Let's see one PDF file, I uploaded it here:
http://depositfiles.com/files/3945338
Let's select the 3rd page and call GetPageText twice.
GetPageText(0) returns an empty string, but GetPageText(3) works much better, it returns:

Why GetPageText(0) gives not good results?
Many thanks in advance.

Hi!
GetPageText(0) is faster ... but older and more buggy.
GetPageText(3) is not so fast but not so buggy... and it offers more informations - so take "3"...
It's like it is ;-)
Best regards,
Ingo

Thank you, Ingo (our pdf expert).
I have a PDF file, and GetPageText(3) returns an empty string, but GetPageText(4) extacts the text from that PDF. Is the 4th parameter better than the 3rd parameter?
Is there a guarantee method of a text extraction?
As I understand, GetPageText(0) isn't recommended.

Hi!
I'm not the expert ... but (it seems to me) the only one looking here in a regularely way ;-)
I've never used option 4 but you can see that the developements 0-4 went different ways ;-) I prefer option 3.
best regards,
Ingo
