{
    Bitmap bitmap = new Bitmap(intBitmapWidth, intBitmapHeight);
    Graphics g = Graphics.FromImage(bitmap);
    
    //바탕 화면 경로
    string desktopPath = Environment.GetFolderPath(Environment.SpecialFolder.Desktop) + @"\Test"; 
    g.CopyFromScreen(ptSource, new Point(0, 0), new Size(intBitmapWidth, intBitmapHeight));
	
    //폴더 생성
    DirectoryInfo di = new DirectoryInfo(desktopPath);
    if (di.Exists == false) di.Create();
	
    //이미지 저장 경로
    bitmap.Save(@desktopPath + @"\test.png", ImageFormat.Png);
