|
|
|
|
- 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

|
|
|
|
- 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.
|
|
* 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.

|
|
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
|

|
|
|
|
- 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 21:17:36 UTC 2020 - Michael Vetter <mvetter@suse.com>
|
|
|
|
- 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 2 08:08:26 UTC 2020 - Michael Vetter <mvetter@suse.com>
|
|
|
|
- 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.

|
|
|
|
- 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
|

|
Mon Aug 5 07:10:33 UTC 2019 - mvetter@suse.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 (@jubalh).
|
|
* Bug fixes:
|
|
+ [unfiled] Certain SVGs had transparency replaced with a white background (nemo).
|
|
+ [unfiled] -lm dependency belongs in libchafa, not frontend.
