ft2demos (freetype demos and tools)
Set of demo programs and tools for freetype. Can be useful for testing
and debugging problems with fonts (or with freetype itself). Includes
these tools:
ftbench - benchmark some common FreeType paths
ftchkwd - test fixed font width
ftdiff - compare font hinting modes
ftdump - simple font dumper
ftgamma - screen gamma calibration helper
ftgrid - simple glyph grid viewer
ftlint - simple font tester
ftmemchk - simple memory tester (tests FreeType's memory allocator)
ftmulti - multiple masters font viewer
ftpatchk - tests whether patented hinting is necessary
ftstring - string viewer (displays text in specified font)
fttimer - simple performance timer
ftvalid - font layout table validator
ftview - simple glyph viewer
ttdebug - a TrueType bytecode debugger
Most of the commands have man pages. Also most of the commands show
usage info if you run them with --help (or with no arguments).
