From my limiting reading on the structure of PDF the number of pages in a document is not kept in a single field( I could be wrong). If the number of pages is not in a single field those PDF Sharp contain a function similar to Foxit PDF Editor called optimize which removes unneed information from the pdf. Someback ground information may shed some light on my question. I currently have an application which converts a printed document in to a pdf using a scanner and ocr software. The program will also split the pdf into a smaller pdf based on certain business rules. For example a ten page pdf maybe split into five two page files. Currently they way I determine the number of pages in the new split files those not work correctly, however if I manually run Foxit PDF Editor and goto Edit > Optimize and then rerun my program I get the correct information. So my questions are is there a way to determine the number of pages in a file using PDF metadata and number of pages field. If not does PDF Sharp have a method which removes/corrects the pdf info. Thanks |

You can try it yourself. Just create a Release build of PdfSharp.Explorer and open the document with it. PdfSharp.Explorer creates a new file with an underscore appended to the filename (test_.pdf for test.pdf). Open this file and check if the pagenumber is corrected. |
