Applies a Gaussian blur to the input image. The passed parameter (the radius) defines the value of the standard deviation to the Gaussian function. The parameter is specified a CSS length, but does not accept percentage values.

]]> Applies a linear multiplier to input image, making it appear more or less bright. A value of 0% will create an image that is completely black. A value of 100% leaves the input unchanged. Other values are linear multipliers on the effect. Values of amount over 100% are allowed, providing brighter results.

]]> Adjusts the contrast of the input. A value of 0% will create an image that is completely gray. A value of 100% leaves the input unchanged. Values of amount over 100% are allowed, providing results with more contrast.

]]> Applies a drop shadow effect to the input image. A drop shadow is effectively a blurred, offset version of the input image’s alpha mask drawn in a particular color, composited below the image. Values are interpreted as for .

]]> Converts the input image to grayscale. The passed parameter defines the proportion of the conversion. A value of 100% is completely grayscale. A value of 0% leaves the input unchanged. Values between 0% and 100% are linear multipliers on the effect. Values of amount over 100% are allowed but UAs must clamp the values to 1.

]]> Applies a hue rotation on the input image. The passed parameter defines the number of degrees around the color circle the input samples will be adjusted. A value of 0deg leaves the input unchanged. Implementations must not normalize this value in order to allow animations beyond 360deg.

]]> Inverts the samples in the input image. The passed parameter defines the proportion of the conversion. A value of 100% is completely inverted. A value of 0% leaves the input unchanged. Values between 0% and 100% are linear multipliers on the effect. Values of amount over 100% are allowed but UAs must clamp the values to 1.

]]> Applies transparency to the samples in the input image. The passed parameter defines the proportion of the conversion. A value of 0% is completely transparent. A value of 100% leaves the input unchanged. Values between 0% and 100% are linear multipliers on the effect. This is equivalent to multiplying the input image samples by amount. Values of amount over 100% are allowed but UAs must clamp the values to 1.

]]> Converts the input image to sepia. The passed parameter defines the proportion of the conversion. A value of 100% is completely sepia. A value of 0% leaves the input unchanged. Values between 0% and 100% are linear multipliers on the effect. Values of amount over 100% are allowed but UAs must clamp the values to 1.

]]> Saturates the input image. The passed parameter defines the proportion of the conversion. A value of 0% is completely un-saturated. A value of 100% leaves the input unchanged. Other values are linear multipliers on the effect. Values of amount over 100% are allowed, providing super-saturated results.

]]> If the value of the filter property is none then there is no filter effect applied. Otherwise, the list of functions are applied in the order provided.

]]> The flood-color property indicates what color to used to flood the current filter primitive subregion.

]]> The flood-opacity property defines the opacity value to use across the entire filter primitive subregion. If the value includes an alpha channel, the alpha channel gets multiplied with the computed value of the flood-opacity property.

]]> The lighting-color property defines the color of the light source for filter primitives feDiffuseLighting and feSpecularLighting.
