AtlasTexture
============

**Inherits:** :ref:`Texture<class_texture>` **<** :ref:`Resource<class_resource>` **<** :ref:`Reference<class_reference>` **<** :ref:`Object<class_object>`

**Category:** Core

Brief Description
-----------------

Packs multiple small textures in a single, bigger one. Helps to optimize video memory costs and render calls.

Member Variables
----------------

- :ref:`Texture<class_texture>` **atlas** - The texture that contains the atlas. Can be any [Texture] subtype.
- :ref:`Rect2<class_rect2>` **margin** - The margin around the region. The [Rect2]'s 'size' parameter ('w' and 'h' in the editor) resizes the texture so it fits within the margin.
- :ref:`Rect2<class_rect2>` **region** - The AtlasTexture's used region.

Description
-----------

:ref:`Texture<class_texture>` resource aimed at managing big textures files that pack multiple smaller textures. Consists of a :ref:`Texture<class_texture>`, a margin that defines the border width,

and a region that defines the actual area of the AtlasTexture.
