D3DImage using DX10

Question

Is it possible to use DirectX 10 (I am using SlimDX) with WPF\'s D3DImage? The only examples and docs I can find only show using DX9 surfaces.

Answer 1

Yes, you can use DirectX 10, 11, and DirectWrite using the D3DImage in WPF by creating your render target surface as shared, and then creating a DX9 texture based on that shared texture handle to use in WPF.

This means that essentially you can use 10, 11, and DirectWrite the same way you use DX9 with no additional overhead, and no airspace issues.

A sample WPF project with DX9, DX10, DX11, and DirectWrite integration can be found referenced in this blog post here:

The Microsoft Code Pack contains a thin managed wrapper for Windows 7 components including DX9, DX10, DX11 and DirectWrite in addition to various other unmanaged libraries in Windows 7.

The SurfaceQueueInteropHelper is a WPF control that manages automatically creating DX9, 10, and 11 contexts in WPF and managing D3DImage updating and various other aspects of the rendering system including device lost events.
