- Description
- -----------
- Custom code to generate previews. Please check "file_dialog/thumbnail_size" in EditorSettings to find out the right size to do previews at.
- Method Descriptions
- -------------------
- .. _class_EditorResourcePreviewGenerator_method_generate:
- - :ref:`Texture<class_Texture>` **generate** **(** :ref:`Resource<class_Resource>` from, :ref:`Vector2<class_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).
- ----
- .. _class_EditorResourcePreviewGenerator_method_generate_from_path:
- - :ref:`Texture<class_Texture>` **generate_from_path** **(** :ref:`String<class_String>` path, :ref:`Vector2<class_Vector2>` size **)** virtual
- Generate a preview directly from a path with the specified size. Implementing this is optional, as default code will load and call :ref:`generate<class_EditorResourcePreviewGenerator_method_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_method_handles:
- - :ref:`bool<class_bool>` **handles** **(** :ref:`String<class_String>` type **)** virtual
- Returns if your generator supports this resource type.
