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.

SL - Character slant   

SL [ tan 



 ] [;] 

tan 



 - tangent of character slant angle (



) 



This command determines the slant of characters printed with subsequent LB commands. 





 is the angle between characters and the vertical.    A positive value of 



 ( and tan 



 ) produces forward 

sloping characters,    while a negative value results in characters which slant backwards. 



Values of tan 



 are clamped real numbers. 



A value of 0 for tan 



 results in upright characters. 



If you omit the parameter,    tan 



 is take to be 0 and any characters printed will be upright.
