Get a crop of the image from the frame grabber.
Note: this is not configuring the camera sensor to acquire a crop of the image, nor to generate a cropped version of the streaming. Instead, the full image is acquired and then a crop is created from it. If the hardware supports it, it is possible to override this method and request a hardware crop.
cropType | enum specifying how the crop shall be generated |
vertices | the input coordinate (u,v) required by the cropType |
image | the image to be filled |
