Can you please tell me how to preview selected layer before using delete later?]]> Tue, 19 Jun 2012 13:24:57 +0000 http://www.quickpdf.org/forum/remove-watermarks_topic2238_post9795.html#9795 http://www.quickpdf.org/forum/remove-watermarks_topic2238_post9511.html#9511 Author: Ingo

Hi Hans!

This would be hard stuff ... nearly impossible.
If you wanna use such functionality you should prepare
the pdf-documents in a different way.
First you should use "SetLayer".
Then insert your watermark and save it.
If you want to remove the watermark you
should check the layercount first (is there an additional layer?)
and then you can use "DeleteLayer" and your watermark is off.

Cheers, Ingo

Hello,
I can add some watermarks (stamps) on all pages of an PDF.
I do this with

DrawRotatedText

This works fine.
My question is:
Is there a way to remove the watermark again if the user want ?

---------------------------
    for ($p = 1; $p <= $qp->PageCount(); $p++)
    {
        $qp->SelectPage($p);
        $qp->SetOrigin(1);           
        $qp->SetMeasurementUnits(0); 
        $qp->SelectFont($fid);
        $qp->SetTextAlign(1);   
        $qp->SetTextSize($ts);
        $qp->SetTextColor(0, 1, 1);
       $qp->SetTransparency($transp);
         $qp->DrawRotatedText($qp->PageWidth() / 2, $qp->PageHeight() / 2 + 40, $angle, $watermartext);
    }
    $qp->SaveToFile("$actdir/view/work.pdf");
----------------------------

regards
hans
