Support laying out text using rustbuzz
notgull opened this issue · 5 comments
This crate looks very good, and I wanted to use it in combination with rustbuzz
to lay out text. However, it looks like there is no support for accessing the underlying ttf_parser
font (unless I missed something). I assume that you don't want to make it a public dependency. Therefore, it would be nice if there was some way (with a feature gate or something) to enable a function that would layout text using rustbuzz
.
You can already layout glyphs using this crate however you choose, though layout functionality isn't provided here nor is it intended to be.
I haven't used rustbuzz so I'm not sure what's lacking to integrate with it.
If you want to access the underlying ttf_parser::Face
I would simply use ttf-parser directly.

Yes, however proper shaping usually needs direct access to the underlying fonts.

Rustbuzz needs either the ttf-parser
face or a byte slice of the raw face. ab-glyph
exposes neither of these items from a FontRef
or FontVec
. I think that exposing the byte slice would fix this issue.

ttf_parser::Face

Then I would need to juggle a ttf_parser::Face
and a ab_glyph::Face
, which feels redundant since both are the same structure.
I think that exposing the byte slice would fix this issue.
For FontRef
you can just keep hold of the slice used to construct it. For FontVec
we could perhaps add as_slice
& into_vec
methods.
#73 will enable this, I can publish that at the end of the week. Will that be enough to resolve this issue?
