setfillpattern

Syntax

#include <graphics.h>
void setfillpattern(char *upattern, int color);

Description

setfillpattern is like setfillstyle, except that you use it to set a user-defined 8x8 pattern rather than a predefined pattern.

upattern is a pointer to a sequence of 8 bytes, with each byte corresponding to 8 pixels in the pattern. Whenever a bit in a pattern byte is set to 1, the corresponding pixel is plotted.

Return Value

None.

Windows Notes

The winbgim version allows the color argument to be an ordinary BGI color (from 0 to 15) or an RGB color.

Example

/* setfillpattern example */ 

#include <graphics.h>
#include <stdlib.h>
#include <stdio.h>
#include <conio.h>

int main(void)
{
   /* request autodetection */
   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\n", 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;
