I am posting for a co-worker.  He asks:

  Could you please enquire on the network whether some body has a fast
  algorithm for rotating by 90 degrees very very large monochrome or
  multichannel images. The problem is nontrivial and probably can be
  handled by exchanging in and out of a limited size buffer that can be
  stored in high speed memory. I have an urgent need for this if we can
  find one.

Please repond with Email to cristy@dupont.com.  Thanks in advance.
