How to use viewBox property for SVG

[Jeroen de Zwart <fa...@dds.nl>]

Thanks to Aaron for writing this very usefull code for providing the viewBox
attribute,

But with me it's not working. The code in PDFRenderer.java:

590    SVGSVGElement svg = area.getSVGDocument().getRootElement();
591    int w = (int)(svg.getWidth().getBaseVal().getValue() * 1000);
592    int h = (int)(svg.getHeight().getBaseVal().getValue() * 1000);

finds values for w and h but

597    if (svg.getViewBox () != null) {

is always null so nothing happens! please tell me what is wrong.

this is the fo i use with the latest (16feb) FOP 0.17 DEV:

<svg:svg width="100mm" height="50mm" viewBox="0 0 1500 1000">
<svg:rect x="0" y="0" width="1500" height="1000" style="fill:yellow" />
<svg:path style="fill:red" d="M 750,100 L 250,900 L 1250,900 z"/>
</svg:svg>
