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

-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.
