SET TEXT ALIGNMENT

PSTXAL

CALL SEQUENCE

CALL PSTXAL (TXALH, TXALV)

INPUT PARAMETERS

INTEGER TXALH

Defines the horizontal alignment of the text.

PAHNOR

0 (NORMAL).

PALEFT

1 (LEFT).

PACENT

2 (CENTRE).

PARITE

3 (RIGHT).

INTEGER TXALV

Defines the vertical alignment of the text.

PAVNOR

0 (NORMAL).

PATOP

1 (TOP).

PACAP

2 (CAP).

PAHALF

3 (HALF).

PABASE

4 (BASE).

PABOTT

5 (BOTTOM).

PHIGS STATE

EFFECT

A SET 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 TEXT ALIGNMENT element. The values specified by TXALH,TXALV are associated with the element.

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