Hi,

I want to know how to rotate a pdf page say by 90, 180 and 270 degrees. I tried the following code but when I rotate and transform the resulting page is blank. If not rotated the page appears in the rectangle bounding box.

PdfDocument inputDocument = PdfReader.Open(filename, PdfDocumentOpenMode.Import);
PdfDocument outputDocument = new PdfDocument();
for (int idx = 0; idx < inputDocument.PageCount; idx++)
{
PdfPage page = inputDocument.Pages[idx];
PdfDocument singlePageDocument = new PdfDocument();
singlePageDocument.AddPage(page);
singlePageDocument.Save("C:\\NewTemp\\temp"+idx.ToString()+".pdf");
outputDocument.AddPage(new PdfPage());
page = outputDocument.Pages[idx];
page.Orientation = PdfSharp.PageOrientation.Landscape;
XGraphics gfx = XGraphics.FromPdfPage(page);
XPdfForm form = XPdfForm.FromFile("C:\\NewTemp\\temp"+idx.ToString()+".pdf");
gfx.RotateAtTransform(90, new XPoint(0, 0));
gfx.DrawImage(form,new XRect(140, 80, 50, 50 * Math.Sqrt(2)));
gfx.Save();
}
outputDocument.Save("C:\\NewTemp\\Rotated.pdf");

Let me know if there is a simple way to rotate a page.

Thanks,

Sai.

Hi Sai,

I just did:

PdfDocument inputDocument = PdfReader.Open(filename, PdfDocumentOpenMode.Import);

foreach (PdfPage page in inputDocument)
{
page.Rotate = 0;
page.Orientation = PdfSharp.PageOrientation.Portrait;
}

That worked for me. However, I'm also looking to resize the page and I haven't found an easy way to do that yet.
