Extract Arabic Text From Pdf document

Aug 30 2021 1:51 PM

I am trying to make a program which extracts the text from a PDF document PDF documents contain ARABIC text written by different types of FONT

when I extract the text it works with some files and others not it gives me ambiguous Text

I am using c # and Itext7 to make this program

please show me the methodology to do this with some examples

thank you
 

 

My code :

 

 StringBuilder processed = new StringBuilder();
            


            var src = "d:\\text06.pdf";
            var pdfDocument = new PdfDocument(new PdfReader(src));
            var strategy = new LocationTextExtractionStrategy();

            for (int i = 1; i <= pdfDocument.GetNumberOfPages(); i++)
            {
                PdfPage page = pdfDocument.GetPage(i);
                PdfDictionary fontResources = page.GetResources().GetResource(PdfName.Font);
                //foreach (PdfObject font in fontResources.Values(true))
                //{

                   // if (font is PdfDictionary)
                    //    fontResources.Put(PdfName.Encoding, PdfName.IdentityH);
               // }

                string output = PdfTextExtractor.GetTextFromPage(page);
                processed.Append(output);
            }
            string[] lines = Regex.Split(processed.ToString(), "\n");

            List<String> Converted_Lines = new List<string>();
            foreach (string  s in lines)
            {
                string converted_string = Inverse(s);
                Converted_Lines.Add(converted_string);
            }

            textBox1.Text = String.Join(Environment.NewLine, Converted_Lines);
