An element describes one or more image objects, such as separators, static text, and pictures. An element contains information about the type of the object, its geometrical features, its likely location, and relationships with other objects. The program uses the properties of an element to look for the object it describes and determines a region for the object. A region is made up of one or more rectangles enclosing the object. Next, the program uses the detected objects to locate blocks.

Simple and compound elements

Elements fall into two categories: A Table element is neither simple nor compound and cannot be converted into an element of any other type. You can convert elements of one type into elements of another type, but you cannot convert compound elements into simple elements or vice versa. To convert an element, select the Convert To command on its shortcut menu.

How elements are displayed in the tree

An element may be displayed differently depending on its properties: Elements are joined together to form layout alternatives. In the project tree, each layout alternative is marked with Layout alternative icon.
