- 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.
