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 patterns 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.
OPTIONS
-d WxH[xD]
Set the window width to W px, the height to H px, and optionally the depth to D bpp (default:
640x480x24).
-r r Use resolution r dpi (default: 72dpi).
-e enc Specify encoding tag (default: no encoding). Common values: unic (Unicode), symb (symbol), ADOB
(Adobe standard), ADBC (Adobe custom), or a numeric charmap index.
-m text
Use text for rendering.
-k keys
Emulate sequence of keystrokes upon start-up. If the keystrokes contain 'q', the program operates
in batch mode. Function keys Fx are mapped to character codes 0xFx; as an example, -k $'\xF3q' is
function key 'F3' followed by character 'q'.
-v Show version.
