General fixes:
|
|
=============
|
|
|
|
- Move feature parsing from util into the library
|
|
|
|
- 'const' for getter APIs? (use mutable internally)
|
|
|
|
- Fix TT 'kern' on/off and GPOS interaction (move kerning before GPOS)
|
|
|
|
- Do proper rounding when scaling from font space?
|
|
|
|
- Misc features:
|
|
* init/medi/fina/isol for non-cursive scripts
|
|
* vkna,hkna etc for kana, *jmo for hangul, etc
|
|
|
|
- Move non-native direction and normalization handling to the generic non-OT
|
|
layer, such that uniscribe and other backends can use.
|
|
|
|
- Uniscribe backend needs to enforce one direction only, otherwise cluster
|
|
values can confused the user.
|
|
|
|
|
|
API issues to fix before 1.0:
|
|
============================
|
|
|
|
- Rename all internal symbols (static ones even) to have _hb prefix?
|
|
|
|
- Add pkg-config files for glue codes (harfbuzz-glib, etc)
|
|
|
|
- Figure out how many .so objects, how to link, etc
|
|
|
|
- Add hb-cairo glue
|
|
|
|
- Add sanitize API (and a cached version, that saves result on blob user-data)
|
|
|
|
- Add glib GBoxedType stuff and introspection
|
|
|
|
|
|
API to add (maybe after 1.0):
|
|
============================
|
|
|
|
- Add Uniscribe face / font get API
|
|
|
|
- BCP 47 language handling / API (language_matches?)
|
|
|
|
- Add hb_face_get_glyph_count()?
|
|
|
|
- Add hb_font_create_linear()?
|
|
|
|
- Add hb_shape_plan()/hb_shape_execute()
|
|
|
|
- Add query API for aalt-like features?
|
|
|
|
- SFNT api? get_num_faces? get_table_tags? (there's something in stash)
|
|
|
|
- Add segmentation API
|
|
|
|
- Add hb-fribidi?
|
|
|
|
|
|
hb-view enhancements:
|
|
====================
|
|
|
|
- Add --format
|
|
- Add --width, --height, --auto-size, --align, etc?
|
|
- Port to GOption, --help
|
|
- Add XML and JSON formats
|
|
|
|
|
|
Tests to write:
|
|
==============
|
|
|
|
- ot-layout enumeration API (needs font)
|
|
|
|
- Finish test-shape.c, grep for TODO
|
|
|
|
- Finish test-unicode.c, grep for TODO
|
|
|
|
|
|
Optimizations:
|
|
=============
|
|

|
|
|
|
- Add caching layer to hb-ft
