<class name="TextureLayered" inherits="Texture" version="4.1" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../class.xsd">
	<brief_description>
		Base class for texture types which contain the data of multiple [Image]s. Each image is of the same size and format.
	</brief_description>
	<description>
		Base class for [ImageTextureLayered] and [CompressedTextureLayered]. Cannot be used directly, but contains all the functions necessary for accessing the derived resource types. See also [Texture3D].
		Data is set on a per-layer basis. For [Texture2DArray]s, the layer specifies the array layer.
		All images need to have the same width, height and number of mipmap levels.
		A [TextureLayered] can be loaded with [method ResourceLoader.load].
		Internally, Godot maps these files to their respective counterparts in the target rendering driver (Vulkan, OpenGL3).

		</method>
		<method name="get_format" qualifiers="const">
			<return type="int" enum="Image.Format" />
			<description>
				Returns the current format being used by this texture. See [enum Image.Format] for details.
			</description>
		</method>
		<method name="get_height" qualifiers="const">
			<return type="int" />
			<description>
				Returns the height of the texture in pixels. Height is typically represented by the Y axis.

			<return type="Image" />
			<param index="0" name="layer" type="int" />
			<description>
				Returns an [Image] resource with the data from specified [param layer].

		</method>
		<method name="get_layered_type" qualifiers="const">
			<return type="int" enum="TextureLayered.LayeredType" />
			<description>
				Returns the [TextureLayered]'s type. The type determines how the data is accessed, with cubemaps having special types.

				Returns the width of the texture in pixels. Width is typically represented by the X axis.
			</description>
		</method>
		<method name="has_mipmaps" qualifiers="const">
			<return type="bool" />
			<description>
				Returns [code]true[/code] if the layers have generated mipmaps.
