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).
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.
