| 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 |
