scalars to color mapping

[Dingrong Yi]

Hi there,

I noticed one problem of vtk on scalars to color mapping. I have a
Structured data sets, with dimensions 63 151 164. I displayed with color
table hue range set to 0 0.667, or 0 1 , or 0.667  0. No matter what color
range, the displayed image is just gray scale image (indeed, my value
range is set to cnstant 1 1). With the same CPP code, several small volume
image (16 16 7)  got correct colors.  Is that true that VTK color mapping
works incorrectly for bigger volume images ? 

Any body has the same experience ? 

Thanks.

Dingrong
