AST_BOUNDINGBOX
-
Return a bounding box for previously drawn graphics
- Description:
- This routine returns the bounds of a box which just encompasess the
graphics produced by the previous call to any of the Plot methods
which produce graphical output. If no such previous call has yet
been made, or if the call failed for any reason, then the bounding box
returned by this routine is undefined.
- Invocation:
- CALL AST_BOUNDINGBOX( THIS, LBND, UBND, STATUS )
- Arguments:
-
THIS = INTEGER (Given)
-
Pointer to the Plot.
-
LBND( 2 ) = REAL (Returned)
-
A two element array in which is returned the lower limits of the
bounding box on each of the two axes of the graphics coordinate
system (the base Frame of the Plot).
-
UBND( 2 ) = REAL (Returned)
-
A two element array in which is returned the upper limits of the
bounding box on each of the two axes of the graphics coordinate
system (the base Frame of the Plot).
-
STATUS = INTEGER (Given and Returned)
-
The global status.
- Notes:
- An error results if the base Frame of the Plot is not
2-dimensional.
