Thanks to both. Now I understand it. But I still have the same problem
because I only have a matrix of, for example, 100x100 values with data
from -32000 to 32000 (is that Long, Int...? I don't know...). Should I
change the type data before draw it?
Imagine that a guy send to you a 100x100 matrix with data from -32000 to
32000 values. How will you show it in the screen? I don't need show it in
colors, only in grey levels.
