Accepts two arguments (min and max) for RGB or grayscale, or six (min/max for each channel) to control each RGB channel. Arguments can be separated by commas or spaces.
Random dithering adds random noise to the image. The min and max numbers limit the range of the random noise. A good default is -0.5,0.5, which means that a middle gray pixel is 50% likely to become black and 50% likely to become white, assuming a black and white palette. So -0.2,2.0 will reduce the noise (20%), while -0.7,0.7 will increase it (70%). Values like -0.5,0.7 will bias the noise to one end of the channel(s).

: Set the seed for randomization. This will also only use one thread, to keep output deterministic. By default a different seed is chosen each time and multiple threads are used.
