Sigh...
I know you have been working on this project for a long
time, but I think you are still doing nearly everything
wrong. :-)
The volume array you are building doesn't have
any "color" associated with it. But, maybe you
are now at least building the volume array
correctly. Are the images, in fact, slices from
a volume?
If so, maybe you could use the code found here:

Just load your volume array in the place where
it says "Load the data."
Cheers,
David

Thank you for remembering! But I can view the output, control the
animation slice by slice and everything. Instead of a Black colored
image in my XOBJVIEW window, I would like to convert it into white
color. I just want to make a complementary image. Why would I need
color information from the image for this? I have the pixel values
where the maximum is 295. Instead of displaying this particular pixel
as a black colored pixel, can I assign a color for it to be displayed
in white color? Thank you for the help and tips!
