Page truncate in right side for landscape orientation with trimmargins using PdfSharp

I am talking about PdfSharp. Portrait orientation works well with margin or without margin. But In case of landscape orientation, page truncate in right side once I set any margin using TrimMargins. I have tried same thing on sample code of pdfSharp and having same problem!!

Look pdf rendered well for following code

page = document.AddPage();
page.Size = PdfSharp.PageSize.A4;
page.Orientation = PageOrientation.Landscape;
gfx = XGraphics.FromPdfPage(page);
gfx.DrawString("A4 (landscape)", font,XBrushes.DarkRed, new XRect(0, 0, page.Width, page.Height),XStringFormats.Center);

But for following code pdf is not rendered well, truncate in right side

page = document.AddPage();
page.TrimMargins.Top = 5;
page.TrimMargins.Right = 5;
page.TrimMargins.Bottom = 5;
page.TrimMargins.Left = 5;
page.Size = PdfSharp.PageSize.A4;
page.Orientation = PageOrientation.Landscape;
gfx = XGraphics.FromPdfPage(page);
gfx.DrawString("A4 (landscape)", font,XBrushes.DarkRed, new XRect(0, 0, page.Width, page.Height),XStringFormats.Center);

Have any idea?
Thanks

Method 1

Could be a bug in PDFsharp.

As a workaround, do not set the orientation to Landscape, instead swap width and height when creating the page.

page = document.AddPage();
//page.Size = PdfSharp.PageSize.A4;
XSize size = PageSizeConverter.ToSize(PdfSharp.PageSize.A4);
page.MediaBox = new PdfRectangle(new XPoint(0, 0), new XPoint(size.Height, size.Width)); // Magic: swap width and height
//page.Orientation = PageOrientation.Landscape;

The default unit for margins is Points.
To get e.g. millimetres instead, you can write:

page.TrimMargins.Top = XUnit.FromMillimeter(5);
page.TrimMargins.Right = XUnit.FromMillimeter(5);
page.TrimMargins.Bottom = XUnit.FromMillimeter(5);
page.TrimMargins.Left = XUnit.FromMillimeter(5);

Method 2

Yes, this is a bug of PdfSharp

We can set the margins with orientation like bellow

page = document.AddPage();
//page.Size = PdfSharp.PageSize.A4;
XSize size = PageSizeConverter.ToSize(PdfSharp.PageSize.A4);
if(page.Orientation == PageOrientation.Landscape)
{
   page.Width  = size.Height;
   page.Height = size.Width;
}
else
{
   page.Width  = size.Width;
   page.Height = size.Height;
}

// default unit in points 1 inch = 72 points
page.TrimMargins.Top = 5;
page.TrimMargins.Right = 5;
page.TrimMargins.Bottom = 5;
page.TrimMargins.Left = 5;

Method 3

I had this same problem — very frustrating. To anyone whom the top solution didn’t work: try this!

Since PDFSharp can only handle graphics and transformations properly on pages in portrait orientation, my work-around on my project was converting the landscape pages to portrait with .page.Rotate = 0 upon input. Remember that these files are now sideways so keep that in mind when applying graphics and transformations. Then before saving the file, I converted the page back to landscape with .page.Rotate = 90. Worked fine for me! Good luck y’all.
