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.
Dynamic Creation of Texture Packs
To create a texture pack dynamically (at run-time), create a TexturePack object with a table of file names of textures.
local pack = TexturePack.new({"1.png", "2.png", "3.png", "4.png"})
Static Creation of Texture Packs
To create a pre-packed texture atlas, use "Gideros Texture Packer" tool:
This tool exports two files: a .txt file that specifies the positions of texture regions and a .png file of packed texture.
Use these two files to create a texture pack:
local pack = TexturePack.new("pack.txt", "pack.png")
MethodsTexturePack.new creates a new TexturePack object from textures |
