public interface DiffuseLightingRable extends FilterColorInterpolation
This filter primitive lights an image using the alpha channel as a bump map. The resulting image is an RGBA opaque image based on the light color with alpha = 1.0 everywhere. The lighting calculation follows the standard diffuse component of the Phong lighting model. The resulting image depends on the light color, light position and surface geometry of the input bump map. This filter follows the specification of the feDiffuseLighting filter in the SVG 1.0 specification.- Version:

getKernelUnitLength
double[] getKernelUnitLength()
Returns the min [dx,dy] distance in user space for evalutation of the sobel gradient.
