函式名: settextstyle
函式原型:void far settextstyle(int font, int direction, char size);
font 為字型:DEFAULT_FONT, TRIPLEX_FONT, SMALL_FONT, SANSSERIF_FONT, GOTHIC_FONT,也可以用0 ~ 4代替。
direction 為字元的排列方向:橫向和豎向,0為橫向排列,1為豎向排列。
size 為字型大小:可用interger做參數。

程式例

#include <graphics.h>
#include <stdlib.h>
#include <stdio.h>
#include <conio.h>
/* the names of the text styles supported */
char *fname[ ] = { "DEFAULT font",
"TRIPLEX font",
"SMALL font",
"SANS SERIF font",
"GOTHIC font"
};
int main(void)
{
/* request auto detection */
int gdriver = DETECT, gmode, errorcode;
int style, midx, midy;
int size = 1;
/* initialize graphics and local variables */
initgraph(&gdriver, &gmode, " ");
/* read result of initialization */
errorcode = graphresult( );
if (errorcode != grOk) /* an error occurred */
{
printf("Graphics error: %s\n", grapherrormsg(errorcode));
printf("Press any key to halt:");
getch( );
exit(1); /* terminate with an error code */
}
midx = getmaxx( ) / 2;
midy = getmaxy( ) / 2;
settextjustify(CENTER_TEXT, CENTER_TEXT);
/* loop through the available text styles */
for (style=DEFAULT_FONT; style<=GOTHIC_FONT; style++)
{
cleardevice( );
if (style == TRIPLEX_FONT)
size = 4;
/* select the text style */
settextstyle(style, HORIZ_DIR, size);
/* output a message */
outtextxy(midx, midy, fname[style]);
getch( );
}
/* clean up */
closegraph( );
return 0;
