unifontpic reads a GNU Unifont .hex file from STDIN and writes a two dimensional rendering for each glyph
       to  STDOUT.   The  output  displays  an entire Unicode plane of 65,536 glyphs as one large graphic image,
       showing a grid of 256 glyphs by 256 glyphs as the default, or (at your  option)  a  long  version  of  16
       glyphs across by 4,096 glyphs down.

       Input  can be one or more files in Unifont .hex format.  They don't have to be sorted, as unifontpic will
       populate the entire glyph array of 65,536 code points before writing its output.  The  input  glyph  code
       points should all be unique, as feeding in duplicate code points will produce unpredictable results.  Use
       unidup(1) on a sorted input of .hex files to guarantee no code point duplication.

       Sample usage:

              cat *.hex | unifontpic -d120 > unifontpic.bmp

       To generate a bitmap that shows combining circles, from the font/ subdirectory:

              sort plane00/*.hex | unigencircles ttfsrc/combining.txt | unifontpic -d120 >unifontpic.bmp

-d    Specify  a  Dots  per  Inch (DPI) resolution of nnn.  For example, specifying -d120 will encode the
             bitmap graphics file output as having a resolution of 120 DPI.

       -l    Produce a long chart, 16 glyphs wide by 4,096 glyphs tall.  The default is a wide chart, 256 glyphs
             wide by 256 glyphs tall.

       -t    Use tiny numbers for the row and column code point labels.  Tiny numbers are on  a  4  by  5  pixel
             grid.   Only  tiny  code point labels appear on the long chart variant; this option only has effect
             for wide charts (the default, of 256 by 256 glyphs).  If this  option  is  not  specified  for  the
             default  256-by-256  grid, row and column code point labels are taken from Unifont's glyphs for `0'
             to `9' and `A' to `F'.

       -P    Print a chart for  Unicode  plane  number  plane.   The  default  is  Plane 0,  the  Unicode  Basic
             Multilingual  Plane (BMP).  The range of Unicode plane range is 0 through 17, inclusive.  The plane
             number is printed on the chart title line.
