# To subscribers of the xforms list from Michal Szymanski <msz@bulge.astrouw.edu.pl> :

Hello,

I've read the chapter about images in XForms' manual, but apparently
either I missed it or it is not there:

If I try to display GRAY16 image (e.g. read from a 16-bit FITS file)
in a PseudoColor visual (e.g. in a canvas window), what kind
of colormap is used? Does the display routine change the colormap?
Should the user prepare it manually? Can the user control how
many grey levels are used?

thanks in advance for any hints,

regards, Michal.
