Invalid copy pdf pages

[burz00m21]

In my example, when I copy each page, an empty space is added to the right.
The example in the attachment - https://1drv.ms/u/s!AodGrH0MILN8jmedq79TK9RsfxLu?e=SDDulr
Source file: source.pdf,
Response file: response.pdf
Code:

Code: Select all

        public static Stream CopyPdfFile(Stream sourceFile)
        {
            var targetPdf = new PdfDocument();
            var sourcePdf = new PdfDocument(sourceFile);

            foreach (PdfPageBase sourcePage in sourcePdf.Pages)
            {
                var targetPage = targetPdf.Pages.Add(sourcePage.Size, new Spire.Pdf.Graphics.PdfMargins(0, 0));
                targetPage.Canvas.DrawTemplate(sourcePage.CreateTemplate(), new System.Drawing.PointF(0, 0));
            }

            var response = new MemoryStream();

            try
            {
                targetPdf.SaveToStream(response);
                response.Position = 0;

                return response;
            }
            catch
            {
                response.Dispose();
                throw;
            }
        }

Dear Lgor,

I got your files from my email. Thanks for your sharing.
As your source pdf page's rotation angle is 270, so page size of target Pdf should be SizeF pageSize = new SizeF(sourcePage.Size.Height, sourcePage.Size.Width). Please refer to the modified code below.

Code: Select all

public static Stream CopyPdfFile(Stream sourceFile)
            {
                var targetPdf = new PdfDocument();
                var sourcePdf = new PdfDocument(sourceFile);
                 SizeF size;
                foreach (PdfPageBase sourcePage in sourcePdf.Pages)
                {
                     if (sourcePage.Rotation == PdfPageRotateAngle.RotateAngle270)
                     {

                       size = new SizeF(sourcePage.Size.Height, sourcePage.Size.Width);
                     }
                   else
                    {
                      size = sourcePage.Size;
                    }
                     var targetPage = targetPdf.Pages.Add(size, new Spire.Pdf.Graphics.PdfMargins(0, 0));
                     targetPage.Canvas.DrawTemplate(sourcePage.CreateTemplate(), new System.Drawing.PointF(0, 0));
                   }

                var response = new MemoryStream();

                try
                {
                    targetPdf.SaveToStream(response);
                    response.Position = 0;

                    return response;
                }
                catch
                {
                    response.Dispose();
                    throw;
                }
            }

Will this code work for all types of rotation? Why exactly for 270 the width and height are swapped?

[burz00m21]

probably for 90, too

Hi Lgor,

The code we provided is for your PDF which has 270 degree rotated pages. You could change the condition as below to apply to the 90 rotation. If there is other question, please feel free to write back.

Code: Select all

if (sourcePage.Rotation == PdfPageRotateAngle.RotateAngle90|| sourcePage.Rotation==PdfPageRotateAngle.RotateAngle270)
{
      size = new SizeF(sourcePage.Size.Height, sourcePage.Size.Width);
}

Sincertely,
