createRendering

public java.awt.image.RenderedImage createRendering(java.awt.image.renderable.RenderContext rc)

Specified by:

createRendering in interface java.awt.image.renderable.RenderableImage

getDependencyRegion

public java.awt.Shape getDependencyRegion(int srcIndex,
                                          java.awt.geom.Rectangle2D outputRgn)

Returns the region of input data is is required to generate outputRgn.

Specified by:

getDependencyRegion in interface Filter

Overrides:

getDependencyRegion in class AbstractRable

Parameters:

srcIndex - The source to do the dependency calculation for.

outputRgn - The region of output you are interested in generating dependencies for. The is given in the user coordiate system for this node.

Returns:

The region of input required. This is in the user coordinate system for the source indicated by srcIndex.

getDirtyRegion

public java.awt.Shape getDirtyRegion(int srcIndex,
                                     java.awt.geom.Rectangle2D inputRgn)

This calculates the region of output that is affected by a change in a region of input.

Specified by:

getDirtyRegion in interface Filter

Overrides:

getDirtyRegion in class AbstractRable

Parameters:

srcIndex - The input that inputRgn reflects changes in.

inputRgn - the region of input that has changed, used to calculate the returned shape. This is given in the user coordinate system of the source indicated by srcIndex.

Returns:

The region of output that would be invalid given a change to inputRgn of the source selected by srcIndex. this is in the user coordinate system of this node.
