I want to create a new pdf file by merging multiple files. But when I am trying to add a bookmarks like table of contents, Cover page etc. then I am unable to do it. As I have tried many code samples posted in the community and also from Samples that we can find out in Download section (Apryse Developer Portal) but still I am unable to get the desired results. I am using PdfTron latest version
Here is my Sample code I am using:
try
{
_logger.LogInformation("Starting boardpack/book files export.");
var migrationSettingForMeetingPaqList = _resourcesQuery.GetMigrationSettingForMeetingsPaq(customerId)?.ToList() ?? new List<MigrationSettingMeetingPaq>();
string lis = "Sample demo Liscense";
PDFNet.Initialize(lis);
string directoryPath = fileDumpPath;
using (PDFDoc mergedPdf = new PDFDoc())
{
mergedPdf.InitSecurityHandler();
string fileExtension = string.Empty;
//string[] files = Directory.GetFiles(directoryPath, "*.*");
foreach (var filePath in exportedBooks.Take(5))
{
try
{
if (filePath.FileName != null)
{
fileExtension = Path.GetExtension(filePath.FileName).ToLower();
}
if (fileExtension == ".pdf" || fileExtension == ".pptx" || fileExtension == ".docx" || fileExtension == ".xlsx")
{
using (PDFDoc docToMerge = new PDFDoc(directoryPath + "\\" + filePath.FileName))
{
if (fileExtension == ".pdf")
{
mergedPdf.InsertPages(mergedPdf.GetPageCount() + 1, docToMerge, 1, docToMerge.GetPageCount(), PDFDoc.InsertFlag.e_none);
}
else
{
WordToPDFOptions options = new WordToPDFOptions();
pdftron.PDF.Convert.ToPdf(docToMerge, filePath.FileUrl);
//tempPdfDoc.InsertPages(tempPdfDoc.GetPageCount() + 1, tempPdfDoc, 1, tempPdfDoc.GetPageCount(), PDFDoc.InsertFlag.e_none);
//string outputFilePath = Path.Combine(fileDumpPath, "merged_output23.pdf");
//string outputDirectory = Path.GetDirectoryName(outputFilePath);
//if (!Directory.Exists(outputDirectory))
//{
// Directory.CreateDirectory(outputDirectory);
//}
//// Save the PDF file
//tempPdfDoc.Save(outputFilePath, SDFDoc.SaveOptions.e_linearized);
//ConvertToPdf(docToMerge, filePath, fileDumpPath);
mergedPdf.InsertPages(mergedPdf.GetPageCount() + 1, docToMerge, 1, docToMerge.GetPageCount(), PDFDoc.InsertFlag.e_none);
}
}
//else if (fileExtension == ".png")
//{
// using (PDFDoc pdfdoc = new PDFDoc())
// {
// Console.WriteLine("Converting from XPS");
// pdftron.PDF.Convert.FromXps(pdfdoc, filePath + "simple-xps.xps");
// pdfdoc.Save(fileDumpPath + "xps2pdf v2.pdf", SDFDoc.SaveOptions.e_remove_unused);
// // Console.WriteLine("Saved xps2pdf v2.pdf");
// }
//}
}
}

Console.WriteLine($"Error processing file {filePath}: {ex.Message}");
