Autostitch question

I've been reading about Panorama Tools and I decided to give Autostitch
a try:
http://www.autostitch.net/

Rather than working with photographs I scanned a paper map on my
scanner. It consists of 21 JPEG's. Autostitch put them all together
correctly. Amazing! I'm impressed.

Only one thing I can't figure out. The final big JPEG is warped, as if
peeled off of a sphere. I can see where this might be needed with
photographs having lens distortions and all. But I'm working with flat
undistorted scanned images. The end big JPEG should not be warped.

Autostitch has a bunch of stitch option settings, which I don't
understand, settings like Theta, Phi, Psi. Is there a setting that
would prevent or reduce the warping of my flat images?

Thanks for your help.

I can't speak about autostitch since I don't use it, but many stitching
programs handle the case of scanned images differently then photos and
will give you a very good non-distorted final image. There is a check
box to tell the program that you are stitch from a scanned source.

==========================================

Got any program recommendations?

Every other program I've tried so far barfs. My scanned images are all
different sizes and have different quantities of images in each row. In
other words my source image is not rectangular.

The Panorama Tools can do this, sort of, but with great effort. It's
easier to do it manually in a graphics program:

I got photostich with my first Canon digital camera. It comes with all Canon
cameras. However I don't believe you can buy it. You may have to borrow
someone's canon install cd. You don't need a Canon camera to use it.
It has a selection for scanned in objects. I used it to put together a map
also. It was about 16 pieces. Worked great.

You want the planar projection instead of the spherical one.

However, from the web site:

Q: What projection method does AutoStitch use? Does it support full view
panoramas?

A:The demo version of AutoStitch uses sperical projection and is capable
of stitching full view 360 x 180 degree panoramas (everything visible
from a point). Cylindrical and planar projections are not supported in
the demo version.
