Moving ROI in real-time

In the attached patch I'm trying to move the ROI in real time using a clock....

I have generated 2D int rect coordinates. If I use them to draw a rect it works, but if I try to use them in the SetROI I can see the coordinates changes in the properties windows, but in the directx display I can see only the first frame.

Please help....

Since you are reading a static image, not a video file, the videofilereader just reads 1 frame and then stops; thus, the lower display is never refreshed. You can synchronize the videofilereader with the clock generator.

See the attached patch.
