[gdal-dev] Transform from ground control points

[Livneh Yehiyam]

Hi
I have an image with 4 control points at the 4 corners. From my understanding, this defines a perspective linear transform (not necesserally affine).
I'm trying to warp it into an orthophoto.
from what I see in the gdalgcptransform code it seems that only an affine transform is created. Is it the correct way of doing this projection, or is gdalgcptransform not the correct way of doing it?
thanks
