Find the field names of inputtable form fields in a PDF document? I have an editable PDF form that I'm trying to automate the entry of form fields into using python. In order to do this I must know the "names" of the form fields in the FDF data to input. See question for background: How can I auto-populate a PDF form in Django/Python? I don't need to find the names programaticaly from the PDF necessarily, just need to know what they are so if this is possible in Preview/Adobe/etc. PDF readers/editors that is sufficient.

I need to have the ability to convert and merge various documents into a single Pdf. The documents could be of varying types, such as Word, Open Office, Images, Text, Web pages (by URL) and the PDF would usually consist of 2-3 documents. At the moment, we are using BCL Technologies easyPDF with Microsoft Office installed onto the Server. This handles most documents but we haven't had it doing Open Office ones yet. We currently produce around 100-1000 of these PDF's per day. The reason I am asking the question is that performance is a key issue. The PDF is generated for users on the fly and so

I'm investigating how one can combine multiple PDF's into a single PDF. I'm looking for a library that is as reliable and robust as possible. Preferable a library that can preserve bookmarks . Ghostscript can concat where the bookmarks are preserved, but I experienced trouble where it in one case failed to generate any output.pdf. gs -q -sPAPERSIZE=letter -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sOutputFile=output.pdf document1.pdf document2.pdf document3.pdf GPL Ghostscript 8.54: Unrecoverable error, exit code 1 GPL Ghostscript 8.54: ERROR: A pdfmark destination page 36 points beyond the last

In my Objective-C iOS app I'm creating PDF files using the code: UIGraphicsPDFRenderer* renderer = [[UIGraphicsPDFRenderer alloc] initWithBounds:pdfSize]; NSData* outputPdfData = [renderer PDFDataWithActions:^(UIGraphicsPDFRendererContext * _Nonnull context) { [context beginPage]; // draw operations here }]; The ultimate aim is to then send this PDF to an AirPrinter. However, due to the printer hardware we're using it looks like it is going to be necessary to embed in to the PDF an ICC colour profile (possibly CMYK) to ensure accurate colour reproduction. I've done such operations before in

I struggled to converted SVG Files into PDF using JSPDF.

Hi I am creating PDF using itextsharp. Now my requirement is to add more text to the existing pdf. Is it possible if so then how can I do that? Thanks Dipa Yes, with certain limitations. It is difficult, but not impossible, to determine what is already on an existing page. If all you want to do is add "page X of Y" to the bottom left corner of all your pages, that's easy . PdfReader reader = new PdfReader( inPath ); PdfStamper stamper = new PdfStamper( reader, new FileOutputStream( outPath ) ); BaseFont font = BaseFont.createFont(); // Helvetica, WinAnsiEncoding for (int i = 0; i < reader
