Hi,

I'm using the following code, copied off the internet, to translate a
TIF file to JPEG format.  It works, but runs out of memory on one of my
machines.  I can "solve" that by giving Java more memory at launch, but
this is running in a context where I don't have easy access to those
parameters, so I would prefer to reduce the memory requirements for the
function.  I'm still reading up on JAI and it's a lot to take in at one
time; I'd appreciate any pointers to more memory-efficient ways to go
about this.  Thanks!

Peace,
--Carl

 public static void main(String[] args) {
   final String path = "//images//sample";
     RenderedImage image = JAI.create("fileload", path + ".tif");
     WritableRaster raster = image.copyData(null);
     writeJpegFile(path + ".jpg", image, raster);
 }

 private static void writeJpegFile(
     String filename,
     RenderedImage image,
     WritableRaster raster) {
   BufferedImage bi = new BufferedImage(
       image.getColorModel(),
       raster,
       true,
       null);

   BufferedImage bi2 = new BufferedImage(
       bi.getWidth(),
       bi.getHeight(),
       BufferedImage.TYPE_BYTE_GRAY);

   Graphics2D g2 = bi2.createGraphics();
   g2.drawImage(bi, 0, 0, null);
       PlanarImage pi = PlanarImage.wrapRenderedImage(bi2);
       JAI.create(
         "FileStore",
          pi,
          filename,
          "JPEG",
          new JPEGEncodeParam());
 }
