如何画有填充色的圆圈

各位大虾好：
        请问一下，有没有画有填充色的圆圈的算法，最好有代码，多谢！

/*---------------------------------------------------------------------------
功能：    画圆 并以颜色填充
        
        rad_ 是被填充的半径，<=rad
        rad_ =0 全填充， =rad-1 不填充    =rad 不画
        
        著名的bresenham画圆算法
---------------------------------------------------------------------------*/
void lcd_fill_circle(unsigned int row, unsigned int column, unsigned int rad, unsigned int color,
                     unsigned int rad_ )

{
  signed long   D;/* Decision Variable */
  unsigned long CurX;/* Current X Value */
  unsigned long  CurY;/* Current Y Value */
  
  unsigned int i = 0;
  
  for (i = rad; i > rad_; i--)
  {
  //以下开始画一个圆
  D =3 - (i << 1); //3 - (rad << 1);
  CurX = 0;
  CurY = i;//rad;
  
  while (CurX <= CurY)
  {
    Lcd_SetCursor(row + CurX, column + CurY);
    SdCmd(0x0202);
    SdData(color);

    Lcd_SetCursor(row + CurX, column - CurY);
    SdCmd(0x0202);
    SdData(color);

    Lcd_SetCursor(row - CurX, column + CurY);
    SdCmd(0x0202);
    SdData(color);

    Lcd_SetCursor(row - CurX, column - CurY);
    SdCmd(0x0202);
    SdData(color);

    Lcd_SetCursor(row + CurY, column + CurX);
    SdCmd(0x0202);
    SdData(color);

    Lcd_SetCursor(row + CurY, column - CurX);
    SdCmd(0x0202);
    SdData(color);

    Lcd_SetCursor(row - CurY, column + CurX);
    SdCmd(0x0202);
    SdData(color);

    Lcd_SetCursor(row - CurY, column - CurX);
    SdCmd(0x0202);
    SdData(color);

    if (D < 0)
    {
      D += (CurX << 2) + 6;
    }
    else
    {
      D += ((CurX - CurY) << 2) + 10;
      CurY--;
    }
    CurX++;
  }
  //

  }
}


注：这是我用stm32时写的，看一下算法还是可以的，效果还不错。将就着看吧。
