Member Function Description
---------------------------

.. _class_EditorResourcePreviewGenerator_generate:

- :ref:`Texture<class_texture>`  **generate**  **(** :ref:`Resource<class_resource>` from  **)** virtual

Generate a preview from a given resource. This must be always implemented.

Returning an empty texture is an OK way to fail and let another generator take care.

Care must be taken because this function is always called from a thread (not the main thread).

.. _class_EditorResourcePreviewGenerator_generate_from_path:

- :ref:`Texture<class_texture>`  **generate_from_path**  **(** :ref:`String<class_string>` path  **)** virtual

Generate a preview directly from a path, implementing this is optional, as default code will load and call generate()

Returning an empty texture is an OK way to fail and let another generator take care.

Care must be taken because this function is always called from a thread (not the main thread).

.. _class_EditorResourcePreviewGenerator_handles:

- :ref:`bool<class_bool>`  **handles**  **(** :ref:`String<class_string>` type  **)** virtual

Return if your generator supports this resource type.
