DESCRIPTION

12       ftlint  opens  the given font(s), loads and renders glyphs at the given
13       ppem value.  For successfully rendered glyphs, it calculates the bitmap
14       MD5 checksum for regression testing as well as horizonal (X) and verti‐
15       cal (Y) acutances for quality assessment.  The acutance is equal to 2.0
16       for  monochrome bitmap fonts and approaches this value for hinted anti-
17       aliased fonts.
