Example 1 with ColorModelRange

use of org.knime.core.data.property.ColorModelRange in project knime-core by knime.

the class ColorExtractNodeModel method extractColorTable.

private DataTable extractColorTable(final DataTableSpec colorSpec) throws InvalidSettingsException {
    // first column has column handler (convention in ColorHandlerPO)
    ColorHandler clrHdl = colorSpec.getColumnSpec(0).getColorHandler();
    final ColorModel model = clrHdl.getColorModel();
    if (model.getClass() == ColorModelNominal.class) {
        ColorModelNominal nom = (ColorModelNominal) model;
        return extractColorTable(nom);
    } else if (model.getClass() == ColorModelRange.class) {
        ColorModelRange range = (ColorModelRange) model;
        return extractColorTable(range);
    } else {
        throw new InvalidSettingsException("Unknown ColorModel class: " + model.getClass());
    }
