Hi all,
I'm having trying to use iText (v5.2) & the XMLWorker (v1.1.2) tool to
generate a PDF. Trouble is that the resulting PDF doesn't appear to be
using any of the CSS styles defined on the page. Images are there but
no CSS. I've followed the XMLWorker documentation from
http://demo.itextsupport.com/xmlworker/itextdoc/flatsite.html but it's
looking out of date with the current version. The main problem at the
moment at the moment is this line in the documentation:
HtmlPipelineContext htmlContext = new HtmlPipelineContext();
With the versions I am using, the constructor of HtmlPipelineContext
requires a CssAppliers class. I'm supplying a null object for now as I
have no idea how to get my hands on a CssAppliers class but could this
be what is causing my PDF to come out with no CSS styles applied? Does
anyone have any idea how I get my hands on a CssAppliers instance? The
API docs didn't shed much light on the situation.
Can anyone help me get past this step? I've attempted to attach my test
class so you can see what I'm trying to do. No idea how attachments
work with this mailing list though...
Regards,
Lee
