I am a newbee but I am using very simple code. I am finding that with about half the PDF files I must render the first page a second time becuase the first time I get a blank page. This problem occurs with the QuickPDF manual too.

           QP.LoadFromFile('iSEDQuickPDF 5.11 Reference Guide.pdf');
           // This first one yields a blank page ???
           QP.RenderDocumentTofile(150, 1, 1, 6, 'Test.gif');
           // Check if blank (very small filesize) and re-render
           if _getfilesize('Test1.gif') < 8000 then
               QP.RenderDocumentTofile(150, 1, 1, 6, 'Test.gif');

          // All subsequent Rendering is good such as:
          QP.RenderDocumentTofile(150, 2, 2, 6, 'Test.gif');
             ...
          QP.RenderDocumentTofile(150, 25, 25, 6, 'Test.gif');

Any help is very appreciated,

Regards, John

Thanks for the suggestion. Using "SelectPage" before the call to Render solved the problem with the blank pages...
