Subject: Re: [Flashcoders] Swap 8 bit palettes
If I'm not getting this wrong, this simple function should do the work
(assuming you have your palette defined as an array)
I've tested in Flash 8 (that's why I'm using Number's instead of int's;
for
AS 3.0 I'd go with int's)
function createPaletteData(palette:Array):Object {
var len:Number = palette.length;
var r:Array = [];
var g:Array = [];
var b:Array = [];
var cur:Number;
for(var i:Number = 0;i<len;i++) {
cur = palette[i];
r[i] = cur >> 16;
g[i] = (cur & 0x00ff00) >> 8;
b[i] = (cur & 0x0000ff);
}
return {r:r,g:g,b:b};
}
var test_arr:Array = [0xff005c,0xfc1236,0x001200,0x180055];
var oArrays:Object = createPaletteData(test_arr);
trace(oArrays.r);
trace(oArrays.g);
trace(oArrays.b);

Has anyone by any chance made a function to dump an 8 bit palette to the
arrays the paletteMap function is asking for? :)
I guess the alternative is to create an image that holds the palette as
pixels in rows, and then use getpixel to pull one rgb at a time to
populate
the arrays.
