[libreoffice-users] size of LibreOffice RAM when converting towards pdf

Hi,

I have just a 10 Mo .ppt including around 30 jpeg images.
I want to convert it towards PDF using LibreOffice, while using a Java program.

To do so, I use the LibreOffice SDK from Java, with socket connection (due to streaming) between 
Java/LibreOffice.
While the original document size sounds not that high, LibreOffice raises up to 3 Go (!) of RAM.

What do you think about that numbers ?

While looking for a way to decrease the RAM used by LibreOffice, I wondered about the folllowing:

- what is the version of PDF for the created PDF doc ?

- are you using JPXDecode ("a lossy or lossless filter based on the JPEG 2000 standard, introduced 
in PDF 1.5") for not converting jpeg images ?

- are you doing streaming during the transformation process ?

Thanks for your responses.

Regards,
Dominique
