convert writeablebitmap to bitmapimage

[HDC]

Can the ImageEditor be used to convert a writeablebitmap to a bitmapimage, but without the need to use any sort of graphical interface?

Here is my scenario:

I have a large image (>2MB)
I rescale it to a thumbnail (say 180x180 pixels) so it would consume less memory using a writeablebitmap as output

I now need to convert this writeablebitmap back to a bitmapimage.

Can the imageeditor be of service for this?

Hi Peter,

You can use RadBitmap to resize your images or pass your WriteableBitmap in the constructor. Then export the RadBitmap with the proper format provider to a stream. Finally, pass this stream to the SetSource method of the BitmapImage you want as a result. Here is a sample code on how to do that.

RadBitmap radImage = new RadBitmap(Source);

MemoryStream stream = new MemoryStream();
PngFormatProvider provider = new PngFormatProvider(); // Choose the right FormatProvider.
provider.Export(radImage, stream);

BitmapImage bi = new BitmapImage();
bi.SetSource(stream);
