Compact Font Format, Type2 and OpenType

The Compact Font Format (CFont) was developed by Adobe and it is a container for one or more fonts. Although not compressed, it’s a format designed to save space as the name suggests.

Compact Font Format

The bytecode contained in CFonts is either Type1 or Type2, both very similar and supported by the Profiler, although nothing prevents from storing another type of bytecode.

OpenType

The support of this font format also improves the support for OpenType fonts, because these fonts can store glyph outlines in a CFF table, rather than in a glyf table such as TrueType fonts. CFF tables contain Compact Fonts.

In this last screenshot we can see an example of font detection inside of a PDF.
