Properties

Properties

The SVGFESpecularLightingElement object has these properties.

Property	Access type	Description
height		Gets or sets the height of an element.
in1	Read-only	Identifies input for the given filter primitive.
kernelUnitLengthX	Read-only	`kernelUnitLength` indicates the intended distance in current filter units for dx and dy in the surface normal calculation formulas.
kernelUnitLengthY	Read-only	`kernelUnitLength` indicates the intended distance in current filter units for dx and dy in the surface normal calculation formulas.
result	Read-only	Provides a reference for the output result of a filter.
specularConstant	Read-only	Specifies the diffuse refection constant used to calculate the effects of diffusion and reflection from a light source.
surfaceScale	Read-only	Specifies surface height when the alpha channel of the input image is set to 100% opacity.
width		Defines the width of an element.
x		Gets or sets the x-coordinate value.
y		Gets or sets the y-coordinate value.

Remarks

The resulting image is an RGBA image based on the light color. The lighting calculation follows the standard specular component of the Phong lighting model. The resulting image depends on the light color, light position, and surface geometry of the input bump map.
