SET CHARACTER EXPANSION FACTOR

PSCHXP

CALL SEQUENCE

CALL PSCHXP (CHXP)

INPUT PARAMETERS

REAL CHXP

Defines character width (base). This factor is applied to the height of the character (defined by PSCHH). The default value for this factor is 1.0.

PHIGS STATE

EFFECT

A SET CHARACTER EXPANSION FACTOR 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 EXPANSION FACTOR element. The value specified by CHXP is associated with the element.

When an element of this type is interpreted, the current character expansion factor entry in the PHIGS traversal state list is set to CHXP . This value is used to display the text primitives which follow when the current character expansion factor ASF entry in the PHIGS traversal state list is INDIVIDUAL. When the value is BUNDLED, CHXP has no effect.

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,*)
