Your question does not specify much but here's a few ideas i had:

- What exactly are you modifying? Are you not corrupting the image?

- Make sure that the MemoryStream starting point is at zero (At the beginning of the stream).

C#

ms.Position = 0;

Imge absolutely has a static FromStream method.

Haha how silly of me.. The application I was working on had a property called Image and it did not appear in my list :P

Solution 1

Your first mistake is not giving us the actual error message, or showing us what ms is. I suspect at the core, your error is that ms does not contain a valid image after you finish modifying it. You'd have to post the code for us to know more.
