public MorphologyOp(int radiusX,
            int radiusY,
            boolean doDilation)
```
    Parameters:
    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.

                                   java.awt.image.WritableRaster dest)
```
    Filters src and writes result into dest. If dest if null, then a Raster is created. If dest and src refer to the same object, then the source is modified.
    The filtering kernel(the operation range for each pixel) is a rectangle of width 2*radiusX+1 and height radiusY+1
    
    Specified by:
    
    filter in interface java.awt.image.RasterOp
    
    Parameters:
    src - the Raster to be filtered
    dest - 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.
  - filter
```
public java.awt.image.BufferedImage filter(java.awt.image.BufferedImage src,
                                  java.awt.image.BufferedImage dest)
```
    This implementation of filter does the morphology operation on a premultiplied alpha image. This tends to muddy the colors. so something that is supposed to be a mostly transparent bright red may well become a muddy opaque red. Where as I think it should become a bright opaque red. Which is the result you would get if you were using unpremult data.
