显示Flash时控制其的宽度与高度-原创手记-慕课网

Flash在网页显示时，如果不指定其正确的宽度或高度或是按其宽高一定的比例，会变形。

你可以从下面地址参考到怎样取得Flash的宽度或是高度一些信息。http://www.codeproject.com/KB/graphics/ReaderSWFHeader.aspx

为了更好了解，Insus.NET在下面写了一个swf类别(代码部分)

View Code public Swf(int Width, int Height, int ThumbnailSize, string File)
        {

            this._Width = Width;
            this._Height = Height;
            this._ThumbnailSize = ThumbnailSize;
            this._File = File;
        }

        public string Player()
        {
            int f_Width;
            int f_Height;

            if (_ThumbnailSize > 0)  //如果指定Flash缩略显示
            {
                //如果Flash的宽度与高度都小于指定缩略尺寸
                if (_Width < _ThumbnailSize && _Height < _ThumbnailSize)
                {
                    f_Width = _Width; //等于原来的宽度
                    f_Height = _Height;//等于原来的高度
                }
                //如果宽度大于高度
                else if (_Width > _Height)
                {
                    f_Width = _ThumbnailSize;
                    f_Height = _Height * _ThumbnailSize / _Height;
                }
                //如果高度大于宽度
                else
                {
                    f_Width = _Width * _ThumbnailSize / _Height;
                    f_Height = _ThumbnailSize;
                }
            }
            else
            {
                f_Width = _Width;
                f_Height = _Height;
            }

            return @"<object classid='clsid:D27CDB6E-AE6D-11cf-96B8-444553540000' codebase='http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,19,0'width=" + f_Width + " height=" + f_Height + ">"
            + @" <param name='movie' value=" + _File + ">"
            + @" <param name='quality' value='high'>"
            + @"<embed src=" + _File + " quality='high' pluginspage='http://www.macromedia.com/go/getflashplayer' type='application/x-shockwave-flash' width=" + f_Width + " height=" + f_Height + "></embed>"
            + @" </object>";
        }

xxx.aspx使用：

<asp:Literal ID="Literal1" runat="server"></asp:Literal>

xxx.aspx.cs:

View Code //codeproject下载的Flash类别，Insus.NET曾经修改过，改为FlashInfo，基本是一样的，只不过添加一些自己的属性。
                FlashInfo objFlashInfo = new FlashInfo(Server.MapPath(file));
                Swf objSwf = new Swf(objFlashInfo.Width, objFlashInfo.Height,400, file);
                this.Literal1.Text = objSwf.Player();
