- EditorResourcePreviewGenerator
- ==============================
- **Inherits:** :ref:`Reference<class_Reference>` **<** :ref:`Object<class_Object>`
- Custom generator of previews.
- Description
- -----------
- Custom code to generate previews. Please check ``file_dialog/thumbnail_size`` in :ref:`EditorSettings<class_EditorSettings>` to find out the right size to do previews at.

- Method Descriptions
- -------------------
- .. _class_EditorResourcePreviewGenerator_method_can_generate_small_preview:
- - :ref:`bool<class_bool>` **can_generate_small_preview** **(** **)** |virtual|
- If this function returns ``true``, the generator will call :ref:`generate<class_EditorResourcePreviewGenerator_method_generate>` or :ref:`generate_from_path<class_EditorResourcePreviewGenerator_method_generate_from_path>` for small previews as well.
- By default, it returns ``false``.
- ----
- .. _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_generate_small_preview_automatically:
- - :ref:`bool<class_bool>` **generate_small_preview_automatically** **(** **)** |virtual|
- If this function returns ``true``, the generator will automatically generate the small previews from the normal preview texture generated by the methods :ref:`generate<class_EditorResourcePreviewGenerator_method_generate>` or :ref:`generate_from_path<class_EditorResourcePreviewGenerator_method_generate_from_path>`.
- By default, it returns ``false``.
- ----
- .. _class_EditorResourcePreviewGenerator_method_handles:
- - :ref:`bool<class_bool>` **handles** **(** :ref:`String<class_String>` type **)** |virtual|
- Returns ``true`` if your generator supports the resource of type ``type``.
- .. |virtual| replace:: :abbr:`virtual (This method should typically be overridden by the user to have any effect.)`
- .. |const| replace:: :abbr:`const (This method has no side effects. It doesn't modify any of the instance's member variables.)`
- .. |vararg| replace:: :abbr:`vararg (This method accepts any number of arguments after the ones described here.)`
