- All Known Implementing Classes:
DiffuseLightingRable8Bit
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.
