      • getBounds

        java.awt.Rectangle getBounds()
        Returns the bounds of the current image. This should be 'in sync' with getMinX, getMinY, getWidth, getHeight
      • getDependencyRegion

        java.awt.Shape getDependencyRegion​(int srcIndex,
                                           java.awt.Rectangle outputRgn)
        Returns the region of input data is is required to generate outputRgn.
        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.
      • getDirtyRegion

        java.awt.Shape getDirtyRegion​(int srcIndex,
                                      java.awt.Rectangle inputRgn)
        This calculates the region of output that is affected by a change in a region of input.
        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.
