Detailed Description

Singleton that handles the loading of textures.

Once the texture is loaded, the next time it will return. A reference of the previously loaded texture reducing GPU & CPU memory.

Texture2D* addImage ( const std::string &  filepath)

Returns a Texture2D object given an filename.

If the filename was not previously loaded, it will create a new Texture2D. Object and it will return it. It will use the filename as a key. Otherwise it will return a reference of a previously loaded image. Supported image extensions: .png, .bmp, .tiff, .jpeg, .pvr.

Parameters
filepathA null terminated string.
var addImage ( var  filepath)

Returns a Texture2D object given an filename.

If the filename was not previously loaded, it will create a new Texture2D. Object and it will return it. It will use the filename as a key. Otherwise it will return a reference of a previously loaded image. Supported image extensions: .png, .bmp, .tiff, .jpeg, .pvr.

Parameters
filepathA null terminated string.
local addImage ( local  filepath)

)
virtual

Returns a Texture2D object given a file image.

If the file image was not previously loaded, it will create a new Texture2D object and it will return it. Otherwise it will load a texture in a new thread, and when the image is loaded, the callback will be called with the Texture2D as a parameter. The callback will be called from the main thread, so it is safe to create any cocos2d object from the callback. Supported image extensions: .png, .jpg

callbackA callback function would be invoked after the image is loaded.
