# static sourceRect(layer, timeopt, includeExtentsopt, includeMasksopt) → {Array.<float>}

Returns the bounds of the layer in local coordinates, like the sourceRectAtTime() function does in expressions, but can also include masks.

Parameters:

Name	Type	Attributes	Default	Description
`layer`	`Layer`			The layer
`time`	`float`	<optional>		The time at which to get the bounds, the current time by default
`includeExtents`	`Boolean`	<optional>	true	Includes the extents (strokes, accents...)
`includeMasks`	`Boolean`	<optional>	true	Includes the masks

View Source DuAEF.jsxinc, line 30591

Returns:

The bounds [top, left, width, height]

Type: Array.<float>

# static stack(layers)

Stacks the layers in the timeline according to their order in the given array/DuList

Parameters:

Name	Type	Description
`layers`	`LayerCollection` \| `Array.<Layer>` \| `DuList.<Layer>`	The layers to stack

# static toggleEditMode(layer)

(Un)parent the children of the layer.< br/> When children are unparented, an effect is added and the name of the layer is changed to show the "edit mode" is enabled.
When toggled again, the effect is removed, and the name is restored.

Parameters:

Name	Type	Description
`layer`	`Layer`	The layer to toggle.

# static translate(layer, offset, worldopt)

Sets the new coordinates of the layer to translate it by offset.

Parameters:

Name	Type	Attributes	Default	Description
`layer`	`Layer`			The layer to move
`offset`	`Array.<float>`			The value of the translation. A two or three dimensionnal array.
`world`	`boolean`	<optional>	false	Set to true to offset in world coordinates.
