Relative character size:
	Specifies the relative size of characters as a percentage of the distance between P1 and P2. Use this instruction to establish relative character sizes so that if the P1/P2 distance changes, the character sizes adjust to occupy the same relative ammount of space.

width : float [-100 to 100] percent, excluding 0.
height : float [-100 to 100] percent, excluding 0.

class chiplotle.hpgl.commands.TL(tp=0.5, tn=0.5)¶

Bases: chiplotle.hpgl.abstract.hpglprimitive._HPGLPrimitive

Length of ticks drawn with the XT and YT instructions.

tp : percentage of (P2y - P1y) for XT or (P2x - P1x) for YT. Denotes portion above X-axis or to the right of the Y-axis when

difference is positive.
tn : same as tp except denotes portion below the X-axis and to the left of the Y-axis. 0.5 is default for both.

class chiplotle.hpgl.commands.VS(vel=None, pen=None)¶

Bases: chiplotle.hpgl.abstract.hpglprimitive._HPGLPrimitive

Pen Velocity:	Set’s pen velocity.

vel : float [0.0 to 127.9999] (depends on plotter), None.
pen : int [1 to 8].
