# Class ImageIcon

java.lang.Object
javax.swing.ImageIcon

All Implemented Interfaces:
  `Serializable, Accessible, Icon`

public class ImageIcon extends Object implements Icon, Serializable, Accessible
An implementation of the Icon interface that paints Icons from Images. Images that are created from a URL, filename or byte array are preloaded using MediaTracker to monitor the loaded state of the image.

For further information and examples of using image icons, see How to Use Icons in The Java Tutorial.

Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans has been added to the `java.beans` package. Please see `XMLEncoder`.

Since:
  1.2

- ## Constructor Details

  - ### ImageIcon

    public ImageIcon(String filename, String description)
    Creates an ImageIcon from the specified file. The image will be preloaded by using MediaTracker to monitor the loading state of the image.
    Parameters:
      `filename` - the name of the file containing the image
      `description` - a brief textual description of the image
    See Also:
      - `ImageIcon(String)`

  - ### ImageIcon

    @ConstructorProperties("description") public ImageIcon(String filename)
    Creates an ImageIcon from the specified file. The image will be preloaded by using MediaTracker to monitor the loading state of the image. The specified String can be a file name or a file path. When specifying a path, use the Internet-standard forward-slash ("/") as a separator. (The string is converted to an URL, so the forward-slash works on all systems.) For example, specify:

           new ImageIcon("images/myImage.gif")

    The description is initialized to the `filename` string.
    Parameters:
      `filename` - a String specifying a filename or path
    See Also:
      - `getDescription()`

  - ### ImageIcon

    public ImageIcon(URL location, String description)
    Creates an ImageIcon from the specified URL. The image will be preloaded by using MediaTracker to monitor the loaded state of the image.
    Parameters:
      `location` - the URL for the image
      `description` - a brief textual description of the image
    See Also:
      - `ImageIcon(String)`

  - ### ImageIcon

    public ImageIcon(URL location)

    Parameters:
      `location` - the URL for the image
    See Also:
      - `getDescription()`

  - ### ImageIcon

    public ImageIcon(Image image, String description)

      `image` - the image
      `description` - a brief textual description of the image

  - ### ImageIcon

    public ImageIcon(Image image)
    Creates an ImageIcon from an image object. If the image has a "comment" property that is a string, then the string is used as the description of this icon.
    Parameters:
      `image` - the image
    See Also:
      - `getDescription()`
      - `Image.getProperty(String, ImageObserver)`

  - ### ImageIcon

    public ImageIcon(byte[] imageData, String description)
    Creates an ImageIcon from an array of bytes which were read from an image file containing a supported image format, such as GIF, JPEG, or (as of 1.3) PNG. Normally this array is created by reading an image using Class.getResourceAsStream(), but the byte array may also be statically stored in a class.
    Parameters:
      `imageData` - an array of pixels in an image format supported by the AWT Toolkit, such as GIF, JPEG, or (as of 1.3) PNG
      `description` - a brief textual description of the image

If the resulting image has a "comment" property that is a string, then the string is used as the description of this icon.
    Parameters:
      `imageData` - an array of pixels in an image format supported by the AWT Toolkit, such as GIF, JPEG, or (as of 1.3) PNG

      `image` - the image

  - ### getDescription

    public String getDescription()
    Gets the description of the image. This is meant to be a brief textual description of the object. For example, it might be presented to a blind user to give an indication of the purpose of the image. The description may be null.

    Paints the icon. The top-left corner of the icon is drawn at the point (`x`, `y`) in the coordinate space of the graphics context `g`. If this icon has no image observer, this method uses the `c` component as the observer.
    Specified by:
      `paintIcon` in interface `Icon`
    Parameters:
      `c` - the component to be used as the observer if this icon has no image observer

      the height in pixels of this icon

  - ### setImageObserver

    public void setImageObserver(ImageObserver observer)
    Sets the image observer for the image. Set this property if the ImageIcon contains an animated GIF, so the observer is notified to update its display. For example:
