The <feDropShadow>
filter primitive creates a drop shadow of the input image. It is a shorthand filter, and is defined in terms of combinations of other filter primitives.
The result of the <feDropShadow>
filter is equivalent to the following:
<feGaussianBlur in="alpha-channel-of-feDropShadow-in" stdDeviation="stdDeviation-of-feDropShadow"/> <feOffset dx="dx-of-feDropShadow" dy="dy-of-feDropShadow" result="offsetblur"/> <feFlood flood-color="flood-color-of-feDropShadow" flood-opacity="flood-opacity-of-feDropShadow"/> <feComposite in2="offsetblur" operator="in"/> <feMerge> <feMergeNode/> <feMergeNode in="in-of-feDropShadow"/> </feMerge>
