text extraction

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

   cannot see why:
	QP.SetOrigin(1);
        QP.SetTextExtractionArea( 0, 0, QP.PageWidth(), QP.PageHeight());    
	QP.GetPageText( 8); // <- ok, some text

works as expected, but

	QP.SetOrigin(0);
	QP.SetTextExtractionArea( 0, 0, QP.PageWidth(), QP.PageHeight());   
	QP.GetPageText( 8); // <- returns empty string

will not ?
Any help welcome.

	With set origin 0, the origin of measurement is the bottom left corner. So the vertical co-ordinate of the top of the area (which you must supply as the second parameter in SetTextExtractionArea) should be -QP.PageHeight().
