Description: A complex transformation
A complex transformation provides magnification, mirroring at the x-axis, rotation by an arbitrary angle and a displacement. This is also the order, the operations are applied.
A complex transformation provides a superset of the simple transformation. In many applications, a complex transformation computes floating-point coordinates to minimize rounding effects. This version can transform floating-point coordinate objects.
Complex transformations are extensions of the simple transformation classes (DTrans in that case) and behave similar.
Transformations can be used to transform points or other objects. Transformations can be combined with the '*' operator to form the transformation which is equivalent to applying the second and then the first. Here is some code:
# Create a transformation that applies a magnification of 1.5, a rotation by 90 degree # and displacement of 10 in x and 20 units in y direction: t = RBA::CplxTrans::new(1.5, 90, false, 10.0, 20.0) t.to_s # r90 *1.5 10,20 # compute the inverse: t.inverted.to_s # r270 *0.666666667 -13,7 # Combine with another displacement (applied after that): (RBA::CplxTrans::new(5, 5) * t).to_s # r90 *1.5 15,25 # Transform a point: t.trans(RBA::Point::new(100, 200)).to_s # -290,170

This method is provided as last resort to remove the constness from an object. Usually there is a good reason for a const object reference, so using this method may have undesired side effects. This method has been introduced in version 0.29.6. | |||||||||
_create | Signature: void _create Description: Ensures the C++ object is created Use this method to ensure the C++ object is created, for example to ensure that resources are allocated. Usually C++ objects are created on demand and not necessarily when the script object is created. | |||||||||
_destroy | Signature: void _destroy Description: Explicitly destroys the object Explicitly destroys the object on C++ side if it was owned by the script interpreter. Subsequent access to this object will throw an exception. If the object is not owned by the script, this method will do nothing. | |||||||||
_destroyed? | Signature: [const] bool _destroyed? Description: Returns a value indicating whether the object was already destroyed This method returns true, if the object was destroyed, either explicitly or by the C++ side. The latter may happen, if the object is owned by a C++ object which got destroyed itself. | |||||||||

_manage | Signature: void _manage Description: Marks the object as managed by the script side. After calling this method on an object, the script side will be responsible for the management of the object. This method may be called if an object is returned from a C++ function and the object is known not to be owned by any C++ instance. If necessary, the script side may delete the object if the script's reference is no longer required. Usually it's not required to call this method. It has been introduced in version 0.24. | |||||||||
_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. Instead, the object must be managed in some other way. Usually this method may be called if it is known that some C++ object holds and manages this object. 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. | |||||||||

Note that the simple transformation returns the angle in units of 90 degree. Hence for a simple trans (i.e. Trans), a rotation angle of 180 degree delivers a value of 2 for the angle attribute.

is_complex? | Signature: [const] bool is_complex?
