Nope, it is not...
the images that seems to break the application is 1500x1500.. while other
(smaller) images around 550x450 seem to work fine
quick overview:
A.) contentContainer
B.) |---------faceContainer
C.) |----------------------lineContainer (where I drawmy
lineTo() shape to be used as the base of my invertedMask function)
D.) |----------------------maskContainer (where the actual
invertedMask is created with the function I provided/am using)
E.) |----------------------centeredContainer (where the image
is loaded into)
faceContainer X/Y is centered is the absolute middle of the display area
all child clips of faceContainer (clips C-E above) are then off set by height &
width /2.. so that when I scale or rotate faceContainer.. all child clips
scale from the 'center'..
when I load in ANY image.. I check its height..and if bigger than my display
area.. I scale it down...
again this works fine is I load in a smaller image...
the only code is 1 (one) function...... (13 lines only) ........that breaks
when the image loaded is over a certain size (I believe sets the X/Y to a
negative number, beyond zero)
this is the function in question:
INVERSED MASK: ( mc = contentContainer.faceContainer.lineContainer)
//--------------------- [reverse mask code] --------------------- //
function inverseMask(mc:MovieClip) {
contentContainer.faceContainer.centeredContainer.cacheAsBitmap = true;
var _BMP:BitmapData = new
BitmapData(contentContainer.faceContainer.centeredContainer._width,
contentContainer.faceContainer.centeredContainer._height, true, 0xFFFFFFFF);
var invert:ColorTransform = new ColorTransform(0, 0, 0, 1);
var matrix:Matrix = new Matrix();
matrix.translate(0, 0);
//matrix.translate(mc._x, mc._y); //doesnt work
//matrix.translate(contentContainer.faceContainer.centeredContainer._x,
contentContainer.faceContainer.centeredContainer._y); //doesnt work
//matrix.identity();
//matrix.scale(contentContainer.faceContainer.centeredContainer._xscale,
contentContainer.faceContainer.centeredContainer._yscale);
_BMP.draw(mc, matrix, invert);
_BMP.threshold(_BMP, new Rectangle(0, 0, Stage.width, Stage.height), new
Point(0, 0), "<", 0xFFFFFFFF, 0x00FF0000);
var BMP:BitmapData = _BMP.clone();
var maskMC:MovieClip =
contentContainer.faceContainer.maskContainer.createEmptyMovieClip("invertedMask",
contentContainer.faceContainer.maskContainer.getNextHighestDepth());
maskMC.attachBitmap(BMP,
contentContainer.faceContainer.maskContainer.getNextHighestDepth());
maskMC.cacheAsBitmap = true;
mc._visible = false;
return maskMC;
}
thanks to anyone that even point me in the right direction on debugging...

I can't go through all of your info, but just off the top of my head what
is the size of the image you are trying to load? Is it larger than the 2880
x 2880 pixel limit?
