Use

if(not(FindColorTolerance(params))) then
 //do stuff 
end;

if (NOT FindColorTolerance(.......)) then..

Not the other way around.. I've never seen Not If before :S

Lol I corrected myself within a minute or two after posting that.

why so many brackets?

if not FindColorTolerance(stuff) then

is much easier

why so many brackets? Simba Code:
[LEFT]if not FindColorTolerance(stuff) then
[/LEFT]

is much easier

Most coders use brackets to differentiate ambiguity.

What if I had like 20 functions embedded between brackets and-ing the results?

Example:


Result:= (not Meh and Not bleh and Not what and not this and not that);

well You'd probably want to do:


Result:= ((Not Meh) and (Not Bleh) and (Not What) and (Not this) and (Not That));

Also I used that many brackets because I'm too used to coding in C where the if statement MUST have brackets.


if (this)   //Without these brackets in the C Languages, it's not going to compile.
{
}
