The image i created was an 8 bit image with a single component, you need to set
grids SetNumberOfScalarComponents 3
then set each of the scalar components within the loop (which should be the rgb values making your color) so for red;
grids SetScalarComponentFromFloat $i $p 0 0 255
grids SetScalarComponentFromFloat $i $p 0 1 0
grids SetScalarComponentFromFloat $i $p 0 2 0
this may work. an alternate solution would be to use a lookup table on your the single component image mapping color to value.
The data value of 0 corresponds to black, and I guess
255 will correspond to white.
How can I set this up, so that I can specify r g b color values, and
display red (255 0 0)?
