       ttfdump - Dumping the contents of a TrueType Font file


       ttfdump [-h] [-t tablename] [-g glyphnumber] [-c collection] [-o dumpfile] [-i] ttfile


       ttfdump dumps the contents of a TrueType font file in ASCII form.  A TrueType font file is
       consist of various tables. Those table are divided into two categories -  Required  Tables
       and Optional Tables. Mulitiple TrueType fonts can be merged to a TrueType Collection.

              fpgm   font program; not implemented yet.

              gasp   grid-fitting and scan conversion procedure (grayscale)

              hdmx   horizontal device metrics

              kern   kerning table

              LTSH   Linear threshold table

              VDMX   Vertical Device Metrics table

              vhea   vertical metrics header

              vmtx   vertical metrics

              Additional OpenType Tables

              GPOS   glyph positioning table

              GSUB   glyph substitution table

       -g glyphnumber
              If this option is specified then dump the glyph with index  glyphnumber,  otherwise

       To dump all information in the TrueType font file times.ttf:
              ttfdump times.ttf

       To dump the required table cmap in the file:
              ttfdump -t cmap times.ttf
