setusercharsize

Syntax

#include <graphics.h>
void setusercharsize(int multx, int divx, int multy, int divy);

Description

setusercharsize gives you finer control over the size of text from stroked fonts used with graphics functions. The values set by setusercharsize are active only if charsize equals 0, as set by a previous call to settextstyle.

With setusercharsize, you specify factors by which the width and height are scaled. The default width is scaled by multx : divx, and the default height is scaled by multy : divy. For example, to make text twice as wide and 50% taller than the default, set

multx = 2;  divx = 1;
multy = 3;  divy = 2;

Return Value

None.
