Clip
Used to crop a raster image (Clip Boundary), or to define a masked area (Clip Mask).
You can access this tool from the following:
An image can have one clipping boundary, but may have a number of clipping masks. Thus, when you create a new clipping boundary, any existing clipping boundary is cleared. When you create a clipping mask, however, it is added to any existing clipping masks for the selected image. New clipping masks cannot intersect previous clipping masks. If you try to intersect an existing clipping mask, an information box appears to tell you why your clipping mask is invalid.
The valid elements for clipping are circles, ellipses, squares, rectangles, B-splines and closed elements or shapes.
When applying clipping polygons to raster images in a 3D design file, the polygon's shape, used to clip the raster image, is that appearing in the Top view.
