I can't assure you this for all the pictures (as they come from different
sources), but yes, most of them use the same exact grid.
On the other hand, if it makes a difference, the picture boundary (the
zeroes in the examples I sent) can be omitted.

Actually not that many (ranging from 20 to 40 in a monthly-basis) - mainly
because the conversion has to be done by hand. However, pictures would grow
really fast if a Perl script, for instance, makes the hard part.

Hmmm, I looked at this problem mainly for learning purposes - I thought on
Perl because hard things seems to be easier with Perl. Just I wasn't aware
that this issue could be _that_ hard.
