Need to find/replace text in PDF without altering layout

[Philip Tenn]

All,

I am trying to find and replace text in a PDF.  However, when I do so, my PDF format changes completely.  Here is my code:

                   PdfLoadedDocument loadedDocument = new PdfLoadedDocument(GetStreamFromUrl(inputFile));

            logger.Info($"Successfully got PDF Loaded Document from {inputFile}.");

            PdfLoadedPageCollection loadedPages = loadedDocument.Pages;

            PdfDocument newPdfDocument = new PdfDocument();

            foreach (PdfPageBase page in loadedPages)

            {

                string extractedText = page.ExtractText();

                foreach (var item in bindVarDictionary)

                {

                    extractedText = extractedText.Replace(item.Key, item.Value);

                }

                PdfPage newPage = newPdfDocument.Pages.Add();

                //Create PDF graphics for the page

                PdfGraphics graphics = newPage.Graphics;

                //Set the standard font.

                PdfFont font = new PdfStandardFont(PdfFontFamily.Helvetica, 20);

                //Draw the text.

                graphics.DrawString(extractedText, font, PdfBrushes.Black, new PointF(0, 0));

            }

Does anyone know how I can do a simple find/replace of text in a PDF without totally changing my formatting?

Thanks,

Philip
