Examples of ColorMapper

com.visitrend.ndvis.colormapper.ColorMapper

This Class allows the user to specify SQL queries and associate them with a discrete color or color gradient. If a discrete color is specified, then each row of the ResultSet will be mapped to one pixel in the image, and that pixel will be colored that discrete color. If a gradient is selected, then each row of the result set will have its first 1 to 3 numeric columns used to determine the RGB color components of pixels to create a gradient. The gradient is normalized for all ResultSet rows based on the highest and lowest values in the ResultSet for each column participating as a color component in the gradient. @author John T.

simtools.ui.ColorMapper

This class maps data sources and index to colors. The mapping is user defined, and based for example on the value of the data source For example, green value < 10, red above. Useful for making plots with "alarm" colors The data source shall not be saved into the object. Rather, this class goal is to implement a mapping independent of the data source given.
