I'm using exactly the same transformation routines as panotools. I've
written my own remapping function with that information, since the pano
tools version was a bit to slow. (the preview also uses bilinear
interpolation now, before it just did nearest neighbour, for speed).

I'm just not sure why it doesn't work for the images near the poles get
cropped before they reach pitch=90.

Hmm, I haven't implemented a method to get the size of a remapped image
pixel, just for the center of the pixel. so the region of interest (ROI)
for the remapping might be a few pixels to small at the poles. hmm.

Jep, thats possible and how the preview window works. (actually it still
uses full screen images, but only remap the ROI.) putting this
into PTStitcher is probably impossible, so it would require a completely new
stitcher.

That would be a nice thing to have. But it should also be possible to do
this just with the multiple tiff output of pano tools:

for(all pics) {
   calculate ROI that contains all non black pixels
   add cropped layer to output tiff
}
save output tiff.

Then gimp/cinepaint needs to be able to read these multilayer tiff. since
I'm not familar with the tiff libraries, I haven't started writing it
myself. 

speaking of gimp. Is there a plugin that can calculate curves,
based on two similar regions, like its done by PTStitcher?

ciao
