一个自动动态播放图片的类（downmoon）

一个自动动态播放图片的类（downmoon）第一步：创建一个类clsTurnPicture

增加方法如下：

/// <summary>

/// 播放图片类(downmoon)

/// </summary>

/// <param name='arrImgName'>arrImgName</param>

/// <param name='arrDesc'>arrDesc</param>

/// <param name='strShopName'>strShopName</param>

/// <param name='strBrandName'>strBrandName</param>

/// <param name='strResoourceCode'>strResoourceCode</param>

/// <param name='ScrWidth'>ScrWidth</param>

/// <param name='ScrHeight'>ScrHeight</param>

/// <param name='PicWidth'>PicWidth</param>

/// <param name='PicHeight'>PicHeight</param>

/// <param name='TextHeight'>TextHeight</param>

/// <param name='ToolBarHeight'>ToolBarHeight</param>

/// <param name='FontSize'>默认为16,px</param>

/// <returns></returns>
