BitmapSource到BitmapImage

Question

我需要解析Clipboard.GetImage()(a BitmapSource)的内容到a BitmapImage.有谁知道怎么做？

Answer 1

我发现了一个干净的解决方案:

BitmapSource bitmapSource = Clipboard.GetImage();

JpegBitmapEncoder encoder = new JpegBitmapEncoder();
MemoryStream memoryStream = new MemoryStream();
BitmapImage bImg = new BitmapImage();

encoder.Frames.Add(BitmapFrame.Create(bitmapSource));
encoder.Save(memoryStream);

memoryStream.Position = 0;
bImg.BeginInit();
bImg.StreamSource = memoryStream;
bImg.EndInit();

memoryStream.Close();

return bImg;
