From download to your first PDF

1. Install Delphi / Object Pascal

// add include\ to the unit search path
uses LumasPdfOO;

2. Write a PDF

The smallest complete program: create the document, write to it, close it.

var
  Pdf: TLumasPdf;
begin
  Pdf := TLumasPdf.Create;
  try
    Pdf.CreatePDF('hello.pdf');
    Pdf.Append;
    Pdf.SetFont('Helvetica', fsNone, 24.0, True, cp1252);
    Pdf.WriteFText(taCenter, 'Hello from LumasPDF');
    Pdf.EndPage;
    Pdf.CloseFile;
  finally
    Pdf.Free;
  end;
end;
