GetPageText returns not all text

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hello guys,

I'm implementing search functionality for my PDF viewer.
I'm using GetPageText function to get text on page and then find target string.
When target string is found, text is highlighted on page using returned in GetPageText text bounds.

Everything works fine. But for some documents, pages GetPageText returns not all words on page, so search fails. 

In reference guide there is statement "The SetTextExtractionWordGap, SetTextExtractionOptions and SetTextExtractionArea functions can be used to adjust the text extraction process".
But what function I must call, with what parameters, to return all words on page?

Or maybe GetPageText is obsolete and ExtractPageTextBlocks must be used instead?

P.S.
I'm using Quick PDF Library 9.16.

	I've realized that problem was in my csv parsing code. So for now everything is normal.

	Mykhaylo, Using ExtractPageTextBlocks removes the needs to parse a CSV file which can be a little trick at times. The SetTextExtractionWordGap function is very very rarely needed and the SetTextExtractionOptions is useful when you need the results to be reformatted a little to make extraction easier. Andrew.
