The default value for <dot_density> is 1.0, the parameter can be set in the range from 0.0 to 1.0 (values above 1.0 do not increase the dot density further). The default value for <dot_size> is also 1.0, which creates dots at size scales varying between 10 cm and few m. The parameter is a multiplier for these default values, i.e. at a value of 10 dots of ~10-20 m size are created. | The default value for <dot_density> is 1.0, the parameter can be set in the range from 0.0 to 1.0 (values above 1.0 do not increase the dot density further).
