D2D1_GRADIENT_MESH_PATCH structure (d2d1_3.h)

Represents a tensor patch with 16 control points, 4 corner colors, and boundary flags. An ID2D1GradientMesh is made up of 1 or more gradient mesh patches. Use the GradientMeshPatch function or the GradientMeshPatchFromCoonsPatch function to create one.
