Description


The TextureRegion class specifies a texture and a rectangular region in it. It is used to define independent texture regions
within a texture atlas which is a large image, which contains many smaller sub-images.

Examples

Example

local texture = Texture.new("atlas.png")

-- define 4 equal regions of size 100x100 from "atlas.png"
local region1 = TextureRegion.new(texture, 0,   0,   100, 100)
local region2 = TextureRegion.new(texture, 100, 0,   100, 100)
local region3 = TextureRegion.new(texture, 100, 100, 100, 100)
local region4 = TextureRegion.new(texture, 0,   100, 100, 100)

-- add these regions to scene tree
local bitmap1 = Bitmap.new(region1)
local bitmap2 = Bitmap.new(region2)
local bitmap3 = Bitmap.new(region3)
local bitmap4 = Bitmap.new(region4)

stage:addChild(bitmap1)
stage:addChild(bitmap2)
stage:addChild(bitmap3)
stage:addChild(bitmap4)

Methods

TextureRegion.new creates a new TextureRegion object
TextureRegion.new
TextureRegion:getRegion returns the coordinates of the region
TextureRegion:getScale returns the scale ratio of the underlying atlas
TextureRegion:setRegion sets the coordinates of the region
