Trying to understand differences between javafx.scene.image, awt.image, BufferedImage, RenderedImage, Raster, PlanarImage

Question

I am new and learning Java (more as a hobby). I am trying to write a program to display TIFs in JavaFX. I understand TIFs are not part of the basic Java-8 JRE/JDK and JAI needs to be used.

First, it looks like I lack the understanding between the different classes of images, JavaFX Image, AWT Image, BufferedImage, RenderedImage, Raster, PlanarImage, etc.

I think once I can wrap my head around those differences, I can better understand the image processing module.

I was finally able to piece together some code based on examples found. (I love the Java community because it always looks like someone has had a similar issue and someone else has resolved it).

I am able to use the JAI to decode a TIFF as a ByteArraySeekableStream into a RenderedImage and use SwingFXUtils to convert to a JavaFX image.

Issue: The file I am trying to process is 50-M. I kept receiving a java.lang.reflect.InvocationTargetException and not understanding why! (still learning).

It wasn't until I processed a 30-kB TIFF that actually displayed the processed image, that I realized the java.lang.reflect.InvocationTargetException was due to java.lang.OutOfMemoryError: Java heap space.

Is there a better memory managed way to process these large TIF files?

static Image load(byte[] inData) throws Exception {
        Image image = null;

        SeekableStream inStream = new ByteArraySeekableStream(inData);

        ImageDecoder dec
                = ImageCodec.createImageDecoder("tiff", inStream, null);

        System.out.println(dec.getInputStream());        

        RenderedImage im = dec.decodeAsRenderedImage();
        image = SwingFXUtils.toFXImage(PlanarImage.wrapRenderedImage(im).getAsBufferedImage(),null);

        return image;
}

@Override
public void start(Stage primaryStage) throws Exception {
    String path = "charts\\DTW_sectional\\Detroit SEC 98.tif";
    //String path = "charts\\javafx-documentation.tif";

    FileInputStream in = new FileInputStream(path);
    FileChannel channel = in.getChannel();
    ByteBuffer buffer = ByteBuffer.allocate((int) channel.size());
    channel.read(buffer);

    // create JavaFX image and load into an ImageView
    Image image = load(buffer.array());
    System.out.println("Path: " + path + "\nImage: "
            + image + "\n");
    ImageView imageView = new ImageView(image);

    //Creating a Group object  
    Group root = new Group(imageView);

    //Creating a scene object 
    Scene scene = new Scene(root, 600, 500);

    //Setting title to the Stage 
    primaryStage.setTitle("Loading an image");

    //Adding scene to the stage 
    primaryStage.setScene(scene);

    //Displaying the contents of the stage 
    primaryStage.show();
