Hi, is there a way to have an Api to read array of PDF files and then combine into single PDF using itext 7? TIA

Answer 1

You can see Combining PDF documents using iText7 and C#

Answer 2

Managed to write a function that is combining 2 pdfs into 1 file. I used a console application. Not sure whether the same I can reuse within API.

private static void createPdf(string DEST,string SRC1,string SRC2)
        {
            //Initialize PDF document with output intent
            PdfDocument pdf = new PdfDocument(new PdfWriter(DEST));
            //PdfMerger merger = new PdfMerger(pdf);
            PdfMerger merger = new PdfMerger(pdf);

            //Add pages from the first document
            PdfReader reader = new PdfReader(SRC1);
            reader.SetUnethicalReading(true);
            PdfDocument firstSourcePdf = new PdfDocument(reader);           
            merger.Merge(firstSourcePdf, 1, firstSourcePdf.GetNumberOfPages());

            //Add pages from the second pdf document
            PdfReader reader1 = new PdfReader(SRC2);
            reader1.SetUnethicalReading(true);
            PdfDocument secondSourcePdf = new PdfDocument(reader1);
            merger.Merge(secondSourcePdf, 1, secondSourcePdf.GetNumberOfPages());

            firstSourcePdf.Close();
            secondSourcePdf.Close();
            pdf.Close();
        }
