I appreciate the help. Sorry guys, I am not an avid Photoshop or Javascript expert here in scripting.
I have tried your selection script and it errors out if I fill in the mask channel name. I have also tried just RGB and I get the same error:
Error: Illegal Argument
Tried:
selection_from_channel("RGB");
//selection_from_channel("Msk ");
and
selection_from_channel("HL Mask"); <--- Name of the Layer Mask Channel
//selection_from_channel("Msk ");

It seems that a layer mask and a layers bounds are the same somwtimes. When the layer actual content smaller then then layers mask selection boynds. The layers bounds is the layer pixels bounds.

Here is a script to fit a layer to the current selection the is a selection bounds you can use. Also add a layer mask to shape the layer to the selection. Slection Bounds was broken in CS2 I had to use other means back than.
var startRulerUnits = app.preferences.rulerUnits;
app.preferences.rulerUnits = Units.PIXELS;
if (app.activeDocument.activeLayer.kind == LayerKind.NORMAL || app.activeDocument.activeLayer.kind == LayerKind.SMARTOBJECT && hasLayerMask()) { deleteLayerMask ();}
var LB = activeDocument.selection.bounds;
var width = LB[2]-LB[0];
var height = LB[3]-LB[1];
var IB = activeDocument.activeLayer.bounds;
var dwidth = IB[2]-IB[0];
var dheight = IB[3]-IB[1];
var ratio = height/width;
var dratio = dheight/dwidth;
if (dratio>ratio) { // layer's Aspect Ratio less the Canvas area Aspect Ratio
var percentageChange = ((width/dwidth)*100); // Resize to canvas area width
app.activeDocument.activeLayer.resize(percentageChange,percentageChange,AnchorPosition.MIDDLECENTER);
}
else {
var percentageChange = ((height/dheight)*100); // resize to canvas area height
app.activeDocument.activeLayer.resize(percentageChange,percentageChange,AnchorPosition.MIDDLECENTER);
}
align('AdCH'); // align to horizontal centers
align('AdCV'); // align to vertical centers
addLayermask(); // add layer mask to mask off excess
app.preferences.rulerUnits = startRulerUnits; // restore ruler units

Here is how I got the Selection bounds in CS2
Its the layer content that is important if you have a layer mask the has bounds less then the camvas size it will make the layer bound less that canvas size. A layer may also have a bounds smaller then a layer mask slelection bounds. The screen capture I posted show this if you read the Script alert messages you should see this. The middle image has a reveal all layet mask its selection boynds is canvas size. The layers content the image is less then canvas size.
