801 +The layer a node is placed in is usually computed by the layer assignment algorithms. However, sometimes certain nodes need to be placed in the first or in the last layer (for example, nodes that represent inputs from the outside). The layer constraint option can be set on such nodes to do just that.

858 +Decides which algorithm is used to compute the y coordinate of each node. This influences the length of edges, the number of edge bends, and the height of the diagram. We have different algorithms available, with different optimization goals:

861 +Minimizes the number of edge bends at the expense of diagram size: diagrams drawn with this algorithm are usually higher than diagrams drawn with other algorithms.

863 +Computes a balanced placement.
864 +* BUCHHEIM_JUENGER_LEIPERT
865 +Also computes a balanced placement, but a little faster.

875 +Since ports have a size, we need a concrete point inside the port that edges should start or end in. In KLay Layered, this is referred to as the //port anchor//. By default, the center of each port is used as its port anchor, but this behavior can be overridden by setting an explicit port anchor.
