函数名: setusercharsize

功 能: 为矢量字体改变字符宽度和高度

用 法: void far setusercharsize(int multx, int dirx, int multy, int diry);

程序例:

#include <graphics.h>

#include <stdlib.h>

#include <stdio.h>

#include <conio.h>

int main(void)

{

/* request autodetection */

int gdriver = DETECT, gmode, errorcode;

/* initialize graphics and local variables */

initgraph(&gdriver, &gmode, "");

/* read result of initialization */

errorcode = graphresult();

if (errorcode != grOk) /* an error occurred */

{

printf("Graphics error: %s\", grapherrormsg(errorcode));

printf("Press any key to halt:");

getch();

exit(1); /* terminate with an error code */

}

/* select a text style */

settextstyle(TRIPLEX_FONT, HORIZ_DIR, 4);

/* move to the text starting position */

moveto(0, getmaxy() / 2);

/* output some normal text */

outtext("Norm ");

/* make the text 1/3 the normal width */

setusercharsize(1, 3, 1, 1);

outtext("Short ");

/* make the text 3 times normal width */

setusercharsize(3, 1, 1, 1);

outtext("Wide");

/* clean up */

getch();

closegraph();

return 0;

}
