Question

i want to generate a pdf with itext 7,but some wrong happens to us:

com.itextpdf.kernel.PdfException: Pdf indirect object belongs to other PDF document. Copy         


        

Answer 1

This is how i solved the issue.

1. Created an DocumentUtil class

2. Add a static method

   public class DocumentUtils {    
       public static PdfFont setFont() throws Exception {
               return PdfFontFactory.createFont(StandardFonts.TIMES_ROMAN);
       }
   }
   

3. Use the font like:

   PDfFont font = DocumentUtil.setFont();
