setfillstyle

Syntax of setfillstyle

#include <graphics.h>
void setfillstyle(int pattern, int color);
 

Description of setfillstyle

setfillstyle sets the current fill pattern and fill color. To set a user-
defined fill pattern, do not give a pattern of 12 (USER_FILL) to
setfillstyle; instead, call setfillpattern.
If invalid input is passed to setfillstyle, graphresult returns -1
(grError), and the current fill pattern and fill color remain unchanged.
Note: The EMPTY_FILL style is like a solid fill using the current
background color (which is set by setbkcolor).

Example of setfillstyle

/* setfillstyle example */
 
#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" };
 
int main(void)
{
   /* request autodetection */
   int gdriver = DETECT, gmode, errorcode;
   int style, midx, midy;
 
   char stylestr[40];
 
 
   /* 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;
 
   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;
}
