在Wpf中使用動態GIF影象的簡單方法
阿新 • • 發佈:2019-01-07
Wpf本身的方法如果想載入GIF影象實在是過於複雜,我們可以通過使用winform控制元件,減少複雜性
方法一:利用winform控制元件
System.Windows.Forms. PictureBox pb = new System.Windows.Forms.PictureBox()
{
Width = 200, Height = 150, SizeMode = PictureBoxSizeMode .CenterImage
};
pb.Image = System.Drawing. Image.FromFile (@"C:\Users\zez\Desktop\201203161640295.gif" );
System.Windows.Forms.Integration. WindowsFormsHost wfh = new System.Windows.Forms.Integration.WindowsFormsHost ();
wfh.Child = pb;
grid.Children.Add(wfh);
注 :System.Windows.Forms.Integration名稱空間在V3.0中,有時需要單獨新增引用 C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\v3.0 \...
方法二:只能讀取第一幀
BitmapImage img = new BitmapImage();
img.BeginInit();
img.UriSource = new Uri (@"C:\Users\zez\Desktop\201203161640295.gif");
img.DecodePixelWidth = 200;
img.EndInit();
Border bor = new Border() { Width=300 ,Height=200 ,HorizontalAlignment= System.Windows .HorizontalAlignment .Left};
bor.Background = new ImageBrush (img);
grid.Children.Add(bor);
方法三:使用解碼器
Uri myUri = new Uri("tulipfarm.bmp", UriKind.RelativeOrAbsolute);//(第二個引數指定Uri地址)
GifBitmapDecoder decoder2 = new GifBitmapDecoder(myUri, BitmapCreateOptions.PreservePixelFormat, BitmapCacheOption.Default);
通過decoder2.Frames可以獲取gif所有幀,然後存入集合,迴圈播放,
