Jim,

I can see the behavior. The image format is converted from TIFF (gpImageFormatTIFF) to a memory bitmap (gpImageFormatMemoryBMP).

Googling on this behavior I found: https://stackoverflow.com/questions/...view-next-page and that confirms the change. They suggest we make a copy of the image before rotating and display that information. On next or previous page go back to the original file. I guess that is doable but I think quite difficult to implement this in the generic classes as when this happens with a RotateImage would it do the same for one or more other functions. And what to do with a save operation? I bet you want to have the rotated image being saved back in the multi page TIFF file at the original spot.
