NAME¶
ftbench - benchmark some common FreeType paths
SYNOPSIS¶
ftbench [options] fontname
DESCRIPTION¶
The ftbench tool measures performance of some common FreeType operations.
This program is part of the FreeType demos package.
OPTIONS¶
- -C
- Compare with cached version if available.
- -c n
- Use at most n iterations for each test (0 means time limited).
- -f l
- Use hexadecimal (not decimal) number l as load flags (see
the `FT_LOAD_XXX' macros in the FreeType reference).
- -H
- Use alternative hinting engine (Adobe CFF or TTF v35).
- -i idx
- Start with index idx (default is 0).
- -m m
- Set maximum cache size to M KiByte (default is 1024).
- -p
- Preload font file in memory.
- -r n
- Set render mode to n:
0 |
normal |
1 |
light |
2 |
mono |
3 |
horizontal LCD |
4 |
verical LCD |
- (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).
- -b tests
- Perform chosen tests:
a |
load a glyph (FT_Load_Glyph) |
b |
load advance widths (FT_Get_Advances) |
c |
render a glyph (FT_Render_Glyph) |
d |
load a glyph (FT_Get_Glyph) |
e |
get glyph cbox (FT_Glyph_Get_CBox) |
f |
get glyph indices (FT_Get_Char_Index) |
g |
iterate CMap (FT_Get_{First,Next}_Char) |
h |
open a new face (FT_New_Face) |
i |
embolden (FT_GlyphSlot_Embolden) |
j |
get glyph bbox (FT_Outline_Get_BBox) |
- (default is abcdefghij, this is, all tests).
- -v
- Show version.
