* A {@code (String, Image)} pair that links together a reference ID and
* the source image.
This is used internally by {@link SVGGraphics2D} to track
* images as they are rendered.
This is important when images are not embedded
* in the SVG output, in which case you may need to generate corresponding
* image files for the images (see also {@link SVGGraphics2D#getSVGImages()}).

public final class ImageElement {

/** The filename specified in the href. */
private String href;

/** The image. */
private Image image;

* Creates a new instance.

* @param href
the href ({@code null} not permitted).
* @param image
the image ({@code null} not permitted).

public ImageElement(String href, Image image) {
Args.nullNotPermitted(href, "href");
Args.nullNotPermitted(image, "image");
this.href = href;
this.image = image;

* Returns the reference ID that was specified in the constructor.

* @return The href (never {@code null}).

public String getHref() {
return href;

* Returns the image that was specified in the constructor.

* @return The image (never {@code null}).

public Image getImage() {
return image;

* Returns a string representation of this object, primarily for debugging
* purposes.

* @return A string.
