This command allows the selection of an image and a contour (closed polyline) and the creation of a new image with the area which encompasses said contour. The command will request the destination directory of the resulting image. The original image will be undone from the drawing and replaced by the new image.
On AutoCAD there is a similar command called Delimit > Image, but the difference with this other one is that in AutoCAD it conceals the image area which is situated on the exterior of the contour, the modification is only saved in the drawing and this command cuts away the image and creates a new one with the result.
