Use GPTXFO to insert a Set Text Font structure element into the open structure following the element pointer or to replace the element pointed at by the element pointer with a Set Text Font structure element depending on the current edit mode.
This structure element specifies a font identifier that the graPHIGS API uses to render all subsequent annotation and geometric text primitives. At structure traversal time, the graPHIGS API uses this identifier when the text font aspect source flag is set to 2=INDIVIDUAL
The traversal default for annotation and geometric text font is font 1.
If a value is encountered that is unavailable (unsupported or inactive), font 1 of that character set is substituted. If that font is unavailable, font 1 of the primary character set is substituted at the same precision.
For a complete list of supported fonts, see The graPHIGS Programming Interface: Technical Reference For specific workstation support, use Inquiry programming subroutines ( Chapter 16. "Inquire Subroutines" or see The graPHIGS Programming Interface: Technical Reference )
