Shape getDependencyRegion(int srcIndex, Rectangle2D outputRgn)
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.Shape getDirtyRegion(int srcIndex, Rectangle2D inputRgn)
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.Copyright © 2000–2023 Apache Software Foundation. All rights reserved.
