Demanding some help with pdfbox performance issue

[mehdi khalfaoui <me...@gmail.com>]

Hello pdfbox team,

First of all, thank you for all the amazing work that you are doing
everyday for this great tool.

I'm contacting you because I need your advice in using pdfbox to the
fullest. I'm trying to print a scanned pdf document and it's very slow.
After a lot of debugging and searching, I came cross this link
https://issues.apache.org/jira/browse/PDFBOX-3046 which describes almost
what I'm experiencing. Specially the comment by Mr Petr Slaby.

My code is simple as

Doc doc = new SimpleDoc(new PDFPageable(PDDocument.load(document),
Orientation.AUTO,false,300), DocFlavor.SERVICE_FORMATTED.PAGEABLE, null);


job.print(doc, proprietes);

I'm not sure, but I believe there is some issuing when ttf is in play.

Thank you in advance for your help,

Mehdi KHALFAOUI

Hello,

The issue also explains the solution: put a non-zero value for the "dpi" 
parameter of PDFPageable / PDFPrintable. Start with 300, to see if it is 
fast enough... if yes, try 600, i.e. get closer to printer resolution.

I'm surprised that a scanned image would be slow. The problem happens 
with some transparencies - if possible, please share the PDF (upload to 
sharehoster, don't post).

PS: in the future (next topic), please use the users mailing list, not 
the dev mailing list.
