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.
