It will randomly pick a font, copy it, +introduce and error and then test it. + +The FreeType tests are quite basic: + + For each erroneous font it + forks off a new tester; + initializes the library; + opens each font in the file; + loads each glyph; + (optionally reviewing the contours of the glyph) + (optionally rasterizing) + closes the face. + +If the tester exits with a signal, or takes longer than 20 seconds then +ftrandom saves the erroneous font and continues. If the tester exits +normally or with an error, then the superstructure removes the test font and +continues. + +Arguments are: + + --all Test every font in the directory(ies) no matter + what its extension (some CID-keyed fonts have no + extension). + --check-outlines Call FT_Outline_Decompose on each glyph. + --dir <dir> Append <dir> to the list of directories to search + for good fonts. + --error-count <cnt> Introduce <cnt> single-byte errors into the + erroneous fonts. + --error-fraction <frac> Multiply the file size of the font by <frac> and + introduce that many errors into the erroneous + font file. + --ext <ext> Add <ext> to the set of font types tested. Known + extensions are `ttf', `otf', `ttc', `cid', `pfb', + `pfa', `bdf', `pcf', `pfr', `fon', `otb', and + `cff'. + --help Print out this list of options. + --nohints Specify FT_LOAD_NO_HINTING when loading glyphs. + --rasterize Call FT_Render_Glyph as well as loading it. + --result <dir> This is the directory in which test files are + placed. + --test <file> Run a single test on a pre-generated testcase. + Done in the current process so it can be debugged + more easily. |
