ftbench − benchmark some common FreeType paths
ftbench [options] fontname
The ftbench tool measures performance of some common FreeType operations.
This program is part of the FreeType demos package.
−a "axis1 axis2 ..."
For Multiple Master, GX, or OpenType variation fonts, specify design coordinates for each axis at start-up. Ignored for all other font formats.
−b tests
Perform chosen tests:
(default is abcdefghijkl, this is, all tests).
The number of used glyphs per test (within a single iteration) is given by option −i.
|
−C |
Compare with cached version if available. | ||
|
−c N |
Use at most N iterations for each test (0 means time limited). | ||
|
−e E |
Use charmap with index E instead of the default unicode. | ||
|
−f L |
Use hexadecimal (not decimal) number L as load flags (see the ‘- FT_LOAD_XXX’ macros in the FreeType reference). |
−H name
Using CFF hinting engine name. Available versions are depending on compilation options of FreeType; call ftbench without an argument to get the actual list.
|
−I ver |
Using TT interpreter version ver. Available versions are depending on compilation options of FreeType; call ftbench without an argument to get the actual list. | ||
|
−i I-J |
Forward or reverse range of glyph indices to use (default is from 0 to the number of glyphs minus one). | ||
|
−m M |
Set maximum cache size to M KiByte (default is 1024). | ||
|
−p |
Preload font file in memory (this is, testing FT_New_Memory_Face instead of FT_New_Face). | ||
|
−r R |
Set render mode to R: |
(default is 0). This corresponds to the values of the ‘FT_ RENDER_MODE_XXX’ flags.
|
−s S |
Use S ppem as face size (default is 10ppem). If set to zero, don’t call FT_Set_Pixel_Sizes. Use value 0 with option ‘-f 1’ or something similar to load the glyphs unscaled, otherwise errors will show up. | ||
|
−t T |
Use at most T seconds per test (default is 2). | ||
|
−v |
Show version. |
