So I would consider the following workflow: So if you replace 'abcdef' with 'xyz' then the PDF will not display these 'xyz' as no glyphs are available for these letters to be displayed. if you have a text object with some text like 'abcdef' then the embedded font may contain glyphs for these ('abcdef' letters) only but not for other letters. The general issue is that text objects may use embedded fonts with specific glyphs assigned to specific letters. Thanks for all your answers and your help. I need a solution for text which is NOT in a Textfield. This keeps the formatation of the rest of text and does only change my searched text. Textfeld unbearbeitbar machen (sieht aus wie normaler text) Var value = (fieldKey) įorm.SetField(fieldKey, value.Replace(txt_SuchenNach.Text, txt_ErsetzenMit.Text)) PdfStamper stamper = new PdfStamper(pdfReader, newFileStream) PdfReader pdfReader = new PdfReader(existingFileStream) Using (FileStream newFileStream = new FileStream(fileNameNew, FileMode.Create)) String fileNameNew = (FileStream existingFileStream = new FileStream(fileNameExisting, FileMode.Open)) The second try I had was way better, but needs fields where I can change the text inside: string fileNameExisting =path Text.Replace(txt_SuchenNach.Text, txt_ErsetzenMit.Text)

Text.Append(PdfTextExtractor.GetTextFromPage(reader, i)) StringBuilder text = new StringBuilder() įor (int i = 1 i <= reader.NumberOfPages i++) I found a way but I lost the whole information: using (PdfReader reader = new PdfReader(path)) I would like to keep the design of the content.

I want to find a Text in a static PDF-File and replace this text with another text. I' ve been searching the Internet for 2 Weeks and found some interesting solutions for my Problem, but nothing seems to give me the answer.
