In this tip, we will see how to convert RichView documents to PDF using eDocEngine VCL. Here are the steps:

1. Drop TRichViewEdit, TRVPrint, and TRVStyle components from RichView palette on a Delphi form application.
2. Connect RichViewEdit1.Style property to RVStyle1.
3. From eDocEngine Additionals tab, add TgtRichViewInterface interface to the form.
4. From eDocEngine tab, add TgtPDFEngine component to the form.
5. To connect Gnostice RichView Interface to the eDocEngine component:
   1. On the form, select gtRichViewInterface1.
   2. In the Properties window, select the Engine property and click the drop-down icon to select the PDF engine gtPDFEngine1.
6. In the code window, add the following code:

   procedure TForm1.Button1Click(Sender: TObject);
   begin
     // Load the input .RVF file into the 
     // TRichViewEdit component
     RichViewEdit1.InsertRVFFromFileEd('C:\Input.rvf');
   
     // Assign the TRichViewEdit component as the 
     // source for the TRVPrint object.
     RVPrint1.AssignSource(RichViewEdit1);
   
     // Apply formatting for all pages
     RVPrint1.FormatPages(rvdoALL);
   
     // Specify output PDF filename
     gtPDFEngine1.FileName := 'Output.pdf';
   
     // Export the RVF file to PDF
     gtRichViewInterface1.RenderDocument(RVPrint1, False);
   end;
