SR - Set Relative Character Size

SR [

width

height

] [;]

width ; the width of printed characters expressed as a percentage of the x-component of the distance between

P1 and P2.

height ; the height of printed characters expressed as a percentage of the y-component of the distance

between P1 and P2.

• This command allows you to specify the size of the character that you print with the LB instruction, relative

to the scaling points P1 and P2.

• width sets the character width to a percentage of |P2x-P1x| and is a clamped real number. Negative values

of width produce right-to-left mirror image characters

• height sets the character height to a percentage of |P2y-P2y| and is a clamped real number. Negative values

of height produce upside-down mirror image character.

• If you change the positions of P1 and P2, the character size will change unless the scaling points remain in

the same relative positions.

• If you move P2 to the left of, or below P1, characters will appear in mirror image.

• If you change the character size, the line width used to draw stick font characters may also change.

• If you omit the parameters, the character size is as specified by the most recent SD or AD command.
