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:

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 indices (FT_Get_Char_Index)
f	iterate CMap (FT_Get_{First,Next}_Char)
g	open a new face (FT_New_Face or FT_New_Memory_Face)
h	embolden glyphs (FT_GlyphSlot_Embolden)
i	stroke glyphs (FT_Glyph_Stroke)
j	get glyph bboxes (FT_Outline_Get_BBox)
k	get glyph cboxes (FT_Glyph_Get_CBox)
l	open a new face and load glyphs

(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:

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).

-v

Show version.
