Issue with Setting Region of Interest on Ultrasound Image

[r201]

Hi!

I am using fCal to synchronize data from a frame grabber (Razer Ripsaw X) and the Aurora motion tracking system. Since the frame grabber captures everything displayed on the ultrasound screen, I was trying to apply a clipping process to work exclusively with the ROI of the ultrasound images.

The issue arises when I apply the clipping directly to the input image — I can no longer visualize the image correctly in fCal. However, if I save the image and open it in Slicer, it appears correctly. The problem is that after applying this initial clipping to the received frames, when I try to define a second window in the segmentation parameters, I am never able to do so. It seems that whatever window I define, the system assumes an incorrect one, ultimately crashing the fCal program. I have already tried segmentation windows such as:
ClipRectangleOrigin="575 123" ClipRectangleSize="320 460" or ClipRectangleOrigin="5 5" ClipRectangleSize="310 450", but none of them work as expected.

On the other hand, if I only define the window using the segmentation parameters (i.e., setting ClipRectangleOrigin="x y" ClipRectangleSize="x y"), everything works fine. The only issue is that I am forced to receive the entire ultrasound image beforehand. Please find attached the XML script I am using. I am currently working with version 2.8.0.

Would anyone be able to help me with this problem? I would be very grateful!
