Circles (ifm::Circle)

ifm::Circle c ( int x, int y, int r);
	Creates a circle with center (x, y) and radius r.

int	c.x ()	Returns center's x-coordinate.
int	c.y ()	Returns center's y-coordinate.
int	c.r ()	Returns radius of c.

Example

The following code draws a circle with center (100, 100) and radius 20. Then it waits for a mouseclick to finish.

#include <IFM/window>

int main()
{
    ifm::wio << ifm::Circle(100, 100, 20) << ifm::flush;
    ifm::wio.wait_for_mouse_click();
    return 0;
}
