Examples of org.xhtmlrenderer.swing.Java2DRenderer

org.xhtmlrenderer.swing.Java2DRenderer
Renders an XML files, formatted with CSS, as an image. Input is a document in the form of file or URL, and output is a BufferedImage. A Java2DRenderer is not intended to be re-used for multiple document sources; just create new Java2DRenderers for each one you need. Java2DRenderer is not thread-safe. Standard usage pattern is
```
 File xhtml = ... Java2DRenderer rend = new Java2DRenderer(xhtml); BufferedImage image = rend.getImage(); 
```
The document is not loaded, and layout and render don't take place, until {@link #getImage(int)} is called.Subsequent calls to {@link #getImage()} don't result in a reload; create a new Java2DRenderer instance to do so.
As with {@link org.xhtmlrenderer.swing.RootPanel}, you can access the {@link org.xhtmlrenderer.layout.SharedContext} instance that will be used by this renderer and change settingsto control the rendering process; use {@link #getSharedContext()}.

By default, this renderer will render to an RGB image which does not support transparency. To use another type of BufferedImage, either set the image type using {@link #setBufferedImageType(int)} before calling{@link #getImage()}, or else override the {@link #createBufferedImage(int,int)} to have full control overthe image we render to.

Not thread-safe.
