Adjust Colors for Background
Adjust Colors for Background controls whether the underlay colors are visible
against the drawing background color. The default setting of Yes indicates
that the background colors of the underlay and the drawing environment are
analyzed to see if they are both light or both dark, or is one dark and the other
light. When one background is light and the other dark, the colors of the
underlay are inverted so the underlay is displayed. If the setting is changed
to No or Off, the original colors of the underlay are used. Depending on the
background colors, the underlay might not be visible.
Clip PDF Underlays
You can use a clipping boundary to clip a PDF underlay.
You can define part of an underlay that you want to display and plot by setting
up a clipping boundary with PDFCLIP, 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:
