I use a program which generates three matrices for each time step. To
plot the data, I combine them into a single image by using the
COLOR_QUAN function
image=color_quan([[[mat1]],[[mat2]],[[mat3]]],3,red,green,bl ue,cube=6)
tvlct,red,green,blue
tv,image
and all it is OK. The problem arises when I want to change the colors
associated with the image. Imagine that I want to change the colors
(red,green,blue) to (white,grey,black) in order to get a suitable image
to print in a non color postscript printer. What have I to do? I have
tried by loading the color palette black-white (loadct,0) but I don't
get enough contrast. In other words, is possible to change the colors
RGB coming from COLOR_QUAN to another set of colors?
Thanks in advance.
RAFA.
