Contents of README:ftrandom ======== This program expects a set of directories containing good fonts, and a set of extensions of fonts to be tested. It will randomly pick a font, copy it, introduce an error and then test it. The FreeType tests are quite basic; for each erroneous font ftrandom . forks off a new tester, . initializes the library, . opens each font in the file, . loads each glyph, . optionally reviews the contours of the glyph, . optionally rasterizes the glyph, and . closes the face. If a tester takes longer than 20 seconds, 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. Command line options -------------------- --all Test every font in the directory(ies) no matter what its extension. --check-outlines Call `FT_Outline_Decompose' on each glyph. --dir <dir> Append <dir> to the list of directories to search for good fonts. No recursive search. --error-count <cnt> Introduce <cnt> single-byte errors into the erroneous fonts (default: 1). --error-fraction <frac> Multiply the file size of the font by <frac> and introduce that many errors into the erroneous font file. <frac> should be in the range [0;1] (default: 0.0). --ext <ext> Add <ext> to the set of font types tested. --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. This is done in the current process so it can be debugged more easily. The default font extensions tested by ftrandom are .ttf .otf .ttc .cid .pfb .pfa .bdf .pcf .pfr .fon .otb .cff The default font directory is controlled by the macro `GOOD_FONTS_DIR' in the source code (and can be thus specified during compilation); its default value is /usr/local/share/fonts The default result directory is `results' (in the current directory). Compilation ----------- Two possible solutions. . Run ftrandom within a debugging tool like `valgrind' to catch various memory issues. . Compile FreeType with sanitizer flags as provided by gcc or clang, for example, then link it with ftrandom. |
