47//! This class provides methods to create presentation of nodes with assigned color.
48//! There are two ways of presentation building
49//! 1. Without using texture.
50//! In this case colors of nodes are specified with DataMapOfIntegerColor and presentation
51//! is built with gradient fill between these nodes (default behaviour)
52//! 2. Using texture.
53//! In this case presentation is built with spectrum filling between nodes. For example, if
54//! one node has blue color and second one has violet color, parameters of this class may be
55//! set to fill presentation between nodes with solar spectrum.
56//! Methods:
57//! UseTexture - activates/deactivates this way
58//! SetColorMap - sets colors used for generation of texture
59//! SetColorindices - specifies correspondence between node IDs and indices of colors from color map
