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

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

local addImage ( local 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

Texture2D* addImage	(	Image *	image,
		const std::string &	key
	)

Returns a Texture2D object given an Image.

If the image was not previously loaded, it will create a new Texture2D object and it will return it. Otherwise it will return a reference of a previously loaded image. The "key" parameter will be used as the "key" for the cache. If "key" is nil, then a new texture will be created each time.

var addImage	(	var	image,
		var	key
	)

Returns a Texture2D object given an Image.

If the image was not previously loaded, it will create a new Texture2D object and it will return it. Otherwise it will return a reference of a previously loaded image. The "key" parameter will be used as the "key" for the cache. If "key" is nil, then a new texture will be created each time.

local addImage	(	local	image,
		local	key
	)

Returns a Texture2D object given an Image.

If the image was not previously loaded, it will create a new Texture2D object and it will return it. Otherwise it will return a reference of a previously loaded image. The "key" parameter will be used as the "key" for the cache. If "key" is nil, then a new texture will be created each time.

bool reloadTexture ( const std::string & fileName )

Reload texture from the image file If the file image hasn't loaded before, load it.

Otherwise the texture will be reloaded from the file image. The "filenName" parameter is the related/absolute path of the file image. Return true if the reloading is succeed, otherwise return false.
