Example 1 with CoreOptions

use of org.eclipse.elk.core.options.CoreOptions in project elk by eclipse.

the class ElkUtil method applyConfiguredNodeScaling.

/**
 * Applies the scaling factor configured in terms of {@link CoreOptions#SCALE_FACTOR} to {@code node}'s
 * size data, and updates the layout data of {@code node}'s ports and labels accordingly.<br>
 * <b>Note:</b> The scaled layout data won't be reverted during the layout process, see
 * {@link CoreOptions#SCALE_FACTOR}.

 * @param node
 *            the node to be scaled
