Class RenderedImageCachableRed

java.lang.Object
  org.apache.xmlgraphics.image.rendered.RenderedImageCachableRed

All Implemented Interfaces:

CachableRed, java.awt.image.RenderedImage

public class RenderedImageCachableRed

extends java.lang.Object

implements CachableRed

This implements CachableRed around a RenderedImage. You can use this to wrap a RenderedImage that you want to appear as a CachableRed. It essentially ignores the dependency and dirty region methods.

                                          java.awt.Rectangle outputRgn)

Description copied from interface: CachableRed

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

Specified by:

getDependencyRegion in interface CachableRed

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 output pixel coordiate system for this node.

Returns:

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

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

Specified by:

getDirtyRegion in interface CachableRed

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 pixel 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 output pixel coordinate system of this node.
