    <p>The javascript mode of Processing utilizes HTML5 Canvas by default for rendering. You can use the HTML5 toDataURL method of canvas in order to export a PNG. </p> <p><a href="https://developer.mozilla.org/en-US/docs/Web/API/HTMLCanvasElement" rel="nofollow noreferrer">https://developer.mozilla.org/en-US/docs/Web/API/HTMLCanvasElement</a></p> <p>In fact, that is what <a href="http://processingjs.org/reference/save_/" rel="nofollow noreferrer">save()</a> and <a href="http://processingjs.org/reference/saveFrame_/" rel="nofollow noreferrer">saveFrame()</a> do in Processing.js. If you look throug the reference in <a href="http://processingjs.org/reference/" rel="nofollow noreferrer">Processing.js</a> you'll notice that the functions you would use to export PDF in Processing are unavailable (indicated by red). </p> <p>Exporting to PDF from canvas does not seem possible. However, there are a few <a href="http://fabricjs.com/" rel="nofollow noreferrer">frameworks</a> that export canvas to SVG. It has been <a href="https://stackoverflow.com/questions/9648878/exporting-vector-graphics-from-html5-canvas">asked here before</a> as well. </p> <p><a href="http://coding.smashingmagazine.com/2012/02/22/web-drawing-throwdown-paper-processing-raphael/" rel="nofollow noreferrer">Here</a> is an extensive study for going from SVG to canvas and back again. Towards the bottom there is an excellent roundup of toolkits you can use. However, mixing these in with Processing.js is non-trivial. </p> <p>If you don't know Javascript well and you need to export to PDF or SVG in Javascript and not Java then I would suggest one of these other toolkits. Here is a <a href="http://coding.smashingmagazine.com/2012/02/22/web-drawing-throwdown-paper-processing-raphael/" rel="nofollow noreferrer">great page</a> that shows the basics of getting started on Processing.js vs Paper.js vs Raphael. You'll notice that is isn't too different, if you know Processing then you should be ok.</p> <p>Processing.js can also render to <a href="http://processingjs.org/articles/RenderingModes.html" rel="nofollow noreferrer">WebGL</a> but that doesn't have either an SVG or PDF export option natively or through any toolkit that I know of. </p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
