graphdefaults function in c

graphdefaults function resets all graphics settings to their defaults.

Declaration: void graphdefaults();

It resets the following graphics settings :-

  • Sets the viewport to the entire screen.
  • Moves the current position to (0,0).
  • Sets the default palette colors, background color, and drawing color.
  • Sets the default fill style and pattern.
  • Sets the default text font and justification.

C programming source code for graphdefaults

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

main()
{
   int gd = DETECT, gm;

   initgraph(&gd, &gm, "C:\\TC\\BGI");

   setcolor(RED);
   setbkcolor(YELLOW);

   circle(250, 250, 50);

   getch();
   graphdefaults();

   getch();
   closegraph();
   return 0;
}

In the above program we have first changed the drawing color to RED and background color to YELLOW and then drawn a circle with (250, 250) as center and 50 as radius. When the user will press a key graphdefaults is called and both drawing and background color will be reset to their default values i.e. WHITE and BLACK respectively. See colors in C graphics.
