Hello Shin-ta,

Like Bill, I'm not sure why you are seeing the TYPE_USHORT_565_RGB.
If it helps, here is some code that Ugo Taddei sent me for saving
a display to a JPEG format.  The com.sun.image.codec.jpeg included
in Java 2 has classes for encoding and decoding JPEG images.  You
could always convert the JPEG to GIF if you needed to.

Hi Don,

not quite what you wanted, but the following fragment will save a
display to a file, using a JfileChooser 

      try{
            
            JFileChooser fc= new JFileChooser();
            fc.setDialogTitle("Save screenshot as Jpeg");
            fc.setCurrentDirectory(new File(curDir) );
            if(fc.showDialog(cframe, "Save") == JFileChooser.APPROVE_OPTION) {
              System.out.println("Saving image..." );
            String cfn = fc.getSelectedFile().getName(); 
            curDir = fc.getCurrentDirectory().getName(); 
            
            BufferedImage image = display1.getImage();
            FileOutputStream fout = new FileOutputStream(cfn);
            JPEGEncodeParam jepar = JPEGCodec.getDefaultJPEGEncodeParam(image);
            jepar.setQuality( 1.0f, true);
            
            JPEGImageEncoder jpege = JPEGCodec.createJPEGEncoder(fout) ;
            jpege.encode(image, jepar);
            fout.close(); 
            System.out.println("Saved "+cfn);
            } else {
                System.out.println("No file was chosen or an error occurred");
            } 
            
           
            } catch (IOException ioe) { System.err.println(ioe.getMessage() );
            }
        
Hope it helps...

Ugo
