Méthode	Description
CreateMultiResolutionImage ( IEnumerable images ) : Image
CreateMultiSizeIcon ( IEnumerable images ) : Image
Dispose ( ) : void
FromCustomLoader ( IImageLoader loader, string fileName ) : Image

FromResource ( Assembly assembly, string resource ) : Image	Loads an image from a resource This method will look for alternative versions of the image with different resolutions. For example, if a resource is named "foo.png", this method will load other resources with the name "[email protected]", where XXX can be any arbitrary string. For example "[email protected]". Each of those resources will be considered different versions of the same image.
