Transformations

    :alt: Transformations Section of Layer Group or Source Controller.

There are two main types of transformation that can be applied to the members of a :ref:`Layer Group<layergroups>`, or to sources in the :ref:`Source Manager<sourcemanager>`.
The two buttons located at the bottom of any Layer Group's controller, or any Source controller, accessed by clicking the corresponding :ref:`'Edit Pencil'<input>`, allow for translations to be applied.

* The leftmost button adds a :ref:`Pan Translation<pantrans>` - *along* an axis.
* The rightmost button adds an :ref:`Angular Rotation<angtrans>` - *about* an axis.

Transformations are placed in a list once added to a controller, allowing for multiple transformations to be applied. This is called :ref:`Transformation Stacking<stacking>`.
