I recently got a new Treo 600 Phone/PDA/Camera and found there was no good software to extract the pictures from the phone. After doing some research on the format of the files, I put together the following. Just edit the $syncdir variable at the top to point to where your files are.
#!/usr/bin/perl -w
use strict;
use Palm::PDB;
use Palm::Raw;
# Set this to the dir the ImageLib_imageDB.pdb
# and ImageLib_mainDB.pdb files are in
my $syncdir = ".";
my %imagedata;
my $imagedb = new Palm::PDB;
my $maindb = new Palm::PDB;
$imagedb->Load("$syncdir/ImageLib_imageDB.pdb");
$maindb->Load("$syncdir/ImageLib_mainDB.pdb");
# Gather picture data, indexed by Record ID. The phone has only 32Meg
+s
# of memory, so it shouldn't be restrictive to load all the data into
# memory
foreach my $record (@{$imagedb->{records}}) {
$imagedata{$record->{id}} = $record->{data};
}
# Records in the mainDB give the filename, and record number
# of the start of each picture
foreach my $record (@{$maindb->{records}}) {
my ($file, $startpic, $startthumb, $nbrecpic, $nbrecthumb)
= unpack "A32x8Lx4LSS", $record->{data};
print "$file.jpg";
open JPG, ">", "$file.jpg" or die "Couldn't open $file.jpg: $!\n";
my $nextrec = $startpic;
# Write data to image file, following the Next Record pointers
# until the last one is found
while ($nextrec != 0) {
my ($next, $data) = unpack "La*", $imagedata{$nextrec};
print JPG $data;
print ".";
$nextrec = $next;
}
print "\n";
close JPG;
}
