class Mixpict(Mixture):
    """Radiance Mixpict Material.

    Mixpict combines two modifiers based on a picture:

    .. code-block:: shell

        mod mixpict id
        7+
                foreground background func pictfile
                funcfile u v transform
        0
        m A1 A2 .. Am

    The mixing coefficient function "func" takes three arguments, the red, green and
    blue values corresponding to the pixel at (u,v).

    Args:
        identifier: Text string for a unique Mixture ID. Must not contain spaces
            or special characters. This will be used to identify the object across
            a model and in the exported Radiance files.
        modifier: Modifier. It can be primitive, mixture, texture or pattern.
            (Default: None).
        values: An array 3 arrays for primitive data. Each of the 3 sub-arrays
            refer to a line number in the radiance primitive definitions and the
            values in each array correspond to values occurring within each line.
        is_opaque: A boolean to indicate whether this primitive is opaque.
        dependencies: A list of primitives that this primitive depends on. This
            argument is only useful for defining advanced primitives that are
            defined based on other primitives. (Default: []).

    Properties:
        * identifier
        * display_name
        * values
        * modifier
        * dependencies
        * is_modifier
