  12. Description
  13. -----------
  14. Native image datatype. Contains image data which can be converted to an :ref:`ImageTexture<class_ImageTexture>` and provides commonly used *image processing* methods. The maximum width and height for an **Image** are :ref:`MAX_WIDTH<class_Image_constant_MAX_WIDTH>` and :ref:`MAX_HEIGHT<class_Image_constant_MAX_HEIGHT>`.
  15. An **Image** cannot be assigned to a texture property of an object directly (such as :ref:`Sprite2D.texture<class_Sprite2D_property_texture>`), and has to be converted manually to an :ref:`ImageTexture<class_ImageTexture>` first.
  16. \ **Note:** The maximum image size is 16384×16384 pixels due to graphics hardware limitations. Larger images may fail to import.

  904. Saves the image as a WebP (Web Picture) file to a byte array. By default it will save lossless. If ``lossy`` is true, the image will be saved lossy, using the ``quality`` setting between 0.0 and 1.0 (inclusive).
