ftgrid - simple glyph grid viewer

ftgrid displays the glyphs of a font as outlines right before the conversion from outlines to pixels take
       place.   It  also  displays  the  resulting  bitmap.   It is possible to interactively change hinting and
       rendering options, thus visualizing the applied distortions to the outlines.

       pt     The point size for the given resolution.  If resolution is 72dpi, this  directly  gives  the  ppem
              value (pixels per EM).

       font   The font file(s) to display.  For Type 1 font files, ftgrid also tries to attach the corresponding
              metrics file (with extension `.afm' or `.pfm').

       This program is part of the FreeType demos package.

-dWxH[xD]
              Set  the  window  width  to  W px, the height to H px, and optionally the depth to D bpp (default:
              640x480x24).

       -rr   Use resolution r dpi (default: 72dpi).

       -findex
              Specify first index to display (default: 0).

       -eenc Specify encoding tag (default: no encoding).  Common values: unic (Unicode), symb  (symbol),  ADOB
              (Adobe standard), ADBC (Adobe custom), or a numeric charmap index.

       -a"axis1axis2..."
              For  Multiple Master, GX, or OpenType variation fonts, specify design coordinates for each axis at
              start-up.  This option implies option -n.  Ignored for all other font formats.

       -n     Don't display named instances of variation fonts.

       -kkeys
              Emulate sequence of keystrokes upon start-up.  If the keystrokes contain 'q', the program operates
              in batch mode.  Function keys Fx are mapped to character codes 0xFx; as an example, -k$'\xF3q' is
              function key 'F3' followed by character 'q'.

       -v     Show version.
