FL.objects.TTH.TTH

class FL.objects.TTH.TTH(g: Glyph | None = None, f: Font | None = None)

Bases: object

TTH - class to represent a TrueType program

__init__(g: Glyph | None = None, f: Font | None = None) → None

TTH(): generic constructor, creates an empty TTH
TTH(Glyph g): creates TTH, assigns ‘g’ as glyph and ‘parent’ of ‘g’ as font
TTH(Glyph g, Font f): creates TTH, assigns ‘g’ as glyph and ‘f’ as font

Parameters:

g (Glyph | None, optional) – _description_. Defaults to None.
f (Font | None, optional) – _description_. Defaults to None.
