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 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 idx Start with glyph index idx (default is 0, which means to process all glyphs).
-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 n Set render mode to n:
0 normal
1 light
2 mono
3 horizontal LCD
4 vertical 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 glyphs (FT_Load_Glyph)
b load advance widths (FT_Get_Advances)
c render glyphs (FT_Render_Glyph)
d load glyphs (FT_Get_Glyph)
e get glyph cboxes (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 or FT_New_Memory_Face)
i embolden glyphs (FT_GlyphSlot_Embolden)
j get glyph bboxes (FT_Outline_Get_BBox)
(default is abcdefghij, this is, all tests).
The number of used glyphs per test (within a single iteration) is given by option -i.
-v Show version.
