Direct2D auto-resizing bitmaps

Apparently the default behavior with Direct2D when rendering is to scale everything I render based on the size of the render target/window. How can I prevent this? I want to decide for myself when to scale the image, regardless of the size of the window.

Hope I am clear enough, and if you need code let me know.

Calling RenderTarget->Resize() is not preventing scaling as MSDN suggests.

I think I posted this on the wrong board but I can't move or delete it...
