5 +KIML defines a whole set of standard layout options that many layout algorithms support. Whether an algorithm supports a layout option depends on the option and on the algorithm. When an option is supported by an algorithm, it may change the option's default value. Algorithms may also provide more specialized documentation for a given layout option.

15 +Beside a human-readable name, layout options are defined by the following properties:
14 14  
15 15  * An ID to identify them.
16 -* A type. One of Boolean, String, Int, Float, Enum, EnumSet (a s{{code language="none"}}et{{/code}} over a given enumeration), or Object (a non-primitive Java object). The types Enum and EnumSet have to be further defined by an enumeration class. The Object type can be constricted to a certain Java class.
17 -* The kinds of graph objects the option applies to. At least one of Nodes, Edges, Ports, Labels, or Parents (nodes that have children, including the diagram root node). Parents-applicable options affect whole graphs or subgraphs, while options with other application targets affect only single graph elements.
18 -* An optional default value. A default value may also be provided by the layout algorithm using the option, or by the modeling application you are using. In these cases the value given here is overridden.

19 +* The kinds of graph objects the option applies to. At least one of Parents (nodes that have children, including the diagram root node), Nodes, Edges, Ports, and Labels.
20 +* An optional default value. If an option is not set on an object and if the option does not have a default value, {{code language="none"}}null{{/code}} is returned when it is accessed.

20 -Layout options can be assigned to two main categories: user options and programmatic options.
22 +KIML defines the following set of layout options:

22 -== User Options ==
23 -
24 -User options are those that you can see in the "//Layout View//" available in Eclipse if the KIML user interface is installed. That view is restricted to layout options that are supported by the currently active layout algorithm. Furthermore, some options are visible only when the //Show Advanced Properties// button is active in the view.

The value can be either the identifier of a layout algorithm or the identifier of a layout type. In the latter case the algorithm with highest priority of that type is applied. It is possible to set different values for this option on subgraphs of a hierarchical graph, where a subgraph is identified by a parent node. A layout algorithm is responsible to process only the direct content of a given parent node. An exception from this rule is made when the [[Layout Hierarchy>>doc:||anchor="layoutHierarchy"]] option is active.

The diagram type of an element is specified with the layout option {{code language="none"}}de.cau.cs.kieler.diagramType{{/code}}. Layout algorithms can declare which diagram types they support well, and give a priority value for each supported type. KIML decides at runtime which layout algorithm has the highest priority for a given diagram, so that the most suitable algorithm is always used. Usual values for such priorities are between 1 and 10, where the highest value should only be assigned if the algorithm is especially designed for diagrams of the respective type, or if it has proven to be very adequate for them. Lower values should be given if the algorithm is able to draw the diagrams correctly, but with lower quality of the resulting layout.

If the offset is not defined for a given port, a layout algorithm can try to infer the offset from the port's coordinates and its node's size in the input graph. This of course requires both properties to be set to sensible values.
