ROIPosition

18-37

Note: The Width does not include both end points as well as the width between the

pixels. It includes one end point, plus the width between pixels. For example, if you want

to capture an ROI of pixels 20 through 30, including both end pixels 20 and 30, set an

XOffset of 19 and a Width of 11. The same rule applies to height.

In the figure shown above, the width of the captured ROI contains pixels 51 through 170,

including both end points, because the XOffset is set to 50 and the Width is set to 120.
