I have an .NET application for pdf text extraction which returns an empty text from 'GetPageText(7)' function after changing the default window scaling setting to 125%.

Can we use a function like 'SetTextExtractionScaling' or 'SetTextScaling' to control the scaling setting before text extraction?

Can someone help me on this?

Thank you.

Hi Nirmani,

QP.NormalizePage(0) is always good before calling the text extraction functions.
Then you can deal with the next two functions (they can only be applied to the selected document you're working with)...
QP.SetTextExtractionScaling(0, 2, 8);
QP.SetTextExtractionWordGap(0.2);
and then the GetPageText(7).

Cheers,
Ingo
