Viewbox is inherited from ISContentControl, which means that it can contain a single object of any type (such as a string, an image, or a panel). For more information about this content model, see Content Model Overview.
Viewbox scales the content to fill the available size. It does not resize the content, but it transforms it. This means that also all text sizes and line widths were scaled. Its about the same behavior as if you set the Stretch property on an Image or Path to Uniform.
