An ROI'd image with parameters set to display within the ROI only seem to
work if the top of the ROI is = 384.  Starting with a 2 size ROI in the lower
left hand corner, the bottom 1/4 of the image is correct, with the top 3/4
unchanged, except for horizontal lines at the 1/2 and 3/4 mark.  If the size
of the ROI increases to 1/4 of the image height, then the bottom half displays
correctly.  When it touches the 1/2 image height mark, 3/4 of the image
displays correctly.  I have tried mucking with PageSize to no avail.
The image is a 512x512 TIFF file.  Page size defaults to 65536 pixels.
Has anyone else noticed this behavior?
Any ideas on parameters to change, etc. would be appreciated.
