PDF compression with Java, want size even smaller

[PDF compression]

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.
