I have an one input PDF file of 4 pages, my application has to duplicate each and every pages in the PDF. The final output PDF file has 8 pages in it.

I am sucessfull in duplicating the pages but i have problem in the size of the PDF created. As the pages are double it is obvious to get the size double the input PDF file. But for some of the files is 8-10 times greater than the input PDF.

I use Acrobat 6.0 dll in my application. The input PDF is created in acrobat version 6.x and 7.x.

Any idea on this.
