Paint.NET :: Adding Alpha Channel For Transparent Backgrounds?

what I have been doing to work with transparency: bring up GIMP to add an alpha channel and set part of an image to transparent. Save and use in Paint.net.Today, for example, I wanted to create a M + W logo, and the result looked like this:I set the font to Engravers MT, put a red W on an image.Selected "All", copied to clipboard, then pasted to a new image.Vertically flipped the new image, making it an M, changed color to blue using Recolor tool. Saved it as PNG, closed image.Started GIMP, opened the blue M image.On GIMP menu, selected Layer --> Transparency --> Add Alpha ChannelUsed Fuzzy Select Tool to select the area outside the blue MHit delete key to remove color of fuzzy selection (converting it to transparent)Save image as PNG and exit GIMP.Back in Paint.net, open the M image.Select All of Image, copy to clipboard.Paste into New Layer of W image.Adjust position of this transparent selection layer to achieve desired resutl as above.Save the completed image.I find GIMP to be very hard to work with, and prefer working with Paint.net. It would be so nice to be able to create an alpha channel and make a transparent area of an image inside of Paint.net.
