Set line style.

@param hash :style

Line style. Array with keys among the following:

  • width (float): Width of the line in user units.

  • cap (string): Type of cap to put on the line. Possible values are: butt, round, square. The difference between “square” and “butt” is that “square” projects a flat end past the end of the line.

  • join (string): Type of join. Possible values are: miter, round, bevel.

  • dash (mixed): Dash pattern. Is 0 (without dash) or string with series of length values, which are the lengths of the on and off dashes. For example: “2” represents 2 on, 2 off, 2 on, 2 off, …; “2,1” is 2 on, 1 off, 2 on, 1 off, …

  • phase (integer): Modifier on the dash pattern which is used to shift the point at which the pattern starts.

  • color (array): Draw color. Format: array(GREY) or array(R,G,B) or array(C,M,Y,K).
