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().

text extraction : cannot see why: QP.SetOrigin(1);...

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.
