BitmapSource to BitmapImage

Question

我需要解析Clipboard.GetImage()（a BitmapSource）的內容爲BitmapImage。 有誰知道這是怎麼做到的？

Answer 1

我已經找到了一個乾淨的解決方案，它的工作原理：

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; 

Answer 2

using System.IO; // namespace for using MemoryStream 

private static byte[] ReadImageMemory() 
{ 
    BitmapSource bitmapSource = BitmapConversion.ToBitmapSource(Clipboard.GetImage()); 
    JpegBitmapEncoder encoder = new JpegBitmapEncoder(); 
    MemoryStream memoryStream = new MemoryStream(); 
    encoder.Frames.Add(BitmapFrame.Create(bitmapSource)); 
    encoder.Save(memoryStream); 
    return memoryStream.GetBuffer(); 
} 

// and calling by this example........ 
byte[] buffer = ReadImageMemory();
