HOW TO: Get names of fonts in PDF file

The PDFDoument class allows parsing multiple different objects using the ParsePage() method, including fonts. After parsing the PDF document, the fonts will be populated in the PDFDocumentPage.Fonts collection as PDFFont objects. In case the page doesn’t have any fonts, the collection will be initialized empty. Note that you’ll need to specify PDFParsePagesOptions.Fonts in the ‘options’ parameter of the ParsePages() method to be able to parse fonts. The code looks like this:

string _inputPDF = @"C:\Users\Public\Documents\LEADTOOLS Images\Leadtools.pdf";
string _fontsPDF = @"C:\Users\Public\Documents\LEADTOOLS Images\LeadtoolsPDF_Fonts.txt";

// Open the document
using (PDFDocument _MyDocument = new PDFDocument(_inputPDF))
{
   // Parse the fonts for all pages
   PDFParsePagesOptions _MyOptions = PDFParsePagesOptions.Objects | PDFParsePagesOptions.Fonts;
   _MyDocument.ParsePages(_MyOptions, 1, -1);

   // Save the results to the text file for examining
   using (StreamWriter writer = File.CreateText(_fontsPDF))
   {
      foreach (PDFDocumentPage _MyPage in _MyDocument.Pages)
      {
         writer.WriteLine("Page {0}", _MyPage.PageNumber);
         IList<PDFFont> _PDFfonts = _MyPage.Fonts;
         writer.WriteLine("Fonts: {0}", _PDFfonts.Count);
         foreach (PDFFont font in _PDFfonts)
         {
            writer.WriteLine("FaceName: " + font.FaceName);
            writer.WriteLine("------");
         }
      }
   }
}
