## 2.4.4
|
|||
|
|
|
|||
|
|
### Fixed
|
|||
|
|
|
|||
|
|
* Rendering of bitmap fonts with Freetype >= 2.11
|
|||
|
|
(https://codeberg.org/dnkl/fcft/issues/29).
|
|||
|
|
|
|||
|
|
|
|||
|
|
## 2.4.3
|
|||
|
|
|
|||
|
|
### Fixed
|
|||
|
|
|
|||
|
|
* Bitmap/aliased font glyphs being mirrored on big-endian
|
|||
|
|
architectures.
|
|||
|
|
* Color font glyphs having wrong colors on big-endian architectures.
|
|||
|
|
* Crash when destroying a font that failed to load (typically happens
|
|||
|
|
when there are no fonts available at all).
|
|||
|
|
|
|||
|
|
|
|||
|
|
## 2.4.2
|
|||
|
|
|
|||
|
|
### Fixed
|
|||
|
|
|
|||
|
|
* Rare crash when one thread was doing a glyph cache lookup, while
|
|||
|
|
another was resizing the cache.
|
|||
|
|
|
|||
|
|
|
|||
|
|
## 2.4.1
|
|||
|
|
|
|||
|
|
### Changed
|
|||
|
|
|
|||
|
|
* Log messages are now printed to stderr instead of stdout.
|
|||
|
|
* `fcft_grapheme_rasterize()` now sets a minimum grapheme column count
|
|||
|
|
of 2 when the cluster ends with an Emoji variant selector (codepoint
|
|||
|
|
0xFE0F).
|
|||
|
|
|
|||
|
|
|
|||
|
|
### Fixed
|
|||
|
|
|
|||
|
|
* Compilation error when fallback definition for `FCFT_EXPORT` was used
|
|||
|
|
in `meson.build`.

## 2.4.0
|
|||
|
|
|
|||
|
|
### Added
|
|||
|
|
|
|||
|
|
* Example program. Very simple bare bones Wayland program that renders
|
|||
|
|
a user provided string with user configurable fonts and colors. No
|
|||
|
|
proper error checking etc. To build, configure meson with
|
|||
|
|
`-Dexamples=true`.
|
|||
|
|
* `fcft_log_init()`. This function enables, and configures logging in fcft.
|
|||
|
|
* `fcft_text_run_rasterize()`: new API that uses HarfBuzz to shape a
|
|||
|
|
text run (i.e. a whole string). Note that HarfBuzz is (still) an
|
|||
|
|
**optional** dependency, see
|
|||
|
|
[README](README.md#user-content-building).
|
|||
|
|
* `fcft_text_run_destroy()`: new API that frees a rasterized text-run.
|
|||
|
|
* `FCFT_CAPABILITY_TEXT_RUN_SHAPING` added to `fcft_capabilities()`.
|
|||
|
|
* `antialias` and `subpixel` members to `struct fcft_font`.
|
|||
|
|
|
|||
|
|
|
|||
|
|
### Changed
|
|||
|
|
|
|||
|
|
* fcft logging must now be enabled explicitly (see `fcft_log_init()`).
|
|||
|
|
* Internal logging functions are no longer exported by the shared library.
|
|||
|
|
* The pixel size passed from FontConfig to FreeType is now rounded
|
|||
|
|
instead of truncated (https://codeberg.org/dnkl/foot/issues/456).
|
|||
|
|
|
|||
|
|
|
|||
|
|
### Fixed
|
|||
|
|
|
|||
|
|
* Internal logging functions have been renamed, from generic `log_*`
|
|||
|
|
names to fcft specific `fcft_log_` names.
|
|||
|
|
* Apply pixel-size fixup to glyphs’ advance width/height, but **only**
|
|||
|
|
if we estimated the fixup ourselves (otherwise the advance
|
|||
|
|
width/height is already scaled).
|
|||
|
|
|
|||
|
|
|
|||
|
|
## 2.3.3
|
|||
|
|
|
|||
|
|
### Fixed
|
|||
|
|
|
|||
|
|
* Cloned fonts not being properly freed in library destructor.
|
|||
|
|
|
|||
|
|
|
|||
|
|
## 2.3.2
|
|||
|
|
|
|||
|
|
### Added
|
|||
|
|
|
|||
|
|
* Limited support for _"fontfeatures_" . fcft is still not a layout
|
|||
|
|
engine, but with this we can support e.g. _stylistic sets_
|
|||
|
|
(HarfBuzz-enabled builds only).
|
|||
|
|
|
|||
|
|
|
|||
|
|
### Deprecated
|
|||
|
|
|
|||
|
|
* `tags` argument in `fcft_grapheme_rasterize()`. It is now being
|
|||
|
|
ignored, and will be removed in a future release.
|
|||
|
|
|
|||
|
|
|
|||
|
|
### Fixed
|
|||
|
|
|
|||
|
|
* Hang in library destructor when system has no fonts installed
|
|||
|
|
(https://codeberg.org/dnkl/foot/issues/174).

## 2.3.1
|
|||
|
|
|
|||
|
|
### Fixed
|
|||
|
|
|
|||
|
|
* `fcft_grapheme_rasterize()` now makes use of the optional
|
|||
|
|
`tags`. These were previously ignored.
|
|||
|
|
* Compilation error when text shaping was disabled.
|
|||
|
|
|
|||
|
|
|
|||
|
|
## 2.3.0
|
|||
|
|
|
|||
|
|
### Added
|
|||
|
|
|
|||
|
|
* `fcft_set_scaling_filter()`: new API that lets the calling
|
|||
|
|
application configure the filter to use when downscaling bitmap
|
|||
|
|
fonts (https://codeberg.org/dnkl/fcft/issues/9).
|
|||
|
|
* `fcft_grapheme_rasterize()`: new API that uses HarfBuzz to shape a
|
|||
|
|
grapheme cluster. Note that HarfBuzz is an **optional** dependency,
|
|||
|
|
see [README](README.md#user-content-building).
|
|||
|
|
|
|||
|
|
|
|||
|
|
### Changed
|
|||
|
|
|
|||
|
|
* Increased timeout in tests, from 4s (the default), to 60s
|
|||
|
|
(https://codeberg.org/dnkl/foot/issues/120).
|
|||
|
|
|
|||
|
|
|
|||
|
|
## 2.2.7
|
|||
|
|
|
|||
|
|
### Changed
|
|||
|
|
|
|||
|
|
* Use lanczos3 filtering when downscaling bitmap fonts. This improves
|
|||
|
|
the quality of e.g. color emoji fonts.
|
|||
|
|
|
|||
|
|
|
|||
|
|
### Fixed
|
|||
|
|
|
|||
|
|
* Compilation with `-pedantic`
|
|||
|
|
|
|||
|
|
|
|||
|
|
## 2.2.6
|
|||
|
|
|
|||
|
|
### Fixed
|
|||
|
|
|
|||
|
|
* Set LCD filter. This fixes **severe** color fringes when FreeType
|
|||
|
|
has been built with `FT_CONFIG_OPTION_SUBPIXEL_RENDERING` (i.e. the
|
|||
|
|
old ClearType-style subpixel rendering, instead of the newer Harmony
|
|||
|
|
LCD rendering).
|
|||
|
|
|
|||
|
|
|
|||
|
|
## 2.2.5
|
|||
|
|
|
|||
|
|
### Changed
|
|||
|
|
|
|||
|
|
* `fcft_glyph_rasterize()`: improved performance in threaded
|
|||
|
|
applications by guarding the glyph cache with an _rwlock_ instead of
|
|||
|
|
a _mutex_.
|
|||
|
|
|
|||
|
|
|
|||
|
|
### Fixed
|
|||
|
|
|
|||
|
|
* fcft now checks for memory allocation failures.
|
|||
|
|
* Compilation errors in 32-bit builds.
|
|||
|
|
|
|||
|
|
|
|||
|
|
## 2.2.4
|
|||
|
|
|
|||
|
|
### Added
|
|||
|
|
|
|||
|
|
* Unicode license file, for `UnicodeData.txt`
|
|||
|
|
|
|||
|
|
|
|||
|
|
## 2.2.3
|
|||
|
|
### Added
|
|||
|
|
|
|||
|
|
* Missing [LICENSE](LICENSE) file
|
|||
|
|
* [LICENSE](LICENSE), [README.md](README.md) and
|
|||
|
|
[CHANGELOG.md](CHANGELOG.md) are now installed to
|
|||
|
|
`${datadir}/doc/fcft`.
|
|||
|
|
|
|||
|
|
|
|||
|
|
### Fixed
|
|||
|
|
|
|||
|
|
* Assertion in debug builds when resizing the glyph cache
|
|||
|
|
|
|||
|
|
|
|||
|
|
## 2.2.2
|
|||
|
|
|
|||
|
|
### Fixed
|
|||
|
|
|
|||
|
|
* `fcft_kerning()` was not threadsafe
|
|||
|
|
* Rare crash in `fcft_glyph_rasterize()` caused by a race between a
|
|||
|
|
successful glyph cache lookup and a glyph cache resize.
|
|||
|
|
|
|||
|
|
|
|||
|
|
## 2.2.1
|
|||
|
|
|
|||
|
|
### Changed
|
|||
|
|
|
|||
|
|
* Color bitmap glyphs with a pixel-size fixup factor other than 1.0
|
|||
|
|
are now pre-scaled. Previously, fcft would only set a pixman scale
|
|||
|
|
transform on the glyph, causing actual scaling to occur **every**
|
|||
|
|
time the glyph was blended. This improves the performance when
|
|||
|
|
rendering color emojis.
|
|||
|
|
|
|||
|
|
|
|||
|
|
## 2.2.0
|
|||
|
|
|
|||
|
|
### Changed
|
|||
|
|
|
|||
|
|
* Internal representation of the primary and fallback fonts.
|
|||
|
|
* Do not load a fallback font if it does not contain the requested glyph.
|
|||
|
|
|
|||
|
|
|
|||
|
|
### Deprecated
|
|||
|
|
|
|||
|
|
* `fcft_size_adjust()`
|
|||
|
|
|
|||
|
|
|
|||
|
|
## 2.1.3
|
|||
|
|
|
|||
|
|
### Fixed
|
|||
|
|
|
|||
|
|
* Advance width and height of scaled bitmap fonts.
|
|||
|
|
|
|||
|
|
|
|||
|
|
## 2.1.2
|
|||
|
|
|
|||
|
|
### Changed
|
|||
|
|
|
|||
|
|
* Glyph cache now resizes dynamically. This fixes a performance
|
|||
|
|
problem when loading **a lot** of glyphs, as we ended up scanning
|
|||
|
|
very long lists when looking up a glyph in the cache.
|
|||
|
|
|
|||
|
|
|
|||
|
|
## 2.1.1
|
|||
|
|
|
|||
|
|
### Changed
|
|||
|
|
|
|||
|
|
* Prefer user-provided `charset`. This can be used to e.g. limit a
|
|||
|
|
fallback font's usage to a custom Unicode point range.
|
|||
|
|
|
|||
|
|
|
|||
|
|
### Fixed
|
|||
|
|
|
|||
|
|
* LCD RGB/BGR modes were reversed.
|
|||
|
|
|
|||
|
|
|
|||
|
|
## 2.1.0
|
|||
|
|
|
|||
|
|
### Added
|
|||
|
|
|
|||
|
|
* When looking for a glyph in the fallback fonts, don't discard
|
|||
|
|
(destroy/unload) the fonts that did not contain the glyph. This
|
|||
|
|
improves performance massively when loading lots of glyphs that does
|
|||
|
|
not exist in the primary font, or in the first fallback font(s).
|
|||
|
|
* Synthetic bold and italics (FontConfig's _embolden_ and _matrix_
|
|||
|
|
properties).
|
|||
|
|
* `fcft_precompose()` - combines a base- and a combining wide
|
|||
|
|
character into a single pre-composed character.
|
|||
|
|
|
|||
|
|
|
|||
|
|
### Changed
|
|||
|
|
|
|||
|
|
* `fcft_from_name()` and `fcft_size_adjust()` no longer calls
|
|||
|
|
`setlocale()` to set a suitable locale for `FcParseName()`, as this
|
|||
|
|
was not thread safe. The caller is responsible for ensuring
|
|||
|
|
`LC_NUMERICAL` is set to a locale that correctly recognizes _x.y_
|
|||
|
|
decimal values.
|
|||
|
|
|
|||
|
|
|
|||
|
|
### Fixed
|
|||
|
|
|
|||
|
|
* `fcft_from_name()` was not thread safe
|
|||
|
|
* `fcft_clone()` was not thread safe
|
|||
|
|
* `fcft_size_adjust()` was not thread safe
|
|||
|
|
* `fcft_destroy` was not thread safe
|
|||
|
|
|
|||
|
|
|
|||
|
|
## 2.0.0
|
|||
|
|
|
|||
|
|
### Changed
|
|||
|
|
|
|||
|
|
* API: `font_` prefix changed to `fcft_`.
|
|||
|
|
* API: renamed `struct font` to `struct fcft_font`.
|
|||
|
|
* API: renamed `struct glyph` to `struct fcft_glyph`.
|
|||
|
|
* API: internal members of `struct fcft_glyph` removed.
|
|||
|
|
* API: renamed `enum subpixel_order` to `enum fcft_subpixel`, and
|
|||
|
|
`ORDER` was removed from the enum values.
|
|||
|
|
* API: renamed `fcft_glyph.x_advance` to `fcft_glyph.advance.x`, and
|
|||
|
|
added `fcft_glyph.advance.y`
|
|||
|
|
* API: renamed `fcft_font.max_x_advance` to `fcft_font.max_advance.x`
|
|||
|
|
and added `fcft_font.max_advance.y`.
|
|||
|
|
* API: renamed `fcft_font.space_x_advance` to
|
|||
|
|
`fcft_font.space_advance.x` and added `fcft_font.space_advance.y`.
|
|||
|
|
* API: renamed `fcft_glyph_for_wc()` to `fcft_glyph_rasterize()`.
|
|||
|
|
* Require meson >= 0.54.
|
|||
|
|
* Use `meson.override_dependency()`.
|
|||
|
|
|
|||
|
|
|
|||
|
|
### Fixed
|
|||
|
|
|
|||
|
|
* `fcft_kerning()` did not scale the returned kerning distances with
|
|||
|
|
the font's pixel size fixup multiplier.
|
|||
|
|
|
|||
|
|
|
|||
|
|
## 1.1.7
|
|||
|
|
|
|||
|
|
### Fixed
|
|||
|
|
|
|||
|
|
* LCD RGB/BGR modes were reversed
|
