Png output and transparent background

[Peter <pc...@gmail.com>]

FOP Fans,

 

I am (a beginning fop user) using fop with png output (tried both the trunk
and 0.92 beta) and was wondering whether there is a possibility to set the
page background to transparent.

 

I tried background-color="transparent" but that does not seem to work.

 

Any guidance would be greatly appreciated,

 

Thanks,

 

Peter

I've added in my project images as GIF with transparency.

It all goes well in the PDF, but the "transparency" in the image of the
final object is only apparent, as it will only render in the PDF. If i get
it to any RIP software to produce offset plates, the "transparency" goes on
hollidays and the background is in white.

(my guess is that in the process, the transparent color is placed somewhere
where the pdf gets it and interprets it, but the RIP software doesn't look
at it (ie. it is for instance marked on the "document" but discarded in the
image by itself)
