函数名: setfillpattern

功 能: 选择用户定义的填充模式

用 法: void far setfillpattern(char far *upattern, int color);

程序例:

#include <graphics.h>

#include <stdlib.h>

#include <stdio.h>

#include <conio.h>

int main(void)

{

/* request auto detection */

int gdriver = DETECT, gmode, errorcode;

int maxx, maxy;

/* a user defined fill pattern */

char pattern[8] = {0x00, 0x70, 0x20, 0x27, 0x24, 0x24, 0x07, 0x00};

/* 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 */

}

maxx = getmaxx();

maxy = getmaxy();

setcolor(getmaxcolor());

/* select a user defined fill pattern */

setfillpattern(pattern, getmaxcolor());

/* fill the screen with the pattern */

bar(0, 0, maxx, maxy);

/* clean up */

getch();

closegraph();

return 0;

}
