The left and upper boarder of the image as well as the width and height can be set. These settings do not effect the image size as determined by is_SetImageSize().

Parameters

hf | Frame grabber handle
xpos | x offset of left boarder (see following table for value range)
ypos | y offset of the upper boarder
xsize | Image width
ysize | Image height
