Change Logs

* 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
  * [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
- 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
- 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 (@jubalh).
  * 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
- Initial package chafa 1.0.1 for openSUSE
Version: 1.12.4-bp155.1.6
* Sun Nov 13 2022 Michael Vetter <>
- Update to 1.12.4:
  * MS Windows: Added support for Unicode command-line arguments.
  * MS Windows: Enabled support for building a DLL.
  * Improved quality of accelerated symbol picking (the default
    with -w 6 and lower), especially along sharp edges.
  * The XWD loader now supports unaligned image data, which can
    occur when the header is of an uneven length. Such images
    will no longer be rejected.
  * Bug fixes:
  - #100[1] Reading image data from stdin fails on Windows
  - #104[3] Artifacts with transparent animations on Kitty
  - #108[5] Bad interaction with lolcat
  - #112[7] Bad documentation for -c default
  - #113[9] Autogen/build fails on CentOS 7 (partial solution)

  - [unfiled] -lm should not be in pkg-config Libs: list
  - [unfiled] The --watch switch was broken with the
    introduction of --animate.
* Mon Jul 04 2022 Michael Vetter <>
- Update to 1.12.3:
  * Increased GLib minimum version to 2.26.
  * Enabled a few compiler warnings not included in -Wall -Wextra
    in order to catch more potential issues early. Also started
    using -Werror selectively.
  * Silenced deprecation warnings for older GLib APIs that we
    would like to keep using a bit longer.
  * Fix #96 Regression: Fails to build on Linux/Debian
* Mon Jul 04 2022 Michael Vetter <>
- Update to 1.12.2:
  * Made everything compile for the x86_64-w64-mingw32 target using gcc.
  * Added support for the Windows 10 Command Prompt.
  * Improved error reporting.
* 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:
    + 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 '\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
    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
  - 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.
  * 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
  * Fix 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 <bool>. On by default. Can be turned off
    to replace animations with a still frame #79.
  * New option: --center <bool> or -C <bool>. Off by default. Can
    be turned on to center images #83.
  * New options: --margin-bottom <n> and --margin-right <n>. These
    permit using all available space (with --margin-bottom 0) or some
    smaller amount #61.
  * New option: --polite <bool>. 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 <n>. 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
