函数名:setfillstyle
功 能: 设置填充模式和颜色
用 法:void far setfillstyle(int pattern, int color);
程序例:
#include <graphics.h>
#include <stdlib.h>
#include <string.h>
#include <stdio.h>
#include <conio.h>
/* the names of the fill styles supported */
char *fname[] = { "EMPTY_FILL",
"SOLID_FILL",
"LINE_FILL",
"LTSLASH_FILL",
"SLASH_FILL",
"BKSLASH_FILL",
"LTBKSLASH_FILL",
"HATCH_FILL",
"XHATCH_FILL",
"INTERLEAVE_FILL",
"WIDE_DOT_FILL",
"CLOSE_DOT_FILL",
"USER_FILL"
};

/* read result of initialization */

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 */
}
midx = getmaxx() / 2;
midy = getmaxy() / 2;
for (style = EMPTY_FILL; style < USER_FILL; style++)
{
/* select the fill style */
setfillstyle(style, getmaxcolor());
/* convert style into a string */
strcpy(stylestr, fname[style]);
/* fill a bar */
bar3d(0, 0, midx-10, midy, 0, 0);
/* output a message */
outtextxy(midx, midy, stylestr);
/* wait for a key */
getch();
cleardevice();
}
/* clean up */
getch();
closegraph();
return 0;
}
颜色填充：
1）SOLID_FILL 单色实填充
2）LINE_FILL 用“-”填充
3）HATCH_FILL 用方网格填充
4）XHATCH_FILL 用斜方格填充
5）WIDE_DOT_FILL用稀疏点填充
6）CLOSE_DOT_FILL用密集点填充
