embedding pictures
Hi
is ist possible to specify the compression rate
for images to be embedded in an pdf file??
it is very important to me, because i need the
images in a higher quality than fop embedds them
until now - without any configuration changes.
it would be great, if somebody could help me
out of this.
thanx
daniel

Re: embedding pictures

Hello everybody,
About the image , I have submitted this question longtime ago but had no
answer . I try once more :-)
When we use external-graphic, the image is embedded in the Pdf file
generated by Fop, for now.
Is there any way to creat a link in the Pdf file to the image file and do
not embedd the image while using external-graphic ? So we can reduce the
size of the file.
Thank you for any suggestion !
Nam

Hi Daniel
Maybe. I think the problem is the quality of the images you want to use.
If the images you use have a low resolution (for example, because they
get scaled up), you get lousy results on high resolution printers. That
applies to png, tiff etc., too. Don't know if that helps you, though.

Also Eric Dalquist has indicated that he has got code to embed jpeg's
directly into pdf.
Unfortunately he has not posted his changes to the list yet (that I know
of).

Hi Jeremias,
is it better for now not to embed jpegs and to use
another format? if this is the case, wich format
should I use for getting the best result in quality?
thanx

That won't help a lot, because FOP currently only implements loss-less
compression (ZLib/flate). Specifying a compression rate will only change
the speed of encoding and the size of the image in the PDF, but not the
quality of the image. I guess you're trying to embedd JPEG images, right?
