|public abstract class java.awt
Java SE 6
Imageis the superclass of all classes that represent graphical images. The image must be obtained in a platform-specific manner.
|protected float||accelerationPriority Details
Priority for accelerating this image. Subclasses are free to set different default priorities and applications are free to set the priority for specific images via the
|final public static Object||UndefinedProperty|
|final public static int||SCALE_DEFAULT Details
Use the default image-scaling algorithm.
|final public static int||SCALE_FAST Details
Choose an image-scaling algorithm that gives higher priority to scaling speed than smoothness of the scaled image.
|final public static int||SCALE_SMOOTH Details
Choose an image-scaling algorithm that gives higher priority to image smoothness than scaling speed.
|final public static int||SCALE_REPLICATE Details
Use the image scaling algorithm embodied in the
|final public static int||SCALE_AREA_AVERAGING Details
Use the Area Averaging image scaling algorithm. The image object is free to substitute a different filter that performs the same algorithm yet integrates more efficiently into the image infrastructure supplied by the toolkit.
Flushes all reconstructable resources being used by this Image object. This includes any pixel data that is being cached for rendering to the screen as well as any system resources that are being used to store data or pixels for the image if they can be recreated. The image is reset to a state similar to when it was first created so that if it is again rendered, the image data will have to be recreated or fetched again from its source.
Examples of how this method affects specific types of Image object:
|public void||setAccelerationPriority(float priority) Details
Sets a hint for this image about how important acceleration is. This priority hint is used to compare to the priorities of other Image objects when determining how to use scarce acceleration resources such as video memory. When and if it is possible to accelerate this Image, if there are not enough resources available to provide that acceleration but enough can be freed up by de-accelerating some other image of lower priority, then that other Image may be de-accelerated in deference to this one. Images that have the same priority take up resources on a first-come, first-served basis.
|public float||getAccelerationPriority() Details
Returns the current value of the acceleration priority hint.
|public ImageCapabilities||getCapabilities(GraphicsConfiguration gc) Details
Returns an ImageCapabilities object which can be inquired as to the capabilities of this Image on the specified GraphicsConfiguration. This allows programmers to find out more runtime information on the specific Image object that they have created. For example, the user might create a BufferedImage but the system may have no video memory left for creating an image of that size on the given GraphicsConfiguration, so although the object may be acceleratable in general, it is does not have that capability on this GraphicsConfiguration.
|abstract public Graphics||getGraphics() Details
|abstract public int||getHeight(ImageObserver observer) Details
Determines the height of the image. If the height is not yet known, this method returns
|abstract public Object||getProperty(String name, ImageObserver observer) Details
Gets a property of this image by name.
Individual property names are defined by the various image
formats. If a property is not defined for a particular image, this
method returns the
If the properties for this image are not yet known, this method
The property name
|public Image||getScaledInstance(int width, int height, int hints) Details
Creates a scaled version of this image. A new
|abstract public ImageProducer||getSource() Details
Gets the object that produces the pixels for the image. This method is called by the image filtering classes and by methods that perform image conversion and scaling.
|abstract public int||getWidth(ImageObserver observer) Details
Determines the width of the image. If the width is not yet known, this method returns
