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

       -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 options
              -i and -j.

       -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 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 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).

       -v     Show version.
