头文件graphics.h包含fillellipse()函数,该函数绘制并填充以(x,y)和(x_radius,y_radius)为中心的椭圆作为x和y半径。句法:
void fillellipse(int x, int y, int x_radius, int y_radius); where, (x, y) is center of the ellipse. (x_radius, y_radius) are x and y radius of ellipse.
例子:
Input:x = 200, y = 200, x_radius = 50, y_radius = 90 Output: Input:x = 300, y = 250, x_radius = 100, y_radius = 70 Output:
下面是fillellipse()函数的实现:
// C Implementation for fillellipse()
#include <graphics.h>
// driver code
int main()
{
// gm is Graphics mode which is
// a computer display mode that
// generates image using pixels.
// DETECT is a macro defined in
// "graphics.h" header file
int gd = DETECT, gm;
// initgraph initializes the
// graphics system by loading a
// graphics driver from disk
initgraph(&gd, &gm, "");
// fillellipse function
fillellipse(200, 200, 50, 90);
getch();
// closegraph function closes the
// graphics mode and deallocates
// all memory allocated by
// graphics system .
closegraph();
return 0;
}
