         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''. The markup equivalent of this function is <a href="#grayscaleEquivalent">given below</a>.

A value of ''0deg'' leaves the input unchanged. Implementations must not normalize this value in order to allow animations beyond ''360deg''.

         Note: The opacity filter function is not meant to be a shorthand of the 'opacity' property. Furthermore, it allows setting the transparency of intermediate filter primitive results before passing to the next filter primitive. If the opacity filter function is set as last filter primitive, the value of the 'opacity' property is multiplied on top of the value of the filter function, which may result in a more transparent content.

 This filter primitive creates an image using the Perlin turbulence function. It allows the synthesis of artificial textures like clouds or marble. For a detailed description the of the Perlin turbulence function, see "Texturing and Modeling", Ebert et al, AP Professional, 1994. The resulting image will fill the entire <a>filter primitive subregion</a> for this filter primitive.
 
 It is possible to create bandwidth-limited noise by synthesizing only one octave.
