Method makeDropShadowOnly

shared/java/ImageFilter.java:353–362

Create a filter that renders a drop shadow, in exactly the same manner as makeDropShadow, except that the resulting image does not include the input content. This allows the shadow and input to be composed by a filter DAG in a more flexible manner. @param dx The X offset of the shadow @par
