Description: A simple transformation
Simple transformations only provide rotations about angles which a multiples of 90 degree. Together with the mirror options, this results in 8 distinct orientations (fixpoint transformations). These can be combined with a displacement which is applied after the rotation/mirror. This version acts on floating-point coordinates. A version for integer coordinates is Trans.
Here are some examples for using the DTrans class:
t = RBA::DTrans::new(0, 100) # displacement by 100 DBU in y direction # the inverse: -> "r0 0,-100" t.inverted.to_s # concatenation: -> "r90 -100,0" (RBA::DTrans::new(RBA::DTrans::R90) * t).to_s # apply to a point: -> "0,100" RBA::DTrans::new(RBA::DTrans::R90).trans(RBA::DPoint::new(100, 0))
See The Database API for more details about the database objects.

_unmanage | Signature: void _unmanage Description: Marks the object as no longer owned by the script side. Calling this method will make this object no longer owned by the script's memory management.

Technically speaking, this method will turn the script's reference into a weak reference. After the script engine decides to delete the reference, the object itself will still exist. If the object is not managed otherwise, memory leaks will occur. Usually it's not required to call this method. It has been introduced in version 0.24. | |||||||
