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.
