Bitmap-data helper modules
Overview:
The modules documented on this page are helpers for
fontTools.ttLib that implement lower-level support for various
table converters that need to interact with bitmapped data. The
BitmapGlyphMetrics module is used for the EBDT/EBLC and
CBDT/CBLC tables, and sbixGlyph and sbixStrike
are used for the sbix table.
