RE: Ideas needed: insert byte[] into XSLFO

Hi,

You can use a data uri or use a custom resource resolver.

FopFactoryBuilder builder = new FopFactoryBuilder(new File(".").toURI(), resolver);
fopFactory = builder.build();

Thanks

Subject: Ideas needed: insert byte[] into XSLFO



Hi all,

I have a byte[] (basically, a PNG or JPG image) that I generated myself and would like to insert it in an XSLFO page at a certain position and render the page to PDF with fop.

Think of it like a letter with a logo, only that the logo is dynamically created.

The best way to insert it seems to be fo:external-graphic, but that requires a url, from where the resource is acquired.

I don't want to save my image to disk or put it on a webserver, so my idea is to somehow make a custom URIResolver, which would supply my generated image(s).

My question is how do I wire this up into my existing fop workflow, which looks like this:

FOUserAgent userAgent = fopFactory.newFOUserAgent(); Fop fop = fopFactory.newFop(mimeType, userAgent, outStream); Result res = new SAXResult(fop.getDefaultHandler());
xslTransformer.transform(xmlSource, res); return outStream.toByteArray()

There appears to be no way to set a custom resolver. Or perhaps someone has a better idea than to do it via custom URI schemes?

Many thanks for any pointers,

Ulrich
