Jeremias,
do you have a patch file of your work with PNG? Perhaps with a second
pair of eyes we could resolve that issue... ;-)
Regards,
Matthias

Matthias is right. The PNGs need to be decoded and re-encoded. Some time
ago I've made experiments to embed PNG files without re-encoding them
but I haven't gotten that to work. Somehow the data was not quite right
so Acrobat barked at me with its usual unhelpful error messages. :-( At
the moment the only data formats we can embed without re-encoding are
JPEG and CCITT Group 3 and 4.
BTW, inside PDF there's no such thing as PNG or GIF. PDF uses its own
representation of bitmap images. So that means we always have to
interpret an image file and convert it to PDFs internal objects.

Hi Adam,
I think the cause of the 30sec delay is that PNGs aren't embedded
natively into the PDF and they must be transcoded first.
It would be really nice, if the FOP-Team could fix this issue, since
this problem also occurs when using PNGs inside SVGs and converting PNGs
to JPEGs isn't so easy in this case.

Matthias

Hi there!
Im currently having a strange effect. I use PNG images in my XSL to
create PDFs.
I have real performance problems (the XSL is quite complex and looks
fancy with many images)
If I use PNGs it takes 30s to create a PDF.
If I use JPGs it takes only 2,5s to create the same PDF (JPGs created
from the PNGs)
Im creating the PDFs over the FOP_IF and with concatenation of more
FOP_IF files.
Can anybody explain this to me? I would need to use PNGs as the printer
likes them more.
Is there any other format which is even more faster? (Giff or anything
else?)
Thanks in advance!!!
