Question

I want to convert BitmapImage to byte[] in windows 8 application. I know how to do it using windows sdk but can’t seem to get it working for WinRT sdk.

One or two posts are suggesting that I should use WritableBitmap to achieve that but there are no clear examples.

Conversion of BitmapImage to Byte array (Windows)

following is the best I found but still too vague for me

WinRT Loading an Image into a Byte array

I’ll appreciate any help.

You should look at the WriteableBitmapEx project here – http://writeablebitmapex.codeplex.com/ It is discussed here – WinRT Loading an Image into a Byte array… from the answer…

Basically you need to load the image into a WriteableBitmap, then
access its pixel buffer by calling PixelBuffer.AsStream().
