SetAngle (procedure)

This command rotates all subsequent commands by the angle specified. Most commands and objects that are dis-

played/printed on the document are affected by the setangle command.

Syntax

setangle( angle )

Argument

angle

Measure value specifying the angle of rotation in degrees for all subsequent commands. Use a positive value for counter-clock-

wise motion and a negative value for clockwise motion. This value is relative to the current angle, not absolute.

Code Sample Example

This example illustrates setangle().

setangle() sets a rotation for all subsequent commands. Consequently, setangle commands are cumulative. Therefore, to

restore the previous angle of rotation, you must issue a setangle command that negates whatever rotation applied.

Example

setangle(45.00) %Rotate subsequent commands by 45 degrees

show('Some text') %Display at a 45 degree angle

setangle(45.00) %Rotate subsequent commands by 45 degrees

show('Some text') %Display at a 90 degree angle

setangle(-90) %Cancel all rotations

SetDash(procedure)

Set the properties of a dashed line. Any drawing done after setdash() draws dashed instead of solid lines. You can revert to

solid lines by calling setdash() with an empty array as a parameter.

Syntax

setdash( [dashlength, spacelength] )

Argument

dash

Measure value specifying the length, in inches, of each of the dashes in the dashed line.
