If
the PDFRenderer centers the image properly and the PCLRenderer does
not then it is probably a bug in FOP (likely the PCLRenderer) not a problem
with the FO code.

"IIRC images", sorry I should have included a comma in there as
in:
"If I remember correctly, images..."
It seems a bit odd to me that the PDF renderer would center the
image properly and the PCL renderer would not center it at all. I have not
looked at the code in a long time, but I thought that FOP did all the
layout before calling the renderer. So it should just be saying "put the
image here" and supplying the appropriate coordinates to the renderer. But
it is entirely possible that this had changed - or perhaps even more
likely - I am not remembering correctly. I have not looked at FOP code
much since the redesign started.
Okay... If you have time on your hands next week, I can send my fo
code to the list.I have to leave now (8pm here), so ...
have a nice week-end.Thanks for the answers, including the ones
about shorthands ;-)Bruno

RE: PCL renderer limitations
Yeah,
Bruno- you've got nothing to worry about with your English. I didn't even
once assume English wasn't your first language.
Stuff
like IIRC and AFAIK ("as far as I know") are just shorthand ways of writing
common phrases that some of us seem to have picked up from being on usenet too
much.

RE: PCL renderer limitations
Hmmm.
These are interesting.
On the
table problem, could it be that the part that appears to not be printing is
actually outside of the printer's printable area?
How
much is the image off center? If it just appears to be a little off center it
may be because the PCLRenderer only supports images scaled in discrete steps.
FOP's layout is unaware of this, so it may be placing the image based on what it
thinks the actual scaled size is - not the size the PCLRenderer will produce.
IIRC images are placed by the upper left corner - so this could cause an image
to appear off center.
HTH,
Art
