Examples of org.apache.fop.area.PageViewport

org.apache.fop.area.PageViewport
Page viewport that specifies the viewport area and holds the page contents. This is the top level object for a page and remains valid for the life of the document and the area tree. This object may be used as a key to reference a page. This is the level that creates the page. The page (reference area) is then rendered inside the page object
