Can you tell by reading the exif data if the image was cropped or resized?
There was an issue a little while back on the PTGui list that discussed how different Raw converters produced images on different widths.  Will this cause a problem?  Or will this fix this problem.

Sorry don't have time right now to look it up.

Hi all

I've just finished what I hope will be the final revision of the Wiki page http://wiki.panotools.org/Lens_Correction_in_PanoTools

It is now, I hope, a clear statement of how PT computes correction parameters, why those are not portable between image formats, and what needs to be done to make them portable.

Bottom line, I think: 

This reduces the job of front ends to the bare minimum, of acquiring and posting sensor specs.  It requires no new behavior when the source format has not changed -- that covers all presently valid use cases.  And eliminates the rotated source problem (provided the camera has square pixels) .

The most important benefit, IMO, is that apps that need lens correction would be able to use PT parameters, even if they don't use libpano.

Best, Tom
