Is the imaqCopyRect() function only intended to be used with the source and destination images having the same dimensions (or at least the same width)? As far as I can tell, the function only seems to work properly when that's the case. Thanks.
Nevermind, I think I figured it out. When calling the imaqGetImageInfo() on the resulting image, you have to pay attention to the pixelsPerLine parameter which may not be the same as the xRes parameter.
