Can't convert PNG image to GIF image

                 Key: SANSELAN-5
             Project: Sanselan
          Issue Type: Bug
         Environment: Windows XP SP2, Eclipse IDE, Custom Java database conversion program,
JRE 1.5.x
            Reporter: Dirk Daems
            Assignee: Carsten Ziegeler
            Priority: Blocker

I want to transform a set of PNG images to GIF images.
The code I tried:

private static void convertImage(String sourceDir, String sourceFile, String targetDir){
   BufferedImage source = Sanselan.getBufferedImage(new File(sourceDir + File.separator +
   String targetFile = sourceFile.substring(0, sourceFile.indexOf('.')) + ".gif";
   Hashtable parms = new Hashtable();
   // parms.put(SanselanConstants.PARAM_KEY_VERBOSE, Boolean.TRUE);
   Sanselan.writeImage(source, new File(targetDir + File.separator + targetFile), ImageFormat.IMAGE_FORMAT_GIF,
  catch(Exception ex){
I don't get any errors but the image that's generated cannot be displayed and is way too small
