nice work Mario! Always wanted to know how colorblind people see images... thanks a lot !

Very Nice! I can't to try this out! I really think the applyColorDeficiency() method could be promising.

Looking good Mario.
Will be making use of your class....
thnx!

Keep up the good work!

:) I re-wrote this last week for our use.

Can you send me a mail bud?

Great work! I will add it to my favorite util classes. I just get four Errors in the setChannels method. All four errors says that i can not combine Number and Boolean or i can not use Boolean here.
Any idea how to solve the problem?

Strange - which tool gives you that error? I'm using Flex Builder and it does neither give me errors nor warnings with this class.

That's strange. FDT 3 gave the error.

Ah okay - might be that FDT is too strict here. Maybe Nico should have a look at it.

I could solve the problem when i set paranthesis around each conditional operators. I hope, it will not affect the operation:

public function setChannels( r : int = 1, g : int = 2, b : int = 4, a : int = 8) : void
{
var rf : Number = ((((((r & 1) == 1)) ? 1 : 0 + ((((r & 2) == 2)) ? 1 : 0)) + ((((r & 4) == 4)) ? 1 : 0)) + ((((r & 8) == 8)) ? 1 : 0));
if (rf > 0)
{
rf = (1 / rf);
}

var gf : Number = ((((((g & 1) == 1)) ? 1 : 0 + ((((g & 2) == 2)) ? 1 : 0)) + ((((g & 4) == 4)) ? 1 : 0)) + ((((g & 8) == 8)) ? 1 : 0));
if (gf > 0)
{
gf = (1 / gf);
}

var bf : Number = ((((((b & 1) == 1)) ? 1 : 0 + ((((b & 2) == 2)) ? 1 : 0)) + ((((b & 4) == 4)) ? 1 : 0)) + ((((b & 8) == 8)) ? 1 : 0));
if (bf > 0)
{
bf = (1 / bf);
}

var af : Number = ((((((a & 1) == 1)) ? 1 : 0 + ((((a & 2) == 2)) ? 1 : 0)) + ((((a & 4) == 4)) ? 1 : 0)) + ((((a & 8) == 8)) ? 1 : 0));
if (af > 0)
{
af = (1 / af);
}

concat([(((r & 1) == 1)) ? rf : 0, (((r & 2) == 2)) ? rf : 0, (((r & 4) == 4)) ? rf : 0, (((r & 8) == 8)) ? rf : 0, 0, (((g & 1) == 1)) ? gf : 0, (((g & 2) == 2)) ? gf : 0, (((g & 4) == 4)) ? gf : 0, (((g & 8) == 8)) ? gf : 0, 0, (((b & 1) == 1)) ? bf : 0, (((b & 2) == 2)) ? bf : 0, (((b & 4) == 4)) ? bf : 0, (((b & 8) == 8)) ? bf : 0, 0, (((a & 1) == 1)) ? af : 0, (((a & 2) == 2)) ? af : 0, (((a & 4) == 4)) ? af : 0, (((a & 8) == 8)) ? af : 0, 0]);
}

Ah thanks! I guess I should adjust my code as well. so it looks like this is a case of operator precedence - the question remains which tool has got it wrong. Since the code works fine without the paranthesis I guess it's FDT that needs to be adjusted.

Thanks heaps! I used the old AS2 as a base for my own AS3 version, so it's nice to see a real PRO conversion here. Thanks again for all your hard work and sharingness.
