This came up a while ago. If you're happy with a solution that includes some
blank space (otherwise your regions can't be rectangular), try this code (it
includes some test code so you can just throw it into a movie with a
movieclip linked as 'square' and run to see the effect). I don't recall who
else it was that refined this code with me, so apologies for not giving due
credit:
function computeLargestSquareSizeAndLayout(width:Number, height:Number,
Nsquares:Number):Object {
if (width<height) {
var cols:Number = 1;
var rows:Number = Math.floor(height/width);
} else {
var rows:Number = 1;
var cols:Number = Math.floor(width/height);
}
//var cols:Number = 1;
//var rows:Number = 1;
var swidth:Number = width;
var sheight:Number = height;
var next_swidth:Number = width/(cols+1);
var next_sheight:Number = height/(rows+1);
while (true) {
if (cols*rows>=Nsquares) {
var squareSize:Number = Math.min(swidth,
sheight);
var posArray = [];
var count = 0;
for (var j = 0; j<rows; j++) {
ypos = j*squareSize;
for (var k = 0; k<cols; k++) {
xpos = k*squareSize;
if (count<Nsquares) {
posArray.push({x:xpos,
y:ypos});
count++;
}
}
}
return {squareSize:squareSize, cols:cols,
rows:rows, number:Nsquares, layout:posArray};
}
if (next_swidth>=next_sheight) {
cols++;
swidth = next_swidth;
next_swidth = width/(cols+1);
} else {
rows++;
sheight = next_sheight;
next_sheight = height/(rows+1);
}
}
}
function drawLayout(lobj) {
var holder = this.createEmptyMovieClip("holder", 1);
var squareSize = lobj.squareSize;
var cols = lobj.cols;
var rows = lobj.rows;
var number = lobj.number;
var layout = lobj.layout;
for (var j = 0; j<number; j++) {
var sqr = holder.attachMovie("square", "square"+j, j+1);
sqr._x = layout[j].x;
sqr._y = layout[j].y;
sqr._xscale = sqr._yscale=squareSize;
}
}
n=0
iterate=function(){
drawLayout(computeLargestSquareSizeAndLayout(640, 480, n++));
}
onEnterFrame=iterate
