* Mon Jun 20 2022 Michael Vetter - Update to 1.12.1:
* Increased GLib minimum version to 2.20.
* Added 12 new test inputs, including bad inputs to handle gracefully.
* Added a few symbols to API documentation that were accidentally left out.
* Bug fixes: + huntr.dev CVE-2022-2061: Out-of-bounds read in libnsgif\'s lzw_decode() + [unfiled] Undefined behavior in libnsgif due to uninitialized frame fields. + [unfiled] Signed integer overflow in chafa_pack_color(). + [unfiled] Integer overflow in normalization pass on some images. + [unfiled] Potential unaligned access with corrupt XWD images. + [unfiled] Integer overflow in quantization on some images. + [unfiled] Calculating offset from NULL pointer in LodePNG.
* Mon Jun 06 2022 Michael Vetter - 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 \'\
\' | 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 . This takes a real number specifying the on-screen scaling factor relative to the input\'s pixel size, respecting the terminal size. The special argument \'max\' will fit the output to the terminal. The defaults are 1.0 for iTerm, Kitty and sixels, and 4.0 for symbols. #84
* Deprecated option: --zoom. Use --scale max instead.
* Added a battery of simple tests that can be run with make check.
* Made configure friendlier. It\'s now more lenient with dependencies, and the summary is more detailed and colorized if possible.
* Bug fixes: - #62 Too big alloc on bogus terminal dimensions - huntr.dev: Null pointer dereference caused by calling post_func on unused batch entries - [unfiled] Small memory leaks when using iTerm and Kitty formats. - [unfiled] Wide symbol coverages leaked in symbol map destructor. - [unfiled] No error code if files failed to load.
* Thu May 05 2022 Michael Vetter - Update to 1.10.3:
* Improved input validation in the XWD loader.
* huntr.dev: Buffer over-read when compiled with -O0 or non-x86 target
* Mon Apr 25 2022 Michael Vetter - Update to 1.10.2:
* Added disclosure guidelines in SECURITY.md
* Fix huntr.dev: Null pointer dereference in libnsgif with crafted GIF file
* [unfiled] File magic would not effectively rule out internal loaders.
* [unfiled] Very big images could cause absurd allocation requests triggering an abort in the loader.
* Mon Apr 04 2022 Michael Vetter - Update to 0.10.1:
* #87 Garbled last row of pixels on some images
* [unfiled] Correctly label new functions since 1.10
* Mon Mar 21 2022 Michael Vetter - Update to 0.10.0:
* New option: --animate . On by default. Can be turned off to replace animations with a still frame #79.
* New option: --center or -C . Off by default. Can be turned on to center images #83.
* New options: --margin-bottom and --margin-right . These permit using all available space (with --margin-bottom 0) or some smaller amount #61.
* New option: --polite . On by default. Can be turned off to correct issues caused by previous terminal state (e.g. no sixel scrolling) and improve presentation (e.g. by temporarily hiding the cursor). This can leave the terminal in an altered state, which is somewhat rude.
* New option: --threads . Allows manually specifying the number of threads to use. Defaults to one per detected logical CPU core.
* When invoked with redirected input and no arguments, act like a filter as if invoked with -.
* If input or output is being redirected, default to playing animations only once instead of looping forever. This can be overridden with -d inf.
* Replaced obsolete Autoconf macros.
* Improved image loaders: + GIF: Load GIF87a images as well as GIF89a. + PNG: Add an internal copy of LodePNG, bypassing ImageMagick. This improves performance and helps with eventually phasing out the latter. + XWD: Support images generated by convert.
* Improved terminal support: + Contour: Enable sixel support. + foot: Open-ended TERM string matching. + Konsole: Enable sixel support. + WezTerm: Enable sixel support.
* Bug fixes: + #76 Smolscale uses too much stack space. + #81 Chafa --version is returned to stderr, not stdout. + [unfiled] Potential memory overrun when using Floyd-Steinberg dithering in symbols mode. + [unfiled] iTerm2 compatibility issue with WezTerm and possi
* Wed Sep 01 2021 Michael Vetter - 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 (AATThodefoting).
* 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.
* Added a HACKING file featuring a much needed release checklist.
* Improved terminal support: + Ctx will now use optimizing REP sequences at high -O levels. + foot now defaults to sixels. + iTerm2 now defaults to the iTerm2 protocol. + Kitty now defaults to the Kitty protocol. + st now defaults to truecolor symbols.
* Bug fixes: + #44 Missing error handling on stdout writes. + [unfiled] Solid symbols erroneously replaced by fill in FGBG mode. + [unfiled] Integer formatter was not using fast path for 8-bit values.
* Mon Jun 07 2021 Michael Vetter - Update to 1.6.1:
* Add NOCONFIGURE variable to autogen.sh to skip configure Bug fixes:
* #50 SIGBUS while loading huge GIFs
* #52 Produces small glitches in output with some images
* #54 Haiku port fails on 32bit
* [unfiled] Exclude RTL code points that could break the output.
* [unfiled] Apple Terminal lacks truecolor support, so make it default to 256 colors
* [unfiled] Fix typo affecting middle dot symbol.
* Fri Jan 15 2021 Michael Vetter - 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.
* Sun Apr 12 2020 Michael Vetter - Update to 1.4.1:
* 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, #39).
* Added defaults for the yaft terminal. Bug fixes:
* #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.
* Thu Apr 02 2020 Michael Vetter - 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.
* Wed Mar 04 2020 Michael Vetter - Update to 1.2.2:
* Fix #34 Cannot compile example
* Sat Aug 24 2019 Jan Engelhardt - Update descriptions.- Avoid double-shipping documentation, and make docs noarch.
* Tue Aug 20 2019 mvetterAATTsuse.com- Update to 1.2.1:
* Detect kitty and mlterm virtual terminals and apply optimal defaults accordingly
* Make Automake build more strict and fix a few compatibility nits
* Fix #30 - Failed to build on hurd-i386
* Fix crash on certain broken GIFs
* Mon Aug 05 2019 mvetterAATTsuse.com- Update to 1.2.0:
* 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
* 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 (AATTjubalh).
* Bug fixes: + [unfiled] Certain SVGs had transparency replaced with a white background (nemo). + [unfiled] -lm dependency belongs in libchafa, not frontend.
* Fri Feb 08 2019 mvetterAATTsuse.com- Initial package chafa 1.0.1 for openSUSE
