Name

pset_pat_ref_point − Sets the geometric attribute current pattern reference point entry in the PHIGS state list. 

 
Operating States: PHOP, ∗, STOP, ∗
PHIGS standard function
Creates a structure element

Syntax

void pset_pat_ref_point (
  const Ppoint    ∗pat_ref_point    /∗ (I) Pattern reference point ∗/
)

Data Structures

typedef struct {
    Pfloat    x;    /∗ x coordinate ∗/
    Pfloat    y;    /∗ y coordinate ∗/
} Ppoint;

Description

pset_pat_ref_point sets the geometric attribute current pattern reference point entry in the PHIGS state list.  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 reference point element. 

The current pattern reference point attribute represents the starting point for a pattern used to fill the designated area. 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 4.1 does not support this function.
