Class: TexturePack
Description
Creates a new TexturePack object. This function creates the texture pack at runtime.
TexturePack.new(textures,padding,filtering,options)
Parameters
textures: (table) file names of textures
padding: (number) the spacing between textures in pixels optional
filtering: (boolean, default = false) whether or not the texture is filtered, that is smoothing the image optional
options: (table) a table that specifies optional parameters optional. Currently, "transparentColor" and "format" fields are supported
Example
Store all images in a folder to a table for use in TexturePack
local lfs = require "lfs"
local list = {}
function attrdir(path)
for file in lfs.dir(path) do
if file ~= "." and file ~= ".." then
local f = path..'/'..file
local attr = lfs.attributes(f)
if attr.mode == "file" then table.insert(list, f) end
end
end
end
attrdir("gfx/hero") -- folder to fetch images from
--local tp = TexturePack.new({"gfx/hero/HQ_Trooper_all.png", "gfx/hero/caverman.png", "gfx/hero/test01.png"})
local tp = TexturePack.new(list)
local bmp = Bitmap.new(tp:getTextureRegion("gfx/hero/caverman.png"))
stage:addChild(bmp)

Parameters
txtfile: (string) Gideros Texture Packer text file path
imagefile: (string) Gideros Texture Packer image file path
filtering: (boolean, default = false) whether or not the texture is filtered, that is smoothing the image optional
options: (table) a table that specifies optional parameters optional. Currently, "transparentColor" and "format" fields are supported
