Name

PSPA − Specifies the height and width vectors of a pattern. 

Operating States: PHOP, ∗, STOP, ∗
PHIGS standard function

Description

PSPA specifies the geometric attribute current pattern size entry in the PHIGS state list, which is the height and width vectors in world coordinate units.  Depending on the current edit mode, this function either inserts the new structure element directly after the element indicated by the pointer or replaces the element indicated by the pointer.  The pointer then points to the new set pattern size element. 

Digital PHIGS begins replicating the pattern representation at the pattern reference point, and continues until the polygonal fill area in the world coordinate space is full. Digital PHIGS uses this value for all subsequent calls to fill area functions until you specify another value. 

If Digital PHIGS is in immediate mode, it performs this function immediately, but the function does not create a structure element. 

Digital PHIGS Version 3.1 does not support this function.
