Splitting large PDF into multiple PDF

I am having issue while splitting a large pdf into multiple pdfs files.

Details

There are 10 pdf files concatenated together into a large single PDF file. There is a separator page between each PDF file.

In reality the large pdf will be given to us by client using the separator that we provide. For this sample application though I have created “Sample.pdf” and it is provided in attached solution.

I want to split this large pdf into individual PDF file. The separator is used to detect end of single document. I use TextAbsorber to read the text from the page.

Issue

In the code I loop through all the pages of “Sample.pdf” While debugging, I see "Pages" collection has all the pages, however when I execute application without debugging all pages from 3rd page onwards are null.

See the attached screenshots


Executing the Application

1>Extract attached zip

2>Open PDfSplitter solution. Include your own license file into "Lib" folder.

3>Set the license file's build Action to "Embedded Resource"

4>Execute the application.


I also wanted to know if this is recommended solution to divide and then detect multiple pdf documents?

I had a similar issue when using TextAbsorber version 11.5 to split a large PDF document. It would fail from the 3rd page onward. Interestingly, when I reverted to version 10.2 it worked with no problem (I did not try any other versions in between). I don’t know if this is related, but if you have time to experiment with an earlier version of TextAbsorber, you may find that it works for you as well.

I still have problems when I use version 11.5, but no problem with the earlier 10.2 version I had been using before. Hope that helps somehow.
