Thank you Andrew

Your's example much more simple & clear.

So negative width is a horizontal mirror & negative height is vertical mirror.
Adjusting x,y I'm can draw copies in required places.

Here is some interesting code you might enjoy

            QP.LoadFromFile("testdebenu (1).pdf", "");
            QP.DeletePages(2, 99999);   // Make sure we only have 1 page

            QP.SetOrigin(1);
            double pw = QP.PageWidth() / 2;
            double ph = QP.PageHeight() / 2;

            QP.NewPage();
            int capId = QP.CapturePage(1);

            QP.SelectPage(1);

            QP.DrawCapturedPage(capId, pw, ph, pw, ph);
            QP.DrawCapturedPage(capId, pw, ph, -pw, ph);
            QP.DrawCapturedPage(capId, pw, ph, pw, -ph);
            QP.DrawCapturedPage(capId, pw, ph, -pw, -ph);

            QP.SaveToFile("out.pdf");

If you need to use a negative width or height then you need to adjust you x, y position accordingly.

Andrew.

So I'm trying this sequence:

int Result=qp.NewContentStream();
qp.SetContentStreamFromVariant(BytesMessage1);
qp.MoveContentStream(Result, 1);

Where "ByteMessage1" is a converted string with transformation matrix(I'm mentioned above)

For my simple file it works quite well.

Hi!

Like i've told:
You have to do it by your own and with your own calculations.
QP won't support it directly.
Have a look in the developer guide and the reference to see what's possible and what not.

Cheers, Ingo

Hi Ingo
So I'm made one sample pdf & then mirror it by Quite plugin.
Then I'm examine content with RUPS utility
So in mirrored file I'm found an additional stream placed before main stream with data
It contents:
-1 0 0 1 144.57 0 cm
This is a transfomation matrix.
So could you give me some guidelines how I'm can place this matrix in my PDF content with QP library functions?
Best regards
Serge

Hi!

QuickPDF offers the rotate functionality...
If this won't feed your needs only personal maths/calculations will bring you success i fear ;-)

Cheers, Ingo

Is it possible  to draw mirrored page with DrawCapturedPage or some other method?
I'm can draw images by use imagematrix function, but could it possible with captured page?
