SET CHARACTER EXPANSION FACTOR

PSET_CHAR_EXPAN

CALL SEQUENCE

void pset_char_expan(

Pfloat	exp_factor	/* character expansion factor 	*/

)

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 exp_factor 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 exp_factor. 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, exp_factor 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,*)
