ddbugtopbm - convert Diddle or DiddleBug sketches to PBM files
This program is part of Netpbm(1).
ddbugtopbm converts all sketches present in a database used by the Pal-
mOS programs Diddle or DiddleBug into appropriately-named PBM files.
The backup copy of DiddleBug’s database you should use as this pro-
gram’s input is usually called DiddleBugDB.pdb. Or if you use the
original Diddle, it has two separate DBs - DiddleDB.pdb, containing
unnamed ‘scratch’ sketches, and DiddleIDB.pdb, containing the saved
(and named) sketches which are listed by its ‘index’ option. You can
feed this program any of these three on standard input.
USING THE PROGRAM
I recommend you not run ddbugtopbm from your Palm backup directory,
i.e. don’t run it from the directory the DB will normally be in.
Instead, run it from some other directory (perhaps you could make a
directory purely to hold the PBM files, just to keep things simple) and
use an absolute or relative path to the DB.
The filenames used for the output PBMs are based on the names given to
each sketch; if you have an unnamed sketch, it’s given a name along the
lines of sketch-0123.pbm.
While the named sketches will overwrite any existing PBM file with the
same name, the unnamed ones won’t - they’ll just try using another
filename. (I think this is probably the right approach, as you can’t
really tell the unnamed sketches apart.)
The DiddleBug DB reader is only known to work with DBs from DiddleBug
version 2.50. But it should probably work on later versions, and I
think it’ll work on DBs from version 2.15 as well.
It might fall over if fed an empty database, and doesn’t do much (if
any) checking of the input.

Mitch Blevins’s decompression code is directly from DiddleBug itself,
which like ddbugtopbm is distributed under the terms of the GNU GPL.
Jens-Chr. Heyer’s ‘didcon’ script does something similar.
ddbugtopbm was new in Netpbm 10.18 (August 2003). It was written and
independently distributed in August 2002.
