Interface DiffuseLightingRable

All Superinterfaces:

Filter, FilterColorInterpolation, RenderableImage

All Known Implementing Classes:

DiffuseLightingRable8Bit

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.

getLight

Light getLight()

Returns:

Light object used for the diffuse lighting

setLight

void setLight(Light light)

Parameters:

light - New Light object

getSurfaceScale

double getSurfaceScale()

Returns:

surfaceScale

setSurfaceScale

void setSurfaceScale(double surfaceScale)

Sets the surface scale

getKd

double getKd()

Returns:

diffuse constant, or kd.

setKd

void setKd(double kd)

Sets the diffuse constant, or kd

getLitRegion

Rectangle2D getLitRegion()

Returns:

the litRegion for this filter

setLitRegion

void setLitRegion(Rectangle2D litRegion)

getKernelUnitLength

double[] getKernelUnitLength()

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