>>>What i want to do is modify the image with
color tint or some other effect i can obtain
onscreen (but cannot understand clearly since
the documentation is quite mute on these
calculations...) You can easily see by yourself
: make a canvas, draw an image in its backdrop,
draw something in its backdrop.mask (try a plain
light color, definitely not grey) and admire the
effect. Nobody did this before ? I can't believe
this!

you're doing is called "relying on undocumented
behavior" and it is a bad thing, because (1) the
undocumented behavior is likely to change with
different versions of RB, and (2) it probably
also varies with the operating system you're
running on.
> Masks should always be grayscale.
and 3. you will cry when a change will
occured (because it always occured at one time
in the future)...
Certainly, but if this becomes a documented feature in RB6, Few will cry.
I am experimenting in colors and viewing, could
you point me to some literature, examples and
RB-made softwares ?
Thanks again!
