BitmapImage to byte[] Windows 8 metro (WinRT)

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.

Answer 1

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().

Answer 2

All you need is:

• BitmapDecoder.GetPixelDataAsync()
• PixelDataProvider.DetachPixelData()

And then you have a byte array of BitmapImage!
