General fixes: |
|
============= |
|
|
|
- Instead of forming clusters immediately, only do it if we are reversing |
|
the text. We'd need a separate bit to indicate cluster start then. |
|
|
|
- Right now, BTW, for non-native direction runs, we get the cluster wrong... |
|
Should do min(input-glyphs.cluster) |
|
|
|
- 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 |
|
|
|
|
|
API issues to fix before 1.0: |
|
============================ |
|
|
|
- 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) |
|
|
|
- hb_shape() currently does a bit more than hb_ot_shape(). Shouldn't. |
|
|
|
- Add glib GBoxedType stuff and introspection |
|
|
|
|
|
API to add (maybe after 1.0): |
|
============================ |
|
|
|
- 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) |
|
|
|
- Full matrix instead of scale? |
|
|
|
- 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 |
|
|
|
|
|
Optimizations: |
|
============= |
|
|
|
- Avoid allocating blob objects internally for for_data() faces? |
|
|
|
- Add caching layer to hb-ft
