Chris:

Looks pretty good.  I did a similar one that I use with my web cam to
scale the image.

import java.awt.*;
import java.awt.geom.*;
import java.awt.image.*;
import java.io.*;
import javax.imageio.*;

public class ScaleImage2 {
    public static void scale(String srcFile, int destWidth, int destHeight,
     String destFile) throws IOException {
        BufferedImage src = ImageIO.read(new File(srcFile));
        BufferedImage dest =  new BufferedImage(destWidth,destHeight,
         BufferedImage.TYPE_INT_RGB);
        Graphics2D g = dest.createGraphics();
        AffineTransform at = AffineTransform.getScaleInstance(
         (double)destWidth/src.getWidth(),
         (double)destHeight/src.getHeight());
        g.drawRenderedImage(src,at);
        ImageIO.write(dest,"JPG",new File(destFile));
    }

    public static void main(String[] args) {
        if (args.length == 4) {
            try {

scale(args[0],Integer.parseInt(args[1]),Integer.parseInt(args[2]),
                 args[3]);
            } catch (Exception e) {
                System.out.println(e);
            }
        } else
            System.out.println("\nUsage: java -jar ScaleImage2.jar
srcfile " +
             "width height destfile\n");
    }
}
