• bool can_generate_small_preview ( ) virtual true, the generator will call generate or generate_from_path for small previews as well. false.

• Texture generate ( Resource from, Vector2 size ) virtual Generate a preview from a given resource with the specified size. This must always be 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).

• Texture generate_from_path ( String path, Vector2 size ) virtual 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).

• bool generate_small_preview_automatically ( ) virtual true, the generator will automatically generate the small previews from the normal preview texture generated by the methods generate or generate_from_path. false.

• bool handles ( String type ) virtual true if your generator supports the resource of type type.
