Flush a PDF?

[domfe]

Hello.
Is there a way to flush the PDF content to disk and continue adding pages?
I have to create a huge PDF file and on small systems it fills the memory. When this happens the document creation takes a lot of time and becomes almost unbearable.
So I'm looking for a way to generate some pages, save to disk, free some memory, then generate other pages, flush and so on.

Thank you

Sadly, it won't be possible. This topic was mentioned already on libHaru group: https://groups.google.com/d/msg/libharu/9SH_NCCbQUI/gS9cTzzqAwAJ
