      • SimpleDecalPlotter

        protected SimpleDecalPlotter​(java.lang.String name,
                             javax.swing.Icon icon,

        Constructor.
        Parameters:

    • Method Detail

      • createLayer

        public PlotLayer createLayer​(DataGeom geom,
                             DataSpec dataSpec,
                             S style)
        Description copied from interface: Plotter
        Creates a PlotLayer based on the given geometry, data and style.

        The style parameter is the result of a call to Plotter.createStyle(uk.ac.starlink.ttools.plot2.config.ConfigMap).

        The dataSpec parameter must contain the coordinates defined by this plotter's CoordGroup.

        The pointDataGeom parameter is only used if getCoordGroup(). getPositionCount returns a non-zero value, otherwise the plot does not have point positions.

        It is legal to supply null for any of the parameters; if insufficient data is supplied to generate a plot, then the method should return null.

        Creating a layer should be cheap; layers may be created and not used.

        Parameters:
        geom - indicates base position coordinates and their mapping to points in the data space; if non-null, the data geom's DataGeom.hasPosition() method will return true
        dataSpec - specifies the data required for the plot
        style - data style as obtained from createStyle
        Returns:
        new plot layer, or null if no drawing will take place

      • getLayerOpt

        protected abstract LayerOpt getLayerOpt​(S style)
        Indicates the layer optimisation options that apply to a given style.
        Parameters:
        style - plot style
        Returns:
        layer options

      • paintData2D

        protected abstract void paintData2D​(Surface surface,
                                    DataStore dataStore,
                                    DataGeom geom,
                                    DataSpec dataSpec,
                                    S style,
                                    java.awt.Graphics g,
                                    PaperType paperType)
        Called during Decal painting to perform the actual plot.
        Parameters:
        surface - plot surface
        dataStore - data storage object
        geom - data geometry
        style - plot style
        g - graphics context
        paperType - paper type
