Description
The SVG_Filter_Blend command sets a blend filter for the filterRef filter and returns its reference. If filterRef is not a filter reference, an error is generated.
This filter is made up of two sources, backgroundPict and picture, with the help of the mixing modes currently used by the imaging software.
The optional mode parameter can be used to set the combination mode of the pixels used for the blend (see the specification). Its value must be: "normal" (default value), "multiply", "screen", "darken" or "lighten".
The optional name parameter is the name, if any, assigned to the result of this filter primitive.
