Is there any api available to convert an SVG file to an Image(PNG, JPEG, etc.) ?

[Venugopal V]

Hi Lukas,

Is it possible to convert an SVG to an image ?

Are there any existing apis/services or can we tweak existing library to generate images out of svg ?

Thanks,

Venu.

Hi Venu,

you can use batik (http://xmlgraphics.apache.org/batik/) to convert SVG to (any) other formats at the server side.

Hi Venu,

I think this is possible, at least on modern browsers (FF4+, Chrome,
Opera), if you use the fact that <img> can use SVG as their sources on
these browsers.

There are no built-in APIs for this in lib-gwt-svg yet, but if you
combine OMSVGElement.getMarkup() (which gives you a serialized XML
version of your SVG element), data urls, and img, this works (at least
on FF where I have tested it).

This is what it would look like:

public class ExportToImage implements EntryPoint {
public void run() {
OMSVGDocument document = OMSVGParser.currentDocument();
OMSVGSVGElement svg = document.createSVGSVGElement();
svg.getStyle().setWidth(300, Unit.PX);
svg.getStyle().setHeight(300, Unit.PX);
OMSVGCircleElement circle = document.createSVGCircleElement(150,150,120);
circle.getStyle().setSVGProperty("fill", SVGConstants.CSS_YELLOW_VALUE);
circle.getStyle().setSVGProperty("stroke", SVGConstants.CSS_BLACK_VALUE);
svg.appendChild(circle);
String url = "data:image/svg+xml;base64," + base64encode(svg.getMarkup());
Image img = new Image(url);
RootPanel.get().add(new SVGImage(svg));
RootPanel.get().add(img);
}
private static native String base64encode(String str) /*-{
return $wnd.btoa(str);
}-*/;

@Override
public void onModuleLoad() {
run();
}
}

Cheers

Lukas

Thanks Weihua! Batik seems to be viable server side options.

Thank a lot Lukas! Let me try this option and see if it works on Chrome as well.
