Dear David,

thank you very much for your answer. Your code did it and you were right, the
TIFF-file was a 3 x m x n array.

Just the last question: How can I split the image into three 2-dim arrays and
after working with them to create again a 3 x m x n array (TIFF-file) with
these three new files?

Thanks again for your help!!!

Harald
