Example 1 with RTImagePlotListener

use of org.csstudio.javafx.rtplot.RTImagePlotListener in project org.csstudio.display.builder by kasemir.

the class ImagePlot method updateRoiFromScreen.

/**
 * @param roi RegionOfInterest to move to new location
 *  @param screen_pos Screen position, will be converted into axes' values
 */
private void updateRoiFromScreen(final int index, final Rectangle2D screen_pos) {
    final RegionOfInterest roi = rois.get(index);
    // Convert screen position to axis values
    final double x0 = x_axis.getValue((int) screen_pos.getMinX()), y0 = y_axis.getValue((int) screen_pos.getMinY()), x1 = x_axis.getValue((int) screen_pos.getMaxX()), y1 = y_axis.getValue((int) screen_pos.getMaxY());
    final double x = Math.min(x0, x1);
    final double y = Math.min(y0, y1);
    final Rectangle2D region = new Rectangle2D(x, y, Math.abs(x1 - x0), Math.abs(y1 - y0));
    roi.setRegion(region);
    requestUpdate();
    // Notify listener of ROI change
    final RTImagePlotListener listener = plot_listener;
    if (listener != null)
        listener.changedROI(index, roi.getName(), roi.getRegion());
}

Example 2 with RTImagePlotListener

use of org.csstudio.javafx.rtplot.RTImagePlotListener in project org.csstudio.display.builder by kasemir.

    final RTImagePlotListener listener = plot_listener;
    if (listener == null)
        return;
    final AxisRange<Double> range = axis.getValueRange();
    if (axis == x_axis)
        listener.changedXAxis(range.getLow(), range.getHigh());
    else
