[vtkusers] precision of SPACING

[Nico Schlömer]

Hi,

is there any way to tell VTK to store the SPACING (as in legacy VTK
files) in higher precision? As far as I can see, this is limited to
seven, eight significant digits. It's not that I need 15 digits for
plotting but for reading and working with it I do. An easy workaround
would of course be to to the values separately in a field.

XML-based VTI, for example, stores 15 digits. Is that something one can rely on?

Cheers,
Nico
