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.
