GdPicture Imaging

I try to display a multi-page PDF and have set ContinousViewMode=true. Still, I can only scroll through page 1. I can switch to next page by right-clicking and selecting "Pages / Frames -> Goto next".

Code: Select all

   WideString ws=L"t:\\scuba.pdf";
   WCHAR *sz = ws.c_bstr();

   try
   {
      BSTR bstr = SysAllocString(sz);
      GdViewer1->ContinuousViewMode=true;
      GdViewer1->DisplayFromFile(bstr);
      SysFreeString(bstr);
   }
   catch(...)
   {
      ShowMessage("EXCEPTION");
   }


Am I missing something?

How can I make the control behave like Acrobat Reader so you can scroll through the entire PDF using pgup/pgdn or mouse scroll wheel?

Hi,

ContinousViewMode have no effect on page scrolling behavior. There is no way to move through next/previous page using scroll-bars.

Kind regards,

Loïc

To view other pages I use

GdViewer.DisplayFiresFrame()
GdViewer.DisplayNextFrame()
GdViewer.DisplayjPreviousFrame()
GdViewer.DisplayLastFrame()

or

GdViewer.DisplayFrame(FrameNumber)

Hope this will help

As you've seen you cannot emulate Adobe Readers continuous page mode.

You can, however, use the Mouse Wheel to scroll between pages when you have ContinuousViewMode set to True.
