* 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)
- huntr.dev: Uncontrolled memory allocation in lodepng
- [unfiled] -lm should not be in pkg-config Libs: list
- [unfiled] The --watch switch was broken with the
introduction of --animate.

* 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
- 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.
OBS-URL: https://build.opensuse.org/package/show/graphics/chafa?expand=0&rev=33
* Increased GLib minimum version to 2.20.
* Added 12 new test inputs, including bad inputs to handle gracefully.

* 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
OBS-URL: https://build.opensuse.org/package/show/graphics/chafa?expand=0&rev=29
* 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.
OBS-URL: https://build.opensuse.org/package/show/graphics/chafa?expand=0&rev=25
* 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.
OBS-URL: https://build.opensuse.org/package/show/graphics/chafa?expand=0&rev=19
* 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.
OBS-URL: https://build.opensuse.org/package/show/graphics/chafa?expand=0&rev=16
* 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.
OBS-URL: https://build.opensuse.org/package/show/graphics/chafa?expand=0&rev=14
* 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.
OBS-URL: https://build.opensuse.org/package/show/graphics/chafa?expand=0&rev=12
* 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.
OBS-URL: https://build.opensuse.org/package/show/graphics/chafa?expand=0&rev=10
* 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
OBS-URL: https://build.opensuse.org/package/show/graphics/chafa?expand=0&rev=4
* 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.
