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.
