NAME
ftstring - string viewer
SYNOPSIS
ftstring [options] pt font ...
DESCRIPTION
ftstring displays a text string with the given font, allowing to change various rendering and display
options 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, ftstring also tries to attach the
corresponding metrics file (with extension `.afm' or `.pfm').
Besides the string, ftstring also displays two stress test pattens sensitive to rendering flaws, such as
incorrect gamma settings. Alternative text-carpeting and waterfall views are also available. This
program is part of the FreeType demos package.
