I am not sure as to what am I doing wrong. Using(FdfReader fdfReader = new FdfReader(fdfFileNameAndPath))ĪcroFields pdfForm = pdfStamper.AcroFields Using(PdfStamper pdfStamper = new PdfStamper(pdfReader, pdfFlat)) Using (PdfReader pdfReader = new PdfReader(templateLocation)) The following is the code that I am using but when I open the newly saved file, it says that the file is damaged and could not be repaired: using (MemoryStream pdfFlat = new MemoryStream()) So, then I decide to use iTextsharp, read the PDFTemaplate file, read the FDF file and get the data from there, and create another PDF file and save it along with the data. But I can't save this file using the File menu, as it says this file will be saved without the data. string theValues int theLastID Convert.ToInt32(theFDF. Now, when try and double click on the FDF, it open the Adober Acrobat Reader and displays the PDFTemplate with the data filled in. items there are in the FDF file and prepare to iterate through them. Also, this FDF contains the file path for the PDFTemaplte also, so that on opening, it knows which PDF to use. Now I generate this FDF file pro-grammatically, which in turn contain all the field names required for the PDFTemplate to be filled in. I have a PDFTemplate.pdf which serves as a template and has placeholders (or fields). No, I can't find the example any more.I am trying to save a PDF file by saving the data from the FDF into a PDFTemplate, in my WPF application. (3) I have even seen PDFs where the creator program went long stretches to make this almost impossible, by putting each glyph independently and randomly in the page, to make tampering with it very difficult. and then use scripting, manual editing, whatever to massage it up. However, you can try to convert the information to things more manageable with, for example, pdftotext(4): 1 % pdftotext Untitled1.pdf cat Untitled1.txt So no, you never think that going back from PDF to your data should be possible(3). You can't know because the info is simply not there. The number 3 could be a 2.95 rounded up, even. There is no way for a computer program to say if it's two rows by three columns or two rows by two columns containing spaces in it(2). ![]() It is basically(1) a series of instructions of the kind of "put the word hello at position x,y in the page". No, it is not reasonable to expect that any program should be able to read a PDF it generated, not any more than expecting a printer to be able to churn back a sheet it had just printed and giving you back your document. I wish Base could decode a PDF file that Base created So, select PDF file that you want to compress on this compress PDF to 200kb tool. If you want to get only whole words, use the -C 0 option. You can compress PDF to 200kb by using this free online compressor tool. I will complete the solution with pdfgrep tomorrow but if you want to try it for yourself, here is the command: pdfgrep 'CompanyName|CountryOrRegion|EmailAddress' filled_form-submit_format_fdf.pdf *Note: You can also use Libre Base to export a blank form as XML or HTML, but I don't know how to input data into those files nor import that data back into Base. pdftk filled_form-submit_format_fdf.pdf generate_fdf output filled_form.fdf.pdftk filled_form-submit_format_fdf.pdf dump_data_fields output filled_form.csv.An FDF file contains data collected from the form fields in a PDF document. ![]() ![]()
