Hi, has anyone noticed that pdfsharp doesn't deal very well with non-standard page sizes?

I've got a pdf with strange height and width (16.54 x 11.70 in) which is in landscape. I need to add some outlines to it. When I do so (with PdfSharp) and save it, the document has been converted to portrait and subsequently almost half of the page is cut off.

So, I add a routine to rotate the document to landscape before I add the outlines.

PdfDocument pdf = PdfReader.Open(pdfFile, PdfDocumentOpenMode.Modify);

foreach (PdfPage page in pdf.Pages)
{
page.Orientation = PdfSharpMod.PageOrientation.Landscape;
}

This yields the same result. It still is rotated to portrait, even though PdfSharp presumably knows that the contents of the page is not in portrait.

I haven't fixed this issue but I managed to create the output that I wanted.
The pdf was actually landscape when it should have been portrait, so I gave up trying to fit it on a landscape page and made it portrait by:

page.Rotate = 0;
page.Orientation = PdfSharpMod.PageOrientation.Portrait;

If anyone's interested, I've worked out how to rescale the document to A4.

// Open the pdf as a form

XPdfForm form = XPdfForm.FromFile(pdfFile);

for (int i = 1; i <= form.PageCount; i++)
{
// Create a new page in the new pdf

PdfPage newPage = pdf.AddPage();
newPage.Size = PdfSharpMod.PageSize.A4;
newPage.Rotate = 0;
newPage.Orientation = PdfSharpMod.PageOrientation.Portrait;
double width = newPage.Width;
double height = newPage.Height;

// Prepare the contents of the new page

XGraphics gfx = XGraphics.FromPdfPage(newPage);

// Make a new bounding box for the contents of the page

XRect box = new XRect(0, 0, width, height);

// Select the right page number in the current pdf

form.PageNumber = i;
form.Page.Rotate = 0;
form.Page.Orientation = PdfSharpMod.PageOrientation.Portrait;

// Add the contents of the page to the new page

gfx.DrawImage(form, box);
}
