crop_part — Cut out one or more rectangular image areas.
The operator crop_part cuts one or more rectangular area from each
of the input images. The areas are indicated by rectangles, which are
defined by the coordinates of their upper left corner and by their size.
The upper left corners of the rectangles must be within the image. At the
right side and at the bottom, the rectangles may exceed the image, but the
domain of the output images is set so that only the part that can be derived
from the input image is contained. If the rectangular areas fall completely
within the image, then each of the resulting images has the size of its
corresponding rectangle.
