NAME

Page − defines and displays a visual boundary for a viewer

SYNOPSIS

#include <Unidraw/page.h>

DESCRIPTION

A Page object delineates an area of interest in a viewer.  The page’s appearance guides the user to stay within a particular area, and the page’s bounding box defines the total scrollable area in the viewer.  Page displays a rectangle by default, but the boundary can be an arbitrary graphic.  The page occludes any graphical components in the viewer.  A typical use for a page is to define the page boundary in a drawing editor; graphics beyond this area will not appear on the printed page.
