Syntax
INT is_SetVideoSize (HIDS hf, INT xpos, INT ypos, INT xsize, INT ysize)
Description
Using is_SetVideoSize() the area from the video signal to be digitized can be defined. This adjusts the digitization area to non-standard camera signals. 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().
