BitmapSource到BitmapImage

Question

我需要将Clipboard.GetImage() (一个BitmapSource)的内容解析为一个BitmapImage。有谁知道如何做到这一点吗？

Answer 1

我找到了一个干净利落的解决方案：

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;

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();
