Default formatting information for the legend classes. Renderer may override.

Description

The layer can provide legend class formatting information via ILegendClass.Format. This makes it possible to store legend formatting information with layers in metadata-like fashion. However, layers normally do not provide a LegendClassFormat object. Rather, legend formatting information usually comes from the legend. ILegendItem.LegendClassFormat is used and some patch settings can come from ILegend.LegendFormat .

So, when a legend is created, the code follows this logic:

  1. Check if ILegendClass.Format exists for the layer. If not, use ILegendItem.LegendClassFormat.
  2. For the patch settings, if a setting in ILegendItem.LegendClassFormat is null, then use the default value in ILegend.LegendFormat.
