1ftrandom 2-------- 3 4This program expects a set of directories containing good fonts, and a set 5of extensions of fonts to be tested. It will randomly pick a font, copy it, 6introduce and error and then test it. 7 8The FreeType tests are quite basic: 9 10 For each erroneous font it 11 forks off a new tester; 12 initializes the library; 13 opens each font in the file; 14 loads each glyph; 15 (optionally reviewing the contours of the glyph) 16 (optionally rasterizing) 17 closes the face. 18 19If the tester exits with a signal, or takes longer than 20 seconds then 20ftrandom saves the erroneous font and continues. If the tester exits 21normally or with an error, then the superstructure removes the test font and 22continues. 23 24Arguments are: 25 26 --all Test every font in the directory(ies) no matter 27 what its extension (some CID-keyed fonts have no 28 extension). 29 --check-outlines Call FT_Outline_Decompose on each glyph. 30 --dir <dir> Append <dir> to the list of directories to search 31 for good fonts. 32 --error-count <cnt> Introduce <cnt> single-byte errors into the 33 erroneous fonts. 34 --error-fraction <frac> Multiply the file size of the font by <frac> and 35 introduce that many errors into the erroneous 36 font file. 37 --ext <ext> Add <ext> to the set of font types tested. Known 38 extensions are `ttf', `otf', `ttc', `cid', `pfb', 39 `pfa', `bdf', `pcf', `pfr', `fon', `otb', and 40 `cff'. 41 --help Print out this list of options. 42 --nohints Specify FT_LOAD_NO_HINTING when loading glyphs. 43 --rasterize Call FT_Render_Glyph as well as loading it. 44 --result <dir> This is the directory in which test files are 45 placed. 46 --test <file> Run a single test on a pre-generated testcase. 47 Done in the current process so it can be debugged 48 more easily.
