Hi,
I've a problem when I create a pdf with more 100.000 pages (only text). This file is over 1.4 GB and it's too large. So, I've tryed to generate a pdf with more 3000 pages to do some tests: After the creation of this file, If I print the same file with pdf creator or with Microsoft pdf printer the size of the new file becomes more then half size. Why? Thanks, regards

If you are not using the DA functions, the whole file has to be loaded into memory to process. For a file size of 1.4GB this might mean that your process memory space is near to or over the limit.
Please tell us (1) what programming language you are using; (2) what version of QPDF; (3) whether you are using the direct access function set or not; (4) whether you are developing a 32-bit or a 64-bit application; (5) what steps you are already taking to compress or minimize the size of the file; (6) what error messages you are seeing, if any. Then someone may be able to offer some advice. Without this information there is not much that anyone can say.

(1) what programming language you are using; Visual Studio 2013 (2) what version of QPDF; Ver 13.12 (3) whether you are using the direct access function set or not; I use both functions (4) whether you are developing a 32-bit or a 64-bit application; 32 bit (5) what steps you are already taking to compress or minimize the size of the file; I use, for example, oQP.CompressContent() (6) what error messages you are seeing, if any. I've no error. |

Hi Marco,
there are other compress options, too: http://www.debenu.com/docs/pdf_library_reference/DocumentProperties.php The compress functionalities works only for things you're putting inside - not things which are already inside in an existing document. Please read this,too: http://www.debenu.com/kb/can-i-compress-my-pdf/ |

WHILE creating the new pdf with QuickPDF you can use the compress functionalities.
Using already made pdf-files won't work.

Perhaps an answer with your relevant code would help?
Actually it's like looking into a glass bowl ;-) |
