Auto Rotation

Hello All,

I've written many manipulation algorithms for our software using IM for
things like scaling, enhancing, binarizing, and rotation, all based on
pre-set thresholds.  Works great, thanks for all the work in IM!

But, now I'm at a point where I need to rotate a binarized image to be
square, without having any kind of pre-set thresholds.

Is there anything like this, an auto-rotation mechanism within IM???

If not, can anybody point me in the direction of C++ code that might come
close to what I need to do?

Thanks,
