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 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.)





BUGS

       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.
