NAME
       ftlint - simple font tester


SYNOPSIS
       ftlint [options] ppem font...


DESCRIPTION
       ftlint  opens  the  given  font(s), loads and renders glyphs at the given ppem value.  The
       shape complexity of outline glyphs are examined based on  their  taxicab  perimeters:  the
       higher  the  number,  the  more  complex  the shape.  For successfully rendered glyphs, it
       calculates the bitmap MD5 checksum for regression testing as well as  horizontal  (X)  and
       vertical  (Y)  acutances  for  quality  assessment.   The  acutance  is  equal  to 2.0 for
       monochrome bitmap fonts and approaches this value for hinted anti-aliased fonts.

       ppem   Size in pixels per EM.

       font   The font file(s) to test.

       This program is part of the FreeType demos package.


OPTIONS
       -f L   Use hexadecimal (not decimal) number L defined by FT_LOAD_XXX flags (default is 0).

       -r N   Set render mode to N:

              0   normal
              1   light
              2   mono
              3   horizontal LCD
              4   vertical LCD

              which corresponds to the values of the FT_RENDER_MODE_XXX enumeration  (default  is
              0).

       -i I-J Range of glyph indices to use (default: all).

       -q     Quiet mode without the rendering analysis.
