问题 I have to update fields in pdf dynamically from Delphi code. Is it possible to classify a textbox from a checkbox in pdf file? If so, how to update from Delphi code? Is there any third party library available under GNU license for that matter? 回答1: If you can figure out how to run PHP from within Delphi (?), there is another tool TCPDF which is LGPL licensed close to GNU licensing. If you can figure out how to call Java from Delphi, then you could try PDFBox (an Apache project so the licence

问题 Right now I have a form template that has some fields that are prefilled from a database using the iTextSharp library. Users will then fill in the rest of the fields and save the filled out forms. I'll then extract the data and put it in the database. Currently I am able to create the PDFs and they are pre-filling just fine. I'm even able to edit and save them in Adobe Reader on my computer. However I'm finding when anyone else opens those same files, they're not allowed to save the forms.

问题 I'm creating "labels" and textboxes and checkboxes using iTextSharp, but my attempts to derive from that code to create buttons has not yet been successful.

问题 I am using Apache PDFBox to read a fillable PDF form and fill the fields based on some data. I am using the below code (as per suggestions from other SO answers) to get the default Appearance String and changing it (as you can see below, I am changing the font size from 10 to 12 if the field name is "Field1". How do I bold the field? Any documentation on what order the /Helv 10 Tf 0 g are arranged? What I need to set to bold the field? If I understand right, there are 14 basic fonts that I

问题 I am building a webapp that will display PDFs. The PDFs have fillable forms. Instead of making the user save the form, and then re-upload it to the webapp, the idea is to adapt the PDF such that it can POST itself (when the user clicks) from inside the browser to some HTTPS endpoint when the user is done. Is this doable? If so, how? If not, any suggestions? Thanks. 回答1: Yes, there is an option (action) that allows pdfs to post themselves. The steps are as follows: List item Open Adobe Acrobat

问题 I'm trying to add choices to a List-field within a pdf form via C# and the itextsharp library. But i cant find a way to do this. The form already exists, i created it with Acrobat.

问题 In my previous SO question PDFBox 1.8.10: Fill and Sign PDF produces invalid signatures I explained, how I failed to fill and afterwards sign a PDF-Document, using PDFBox 1.8.10. After this got sorted out with some kind help, I now continue to work on the same topic. Starting with doc_v2.pdf (links to the file are below!), I fill and sign it, resulting in doc_v2_fillsigned.pdf (doing it in one go, saving it incrementally). Again I open the edited document (using again PDFBox) and try to fill
