Re: [Flashcoders] Converting hex colour numbers back and forth
I usually don't use parseInt for this purpose I usually just cast it as a uint. i.e. uint(c); would work as well. glad you figured it out. - Taka On Tue, Feb 10, 2009 at 5:54 AM, ali drongo wrote: > Thanks everyone, Juan, you solved the final part of the puzzle and Muzak > thanks for your utility class it's very useful. > Cheers again! > Ali > > On Tue, Feb 10, 2009 at 1:13 PM, Muzak wrote: > >> Maybe this will help? >> http://muzakdeezign.com/flex3/flex3lib/ColorUtil.zip >> >> //docs >> >> http://muzakdeezign.com/flex3/flex3lib/docs/com/muzakdeezign/flex/utils/ColorUtil.html >> >> regards, >> Muzak >> >> - Original Message - From: "ali drongo" >> To: "Flash Coders List" >> Sent: Monday, February 09, 2009 6:26 PM >> Subject: [Flashcoders] Converting hex colour numbers back and forth >> >> >> Hi there, I'm saving a bunch of colours as a string then using this string >>> later to colour objects in the same way.

Re: [Flashcoders] Converting hex colour numbers back and forth
Hi Ali,
If you need to switch between different number systems, you can also
try this:
var myUint:uint = 0xff; // this is the colour red
trace (myUint.toString(16)); //will trace ff -- in hexadecimal
system;
trace (myUint.toString(2)); //will trace --
in binary system;
Hope this helps,
Sidney

You're asking parseInt to convert a string to an integer and telling
it the
string is an hexadecimal representation, when it's decimal,
according to
this line:
trace("string colour:"+c); // e.g. for red: 16711680
So try,
hexNum:Number = parseInt(c,10);
If you have a number, you don't need to worry about decimal /
hexadecimal.
It's just a number: you can have, say, the number 10, which would be
represented as "10" in decimal, "0xa" in hexadecimal, "1010" in
binary, etc,
but those are just a way to display a number. If you already have the
number, you don't need any extra step.
Hope this helps.

Thanks for your responses guys. I'm still stuck on this and I have
been
playing around a lot. I can get the number from the decimal format
to the
hex string but when I try to convert it to a hex number the colour is
incorrect.
Any advice much much appreciated, this is taking up lots of time.
Thanks:
public function colorIn(o:Object):void
{
trace("===");
var colA:Array = o.Colors.split(",");
colA.splice(0,1);
for ( var i:uint=1; i<=totSprites-1; i++ ) {
var c:String = colA[i];
trace("string colour:"+c); // e.g. for red: 16711680
//convert to decimal number
var tmpN:Number = Number(c);
trace("decimal:"+tmpN); // traces: 16711680
//convert to string of hex number
var hexStr:String = tmpN.toString(16);
trace("hexStr:"+hexStr); //traces: ff
//convert to hex number
var hexNum:Number = parseInt(c, 16);
trace("= = = = = = => hex number:"+hexNum); //traces in decimal

Hi there, I'm saving a bunch of colours as a string then using this
string
later to colour objects in the same way. Something is going wrong
though as
the colours I am getting back are not the same as the ones I put in.
If anyone could point out where I'm going wrong I'd be really
grateful,
I've
googled this and and have checked the help files and as far as I
can see
it's correct (though obviously it isn't!).
Here's my code, I've written comments next to the relevant lines:

private function clickHandler(e:MouseEvent):void
{
// passes hexValue from ColorPicker
colorThis(this.parent.parent["colorPick"].hexValue);

public function colorThis(c:String):void
{
//stores colour
currColor = Number("0x"+c);
var newColorTransform:ColorTransform =
this.transform.colorTransform;
newColorTransform.color = currColor;
this.transform.colorTransform = newColorTransform;
}

I haven't looked into it in detail, but I think you would want to use
parseInt( "0x" + c, 16 ) here.
If that doesn't fix it, try tracing the values throughout your
conversion and see where it breaks.
