Remarks

The LegendClassFormat defines the aspect of a LegendItem. Each LegendItem has its own LegendClassFormat which not surprisingly can be accessed through ILegendItem::LegendClassFormat.

A legend item may consist of a patch, a label and an optional description:

An area patch will be used for a layer displaying polygons and a line patch for a layer displaying lines.

A number of properties are provided to manage the patches used for this legend item. For more on patches, see the help under IPatch.

LabelSymbol and DescriptionSymbol allow you to set the TextSymbol used to display the Label and Description.
