DataHolderLib::ColorLookupTable Class Reference

Detailed Description

A colour look-up table stored as a vector containing for each entry id - value for which the colour is stored colour - RGBA value name - a name referencing the colour (such as a stratigraphic layer) Colours from the table can then be accessed using either id or name.
