Interface UnitConverter

All Known Implementing Classes:

AbstractUnitConverter, DefaultUnitConverter

public interface UnitConverter

An interface that describes how to convert general sizes to pixel sizes. For example, dialog units require a conversion that honors the font and resolution. The Sizes class delegates all size conversions to an implementation of this interface.
