ImageTextureLayered
继承： TextureLayered < Texture < Resource < RefCounted < Object
派生： Cubemap, CubemapArray, Texture2DArray
Base class for texture types which contain the data of multiple ImageTexture s. Each image is of the same size and format.
描述
Base class for Texture2DArray, Cubemap and CubemapArray. Cannot be used directly, but contains all the functions necessary for accessing the derived resource types. See also Texture3D.

方法说明
Error create_from_images ( images: Array Image )
Creates an ImageTextureLayered from an array of Image s. See Image.create for the expected data format. The first image decides the width, height, image format and mipmapping setting. The other images must have the same width, height, image format and mipmapping setting.
Each Image represents one layer.
void update_layer ( image: Image, layer: int )
Replaces the existing Image data at the given layer with this new image.
The given Image must have the same width, height, image format, and mipmapping flag as the rest of the referenced images.
If the image format is unsupported, it will be decompressed and converted to a similar and supported Format.
The update is immediate: it's synchronized with drawing.
