Graphics Function: Returns the width in pixels that would be required to print a given string of text (including any trailing blanks) with OUTGTEXT using the current font.
Module: USE DFLIB
Syntax
Results:
The result is of type INTEGER(2). The result is the width of text in pixels if successful; otherwise, -1 (for example, if fonts have not been initialized with INITIALIZEFONTS).
This function is useful for determining the size of text that uses proportionally spaced fonts. You must initialize fonts with INITIALIZEFONTS before calling any font-related function, including GETGTEXTEXTENT.
