how to decrease the size of the jpeg image file?

Hi friends i'm using this code for capturing the screen . i want to set the quality of the image . how to do that?


baos = new ByteArrayOutputStream();
com.sun.image.codec.jpeg.JPEGImageEncoder enc = JPEGCodec.createJPEGEncoder( baos ); // encode the image to jpg
enc.encode(BI);
FileOutputStream fos=new FileOutputStream("Screen_Shot_"+count+".jpg");
BufferedOutputStream bos = new BufferedOutputStream( fos );
byte[] b = baos.toByteArray();
bos.write( b );
bos.flush();
bos.close();

You can use the setQuality method of JPEGEncodeParam. It's documented here.

Hi Ulf Dittmer! Thanks for the help provided by you.

Hi Ulf Dittmer!

I'm having problem. This line of code is raising nullpointer exception "JPEGEncodeParam param = enc.getJPEGEncodeParam();". what might be the problem?

Is "enc" null? If not, post the stack trace.
