簡介
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;
}
