[vtkusers] vtkImageActor for 10 bit displays?

[Jesús Spí­nola]

Hi,

I am also interested on this topic.

My question is, how can you achieve 10-bit display when vtkImageActor
requires data to be of unsigned char type? (
http://www.vtk.org/doc/release/5.6/html/a00819.html) This means data is cut
down to 8-bit, so the resolution is already lost though your vtkImageData
were of short  type (2 bytes).
