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

       -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 idx Start with glyph index idx (default is 0, which means to process all glyphs).

       -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).

       -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 cboxes (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 or FT_New_Memory_Face)
              i   embolden glyphs (FT_GlyphSlot_Embolden)

              j   get glyph bboxes (FT_Outline_Get_BBox)

              (default is abcdefghij, this is, all tests).

              The  number  of used glyphs per test (within a single iteration) is given by option
              -i.

       -v     Show version.
