[vtkusers] Non-square pixels and SetPixelAspect()

[John Platt]

Hi All,

 

Maybe it's because I'm an engineer but I expected a square in world
coordinates to be displayed as a square on my monitor.

 

I measured a 700 x 700 window as 231 x 246 mm and concluded the pixels
are not square but have an aspect ratio of approximately 0.94 : 1. Using
vtkViewPort::SetPixelAspect( 0.94, 1) and the comments in bug #626, the
view is now square.

 

Does anyone know how to get the pixel aspect ratio on Win32 without
using a rule?

 

Many thanks

 

John.
