Class: Texture
Description
Asynchronously loads a texture from a file.
Texture.loadAsync(callback,filename,filtering,options)
Parameters
callback: (function) the function will be called with the Texture object as argument or an error as second argument.
filename: (string) the name of the texture file to be loaded.
filtering: (boolean, default = false) whether or not the texture is filtered.
options: (table, optional) a table that specifies optional parameters. The following options are supported:
- transparentColor: specifies which color stands for transparent, for formats that don't supply an alpha channel such as JPEG
- wrap: how to treat texels outside the texture. Possible values are Texture.CLAMP and Texture.REPEAT.
- format: the GPU pixel format for the texture
- extend: wether the texture should be extended to a power of two size. Defaults to true.
- scale: the scale at which this texture was made, if it cannot be determined by a suffix. Defaults to 1.
Example
Texture.loadAsync(function (texture, error)
stage:addChild(Bitmap.new(texture))
end,"image.png", true, {wrap = Texture.REPEAT})
