Identifiers for properties of the Point-specular lighting effect.
The light position of the point light source. The property is a D2D1_VECTOR_3F defined as (x, y, z). The units are in device-independent pixels (DIPs) and the values are unitless and unbounded.
The type is D2D1_VECTOR_3F.
The default value is {0.0f, 0.0f, 0.0f}.
The exponent for the specular term in the Phong lighting equation. A larger value corresponds to a more reflective surface. This value is unitless and must be between 1.0 and 128.
The type is FLOAT.
The default value is 1.0f.
The ratio of specular reflection to the incoming light. The value is unitless and must be between 0 and 10,000.
The type is FLOAT.
The default value is 1.0f.
The scale factor in the Z direction for generating a height map. The value is unitless and must be between 0 and 10,000.
The type is FLOAT.
The default value is 1.0f.
The color of the incoming light. This property is exposed as a D2D1_VECTOR_3F – (R, G, B) and used to compute LR, LG, LB.
The type is D2D1_VECTOR_3F.
The default value is {1.0f, 1.0f, 1.0f}.
The size of an element in the Sobel kernel used to generate the surface normal in the X and Y directions. This property maps to the dx and dy values in the Sobel gradient. This property is a D2D1_VECTOR_2F(Kernel Unit Length X, Kernel Unit Length Y) and is defined in (DIPs/Kernel Unit). The effect uses bilinear interpolation to scale the bitmap to match size of kernel elements.
The type is D2D1_VECTOR_2F.
The default value is {1.0f, 1.0f}.
The interpolation mode the effect uses to scale the image to the corresponding kernel unit length. There are six scale modes that range in quality and speed.
The type is D2D1_POINTSPECULAR_SCALE_MODE.
The default value is D2D1_POINTSPECULAR_SCALE_MODE_LINEAR.
