- 3.2.4 CHANGE VIEWPORT
-
-
- The CHANGE VIEWPORT command is used to change the clipping rectangle or
- boundary of a viewport. The clipping rectangle for a viewport can only be
- made smaller than its original definition. Once a viewport has been defined,
- its size cannot be increased.
-
-
- COMMAND FORMAT
-
- #CHANGE VIEWPORT :View x1 :Loc x2 x3
-
- or
-
- #CHANGE VIEWPORT FULL :View x1
-
- If the FULL modifier is omitted, the required view is identified by 'x1'.
- The two locations 'x2' and 'x3' define the extents of a window which will
- become the new clipping rectangle for the viewport. The window definition
- must be inside the identified viewport. ( See fig. 3.5 ).
-
-

- rectangle to its full size - the original viewport definition
- size. The viewport can be identified via IDENTS, or the
