugs and improves terminal detection. * Detect kitty and mlterm virtual terminals and apply optimal defaults accordingly. * Make Automake build more strict and fix a few compatibility nits. * Bug fixes: github#30 Failed to build on hurd-i386 (found by Mo Zhou). [unfiled] Crash on certain broken GIFs.

1.2.0
f3c1a2a9 · ·1.2.0 (2019-08-04) This is a feature and performance release. * Added --dither, --dither-grain and --dither-intensity options. These allow for sub-cell dithering in quantized modes (none, 2, 16, 240 and 256). Especially beneficial when used with -p off. * Added API for ordered and diffusion-based dithering in quantization. * Added API support for multiple 8bpc pixel modes: RGB, BGR, RGBA, BGRA, ARGB, ABGR with either premultiplied or unassociated alpha channels. * Smooth scaling is now done internally, meaning libchafa consumers no longer need to prescale images. * Implemented a machine learning tool that can generate custom fonts for efficient image reproduction from a provided dataset. This is left uninstalled since it's still experimental (Mo Zhou). * Throughput improvements: - GIF animations now start playing instantly. - GIF CPU overhead reduced by 75%, peak memory use down 95%-99% (!). - XWD common case CPU overhead down 60-70%, peak memory down 70%. - Additional halving of CPU overhead in 240- and 256-color modes. - Streamlined pixel pipeline for better parallelization. * Installation instructions: - New: Guix (Guy Fleury Iteriteka). - New: openSUSE (Michael Vetter). * Bug fixes: [unfiled] Certain SVGs had transparency replaced with a white background (nemo). [unfiled] -lm dependency belongs in libchafa, not frontend. -
1.0.0
9c4470d6 · ·1.0.0 (2018-12-16) This release adds features, greatly improves performance and fixes several bugs. Programs written for the command line and libchafa interfaces in this release will be supported by future versions in the 1.y.z series without the need for modification or recompilation. * Added ability to specify "fill" symbols to use as halftone for better color approximation. This can be used to augment the regular symbol selection or to replace it (with --symbols none) for a different, purely intensity-based effect. * Improved preprocessing in 2-color and 16-color modes. This is optional (default: on) and consists of a contrast boost and, for the 16-color mode, an additional saturation boost. The new implementation lives in libchafa and does not rely on ImageMagick. It is multithreaded, and due to its specialized nature, much faster. * Added --watch option to continuously monitor a file. * Added more symbols: - Most of the ASCII range. - Braille range (github#2, thanks to Adam Borowski). - Miscellaneous math and scanline symbols. - More geometric symbols (black circle, triangles) (Mo Zhou). * Throughput improvements: - Fast symbol candidate set reduction by median cut. - Parallel processing with threads. - Prescaling using bilinear interpolation instead of lanczos. * Installation instructions: - New: Arch (github#12, Felix Yan). - New: Debian testing/unstable (github#9, Mo Zhou). - New: Fedora (github#14, Ricardo Arguello). - Mention missing dependency for Debian (github#13, @medusacle). * Bug fixes: github#1 -c none produces pointless \e[0m after every line (found by Adam Borowski). github#3 Compile error (found by Lajos Papp). github#4 AM_PROG_LIBTOOL is obsolete, replace it with LT_INIT (Robert-André Mauchin). github#5 Port chafa to i386 architecture (Mo Zhou). github#7 Chafa should not return an error when being asked for --version (Mo Zhou). github#10 Fix detection of MagickWand methods (Felix Yan). github#11 ImageMagick 7 support (found by Felix Yan). github#21 chafa.c:547: pointless assignment (found by @dcb314). -
