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.
