ah thanks it worked!

maybe a noob question. I have a png image that the user can copy programmatically to the clipboard in Windows (this is a wpf client application). When the user pastes this image somewhere else, the background is black. I had converted this image from ico to png using paint.net. I understand this happens because the background layer is transparent. One way would be to set the background layer to white. I can't work out how to do this. Some png images don't have this problem and I examined them but I can't see the differences
