Hi Mathew,
thanks for your reply. I think it does not work for this kind of large size project, because all the image has to be warped/morphed throughout the whole image area, and the triangular mesh would not be accurate enough (there seems to be a low limit to the amount of triangulars). I noticed it would be very practical, as you say, for fine tuning an image – but morphing drastically a whole image seems not working accurate enough. (Also, there would not be any automatic detection in the mesh pattern.)
If you or any others would have any other solutions, please let me know.
Thanks!
