NAME

       unibmp2hex - Bitmap graphics file to GNU Unifont .hex file converter

SYNOPSIS

       unibmp2hex [-phexpage] [-iinput_file] [-ooutput_file] [-w]

DESCRIPTION

       unibmp2hex  reads  a  bitmap  produced  by  unihex2bmp  before or after
       editing, and converts it back into a Unifont  .hex  format  file.   The
       graphics file contains a block of 256 Unicode code points arranged in a
       16 by 16 grid.  Each code point appears in  a  32  by  32  pixel  grid.
       Characters are either 16 rows by 8 columns, or 16 rows by 16 columns.

OPTIONS

       -ppagenum   Specify  that  the  code points will be assigned to the 256
                   block space pagenum in the .hex file.   If  not  specified,
                   unibmp2hex  will determine the appropriate block by reading
                   the row and column headers.  Note  that  "page"  is  not  a
                   standard  Unicode  term.   It  refers  to  an output bitmap
                   graphics page of 16 by  16  code  points.   If  pagenum  is
                   greater  than FF, the block resides above the Unicode Basic
                   Multilingual Plane. In  that  event,  the  .hex  file  will
                   contain eight digit hexadecimal code points rather than the
                   Unifont standard of four hexadecimal code points.

       -i          Specify the input file. The default is stdin.

       -o          Specify the output file. The default is stdout.

       -w          Force all output .hex glyphs to be 16  pixels  wide  rather
                   than dual width (8 or 16 pixels).

       Sample usage:

       unibmp2hex -imy_input_file.bmp -omy_output_file.hex

FILES

       *.bmp or *.wbmp graphics files

BUGS

       No  known  real  bugs exist, except that this software does not perform
       extensive error checking on its input files.  If  they’re  not  in  the
       format  of  the original bitmapped output from unihex2bmp, all bets are
       off.

       If the output file is for a "page" containing space code points and the
       bitmap  file  squares  for  those code points are not empty, unibmp2hex
       preserve the graphics as they are drawn.  They will  be  removed  later
       using   uniunmask,   with  spaces  of  the  appropriate  width  from  a
       substitutes.hex file.
