Hello,

Thanks for your inquiry.
The following code demonstrates how to split a single PDF page into several equally sized pages in the horizontal and vertical directions.

Code: Select all

    static void Main(string[] args)
    {
        PdfDocument doc = new PdfDocument();
        doc.LoadFromFile("test.pdf");

        //Number of pieces in the horizontal direction
        int horizontalNumber = 3;
        //Number of pieces in the vertical direction
        int verticalNumber = 2;
        //!!!Note, horizontalNumber and verticalNumber must be > 0

        //Split the page horizontally into equal-sized pages
        PdfDocument temPdf = Split(doc, horizontalNumber, true);
        //Split the page vertically into equal-sized pages
        PdfDocument newPdf = Split(temPdf, verticalNumber, false);

        //Save the Pdf document
        string output = "output.pdf";
        newPdf.SaveToFile(output);
    }

    public static PdfDocument Split(PdfDocument pdf, int number, bool isHorizontal)
    {
        //Create a new Pdf
        PdfDocument newPdf = new PdfDocument();
        //Remove all the margins
        newPdf.PageSettings.Margins.All = 0;

        //Spilt pages
        foreach (PdfPageBase page in pdf.Pages)
        {
            //Set the page size of new Pdf
            if (isHorizontal)
            {
                newPdf.PageSettings.Width = page.Size.Width;
                newPdf.PageSettings.Height = page.Size.Height / number;
            }
            else
            {
                newPdf.PageSettings.Width = page.Size.Width / number;
                newPdf.PageSettings.Height = page.Size.Height;
            }
            //Add a new page
            PdfPageBase newPage = newPdf.Pages.Add();
            PdfTextLayout format = new PdfTextLayout();
            format.Break = PdfLayoutBreakType.FitPage;
            format.Layout = PdfLayoutType.Paginate;
            //Draw the page in the new page
            page.CreateTemplate().Draw(newPage, new PointF(0, 0), format);
        }       
        return newPdf;
    }

Hi,
thank you for the answer.
The code is working, but what if i want to cut not in same size but for exaple the first block in a certain width and the second block in another? Is that possible?

Hi,

Thanks for your response.
Please refer to the following code to split a page into two blocks with the different sizes.

Code: Select all

 PdfDocument doc = new PdfDocument();
            doc.LoadFromFile("input.pdf");
            PdfPageBase page = doc.Pages[0];
            float width = page.Size.Width;
            float height1 = 300;
            float height2 = page.Size.Height - height1;
            PdfDocument newDoc = new PdfDocument();
            PdfPageBase newPage = newDoc.Pages.Add(new SizeF(width, height1), new Spire.Pdf.Graphics.PdfMargins(0));
            page.CreateTemplate().Draw(newPage.Canvas, new PointF(0, 0));
            newPage = newDoc.Pages.Add(new SizeF(width, height2), new Spire.Pdf.Graphics.PdfMargins(0));
            page.CreateTemplate().Draw(newPage.Canvas, new PointF(0, -height1));

            string result = "result.pdf";
            newDoc.SaveToFile(result);
