FreeType Fixes Inefficient Code Causing 10x Startup Time Hit When Loading Arial TTF Font
The FreeType library for rendering text onto bitmaps that is widely used by a variety of applications has landed a set of three patches today providing an important performance improvement to address a significant inefficiency within the existing FreeType codebase.
Open-source developer Werner Lemberg has landed a set of three patches for speeding up the creation of the adjustment database's reverse map. Werner Lemberg explained in the first patch of the series now merged to FreeType Git:"As it turns out, the original implementation using `hb_ot_shape_glyphs_closure` is extremely slow if a font has a rich set of OpenType features.
