Hello Veera,

First of all you should use BitmapImage to store your data and then you should use the CopyPixels method of the BitmapImage class to get access to the bytes itself. Here is a more comprehensive explanation of the CopyPixels method. I hope this will resolve your issue.

Hello Veera,

I didn't see that you were asking about Silverlight. Excuse me. In Silverlight 3 you have the WriteableBitmap class that gives you ability to edit pixels on the fly. Unfortunately, Microsoft has not yet resolved the security issue of editing pixels of an existing image, and thus you are only able to take a snapshot of a control or input the pixels yourself. Rick Barraza has two very interesting topics explaining the use of WriteableBitmap here and here that may be useful in your case. If you share your reasons why you want to edit the pixels of an existing image, maybe we can propose to you a workaround based on our experience. Thank you for contacting us and we look forward to hearing again from you.
