Plot.getProcessor() vs. profile plot preferences

Plot.getprocessor() returns an ImageProcessor that has different dimensions from those defined in the profile plot preferences pp.with and pp.height. Is this intentional?

The test plugin below writes the following to my log:

Plot ImageProcessor:
    getWith()=478
    getHeight()=455
Plot Options:
    pp.width=400
    pp.height=400

TEST PLUGIN:

import ij.*;
import ij.process.*;
import ij.gui.*;
import ij.plugin.*;
import ij.plugin.frame.*;

public class Test_Plot_PixelSize implements PlugIn {

                public void run(String arg) {

                                float[] Xval = new float[1];
                                float[] Yval = new float[1];

                                Plot p = new Plot( "Test Plot PixelSize", "X", "Y", Xval, Yval);
                                ImageProcessor ip = p.getProcessor();

                                IJ.log(
                                                "\nPlot ImageProcessor:\n    getWith()="+ip.getWidth()+
                                                "\n    getHeight()="+ip.getHeight()+
                                                "\n \nPlot Options:\n    pp.width="+Prefs.getInt("pp.width",1)+
                                                "\n    pp.height="+Prefs.getInt("pp.height",1)
                                );

                }

}
