clone (DisplacementMapFilter.clone method)
public clone() : DisplacementMapFilter
Returns a copy of this filter object.
Availability: ActionScript 1.0; Flash Player 8
Returns
flash.filters.DisplacementMapFilter - A new DisplacementMapFilter instance with all
the same properties as the original one.
Example
The following example creates three DisplacementMapFilter objects and compares them:
filter_1 is created by using the DisplacementMapFilter constructor; filter_2 is created
by setting it equal to
filter_1; and clonedFilter is created by cloning filter_1. Notice
that although
filter_2 evaluates as being equal to filter_1, clonedFilter, even though it
contains the same values as
filter_1, does not.
