<h3>方法示例</h3>
<h4>1.开启/关闭图纸测量功能</h4>
<p><strong>简要描述</strong>:
<strong>接口</strong>:
<code>beginMeasure()</code> 打开测量
<code>endMeasure()</code> 关闭测量
<strong>示例</strong>:</p>
<pre><code class="language-javascript">var mApplication2DConfig = new BCore2DFast.Application.Application2DConfig();
var mApplication2D = new BCore2DFast.Application.Application2D(mApplication2DConfig);
var mViewer2D = new BCore2DFast.Viewer.Viewer2D('bcorecontainer-2d', new BCore2DFast.Viewer.Viewer2DConfig());
mApplication2D.addViewer2D(mViewer2D);
mViewer2D.initViewer2D('accessToken');
// 建议初始化引擎后再初始化测量
var measureConfig = new BCore2DFast.Extension2D.MeasureConfig(mViewer2D);
var measure = new BCore2DFast.Extension2D.MeasureManager(measureConfig);
measure.beginMeasure(); //开启测量
...
//关闭测量
measure.endMeasure();</code></pre>
<hr />
<h4>2.获取/设置测量工具类型</h4>
<p><strong>接口</strong>:
<code>getMeasureType()</code> 获取测量工具类型
<code>setMeasureType(type)</code> 设置测量工具类型
<strong>示例</strong>:</p>
<pre><code class="language-javascript">let mApplication2DConfig = new BCore2DFast.Application.Application2DConfig();
let mApplication2D = new BCore2DFast.Application.Application2D(mApplication2DConfig);
let mViewer2D = new BCore2DFast.Viewer.Viewer2D('bcorecontainer-2d', new BCore2DFast.Viewer.Viewer2DConfig());
mApplication2D.addViewer2D(mViewer2D);
mViewer2D.initViewer2D('accessToken');
// 建议初始化引擎后 再初始化测量
let measureConfig = new BCore2DFast.Extension2D.MeasureConfig(mViewer2D);
let measure = new BCore2DFast.Extension2D.MeasureManager(measureConfig);
let measureType = measure.getMeasureType(); //获取测量工具类型
//设置设置测量工具类型
measure.setMeasureType(BCore2DFast.Static.MeasureType.ANGLE);</code></pre>
<p><strong>返回值说明</strong>:
<code>measureType</code> : <code>string</code> - 可选值： "Length", "Angle", "Area" </p>
<hr />
<h4>3.计算多边形面积</h4>
<p><strong>接口</strong>: <code>calcPolygonArea(pointsData)</code>
<strong>参数</strong>:
<code>pointsData</code> : <code>number[]</code> - 坐标值数组，例如: [1, 1, 0, 0, 2, 0]</p>
<p><strong>示例</strong>:</p>
<pre><code class="language-javascript">let mApplication2DConfig = new BCore2DFast.Application.Application2DConfig();
let mApplication2D = new BCore2DFast.Application.Application2D(mApplication2DConfig);
let mViewer2D = new BCore2DFast.Viewer.Viewer2D('bcorecontainer-2d', new BCore2DFast.Viewer.Viewer2DConfig());
mApplication2D.addViewer2D(mViewer2D);
mViewer2D.initViewer2D('accessToken')
// 建议初始化引擎后 再初始化测量
let measureConfig = new BCore2DFast.Extension2D.MeasureConfig(mViewer2D);
let measure = new BCore2DFast.Extension2D.MeasureManager(measureConfig);
let area = measure.calcPolygonArea([0, 0, 0, 10, 0, 0, 10, 10, 0, 0, 10, 0]);</code></pre>
<p><strong>返回值说明</strong>:
<code>area</code> : <code>number</code> - 计算成功返回面积，计算失败返回 -1</p>
<h4>4.获取测量工具状态</h4>
<p><strong>接口</strong>: <code>getMeasureState()</code><br />
<strong>示例</strong>:</p>
<pre><code class="language-javascript">var state = measure.getMeasureState();</code></pre>
<p><strong>返回值说明</strong>:
<code>active</code> : <code>boolean</code> - 是否开启测量
<code>type</code> : <code>BCore.Static.MeasureType</code> - 测量类型
<code>measureState</code> : <code>string</code> - "DOING" 或 "DONE"</p>
<h4>5.获取/设置测量结果标签可见性</h4>
<p><strong>接口</strong>:
<code>getMeasureTagsVisible()</code> 获取测量结果标签可见性
<code>setMeasureTagsVisible()</code> 设置测量结果标签可见性(默认可见)
示例**:</p>
<pre><code class="language-javascript">var mApplication2DConfig = new BCore2DFast.Application.Application2DConfig();
var mApplication2D = new BCore2DFast.Application.Application2D(mApplication2DConfig);
var mViewer2D = new BCore2DFast.Viewer.Viewer2D('bcorecontainer-2d', new BCore2DFast.Viewer.Viewer2DConfig());
mApplication2D.addViewer2D(mViewer2D);
mViewer2D.initViewer2D('accessToken')
// 建议初始化引擎后 再初始化测量
let measureConfig = new BCore2DFast.Extension2D.MeasureConfig(mViewer2D);
let measure = new BCore2DFast.Extension2D.MeasureManager(measureConfig);
console.log(measure.getMeasureTagsVisible()); //打印测量结果标签可见性
measure.setMeasureTagsVisible(false); //设置测量结果标签 - 不可见</code></pre>
