Description:
Inquire if the members of
the array of test points are obscured by any picture overlying (create more recently than)
the current picture. The points are defined in the world coordinate system of the current
picture. An array of logical values is returned containing true if the corresponding point is
obscured, otherwise false.
Invocation
CALL AGI_ITOBS( NXY, X, Y, LTOBS, STATUS )
Arguments
NXY = INTEGER (Given)
Number of test points
X = REAL(NXY) (Given)
Array of x coordinates of test points
Y = REAL(NXY) (Given)
Array of y coordinates
of test points
LTOBS = LOGICAL(NXY) (Returned)
Array of results. True if point is
obscured, otherwise false.
STATUS = INTEGER (Given and Returned)
The global status
