2 (STROKE)

PHIGS STATE

EFFECT

A SET TEXT PRECISION 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 TEXT PRECISION element. The value specified by PREC is associated with the element.

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

GPHIGS's software fonts supports the three precisions. For hardware fonts, see GPHIGS user guide for supported precision on each driver.

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,*)
