OK I guess I have to convert them. Hope I can find a batch command. > > > 2) Where can I find documentation on how to stitch my images > > together?

(Coming from that "other" GIS software.) I want to click on a point on the reference image and then click on the same location on the distorted image. Do this 3 or more times (not in a line) and then tell it to transform. Is there some other package/program that will do this? I don't think Gimp works this way. > > Greetings, > Andr?
