By clipping an image, you can display and plot only a portion of the image. The clipping boundary can be a rectangle or a two-dimensional polygon with vertices constrained to lie within the boundaries of the image. Multiple instances of the same image can have different clipping boundaries.
Image Clip lets you show only the part of an image you require. Move your cursor over the image to see the clipped portion of the image.
A clip boundary is a display-only feature that you can use for viewing and plotting purposes. It does not permanently change image data. When you delete a clipping boundary, the original image boundary is restored. To clip the image permanently, use an image-editing application such as Autodesk Raster Design.
