Clip Underlays
You can use a clipping boundary to clip an underlay.
You can define part of an underlay that you want to display and plot by setting
up a clipping boundary with DGNCLIP, DWFCLIP, PDFCLIP, DGNCLIP,
IMAGECLIP, VPCLIP, and XCLIP. The clipping boundary can be a closed
polyline, rectangle or a polygon with vertices within the overall extents of
the underlay. Each instance of an underlay can only have one clipped
boundary. Multiple instances of the same underlay can have different
boundaries.
Following is an example of an underlay with insets showing polygonal (l) and
rectangular (r) clipping boundaries:
