public class BufferedDynamicImageResource

extends DynamicImageResource

A DynamicImageResource subclass that holds a BufferedImage generated by code elsewhere. The image is held in a non-transient field, and so if this resource is clustered, the entire image will be serialized and copied. If you can regenerate your image by drawing on a Graphics2D, you should prefer the RenderedDynamicImageResource class instead since its image data is transient and therefore it is very lightweight when clustered.

The extension/format of the image resource can be specified with setFormat(String).

Method Detail

setImage

public void setImage(java.awt.image.BufferedImage image)

Parameters:

image - The image to set

getImageData

protected byte[] getImageData()

Description copied from class: DynamicImageResource

Get image data for our dynamic image resource. If the subclass regenerates the data, it should set the lastModifiedTime when it does so. This ensures that image caching works correctly.

Specified by:

getImageData in class DynamicImageResource

Returns:

The image data for this dynamic image
