multithreading in PDFBox 2.0
Hi,
I used to work with PDFBox 1.8, and it was not thread safe. Like rendering
of multiple pages at the same time was not possible (not reliable).
The only way was to create new PDDocument of that single file in every
thread.
Is there any changes in PDFBox 2.0 in this respect?
Is it possible to render pages to images in multiple threads? (without
opening new PDDocument in every thread)
Best regards
Juraj Lonc

Unofficially reading different pages from a single PDDocument does now support multi-threading, so you can share a PDDocument between threads and create a PDFRenderer on each thread.
