jfor : XSL-FO to RTF converter

Hello,

I'm trying to insert an image in background of first
page of the rtf document with JFOR 7.0.
Transformation fo to rtf

What I need is the put an image and write sone text
over the image.

First try :
The dot model has the background image on the first
page. All styles are inside the rtf document, but the
image inserted in the dot model, has not rendrered
into the rft document.
FAILED.

Second try :
Insert the image on first page and after, insert a
<fo:block space-before="-5in"> to write text.
Jfor does not accept.
FAILED.

If anyone has an idea to tell me...

Thanks
