crop_rectangle1(Image : ImagePart : Row1, Column1, Row2, Column2 : )

描述

算子 crop_rectangle1crop_rectangle1CropRectangle1CropRectangle1CropRectangle1crop_rectangle1 cuts one or more rectangular areas from each of the input images. The areas are indicated by rectangles, which are defined by the coordinates of their upper left and their lower right corners. The upper left corners 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 within the image, then each of the resulting images has the size of its corresponding rectangle.
