pt font
DESCRIPTION
ftview
displays all glyphs of a font, allowing changes of various rendering
and hinting parameters interactively.
- pt
-
The point size for the given resolution.
If resolution is 72dpi, this directly gives the ppem value (pixels per EM).
- font
-
The font file(s) to display.
For Type 1 font files, ftview also tries to attach the corresponding metrics
file (with extension `.afm' or `.pfm').
This program is part of the FreeType demos package.
