FreeType is a portable and efficient library for rendering fonts. It
|
|
supports TrueType, Type 1, CFF fonts, and WOFF, PCF, FNT, BDF and PFR
|
|
fonts. It has a bytecode interpreter and has an automatic hinter called
|
|
autofit which can be used instead of hinting instructions included in
|
|
fonts.
