Class SimpleDataRenderer

java.lang.Object

net.sf.jasperreports.renderers.AbstractRenderer

net.sf.jasperreports.renderers.SimpleDataRenderer

All Implemented Interfaces:

Serializable, AreaHyperlinksRenderable, DataRenderable, Renderable

public class SimpleDataRenderer
extends AbstractRenderer
implements DataRenderable, AreaHyperlinksRenderable

The is a default implementation for the DataRenderable interface that wraps images that come from files or binary image data in JPG, GIF, or PNG format. It can also wrap SVG data, but for better quality when converting to image, the SimpleRenderToImageAwareDataRenderer implementation is recommended.
