pieslice

Draws and fills in pie slice.

Defined in header <graphics.h>

Syntax

#include <graphics.h>
void  far pieslice(int x, int y, int stangle, int endangle, int radius);

Portability

Remarks

pieslice draws and fills a pie slice centered at {x,y) with a radius given by radius. The slice travels from stangle to endangle. The slice is outlined in the current drawing color and then filled using the current fill pattern and fill color.

The angles for pieslice are given in degrees. They are measured counter-clockwise, with 0 degrees at 3 o'clock, 90 degrees at 12 o'clock, and so on.

Return value

None.

   /* initialize graphics and  local variables V
   initgraph(&gdriver, &gmode,  "");

   /* read result of initialization  7
   errorcode = graphresult ();

/* set fill style  and draw a pie slice */
