[Paraview] COLOR_SCALAR

[Barosan, I.]

I would like to use unsigned char values which are directly mapped to
colors. I've created this vtk file that contains 25 points and each
point has his own color specified with COLOR_SCALARS. If I read this
file in ParaView2.2  the colors assigned to the points are wrong. The
results look good when I use another vtk package (MayaVi). Is that a bug
in ParaView or I am doing something wrong ? Any help will be
appreciated,

 

 

Regards,
