Hi, We are using pdfbox 3.0.0 as part of our project which aims at finding discrepancies between two similar documents created by external services. One thing we use it for is to render the pages of those documents to images and compare the rendered images. Those documents can be very large and therfore we are trying to optimize our resource usage. So we want to parallize the page rendering if possible. This leads to my question in relation to the PDFRenderer class (v3.0.0):
In the past we could observe problems with this multithreaded approach. And I understand that PDDocument is not thread safe, but what if I get all the PDPage objects first and then render them multithreaded? Essentially if the method PDFRenderer.renderImage(int pageIndex, float scale, ImageType imageType, RenderDestination destination) is passed the PDPPage object directly and not the pageIndex, it would not be needed to get the PDpage object from the PDPageTree. Do you know of possible limitations regarding multithreading the remainder of this renderImage method? To clarify I am currently testing this with a subclass of PDFRenderer so I could add this method: renderImage(PDPage page, float scale, ImageType imageType, RenderDestination destination) Thank you very much for your time and help Best regards / Mit freundlichen Grüßen Arno Dietsche brainsphere informationworks GmbH Elsenheimerstrasse 41 80687 Muenchen Germany Telefon: +49 89 203004-830 Telefax: +49 89 203004-849 Sitz der Gesellschaft: Muenchen Registergericht: Amtsgericht Muenchen HRB 154535 Geschaeftsfuehrer: Hans-Joerg Kamm, Volker Mattes Diese E-Mail enthaelt vertrauliche und/oder rechtlich geschuetzte Informationen.
