Frank,

the files are OK, if they are re-read the display error disappears. Therefore I would say that

  1. there is a bug in our code for displaying the image data, or
  2. sometimes we have read errors from the disk

As we see these errors only with Packbits I would rule out no. 1. Is it possible to have sporadic read errors on modern computers that would cause bit errors during image decoding? The images are quite big, up to several 100MB.

best regards
Bernd
