681 = The Most Important Options =
682
683 **TODO:** Write a bit of documentation about the most important layout options and how to use them, possibly with a simple example or something.
684
685 = Detailed Documentation =
686
687 This section explains every layout option in more detail. See [[the KIML documentation>>doc:KIML Layout Options]] for more information on KIML layout options. Those options are only mentioned here if KLay Layered adds some custom behavior.

692
693 {{id name="crossingMinimization"/}}
694
695 Crossing minimization determines the ordering of nodes in each layer, which influences the number of edge crossings. This option switches between one of several algorithms that can be used to minimize crossings. Possible values are:
696
697 * LAYER_SWEEP
698 The layer sweep algorithm iterates multiple times over the layers, trying to find node orderings that minimize the number of crossings. The algorithm uses randomization to increase the odds of finding a good result. To improve its results, consider increasing the //Thoroughness// option, which influences the number of iterations done. The //Randomization// seed also influences results.
699 * INTERACTIVE
700 Orders the nodes of each layer by comparing their positions before the layout algorithm was started. The idea is that the relative order of nodes as it was before layout was applied is not changed. This of course requires valid positions for all nodes to have been set on the input graph before calling the layout algorithm. The interactive layer sweep algorithm uses the //Interactive Reference Point// option to determine which reference point of nodes are used to compare positions.

708 KLay Layered tries to position nodes in a way that all edges point rightwards. This is not possible if the input graph has cycles. Such cycles have to be broken by reversing as few edges as possible. The reversed edges end up pointing leftwards in the resulting diagram. There are different cycle breaking algorithms available:
709
710 * GREEDY
711 This algorithm reverses edges greedily. The algorithm tries to avoid edges that have the //Priority// property set.
712 * INTERACTIVE
713 The interactive algorithm tries to reverse edges that already pointed leftwards in the input graph. This requires node and port coordinates to have been set to sensible values.

721 The edge spacing factor determines the amount of space between edges, relative to the regular //Spacing// value. The idea is that we don't need as much space between edges as we do between nodes.

752
753 Interactive layering, crossing minimization, and cycle breaking algorithms use node positions to sort nodes into layers or to determine the order of nodes in each layer. However, it is unclear if for example the top left corners of nodes should be compared, or the bottom left corners — different settings might lead to different results. The interactive reference point determines which part of nodes is used to compare their positions. It provides the following settings:
754
755 * TOP_LEFT
756 The top left corner of a node is taken as the reference point.
757 * CENTER
758 The center of a node is taken as the reference point.

786 In the KGraph model, edges can either connect to nodes through ports or directly. In the latter case, KLay Layered will introduce a virtual port for each edge, which results in all edges connecting to the node at different points in the final drawing. If this option is switched on, KLay Layered will only generate up to one input and one output port for each node. The option is set on a parent node and applies to all of its children, but not to the parent node itself.

838 There are heuristics in use all over KLay Layered whose results often improve with the number of iterations computed. The thoroughness is a measure for telling KLay Layered to compute more iterations to improve the quality of results, at the expense of performance.
