Hi, when I extract pages using QuickPDF, pages are much bigger than extracting them with Adobe Acrobat itself.

Page 102 - 2106 Kb - 61 Kb

Page 411 - 2100 Kb - 55 Kb

Anyone knows why?

Regards,

Hi Jose!

Are there any images on these pages?
If there's one image reference for each page inside the pdf... QuickPDF put it on each extracted page? Does the extracted pages from Acrobat and QuickPDF looking identical?

Best regards,
Ingo

One thing that can help. When I was Zipping the 4 files to send to you (just in case), the Ratio for Acrobat pages was 16% and the Ratio for QuickPDF pages was 92%!!!
ZIP File Size is 427 Kb.

Hi Jose!

In this case perhaps you should try functions like
CompressContent
CompressPage
CompressFonts
CompressImages
first.

The problem is that it�ll take more time to extract pages in my procedure...
I think that I�ll need another way to do this.

Hi Jose!

Did you try the compress-functions?

No. The problem itself is not the size of the extracted page. The problem is that it is taking much more time to extract these pages than other PDF files and it�s taking a long time to extract all the pages of the file.
I think that the problem is in the source file.
Today I�ll be studying this problem.
I�ll let you know of any solution.
Thanks anyway.

Do you know of any other PDF Library that I can use to extract pages from a PDF document?
I want to see where is the problem.

I�m here again Ingo. Embarrassed

As you can remember, I need to extract pages from PDFs Documents. Everything was going fine, but with ONE Publication, the extracted page was 1.215 Mb size from a 240 pages Document with 13.226 Mb size.
When I extract the same page from Adobe Acrobat professional 7 the size is 39 Kb.
For this Publication I wrote a piece of code using Adobe Acrobat SDK, but it�s giving me a lot of problems (Out of Memory Error, Server Error, etc). The code is:

LPARAMETERS    toPDFDoc, tcFileNameFrom, tcFileNameTo, tnNumerodaPagina

LOCAL    llSourceDoc, loJSObject, loExtractedDoc

llSourceDoc    = toPDFDoc.Open(tcFileNameFrom)
loJSObject     = toPDFDoc.GetJSObject()
loExtractedDoc = loJSObject.ExtractPages(tnNumerodaPagina - 1, tnNumerodaPagina - 1)
               = loExtractedDoc.SaveAs(tcFileNameTo)
               = loExtractedDoc.CloseDoc()
               = toPDFDoc.Close()

RETURN

Do you know of any other method to extract pages from a PDF Document?

Have you tried http://www.pdfhacks.com/pdftk/ - pdftk ? It's based on iText, and comes with complete source code. There's a .NET port of iText which you may want to use if pdftk works for you.

Hi Jose!

The real PDF-expert here is Chicks ;-)
You should try pdftk/iText.
There's a C#-version iTextSharp, too.
