The <feDropShadow>
SVG filter primitive creates a drop shadow of the input image. It can only be used inside a <filter>
element.
Note: The drop shadow color and opacity can be changed by using the flood-color
and flood-opacity
presentation attributes.
Like other filter primitives, it handles color components in the linearRGB
color space by default. You can use color-interpolation-filters
to use sRGB
instead.
dx
This attribute defines the x offset of the drop shadow. Value type: <number>; Default value: 2
; Animatable: yes
dy
This attribute defines the y offset of the drop shadow. Value type: <number>; Default value: 2
; Animatable: yes
stdDeviation
This attribute defines the standard deviation for the blur operation in the drop shadow. Value type: <number-optional-number>; Default value: 2
; Animatable: yes
This element implements the SVGFEDropShadowElement
interface.
