Constants

Defined Argument     Constant      Description
---------------------------------------------------------------------------
ATALH                PAHNOR        Normal horizontal alignment.  This is
                                   the default value.

                     PACENT        Center horizontal alignment.
                     PARITE        Right horizontal alignment.
 
ATALV                PAVNOR        Normal vertical alignment.  This is the
                                   default value.
                     PATOP         Top vertical alignment.
                     PACAP         Cap vertical alignment.
                     PAHALF        Half vertical alignment.
                     PABASE        Base vertical alignment.
                     PABOTT        Bottom vertical alignment.

Description

PSATAL sets the horizontal and vertical text alignment attributes.  This function creates a set annotation text alignment element that uses the annotation text alignment horizontal and annotation text alignment vertical values to control the positioning of the text extent parallelogram in relation to the text position. The text string remains in the same workstation plane regardless of rotation. 

Depending on the current edit mode, the function either inserts the new structure element directly after the element indicated by the pointer or replaces the element indicated by the pointer. The pointer then points to the new set annotation text alignment element. 

During structure traversal, Digital PHIGS sets the current annotation text alignment entry in the PHIGS traversal state list to the values specified by the horizontal and vertical parameters.  These values are associated with subsequent primitives. 

If Digital PHIGS is in immediate mode, it performs this function immediately, but the function does not create a structure element.
