class HexaPDF::Type::FontType3

Parent	HexaPDF::Type::FontSimple

Represents a Type 3 font.

Note: We assume the /FontMatrix is only used for scaling, i.e. of the form [x 0 0 +/-x 0 0]. If it is of a different form, things won’t work correctly. This will be handled once such a case is found.

See: PDF2.0 s9.6.4
