Jared, the 1x1 trick doesn't really work that well in Flash as you may have
already found out. I was using that myself for a project until I learned
that for some images it was pretty far off. So, I went to a more traditional
method - getting the average color of each pixel in the image, which
actually is faster than you might think. Here's the method I am using:
private function averageRGB( source:BitmapData ):uint
{
var red:Number = 0;
var green:Number = 0;
var blue:Number = 0;
var count:int = 0;
var pixel:Number;
for (var x:int = 0; x < source.width; x++)
{
for (var y:int = 0; y < source.height; y++)
{
pixel = source.getPixel(x, y);
red += pixel >> 16 & 0xFF;
green += pixel >> 8 & 0xFF;
blue += pixel & 0xFF;
count++;
}
}
red /= count;
green /= count;
blue /= count;
return red << 16 | green << 8 | blue;
}
