A tool to measure the distance between two points. Users can reset the current measurement by clicking the mouse right button. Users can press "Esc/Enter" to stop the current measurement.
declare class MeasureLine extends Measure
|(constructor)(viewer)||Create the tool.|
|getPerimeter()||Get the current measured distance.|
|setEnabled(enabled)||Enable the tool.|
Notice that we can not enable multiple measure tools at the same time. Before a new tool being enabled, the old tool must be disabled first.
Moreover, the measurement tools require mouse input and mouse input should be added to the viewer before the tool.
var ruler = new Modelo.View.Tool.MeasureLine(viewer); viewer.addTool(ruler);
