What's a good 2D graphics drawing API for Windows/C++?

I've been working on a small little application, and I've been using DirectX/3D to draw textures to the screen (all 2-dimensional elements). The API, I find, is pretty easy to use and to incorporate using OOP principles, but I can't help but feel that using DirectX on something this small is insanely over-kill.

I can't seem to find consensus on a good alternative, though. Any suggestions?

EDIT: Native alpha-blending and PNG file support is necessary.

With much first-post love, Jengerer

I have used Gosu in the past, and it has been alright to work with. It was designed to be used more with Ruby, but it is not bad for C++. We used it in a quick side scroller game, where we messed with z-order and the alpha channel. It might be worth checking out.

If you need alpha blending you have to use the graphics hardware; the only good way to do that is to use a 3D API similar to how you're doing it now (DirectX or OpenGL). Any alternative (GDI/+ or say, DirectDraw) will not use the full graphics hardware for accelerating blending and will have to perform it on the CPU, greatly reducing performance.

As mentioned, Direct2D is an option also--it is functionally a layer on top of Direct3D that supports more 2D specific functionality as well as excellent text support.

Windows includes one out of the box. (GDI32.DLL). It's possible to hook into the WM_PAINT message in the WindowProc call and use BeginPaint() to start drawing. A really good idea of what can be done and a basic tutorial is available on Zetcode.

If you don't need XP support, use Direct2D.
Otherwise, use GDI+.
