Is it possible to convert a byte[] to a bitmapsource?

问题

So far I have:

using (MemoryStream ms = new MemoryStream(imageData))
{
     Bitmap img = (Bitmap)Image.FromStream(ms);
}

And then I would imagine I would be able to get a BitmapSource from img somehow? If this is totally wrong please feel free to correct me.

回答1:

Try using BitmapSource.Create(). But you need to create pallete first:

var colors = new List<Color>();
colors.Add(Colors.Red);
colors.Add(Colors.Blue);
colors.Add(Colors.Green);
var palette = new BitmapPalette(colors);

Got the easiest solution:

using (MemoryStream ms = new MemoryStream(imageData))
{
    BitmapDecoder bitmapDecoder = BitmapDecoder.Create(ms, BitmapCreateOptions.PreservePixelFormat, BitmapCacheOption.OnLoad);
    BitmapSource photo = new WriteableBitmap(bitmapDecoder.Frames.Single());
}

Haven't tested it yet but my code was taken from: Here
