Screenshot with alpha value

Wavewash: your program/code is rather helpful to me.

The idea I had in mind was to have a translucent background and perhaps some objects on top with some varying degrees of opacity. Obviously, when whatever is rendered in the scene, the whole screen will have a background and be opaque, but I wanted to have the option of making parts of it "see-thru" when writing what is on screen to some type of image format. I wasn''t exactly sure how to go about writing the screenshot out to a non .bmp file but your code, Wavewash, and some code snippets on MSDN have demystified some things for me. I''m using this for some non-game stuff which isn''t too complex as far as how much and what is on screen. It won''t really be a "screenshot" in the typical sense, I guess, and I think it will be feasible to be able to do what I''m going for.
