SET ANNOTATION TEXT ALIGNMENT

PSATAL

CALL SEQUENCE

CALL PSATAL (ATALH, ATALV)

INPUT PARAMETERS

INTEGER ATALH

Defines annotation text horizontal alignment.

PAHNOR

0 (NORMAL).

PALEFT

1 (LEFT).

PACENT

2 (CENTRE).

PARITE

3 (RIGHT).

INTEGER ATALV

Defines text vertical alignment.

PAVNOR

0 (NORMAL).

PATOP

1 (TOP).

PACAP

2 (CAP).

PAHALF

3 (HALF).

PABASE

4 (BASE).

PABOTT

5 (BOTTOM).

PHIGS STATE

EFFECT

A SET ANNOTATION TEXT ALIGNMENT 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 ANNOTATION TEXT ALIGNMENT element. The values specified by ATALH and ATALV are associated with the element.

When an element of this type is interpreted, the current annotation text alignment entry in the PHIGS traversal state list is set to the parameter. These values are used to display the annotation 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,*)
