Specify the annotation maximal wrapping width.

This parameter is used only when the wrapping optimization is selected (see "Annotations | Wrapping | Optimize" parameter). In that case, some annotation may become so wide that, although the diagram will be maximally compact, such annotations may get inconvenient to read (or spread too away from what they are supposed to comment). The setting specified with this parameter limits the spreading of annotations too wide.

Note that unlike "Annotations | Wrapping | Minimal Width", setting of this parameter will not automatically lead to the increase of wrapping widths of all annotations in the diagrams. It may actually change nothing at all.
Default Value:
The default value of this parameter is copied from the parameter:

DiagramKit | Layout | Nodes | Maximal Width

That is the maximal width of a simple diagram node. In most cases, this works just fine. However, if you need to display in your diagrams lots of long annotations, you may want to try larger values.
