Interface DiffuseLightingRable

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.

Method Detail

getKd

public double getKd()

Returns: diffuse constant, or kd.

getKernelUnitLength

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

getLight

public Light getLight()

Returns: Light object used for the diffuse lighting

getLitRegion

public Rectangle2D getLitRegion()

Returns: the litRegion for this filter

getSource

public Filter getSource()
Returns the source to be filtered

getSurfaceScale

public double getSurfaceScale()

Returns: surfaceScale

setKd

public void setKd(double kd)
Sets the diffuse constant, or kd

setKernelUnitLength

public void setKernelUnitLength(double[] kernelUnitLength)
Sets the min [dx,dy] distance in user space for evaluation of the sobel gradient. If set to zero or null then device space will be used.

setLight

public void setLight(Light light)

Parameters: light New Light object

setLitRegion

public void setLitRegion(Rectangle2D litRegion)
Sets the litRegion for this filter

setSource

public void setSource(Filter src)
Sets the source to be filtered

setSurfaceScale

public void setSurfaceScale(double surfaceScale)
Sets the surface scale
