Example 1 with ColorMap

use of org.csstudio.display.builder.model.properties.ColorMap in project org.csstudio.display.builder by kasemir.

the class ImageRepresentation method coloringChanged.

/**
 * Changes that affect the coloring of the image but not the zoom, size
 */
private void coloringChanged(final WidgetProperty<?> property, final Object old_value, final Object new_value) {
    image_plot.setInterpolation(Interpolation.values()[model_widget.propDataInterpolation().getValue().ordinal()]);
    final ColorMap colormap = model_widget.propDataColormap().getValue();
    final ColorMappingFunction map_function;
    if (colormap instanceof PredefinedColorMaps.Predefined)
        map_function = NamedColorMappings.getMapping(((PredefinedColorMaps.Predefined) colormap).getName());
    else
        map_function = value -> ColorMappingFunction.getRGB(colormap.getColor(value));
    image_plot.setColorMapping(map_function);
}

Example 2 with ColorMap

use of org.csstudio.display.builder.model.properties.ColorMap in project org.csstudio.display.builder by kasemir.

the class ColorMapDialog method updateMapFromSections.

/**
