- If I apply an ROI to an image and display it, the results are fine IF
- I set the valid region to that outside the ROI, i.e.
- roi = ilRectRoiCreate(100,100,150,30,512,512,0);
-
- However, if I set the valid region to be within the ROI
- roi = ilRectRoiCreate(100,100,150,30,512,512,1);
- The top half of the image is garbage, although the bottom half
- is OK.
- The image is a 512x512 TIF file.
-
- Any pointers here would be greatly appreciated.
