      • raster

        protected Raster raster
        The Raster being referenced.
      • thumbnails

        protected List<? extends BufferedImage> thumbnails
        A List of BufferedImage thumbnails, or null. Non-BufferedImage objects must not be stored in this List.

        public IIOImage​(RenderedImage image,
                        List<? extends BufferedImage> thumbnails,
                        IIOMetadata metadata)
        Constructs an IIOImage containing a RenderedImage, and thumbnails and metadata associated with it.

        All parameters are stored by reference.

        The thumbnails argument must either be null or contain only BufferedImage objects.

        Parameters:
        image - a RenderedImage.
        thumbnails - a List of BufferedImages, or null.
        metadata - an IIOMetadata object, or null.
        Throws:
        IllegalArgumentException - if image is null.

        Constructs an IIOImage containing a Raster, and thumbnails and metadata associated with it.

        All parameters are stored by reference.

        Parameters:
        raster - a Raster.

      • hasRaster

        public boolean hasRaster()
        Returns true if this IIOImage stores a Raster rather than a RenderedImage.
        Returns:
        true if a Raster is available.
      • getRaster

        public Raster getRaster()
        Returns the currently set Raster, or null if only a RenderedImage is available.
        Returns:
        a Raster, or null.

      • setRaster

        public void setRaster​(Raster raster)
        Sets the current Raster. The value is stored by reference. Any existing RenderedImage is discarded.
        Parameters:
        raster - a Raster.
        Throws:
        IllegalArgumentException - if raster is null.

      • getNumThumbnails

        public int getNumThumbnails()
        Returns the number of thumbnails stored in this IIOImage.
        Returns:
        the number of thumbnails, as an int.
      • setThumbnails

        public void setThumbnails​(List<? extends BufferedImage> thumbnails)
        Sets the list of thumbnails to a new List of BufferedImages, or to null. The reference to the previous List is discarded.

        The thumbnails argument must either be null or contain only BufferedImage objects.

        Parameters:
        thumbnails - a List of BufferedImage thumbnails, or null.
