This module permits to define dash patterns, that are used to draw lines in different styles
type tThe abstract type of dash patterns
val evenly : t The pattern composed of evenly spaced dashes
val withdots : t The pattern composed of evenly spaced dashes
The pattern composed of evenly spaced dots
val scaled : Num.t -> t -> t Scale a dash pattern
val shifted : Point.t -> t -> t Scale a dash pattern
Shift a dash pattern
type on_offval on : Num.t -> on_off val off : Num.t -> on_off val pattern : on_off list-> t This function, together with the type on_off permits to construct custom dash patterns, by giving a list of on / off constructors, with corresponding lengths
