ActionScript 3.0 :: Resize Object To Hexagon Form (Not Square)

I developed so far, a function to resize objects (images, shapes) and center them inside a hexagone clip (similar to the bees hexgagon cells).

function imageResizer (b, maxW:Number, maxH:Number) {
var r:Number;
r = b.height / b.width;
if (b.width > maxW) {
b.width = maxW;
b.height = Math.round(b.width * r);
} if (b.height > maxH) {
b.height = maxH;
b.width = Math.round(b.height / r);
}}

Symptoms: The function resizes the object being passed to it, but, there's still some room to fill inside the square, but now it's empty! is there any solution to resize the objects with max width/height and still be able to fill the whole area of the hexagone resizes.
