Different page orientations in same PDF

[milltownham]

I would like to know if it is possible to determine the orientation of individual pages within a PDF document instead of just the overall document orientation. I have a sample PDF which has one landscape page and two portrait pages and I would need to identify and rotate the landscape page programmatically. I have also tried using actualsize.height and width but this always seems to return the height as the largest value in the sample, regardless of the page orientation. Is there any way for me to do this?

Hello,

Thanks for your inquiry.
After a check, we found the oritation of the first page in your file is potrit rather than landscape. Since it has already rotated 90 degree, it looks like "landscape". As for your requirement of getting the orientation of individual pages and rotate the first page. You could refer to the following code.

Code: Select all

            PdfDocument pdfDoc = new PdfDocument();
            pdfDoc.LoadFromFile(path);

            foreach (PdfPageBase page in pdfDoc.Pages)
            {
             // Determine the orientation of a certain page
             //PdfPageOrientation direction = page.Section.PageSettings.Orientation;
             //Since your first page has rotated 90 degree, if you want to turn it to be potrit- looked-like，
             // just set the rotate to 180 degree, that is, rotate 90 degree again.
                if (page.Rotation == PdfPageRotateAngle.RotateAngle90)
                    page.Rotation = PdfPageRotateAngle.RotateAngle180;
            }
            pdfDoc.SaveToFile("11351.pdf");


Also, you could justify the page size mannually to let the content keep landscape.

Code: Select all

PdfDocument newDoc = new PdfDocument();
            PdfPageBase newPage;
            //Expected width and height
            float width = doc.Pages[1].ActualSize.Width;
            float height = doc.Pages[1].ActualSize.Height;
            foreach (PdfPageBase page in doc.Pages)
            {
                newPage = newDoc.Pages.Add(new SizeF(width, height), new PdfMargins(0));
                if (page.Rotation == PdfPageRotateAngle.RotateAngle90)
                {
                    page.CreateTemplate().Draw(newPage, -360, -80);
                }
                else
                {
                    page.CreateTemplate().Draw(newPage, 0, 0);
                }           
            }

            newDoc.SaveToFile("resut1.pdf");
            System.Diagnostics.Process.Start("resut1.pdf");


Just choose the solution you need.
Let me know if I have made it clear.

Thank you for your help. I had not realised that the first page of my sample PDF was actually a portrait page rotated to appear landscape, so I was able to just set the rotation of all pages to RotateAngle0 so that every page now appears portrait and the height and width correspond with the displayed pages.
