```
public class JMFImageToken
extends ImageToken
```
A token that contains a javax.media.Buffer. This token is used when dealing with images in the Java Media Framework (JMF) library. Because it extends ImageToken, it can be used with the standard image processing tools by simply casting it, and calling asAWTImage().

- Constructor Detail
  - JMFImageToken
```
public JMFImageToken(javax.media.Buffer value)
```
    Construct a token with a specified Buffer.
    
    Parameters:
    
    value - The buffer.
- Method Detail
  - asAWTImage
```
public java.awt.Image asAWTImage()
```
    Convert a javax.media.Buffer to a java.awt.Image and return it. A new javax.media.util.BufferToImage is created when the video format of the Buffer changes.
    
    Specified by:
    
    asAWTImage in class ImageToken
    
    Returns:
    
    The image.
  - getType
```
public Type getType()
```
    Return the type of this token.
    
    Overrides:
    
    getType in class ObjectToken
    
    Returns:
    
    BaseType.OBJECT
  - getValue
```
public javax.media.Buffer getValue()
```
    Return the value of this token.
    
    Overrides:
    
    getValue in class ObjectToken
    
    Returns:
    
    The value of this token.
  - toString
```
public java.lang.String toString()
```
    Return a description of the token. If possible, derived classes should override this method and return the value of this token as a string that can be parsed by the expression language to recover a token with the same value. Unfortunately, in this base class, we can only return the a partial description of the token.
    
    Overrides:
    
    toString in class ObjectToken
    
    Returns:
    
    A string representation of a record that partially describes the token.
