The following sample demonstrates how the ItemPathHorizontalAlignment can be used to align the path horizontally within the XamCarouselPanel. In this example, the ItemPathStretch is set to Uniform so that the aspect ratio of the Path is maintained. When the path width is less than the available area, the path will be aligned to the Left edge of the panel.
