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)
