NAME
ddbugtopbm - convert Diddle or DiddleBug sketches to PBM files
SYNOPSIS
ddbugtopbm
EXAMPLES
ddbugtopbm </path/to/palm/backup/dir/DiddleBugDB.pdb
ddbugtopbm </path/to/palm/backup/dir/DiddleDB.pdb
ddbugtopbm </path/to/palm/backup/dir/DiddleIDB.pdb
DESCRIPTION
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 program'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 pro-
gram any of these three on standard input.
OPTIONS
There are no command line options defined specifically for ddbugtopbm,
but it recognizes the options common to all programs based on libnetpbm
(See ]8;;index.html#commonoptions\ Common Options]8;;\ .)
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 ab-
solute 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 file-
name. (I think this is probably the right approach, as you can't really
tell the unnamed sketches apart.)
LIMITATIONS
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.
