Split PDF based on content

[Greg_Ledford]

I have a large PDF that contains customer notices. The notice for each customer has an unknown number of pages. I need to split the PDF into the individual customer notices. The first page for each customer contains their name, account number, address, etc. The remaining pages contain account disclosures as well as images of checks written for their account.

Hello,

Thanks for your inquiry!

You can first mark the page index by some unique information like names which contained in the first page of each of your customer information, and then draw the pages of each customer to a new PDF according to the page index. Here I attached a simple demo.

Code: Select all

            PdfDocument pdf = new PdfDocument();
            pdf.LoadFromFile(filepath);

            PdfTextFind[] findResult = null;
            List<int> index = new List<int>();
            foreach (PdfPageBase page in pdf.Pages)
            {
                //Find text
                findResult = page.FindText(findString, TextFindParameter.WholeWord).Finds;
                foreach (PdfTextFind find in findResult)
                {
                    int pageindex = find.SearchPageIndex;
                    index.Add(pageindex);
                }
            }

            for (int i = 0; i < index.Count; i++)
            {
                int currentIndex = index[i];
                int nextIndex = 0;
                if (i.Equals(index.Count - 1))
                {
                    nextIndex = pdf.Pages.Count;
                }
                else
                {
                    nextIndex = index[i + 1];
                }
               
                PdfDocument newpdf = new PdfDocument();

                for (int j = currentIndex; j < nextIndex; j++)
                {
                    PdfPageBase page = pdf.Pages[j];
                    PdfPageBase newPage = newpdf.Pages.Add(page.ActualSize, new PdfMargins(0));
                    page.CreateTemplate().Draw(newPage.Canvas, new PointF(0, 0));
                }

                newpdf.SaveToFile("custom" + i + ".pdf", FileFormat.PDF);
                newpdf.Dispose();
            }
