What you need is an NSImage(Rep). Check their docs.
BOOL is a byte, incidentally (but you should not depend even on that, it's
abstract type to be "unknown" for good reasons).
(it's only for objects
to reference not for drawing) When I try to make a BOOL array like this
->
BOOL test[786432] /*1024 *768 ==786432*/ it crashes. I am guessing that I
am
going out of the local memory space? or something like that.
Hmmm, is it local or global? If former, it might be the reason -- I am not
sure of the stack space, but it is quite possible there's no a free M
there. Though, there should be no problem with a global M; if so, there
would be anotehr problem too.
