Hi,

I'm trying to print the following PDF, which contains an A3 landscape page

http://home.in.tum.de/%7Ewengera/Din_A3_Datenblatt.pdf - http://home.in.tum.de/~wengera/Din_A3_Datenblatt.pdf

in A4 portrait mode. That means, I want it to have 50% scaled and rotated by 90°.

I do:

String customPrinter = qp.NewCustomPrinter(printerName);
qp.SetupCustomPrinter(customPrinter, 1, 9); //1: paper size. 9: DMPAPER_A4
int o = qp.PrintOptions(1, 1, "bla"); //auto-scale, auto-rotate
qp.PrintDocument(customPrinter, 1, qp.PageCount(), o);

It is rotated and scaled correctly, but shifted to the right! See the result:

Is this a bug? Did I miss anything?

Thanks :-)

I have found a rather simple solution, that works at least for my example PDF.

//rotate all rotated pages back to 0 degrees
for (int page = 1; page <= qp.PageCount(); page++)
{
qp.SelectPage(page);
if (qp.PageRotation() != 0)
qp.RotatePage(0);
}

Then, when printing with auto-scaling, but no auto-rotation, everything works fine :-)

Nevertheless I hope that the bug gets fixed in the next release.

Brilliant! Solved my problem.

For me certain large PDFs didn't scale properly according to the PrintOptions. But now it works OK as I just rotate pages before printing.

Cheers, Jason.

We will try and fix this for the 8.11 release. Pages with no rotation work well but we run into problems when the page rotation flag is set to 90, 180 or 270.

The solution to rotate the page to 0 degrees and then back again is the best solution and is quickest and the easiest for the time being.

Andrew.
