C語言 fillellipse()用法及代碼示例

頭文件graphics.h包含fillellipse()函數，該函數繪製並填充以(x，y)和(x_radius，y_radius)為中心的橢圓作為x和y半徑。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:

下麵是fillellipse()函數的實現：

// 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; 
}
