RE: Converting from png to bmp

Question

Hi All
I'm using JAI to convert an image given to me from png to a bmp. However I keep getting
: Error: One factory fails for the operation "encode" and a huge list of areas where various errors have occured. It basically results in an empty bmp being written. Here's the code I'm using:
import javax.media.jai.JAI;
import javax.media.jai.RenderedOp;
import java.awt.image.RenderedImage;
import java.io.*;
public class PngToBmp
    private static void convPng(File theFile)
         String name = ((theFile.getName()).replace('.','_'))+".bmp";  //Setting bmp name
         RenderedImage pngImage = JAI.create("fileload", theFile.getPath());  //This is reading in the image
         RenderedOp op =  JAI.create("filestore", pngImage, "C:\\"+name, "BMP"); //This writes the image to the local disk
//This third line of code that is causing the problems - according to the errors produced.
}       I also have a main method in the class to call convPng. Any ideas as to what I've done wrong? I looked at the reading in and writing out website for JAI - that's where I constructed this code from. I've clearly not understood something though.
Thanks for any help in advance.

As no one replied I finally found the solution. I can't really explain why that code posted above doesn't work I guess it has something to do with the way the png is decoded. Anyway if you want to convert a png to a bmp here's the code to do it:
    public static void convPng(String source, String path)
        try
            OutputStream out = new FileOutputStream(path);
            RenderedOp image;
            image = JAI.create("fileload", source);
            image.getMaxX();
            JAI.create("encode", image, out, "bmp", null);
            out.close();
        catch(IOException err)
            System.out.println("!! Read/Encode Error !!");
    }The source string is the path of the png and path is where the bmp is to be saved out to.
