PDF compression with Java, want size even smaller

Postby PDF compression on Tue Oct 18, 2011 1:57 pm

I am using Apache Fop 1.0 to create PDF documents, which uses the FlateFilter to compress the content. The FOP uses the DeflaterOutputStream DEFAULT_COMPRESSION under the cover. I have not found any possibility to set it to BEST_COMPRESSION.

The PDF contains several images generated by a graphics program. Those generated images are quite huge.

Is there anyway to reduce the file size.

You can put objects into stream and compress the stream. See this example:
Code: Select all
C:\>pdfleo --data-streams=compress \
   --object-streams=generate source.pdf target.pdf


FOP does not support object streams.
