[Gimp-user] warp by points

2010-12-27 Thread rich
What I'd like to be able to do is something like georeferencing images 
in a GIS.  That is, having a base image I refer to, create a series of 
points on the base and another image of a different scale that 
correspond to the same places, and the new image will be adjusted to 
match.  Is there a way to do this with GIMP?  I have not been able to 
find anything like this so far in looking around.  Maybe I just don't 
know the correct terminology for GIMP.

Thanks for your help-
Peter

Not really any suggestions for gimp but it is cold and boring here in the UK so 
I ran out a small video using Art of Illusion.  
How it would perform with your presumably large images I do not know. Anyway 
FWIW and only 4 mins long

This plug-in aligns two layers based on two points in each layer:

It's been some time since I messed with it - IIRC you may need to
tweak the register line of the script before it will appear in the
menu.  There was some discussion here:

Have you looked at Hugin? I know it is used for similar things:

and a more generic tutorial for hugin:
