XPRINT TEXT SIZE statement

Purpose

Calculate the size of text to be printed on a host printer.

Syntax

XPRINT TEXT SIZE txt$ TO nWidth!, nHeight!

Remarks

This statement calculates the total size of the printed text, based upon the current font for the host printer.  The sizes returned are specified in pixels, unless optional world coordinates have been defined with an XPRINT SCALE statement.

This allows you to easily calculate the appropriate print position, particularly when using a proportional font.  If this statement is executed without a host printer attached, error 57 is generated.
