问题 Background: I have PDF's I am programmatically generating. I need to be able to send the PDF directly to a printer from the server (not through an intermediate application). At the moment I can do all of the above (generate PDF, send to printer), but because the fonts aren't embedded in the PDF the printer is doing font substitution.

问题 Let's say I've loaded a PDF file using iTextSharp: PdfStamper p = GetDocument(); AcroFields af = ps.AcroFields; How do I get a list of all field names on the document from af ? 回答1: AcroFields af = ps.AcroFields; foreach (var field in af.Fields) { Console.WriteLine("{0}, {1}", field.Key, field.Value); } 回答2: PdfReader pdfReader = new PdfReader("c:\\ABC.pdf"); string TempFilename = Path.GetTempFileName(); AcroFields pdfFormFields = pdfReader.AcroFields; foreach (KeyValuePair<string, AcroFields

问题 I am trying to use iTextSharp to read/modify PDF metadata. I figured out how to do it using pdfreader and pdfstamper. I was wondering if I could also read/modify additional metadata information like copyright information and few others within the XMP photoshop namespace.

I've read metadata like this: PdfReader reader = new PdfReader("HelloWorldNoMetadata.pdf"); string s

问题 I assume I need to flatten a XFA form in order to display properly on the UI of an application that uses Nuance's CSDK. When I process it now I get a generic message "Please Wait.... If this message is not eventually replaced..". Looking for some sample iTextSharp code to do this. 回答1: You didn't insert a code sample to show how you are currently flattening the XFA form.
