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 |
