问题
I try to use DirectX ChromaKey effect, but my function stucks on some step.
What I do:
- Create ID2D1Factory1
- Create ID3D11Device and ID3D11DeviceContext
- Obtain DXGIResource from received texture
- Obtain shared handle from DXGIResource
- Open DXGIResource as new ID3D11Texture2D using ID3D11Device
- Obtain D3D11_TEXTURE2D_DESC of new ID3D11Texture2D
- Create new ID3D11Texture2D using input ID3D11Texture2D and D3D11_TEXTURE2D_DESC
- Copy resource from obtained ID3D11Texture2D to created ID3D11Texture2D
- Obtain IDXGISurface from created ID3D11Texture2D
- Define D2D1_SIZE_U, D2D1_PIXEL_FORMAT, D2D1_BITMAP_PROPERTIES
- Obtain desktop DPI from ID2D1Factory1
- Create D2D1_RENDER_TARGET_PROPERTIES using obtained DPI
- Create ID2D1RenderTarget using ID2D1Factory1, IDXGISurface and D2D1_RENDER_TARGET_PROPERTIES
- Create shared ID2D1Bitmap using ID2D1RenderTarget, IDXGISurface and D2D1_BITMAP_PROPERTIES
- Obtain IDXGIDevice using ID3D11Device
- Create ID2D1Device using ID2D1Factory1 and IDXGIDevice
- Obtain ID2D1DeviceContext using ID2D1Device
- Create ChromaKey ID2D1Effect using ID2D1DeviceContext
- Define D2D1_VECTOR_3F basing on ChromaKey background
- Set parameters and D2D1_VECTOR_3F of ID2D1Effect
- Drow over ID2D1Bitmap using ID2D1DeviceContext, and ID2D1Effect
- Return new ID3D11Texture2D bound to ID2D1Bitmap
Here is a code.

#define SIZEOF_ARRAY(arr) (sizeof(arr)/sizeof((arr)[0]))
#define RET_HR(_f) hr = _f; if (FAILED(hr)) return hr;
#define RET_HR_NULL( _f, _obj ) hr = _f; if (FAILED(hr) || !_obj) return FAILED(hr) ? hr : S_FALSE;

The input picture:
Now, I'm stucking on 13th step:
- Create ID2D1RenderTarget using ID2D1Factory1, IDXGISurface and D2D1_RENDER_TARGET_PROPERTIES
RET_HR_NULL(cpD2DFactory->CreateDxgiSurfaceRenderTarget(
cpDXGISurface,
&d2d1RenderTargetProperties,
&cpRenderTarget),
cpRenderTarget);
Despite D3D11_CREATE_DEVICE_DEBUG I get just follow error as HRESULT of CreateDxgiSurfaceRenderTarget:
E_INVALIDARG One or more arguments are invalid.
