[reportlab-users] Canvas background

[Harry Waye]

Hello,

I'm trying to merge (using pyPdf) a template pdf with a pdf generated
from rml with trml2pdf.  The rml generated pdf appears to have a white
background, thus obscures the template pdf on merging.  I would like it
to be transparent.  

Is this something that can be specified in rml?  Is there any way I can
import the template pdf on generation?  I noticed there was an include
pdf tag in the rml user guide, but I get the feeling that it places the
included pdf on top.  Is there anything else I can do?

Is placing a background colour on the pdf an attempt to stop me doing
such things, and to push be to PageCatcher?  ;-)

Cheers,
Harry
