Table 6-13 Absolute Direction Command Parameters
Parameter
run (or cos Ø)
rise (or sin Ø)
The DI command updates the carriage return point to the current location. While the DI
command is in effect, with or without parameters, the text printing direction is not affected
by changes in the locations of P1 and P2.
No parameters - Defaults the text printing direction to absolute and horizontal (parallel to
X-axis). Equivalent to (DI1,0).
Run or Cos Ø - Specifies the X-component of the text printing direction.
Rise or Sin Ø - Specifies the Y-component of the text printing direction.
Together, the parameters specify the slope and direction of the printed characters.
You can express the parameters in measured units as rise and run, or using the
trigonometric functions cosine and sine according to the following relationship:
Where: run and rise = number of measured units
Ø = the angle measured in degrees
sin Ø/cos Ø = rise/run
–1
Ø = tan (rise/run)
and
tan Ø = sin Ø/cos Ø
NOTE: Bit map characters are always printed
orthogonally to the page. Scalable characters
print in the direction specified. Using the DI
(and DR) command, you can therefore place text
anywhere on the page in any orientation.
