flash actionscript: Dear Forum

I'm looking for a way to get rgb values (Hex) of pixels in a bitmapData
rounded to the next closest websafe color.

Any ideas? Is this already built in flash? are there any Algortithms out
there?

thanks

pass your bmp to webSafeBMPF and it will color it websafe:





function webSafeBMPF(bmp) {
for (var x = 1; x<=Math.round(bmp.width); x++) {
for (var y = 1; y<=Math.round(bmp.height); y++) {
bmp.setPixel(x, y, "0x"+webSafeColorF(bmp.getPixel(x, y)));
}
}
}
function webSafeColorF(col) {
newCol = "";
for (var j = 2; j>=0; j--) {
tempCol = (col >> (j*8) & 0xFF);
if (tempCol%51<25) {
tempCol = tempCol-tempCol%51;
} else {
tempCol = tempCol+(51-tempCol%51);
}
while (tempCol.toString(16).length != 2) {
tempCol = "0"+tempCol;
}
newCol += tempCol.toString(16);
}
return newCol;
}

Here's how I would do it... you would use something like myBitmap.webSafe();

import flash.display.BitmapData;
import flash.geom.Point;
BitmapData.prototype.webSafe = function() {
var r:Array = new Array(256);
var g:Array = new Array(256);
var b:Array = new Array(256);
for (var i = 0; i<=255; i++) {
var v = Math.round(i/51)*51;
r[i] = v << 16;
g[i] = v << 8;
b[i] = v << 0;
}
this.paletteMap(this, this.rectangle, new Point(0, 0), r, g, b, null);
};

excellent! thanks guys...
