Instead of opening the same font multiple times for each different
size (multiple face instances), share one face instance and create
multiple size instances.
Add a submenu allowing users to add Noto Sans fonts
to be used as UI fallback fonts.
Lots of them are alrady there on Android, but can be
downloaded (manually) and side-loaded by the user
on other platforms.
A few fixes and enhancement related to bold text:
- When using bold=true with a regular font, use its bold
variant if one exists (can be prevented by manually
adding a setting: "use_bold_font_for_bold" = false).
- When using a bold font without bold=true, promote bold
to true, so fallback fonts are drawn bold too.
- Whether using a bold font, or using bold=true, ensure
fallback fonts are drawn bold, with their available bold
variant if one exists, or with synthetized bold.
- When using a bold variant of a fallback font, keep using
the regular variant as another fallback (as bold fonts
may contain less glyphs than their regular counterpart).
- Allow providing bold=Font.FORCE_SYNTHETIZED_BOLD to
get synth bold even when a bold font exists (might be
interesting to get text in bold the same width as the
same text non-bold).
- Use the font realname in the key when caching glyphs,
instead of our aliases (cfont, infont...) to avoid
duplication and wasting memory.
bump base for libkoreader-xtext.so:
- ffi/pic.lua: fix memory leak with some unsupported PNG files
- FreeType ffi: add methods for use with Harfbuzz shaping
- thirdparty: adds libunibreak
- Adds libkoreader-xtext.so: enhanced text shaping
Add a getFallbackFont(N) to each Lua font object to instantiate
(if not yet done) and return the Nth fallback font for the font.
Fallback fonts list: add NotoSansArabicUI-Regular.ttf
Add RenderText:getGlyphByIndex() to get a glyph bitmap by glyph
index, which is what we'll get from Harfbuzz shaping.
(RenderText:getGlyph() works with unicode charcode).
* Unify battery meters look'n feel
Switch to proper (vertical) battery icons (one per 10% steps).
Fix#5535
* Bump fonts (https://github.com/koreader/koreader-fonts/pull/7)
Because we need the new symbols from nerdfonts ;).
When no height= provided, and the InfoMessage would overflow
screen height when some long message is provided, decrease the
font size until the widget fit.
* Discard dotfiles when looking for fonts
So as not to pickup, among other things:
* macOS resource forks
* *nix hidden files (which may be stale fuse ghosts on Kindle)
* Update Kindle font blacklist
Up to FW 5.9.6
Basically blacklist anything non-LGC, requiring lab126's FT build, or FC tweaks.
One day we'll fix CRe instead, maybe.
* Minor cleanup
We don't ship Droid Sans Fallback anymore
* Tweak UI fallback font list for better coverage
* Bump base & fonts
To pickup related changes
It turns out that one of our mupdf patch reads the FONTDIR env var
and uses it in a totally different way so we will use another env var
EXT_FONT_DIR to define external font directory for different platforms.
to support custom font directory for EPUB documents
Now Koreader could find fonts in the "fonts" directory in the USB root
directory of kindle, Kobo and PocketBook devices, thus no need to copy
fonts to "koreader/fonts" directory.
This is a major overhaul of the hardware abstraction layer.
A few notes:
General platform distinction happens in
frontend/device.lua
which will delegate everything else to
frontend/device/<platform_name>/device.lua
which should extend
frontend/device/generic/device.lua
Screen handling is implemented in
frontend/device/screen.lua
which includes the *functionality* to support device specifics.
Actually setting up the device specific functionality, however,
is done in the device specific setup code in the relevant
device.lua file.
The same goes for input handling.
