SCALE_FONT@

Platform

Win32(ClearWin+)

Purpose

To scale the font being used on the current drawing surface.

Syntax

SUBROUTINE SCALE_FONT@( SIZE )
DOUBLE PRECISION SIZE

Description

Rescales the font being used on the current drawing surface.

The scaling involves integer truncation and so is only approximate. A more accurate result may be given by SCALE_FONT1@. This routine uses rounding rather than truncation but is otherwise the same as SCALE_FONT@.

Because of their approximate nature, these functions should not be used in succession and it is recommended that a routine such as SIZE_IN_PIXELS@ be used from time to time in order to set a base size.

Alternatively the subroutine UNSCALE_FONT@(), which takes no arguments, may be called in order to undo the immediately previous call to SCALE_FONT@ or SCALE_FONT1@.
