Drawing graphics text

GDDM V3R2 Base Application Programming Guide

There are two GDDM API calls that enable you to do this; GSCHAR and GSCHAP.

Drawing a line of graphics text at a specified position, using GSCHAR


In "Example: The HOUSE program" in topic 1.4, graphics text was added to the HOUSE example program by means of this call.


     /*          X-COORD  Y-COORD  LENGTH          STRING                */
     CALL GSCHAR( 33.0,     2.0,     28,  'All dimensions are in meters');

GSCHAR writes a string of graphics text of a specified length at a specified position.

As with all graphics calls, the position is given in world coordinates rather than the rows and columns scheme used for alphanumerics.

Drawing a line of graphics text at the current position, using GSCHAP


The GSCHAP call is similar to GSCHAR, but it draws a graphics text string at the current position rather than at a specified one.


     /*          length          string                                  */
     CALL GSCHAP(  28,  'All dimensions are in meters');

This makes it easy to concatenate graphics text strings.
