SR, Relative Character Size

This command specifies the size of characters as a percentage of the distance between P1 and P2. Use SR to establish relative character size so that if the P1/P2 distance changes, the character size adjusts to occupy the same relative amount of space.

Parameter	Format	Range	Default
width	clamped real	–32768 to	0.75% of P2X–P1X

height	clamped real	–32768 to	1.5% of P2Y–P1Y
		32767

While the SR command is in effect (with or without parameters), changes in P1 and P2 affect the size of characters in the currently selected font.

z No Parameters— Defaults the relative character width to 0.75%

	of the distance (P2X – P1X) and the height to 1.5% of the
	distance (P2Y – P1Y).
	z Width— Sets the character width to the specified percentage of
	the distance between the X-coordinates of P1 and P2. A negative
	width parameter mirrors labels in the right-to-left direction.
Note	Changing character size also changes the apparent stroke weight of
	labels; the printer adjusts characters relative to changes in P1/P2. As
	long as the aspect ratio remains the same with changes in P1/P2,
	characters will have the same appearance relative to the new P1/P2
	rectangle.
	z Height— Sets the character height to the specified percentage of
	the distance between the Y-coordinates of P1 and P2. A negative
	height parameter mirrors labels in the top-to-bottom direction.
