public MorphologyOp(int radiusX, int radiusY, boolean doDilation)
radiusX
- defines the radius of filter operation on X-axis. Should not be negative.
A value of zero will disable the effect of the operation on X-axis, as described
in the SVG specification.radiusY
- defines the radius of filter operation on Y-axis. Should not be negative.
A value of zero will disable the effect of the operation on Y-axis, as described
in the SVG specification.doDilation
- defines whether to do dilation or erosion operation. Will do dilation
when the value is true, erosion when false.public java.awt.geom.Rectangle2D getBounds2D(java.awt.image.Raster src)

src
- the Raster to be filtereddest
- stores the filtered image. If null, a destination will
be created. src and dest can refer to the same Raster, in
which situation the src will be modified.public java.awt.image.BufferedImage filter(java.awt.image.BufferedImage src, java.awt.image.BufferedImage dest)
