DESCRIPTION
Dpic
reads a doom picture formatted image (default standard input),
converts it to a Plan 9
image(6)
and writes it to standard out.
Todpic
does the opposite transformation.
A color palette is needed for the process;
its location is set to
/mnt/wad/playpal
by default.
This may be overridden with the
-p
command line option.
Both programs also accept an
-f
flag to indicate processing a doom 64x64 flat picture.
When encoding a doom picture,
x and y offsets are set to the input’s top left corner coordinates.
The
-w
flag sets the offsets so as to center the picture when drawn by the doom engine,
which is useful for wall patches.
The
-b
option sets the RGB24 color to signal transparent pixels,
0x00FFFF
by default.
EXAMPLES
Create a patch
WAD
(see
wadfs(4))
replacing a sky texture.
First, create a 256x128 image, mirror it, and convert it for use with
tweak(1).
% png -9t tuttleglenda.png \\
| resample -x 128 -y 128 \\
| crop -r 0 0 256 128 \\
| rotate -l \\
| iconv -c m8 > tuttlesky
Next, use
tweak(1)
to tile the 128x128 picture.
Then, mount an
IWAD
containing the base color palette, convert to a doom picture,
create a patch
WAD,
then launch doom using it.
