[vtkusers] Displaying large images in a MFC/VTK application

[PHAM Quoc-Cuong 203899]

Dear vtk users,

I use a vtkImageViewer in a MFC/VTK application to display large images
(3000 x 2000) with some features such as scrolling and mouse interaction.
The interaction is managed with vtkInteractorStyleUser and the messages are
passed to vtk by WindowProc.

In my derived class CScrollView, I tried 2 ways to associate the render
window and the MFC view window:
A) with SetParentId(HWND) -> everything works fine with images of reasonable
size (< 1280 x 1024), but becomes incredibly slow in the case of large
images / or the application crashes depending on the graphics card,
B) with SetWindowId(HWND) -> the display of large images is ok, but I loose
the expected interactions (scrolling and wrong coordinates returned by
vtkInteractorStyle::OnMouseMove()).

Can anyone help me ?
Thanks,
