SET CHARACTER UP VECTOR

PSCHUP

CALL SEQUENCE

CALL PSCHUP (CHUX, CHUY)

INPUT PARAMETERS

REAL CHUX, CHUY

These values expressed in TLC (Text local coordinates) define the text height vector. The base vector is defined from this data as being of any length and forming a right angle with the height vector in the clockwise direction.

PHIGS STATE

EFFECT

A SET CHARACTER UP VECTOR element is inserted in the open structure after element pointer or replaces the element indicated by element pointer, depending on edit mode. Element pointer then points to the SET CHARACTER UP VECTOR element. The value specified by CHUX,CHUY is associated with the element.

When an element of this type is interpreted, the current character up vector entry in the PHIGS traversal state list is set to CHUX,CHUY. This value is used to display the text primitives which follow.

EXTENSION TO THE PHIGS STANDARD

If GPHIGS is in NRS mode, the effect of this function is different from the effect described in the standard.

In NRS mode, (see OPEN PIPE), the element is not stored in a structure. It is sent to the workstation on which the pipe is opened.

ERRORS

5

Ignoring function, function requires state (PHOP,*, STOP,*)
