RGB Balance Filter (`rgbb')

The RGB Balance filter allows you to independently adjust the alpha, red, green and blue channels of a single source. The effect adjusts every pixel in the source, multiplying the red component of the pixel by the value of the Red Multiplier parameter, the green component by the value of the Green Multiplier parameter, and so on.

The RGB Balance filter takes a maximum of one source and has three parameters.
