NAME

       unihex2png - GNU Unifont .hex file to Portable Network Graphics converter

SYNOPSIS

       unihex2png [-i input_file.hex ] -o output_file.png [-p pagenum ] [-r rows ]

DESCRIPTION

       unihex2png  reads  a  page  of  256  Unicode  code points from a GNU Unifont .hex file and
       converts the page into a Portable Network Graphics (PNG) file.  The graphics file displays
       the  glyphs  of a Unicode block of 256 code points in a 32 by 32 pixel grid, or in a 40 by
       40 pixel grid if "-r 32" is specified.  The glyphs themselves can be either 16, 24, or  32
       pixels  tall  depending  on  the "-r" parameter.  They can be 8, 16, 24, or 32 pixels wide
       (widths of 32 are only supported if "-r 32" is specified).  The default page  is  0;  that
       is, the range U+0000 through U+00FF, inclusive.

       The PNG file can be printed.  It can also be edited with a graphics editor.  An edited PNG
       file can then be re-converted into a GNU Unifont .hex file with the unipng2hex command.

OPTIONS

       -i          Specify the input file.  If not omitted, a Unifont  .hex  file  is  read  from
                   STDIN.

       -o          Specify the output file.

       -p pagenum  Extract page pagenum from the .hex file.  The default is Page 0 (Unicode range
                   U+0000 through U+00FF).  Note that "page" is not a standard Unicode term.   It
                   refers to an output bitmap graphics page of 16 by 16 code points.

       -r rows     Specify the rows of pixels in the output glyphs.  Valid values are 16, 24, and
                   32.  The default is 16 pixel rows tall.

       -h          Print a help message of options and exit.

AUTHOR

       unihex2png was written by Andrew Miller, starting by converting Paul Hardy's unihex2bmp  C
       program to Perl.

BUGS

       No  known  real  bugs exist, but the optional pixel rows parameter is not yet supported by
       all other Unifont utilities.  Use of glyphs taller  than  the  default  of  16  pixels  is
       considered   experimental.    Currently   unihex2png,  unipng2hex,  hexdraw,  and  hex2bdf
       tentatively support glyphs that are 16, 24, and 32 pixels tall.

       Also, there is no extensive error checking on input files.  If they're not in  the  format
       of  the  original GNU Unifont .hex file, all bets are off.  Lines can be terminated either
       with line feed, or carriage return plus line feed.
