Examples of org.xhtmlrenderer.simple.Graphics2DRenderer

org.xhtmlrenderer.simple.Graphics2DRenderer
Graphics2DRenderer supports headless rendering of XHTML documents, and is useful for rendering documents directly to images.

Graphics2DRenderer supports the {@link XHTMLPanel#setDocument(Document)}, {@link XHTMLPanel#layout()}, and {@link XHTMLPanel#render()} methods from{@link XHTMLPanel}, as well as easy-to-use static utility methods. For example, to render a document in an image that is 600 pixels wide use the {@link #renderToImageAutoSize(String,int,int)} method like this:
```
 BufferedImage img = Graphics2DRenderer.renderToImage( "test.xhtml", width); 
```
