Embedding SVG in XSLT (XSL-FO)

Hi there Gurus!

I wonder if you can help me out here...

I have a XSL-FO document that describes how my document should be rendered when printing it to PDF format. I have a <fo:block> elemnt with some text that i want to rotate. Now, i know that this is achievable using <reference-orientation>, but in my case it wont do, because my FOP version does not support this element. I found a solution in WEB, that shows how i can do the rotation using SVG. But the problem is that when i run my app(written in C#) i get error that says that some SVG elements are not supportable. I think that it should somehow be related with my declaration of the SVG in XSL-FO.
Code:

Code:

<fo:block>
      <fo:instream-foreign-object>
        <svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" width="25pt" height="25pt">
          <g x="5px" y="5px" transform="rotate(45)" style="stroke:none; fill:#000000;">Text</g>
        </svg>
      </fo:instream-foreign-object>
    </fo:block>

and the error i get is:

Code:

Unsupported element encountered: svg (Namespace: http://www.w3.org/2000/svg). Source context: Unknown source

Expected XSL-FO (root, page-sequence, etc.), SVG (svg, rect, etc.) or elements from anothersupported language.

Unsupported element encountered: g (Namespace: http://www.w3.org/2000/svg). Source context: Unknown source

Anybody got an idea what could be wrong?!?

Thanks in advance.

As far as I know, you are not allowed to put plain text into an SVG "g" element, you need to put some allowed element in there, like "text" or "tspan".

Thanks for your quick reply, but yeah, i've tried <text> before with no luck...

Sounds like an issue with the particular XSL-FO processor you are using. I would recommend checking with them (and you don't mention what processor/library you are using - C# does not have a built in one).

I think you might want to look for a forum dedicated to the FOP processor you use to find out whether it supports SVG at all and if so how you use it.

The library i use is nFop and vjslib.

Thanks guys anyway. I'll keep on searching...

Martin, you were right...
My nFop does not support SVG, well actually it does, but just a little. I shall rethink my project needs.

Thank you guys for trying to help me.
