astGetRegionBounds

Returns the bounding box of Region

Description:

This function returns the upper and lower limits of a box which just encompasses the supplied Region. The limits are returned as axis values within the Frame represented by the Region. The value of the Negated attribute is ignored (i.e. it is assumed that the Region has not been negated).

Synopsis

void astGetRegionBounds( AstRegion this, double lbnd, double ubnd )

Parameters:

this
Pointer to the Region.
lbnd
Pointer to an array in which to return the lower axis bounds covered by the Region. It should have at least as many elements as there are axes in the Region. If an axis has no lower limit, the returned value will be the largest possible negative value.
ubnd
