I have a PDF that I need to extract certain pages out and create another pdf with just those pages. ISED seems to have the function: QP.ExtractFilePages Input, Output, Pages What I am passing is this: QP.ExtractFilePages PDFName, NewPDF, "1-2" When I do this the NewPDF does not get created. Any help on why this does not work? |

Update: I got it to create the file now but it only creates 1 page correctly. Page 1 is correct and then Page 2 is blank. |

Thanks Ingo, This function does not work for some of our PDF's. I tried another PDF it works but not others. Do you have any ideas why it would work for some PDF's but not others? I can email you the PDF it doesn't work for if you want. |

Hello mhc, I confirmed what you have described. and by editing the sample code of ExtractFilePages like below: //QP.ExtractFilePages(GetInputFolder() + "sign_me.pdf", GetOutputFolder() + "extracted_page_range.pdf", "2-5, 8, 10, 13-19"); sign_me.pdf works but Moby_Dick_NT.pdf does not work well and 13 pages of blank pages are produced. And I tested with other PDF files which I have, and encountered the strange things. Maybe this phenomena is because of my special environment. My OS is Japanese (But in my tests, no unicode paths are involved. ), and I develop with PHP and ActiveX. Anyway, I think your description can be confirmed in my environment. |

I think the problem come with an unusual contruction of the Pages directory in the pdf
Usualy, a pages directoy look like this
The count entry say how much pages are defined in the pdf and the kids entry show where the pages begin
When a Kid entry points to another page directory, ExtrafilePage is lost
In the sample the page 1 entry look like this
And the second one
This one is a sub-page directory and if this construction is not a bad one, it is also unusual.
The ExtratPageFile can't handle it.
