|

:attr:`~Font.antialias`\ ing. If you want to use font by its name rather

TTFQuery_ --- Find and Extract Information from TTF Files
|

TTFQuery builds on the `FontTools-TTX`_ package to allow the Python

programmer to accomplish a number of tasks:
|
||||
|
||||
- query the system to find installed fonts
|
||||
|
||||
- retrieve metadata about any TTF font file
|
||||
|
||||
- this includes the glyph outlines (shape) of individual code-points,
|
||||
which allows for rendering the glyphs in 3D (such as is done in
|
||||
OpenGLContext)
|
||||
|
||||
- lookup/find fonts by:
|
||||
|
||||
- abstract family type
|
||||
- proper font name
|
||||
|
||||
- build simple metadata registries for run-time font matching
