Using the photo as a background, I need to scale and rotate the map image so that the two line up. Is this possible with the Gimp? What approach should I use? If it's not feasable with Gimp, does anyone know any (Linux) software which would be suitable? Definitely possible and feasable. As long as you have a simple perspective transform in your images. Once things like WGS'84 and other coordinate systems rear their head, the best bet is something made for this like GRASS. Anyway, the main tool you would be looking for is the Rotate, Scale, Shear, and Perspective tools (Shift-R, Shift-T, Shift-S, Shift-P by default) Perspective and Rotate will probably be the most useful. I've done it, and it works as long as your data isn't too distorted. Don't try anything like the overlays Google Maps does, though, you would definitely need something like GRASS then.

[Gimp-user] Anyone good at converting/porting scripts from perl to python?
I have been trying to get Gimp Perl to run without success for a while now.
I have decided to try another way..
The script i want to run is as follows;
#!/usr/bin/perl
use Gimp qw( :auto );
use Gimp::Fu;
registercenter_guide,
Creates h- v-guides at the center of the image.,
Physical center = width/2 and height/2; Optical center = the
Golden Mean.,

$h = $img-height();
$hc = int($h/2 + 0.5);
$vc = int($w/2 + 0.5);
if ($center == 1) {
$hc = int(($h / 2.6179) + 0.5);

$bit_bucket = $img-add_hguide($hc);
$bit_bucket = $img-add_vguide($vc);
gimp_drawable_update($layer, 0, 0, $w, $h);
};
exit main;
How do i convert it to python?
Python i DO have working...

I do not know much perl, but it is quite straightforward.
I suppose you know that in python identation does matter, and is used
to separate blocks, instead of {} or begin end.
That said, the script bellow becomes:
(I will let the perl lines commented on the script. you may erase then
later)
#!/usr/bin/python
