Method Summary | |
---|---|
RenderedImage | createRendering(RenderContext rc) |
Rectangle2D | getBounds2D()
Pass-through: returns the source's bounds |
Shape | getDependencyRegion(int srcIndex, Rectangle2D outputRgn)
Returns the region of input data is is required to generate
outputRgn. |
Shape | getDirtyRegion(int srcIndex, Rectangle2D inputRgn)
This calculates the region of output that is affected by a change
in a region of input. |
boolean | getDoDilation()
Returns whether the operation is "dilation" or not("erosion") |
double | getRadiusX()
Returns the radius along the x-axis, in user space. |
double | getRadiusY()
Returns the radius along the y-axis, in user space. |
Filter | getSource()
Returns the source to be offset. |
void | setDoDilation(boolean doDilation)
The switch that determines if the operation
is to "dilate" or "erode". |
void | setRadiusX(double radiusX)
The radius along the x axis, in user space. |
void | setRadiusY(double radiusY)
The radius along the y axis, in user space. |
void | setSource(Filter src)
Sets the source to be offset. |
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.
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.
Parameters: doDilation do "dilation" when true and "erosion" when false
Parameters: radiusX should be greater than zero.
Parameters: radiusY should be greater than zero.
Parameters: src image to offset.
