Hmm, I browse/sort my images with gqview, and press a key to rotate the
images with jpegtran. quite fast, and browsing them once is needed anyway to
judge the quality.

If I just rotate the view inside hugin, PTOptimizer will estimate roll=90
for usual images, if I feed the coordinates, like they are in the image
(for example, swap x,y, when invoking PTOptimizer)

Otherwise if I use x,y like the user selects them, I would have to rotate
the image file (which I do not want to do), so that PTStitcher can work with
the real (rotated) y,p,r values.

Or I would have to adjust the r,p,y values to match the nonrotated image
files that PTStitcher reads. If I remember correctly, r is applied after all
other rotations, so a simple r +- 90 deg wouldn't work.

I haven't looked how other frontends handle this.

You are right. I probably should use your software. Didn't know about it
when I looked at how to rotate the jpg's.
