error encountered when writing image file

[angelinehelena]

I'm new to JAI. I want to save a PlanarImage into a JPEG file. I used the following code. But i encounter a NullPointerException while executing.

PlanarImage pi=(PlanarImage)JAI.create("fileload","f1.jpg");
File f=new File("f2.jpg");
FileOutputStream out=new FileOutputStream(f);
JPEGEncodeParam p=new JPEGEncodeParam();
p.setQuality(0.1F);
ImageEncoder e=ImageCodec.createImageEncoder("jpg",out,p);
e.encode(pi);
out.close();


Can anyone help me find the error? Is there anyother solution available?

it would be good if you write exactly on which line to you ger the error
and write the error details too
