public class ComputeICMMetricsStep
- extends IterateVisualProcessStep
This step performs the first layouting step. The ICM-step computes the
preferred size of all elements (that is the minimum size the element would
consume if there were infinite space available) and the minimum chunk size
(that is the biggest unbreakable content in an element).
The preferred size is based on the box size (that means: No margins
included!).
That step produces the preferred size for the nodes.
As long as paragraphs can be nested, we cannot assume anything here. A nested
paragraph can have linebreaks all the time and thus it is dangerous to skip
the ICM-Computation on such nodes. Maybe we can tweak something with a change
counter or so.
