BGI Documentation for setfillpattern

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 [WIN]
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;
