	Queries a COM object for a pointer to one of its interface; identifying the interface by a reference to its interface identifier (IID). If the COM object implements the interface, then it returns a pointer to that interface after calling IUnknown::AddRef on it.

Member Function Documentation

◆ GetPatchCount()

UINT32 Harlinn::Windows::Graphics::GradientMesh::GetPatchCount ( ) const

inline

Returns the number of patches of the gradient mesh.

Returns: Returns the number of patches that make up this gradient mesh.
