NAME

       unifontpic - Convert GNU Unifont .hex input to a bitmap image of the whole font

SYNOPSIS

       unifontpic [-dnnn][-l][-t] < input-font.hex > output-font.bmp

DESCRIPTION

       unifontpic reads a GNU Unifont .hex file from STDIN and writes a two dimensional rendering
       for each glyph to STDOUT.  The output displays the entire Unicode Basic Multilingual Plane
       (BMP)  as  one  large  graphic  image,  showing  a grid of 256 glyphs by 256 glyphs as the
       default, or (at your option) 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.

OPTIONS

       -dnnn       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'.

EXAMPLES

       Sample usage:

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

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

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

FILES

       *.hex GNU Unifont font files
