Data Structures

Description

pset_text_prec creates a text precision value to control how closely the displayed characters adhere to the text representation defined by the workstation-independent text attributes, and the current transformation and clipping values. Depending on the current edit mode, this 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 text precision element.

During structure traversal, the set text precision element sets the specified value for the current text precision entry in the PHIGS traversal state list. If the current text precision ASF entry in the PHIGS traversal state list is INDIVIDUAL, Digital PHIGS uses the text precision value when traversing subsequent text, text 3, annotation text, and annotation text 3 primitives. If the ASF setting is BUNDLED, the value has no effect.

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