Description

The TexturePack class specifies a texture pack (or texture atlas). A texture atlas is a large image which contains many smaller sub-images.
Gideros supports dynamic creation of texture atlases and pre-packed texture atlasses by using "Gideros Texture Packer" tool.


<h3>Dynamic Creation of Texture Packs</h3>

To create a texture pack dynamically (at run-time), create TexturePack object with a table of file names of textures.

<pre><code>local pack = TexturePack.new({"1.png", "2.png", "3.png", "4.png")}</code></pre>
<h3>Static Creation of Texture Packs</h3>

To create a pre-packed texture atlas, use "Gideros Texture Packer" tool:

![images/texture_packer.png]

This tool exports two files: A .txt` file that specifes the positions of texture regions and a `.png file of packed texture.
Use these two files to create texture pack:
<pre><code>local pack = TexturePack.new("pack.txt", "pack.png")</code></pre>

Methods

TexturePack.new - creates a new TexturePack object
TexturePack.new -
TexturePack:getTextureRegion - returns the texture region of texture pack

Events
