I'm new with Direct2D and exploring its possibilites.

I need to create 64bpp RGBA images. Have been struggling with this for a while now without success.

According to:
WICBitmaps/D2DBitmaps doesn't support such pixelformat. :(

Can anyone confirm this?

The reason i need to do this is because i load and render input images which are 64bpp RGBA 16bits per channel.
So far ive only managed to load and convert them to 32bpp.
I need to load and maintain them in 64bpp and also be able to output as 64bpp images.

Does anyone have any suggestion how i can solve this?

Did some more reading and according to a microsoft whitepaper WIC do support 64bpp PixelFormat.

You can check it out here:
The "High Color in Windows 7" whitepaper.

[font="Verdana, sans-serif"] [/font]But i can't get this to work with Direct2D. That white paper does only mention Direct3D though.
I was hoping someone had experience with this or if someone knows a way around this, maybe using a DirectX Texture and a DXGI RenderTarget to achieve this..
I'm totally new to the DirectX API and i really need all help i can get with this problem.
