imaq 7.0 display indicator problem

[Rikske]

When I zoom in and then move an earlier drawn ROI my image shifts horizontally to the left. At that stage it is impossible to move the ROI to the right side.Up and down is no problem.
I wanted to make a small vi to show you the problem, but it seems that the error does not occure every time.

Is this known and is there a solution?

When you zoom in on the image, the shape of the ROI overlay is preserved rather than mapped into individual pixels. Therefore the ROI may look shifted from its place of origin. However, the data is still okay, which can be demonstrated by using either IMAQ Merge Overlay VI or using IMAQ ROIToMask VI.

Does this explain the behavior you are seeing?
