Hi Knut, Thanks for info. Will take a look. If I can find a solution, I'll post it for your info.

I research it some weeks ago and have found no solution. Donno if somthing have changed. I suggest to research in the FOP List Archiv: http://nagoya.apache.org/eyebrowse/SearchList?listId=&listName=fop-user@xml. apache.org&searchText=PNG+Transparent+Images&defaultField=body&Search=Search Some Posts ago Antenna House announce a new beta Version that seems to support transparent images: http://www.antennahouse.com/XSL30/V31newfeatureEN.htm best regards, BRAINFRUIT GmbH Knut Meinke Neue Adresse!

It's not that I can't render any image or indeed a png image. I can render most types of images, including png. The problem (and I apologise if I did not explain it adequately) is that I have a png image which is transparent. This image sits on top of a grey background. Both image and background are created in block-containers in region-before. The image background is white and it is this colour which is selected as the transparent colour for the png. Accordingly, when rendered, I was hoping that the png's white background would be transparent and that the grey background would show through the transparent sections of the png. It doesn't. The background of the image is a whote square sitting on top of the grey background. I don't know if this is an xsl problem or a fop problem. What I am first trying to establish is what should be the default xsl behaviour for a transparent png in this context. Should the grey background underneath show through the transparent sections of the png? If the default behaviour doesn't help me, is there some attribute I need to set (eg Transparent) which will give me what I need. Thanks for any help you can give.
