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.java.awt.Shape getDirtyRegion(int srcIndex, java.awt.Rectangle 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 pixel
coordinate system of the source indicated by srcIndex.Copyright © 2022 Apache Software Foundation. All Rights Reserved.
