47ce8e2f30- Update to 1.12.0: * The ImageMagick dependency is now optional and deprecated. Packagers are encouraged to drop the ImageMagick dependency (--without-imagemagick) and add direct dependencies on relevant image codecs. ImageMagick support will be removed in a future release. * Added image loaders for the following formats: JPEG, SVG, TIFF, WebP. Like the existing GIF, PNG and XWD loaders, these are much faster and generally safer than their ImageMagick counterparts. If ImageMagick is enabled, it will be used as a fallback. Supported image loaders will be listed in the --version output. * Implemented a 16/8 mode producing 8 colors and an additional 8 bright foreground-only colors for a total of 16 foreground and 8 background colors. When using ANSI escape sequences in symbol mode, the sequence for bold text is used to enable bright colors. This scheme corresponds to that of the IBM PC's VGA hardware text modes and was popular with terminal emulators in the late 1980s to early 2000s. With a few tweaks, output from this mode can be turned into ANSI art scene .ANS files compatible with utilities like the wonderful Ansilove[2], e.g: $ chafa -f symbols -c 16/8 -s 80 --symbols space+solid+half --fill stipple \ in.jpg | tr -d '\n' | iconv -c -f utf8 -t cp437 > out.ans $ ansilove out.ans -o out.png * New builtin Latin symbols (available with --symbols latin). This class comprises most of the symbols from the Latin-1 Supplement, Latin Extended-A and -B, IPA Extensions and Spacing Modifier Letters plus a few Latin-like symbols from other ranges, using Terminus as the reference font. The ASCII class is also a subset of this class. * Reworked ASCII symbols to be more representative of modern terminal fonts. As with the other Latin ranges, the reference font is now Terminus. * New option: --scale <n>. This takes a real number specifying the on-screen scaling factor relative to the input's pixel size, respecting the terminal

0ef534fe89- Update to 1.8.0: * Added basic support for the Kitty and iTerm2 graphics protocols. These are enabled automatically when corresponding terminal support is detected, or manually with -f kitty or -f iterm. * Implemented an 8-color mode, selectable with -c 8 * Implemented a foreground-only switch, --fg-only. This produces character art using foreground colors only, and will avoid modifying or resetting the background color. Looks best with non-contiguous symbols (e.g. ascii). * Added builtins for Japanese kana fullwidth symbols. These can now be used without loading any external fonts (try -c none --symbols wide). * Added builtins for legacy computer symbols (mainly wedges and sextant blocks). These were widely used in PETSCII and Teletext, and can be enabled using --symbols or --fill with their respective tags: legacy, wedge and sextant (@hodefoting). * Since there is a growing number of builtin symbols that may not be available everywhere, the default selection has been restricted to the widely supported block and border sets. * If possible, we now select a visually blank character from the specified symbol/fill sets instead of hardcoding ASCII space for featureless cells. One practical upshot of this is that the constant-width braille range can be used to produce consistent images even in contexts with variable-width fonts. U+2800 (BRAILLE PATTERN BLANK) will then be used in blank cells. * Improved terminal size detection when used with pipelines and redirection. This should now produce an image properly sized for your terminal: curl https://i.imgur.com/WFDEFVg.jpeg | chafa - | tee out * ChafaCanvas gained API functions for programmatically getting and setting character cell contents. These are used in a new example in tests/ncurses.c demonstrating ncurses integration. * Made --disable-rpath the default in order to simplify packaging.

6c24e3d9bc- Update to 1.6.0: * 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: - #43 Fix signal handler. - [unfiled] Crash when invalid font paths were passed on command line. - [unfiled] Small typo in fontgen's READM). - [unfiled] Bad contrast adjustment in images with transparency.

68035fd951- Update to 1.4.0: * 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.

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 * 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 (@jubalh). * Bug fixes: + [unfiled] Certain SVGs had transparency replaced with a white background (nemo). + [unfiled] -lm dependency belongs in libchafa, not frontend.
