<p>    上述两种方式都可以实现改变底图颜色的需求，但实现的逻辑有所区别。<code>className</code>是在<code>canvas</code>节点添加了滤镜，作用到载入画布的所有图像，不作用于原始瓦片。<code>tileLoadFunction</code>则是将请求的原始瓦片用滤镜预处理一遍产生一张加了滤镜的新瓦片，然后再加到<code>canvas</code>中的。将两种实现方式的地图导出就能看到差异了。</p>

<p>官方给出了<a href="https://github.com/winsw/winsw/blob/master/doc/installation.md" target="_blank" rel="noopener">安装指南</a>：</p>
<p><img src="https://i.loli.net/2021/01/23/zIY2KXuygHGdUvM.png" alt="image-20201218172925043.png"></p>
</li>
</ol>
<p> 步骤如下：</p>
<ul>
<li><p>将下载下来的exe 和 xml 放在<code>jar</code>同级目录下</p>
<p><img src="https://i.loli.net/2021/01/23/KJCE1h6XrWyHoGv.png" alt="image-20201218174950800.png"></p>
</li>
<li><p>更改exe 和 xml 的文件名改为和<code>jar</code> 同名。（假如我的项目名为<code>install-service.jar</code> 则将 exe 和 xml 改名为<code>install-service.exe</code> 和 <code>install-service.xml</code>）</p>
</li>
<li><p>编辑xml 填写相关配置</p>

<title>笔记【一】：MapBox 加载 ArcGIS 的WMS 服务跨域问题解决</title>
<url>/2020/02/22/note-arcgisserver-cors/</url>
<content><![CDATA[<h5 id="1-环境："><a href="#1-环境：" class="headerlink" title="1. 环境："></a>1. 环境：</h5><hr><ul>
<li>ArcGIS Server 10.2</li>
<li>MapBox-GL v 1.7</li>
</ul><h5 id="2-问题描述："><a href="#2-问题描述：" class="headerlink" title="2. 问题描述："></a>2. 问题描述：</h5><hr><p>在使用ArcGIS 发布一个WMS 服务，同时用OpenLayers,LeafLet以及MapBox 加载，在OpenLayers和LeafLet 中均可正常加载，但在MapBox 中加载出现跨域请求现象</p><a id="more"></a>
<p><img src="https://i.loli.net/2020/02/22/vd584MATnaHZB6S.png" alt="跨域报错"></p>
<h5 id="3-产生原因："><a href="#3-产生原因：" class="headerlink" title="3.产生原因："></a>3.产生原因：</h5><hr>
<p>通过查找文档以及Mapbox的GitHub 的issues 找到相关解释：<a href="https://github.com/mapbox/mapbox-gl-js/issues/2171" target="_blank" rel="noopener">原Issue</a></p>
<p><img src="https://i.loli.net/2020/02/22/Is87CR1pvBS3MdD.png" alt="issue"></p>
<p>读下来的大致意思是：mapbox 加载WMS是需要读取 image里的数据，但只有服务器允许跨域的情况下我们才可以这么做。而LeafLet 不需要读取数据，所以可以直接加载。</p>
<p>那么知道产生原因，问题就好解决了。</p>
<h5 id="4-解决方案"><a href="#4-解决方案" class="headerlink" title="4. 解决方案"></a>4. 解决方案</h5><ol>
<li><p>下载 <a href="http://www.java2s.com/Code/Jar/c/Downloadcorsfilter17jar.htm" target="_blank" rel="noopener"><code>cors-filter-1.7.jar</code></a> 以及 <a href="http://www.java2s.com/example/jar/j/download-javapropertyutils19jar-file.html" target="_blank" rel="noopener"><code>java-property-utils-1.9.jar</code></a> 这两个jar 包用于设置Tomcat的跨域。</p>
</li>
<li><p>找到ArcGIS 安装目录下的<code><安装目录>\framework\runtime\tomcat\lib</code> 将下载的jar 拷贝到该目录下<img src="https://i.loli.net/2020/02/22/KELbac8XRJAGTqw.png" alt="新加jar"></p>
</li>
<li><p>修改tomcat配置<code><安装目录>\framework\runtime\tomcat\conf\web.xm</code></p>
</li>
<li><p>找到<code><filter></code> 同级的末尾追加如下XML代码：</p>

<li><p>找到window的服务，重启ArcGIS Server 服务<img src="https://i.loli.net/2020/02/22/duERTZomwyb4krB.png" alt="重启服务"></p>
</li>
<li><p>再次使用Mapbox 请求验证问题，已经可以正常请求到WMS服务。<img src="https://i.loli.net/2020/02/22/pMxzBHC78ZKwJVa.png" alt="效果.png"></p>

<title>OpenLayers 基础 一：了解并简单构建</title>
<url>/2019/11/20/openlayers-start/</url>
<content><![CDATA[<h5 id="一、介绍"><a href="#一、介绍" class="headerlink" title="一、介绍"></a>一、介绍</h5><blockquote>
<p>现在互联网地图（<a href="http://lbsyun.baidu.com/" target="_blank" rel="noopener">百度地图</a>，<a href="https://lbs.amap.com/" target="_blank" rel="noopener">高德地图</a>）都提供了很好的API使用，简单易懂，可以很快的通过文档构建自己的地图显示。但是有些时候项目和产品中需要离线的地图展示，本系列文章只讲述项目中比较常用的一些知识点，不会对每个组件进行详细的介绍。</p>
</blockquote><hr><p>OpenLayers 是一个开源的Web地图库,主要用于在Web段创建可交互式二维地图。本系列以6.0.1的版本进行讲解。</p><a id="more"></a>
<p>官网：<a href="https://openlayers.org/" target="_blank" rel="noopener">OpenLayers</a></p>
<p>源码：<a href="https://github.com/openlayers/openlayers" target="_blank" rel="noopener">GitHub</a></p>
<h5 id="二、核心组件"><a href="#二、核心组件" class="headerlink" title="二、核心组件"></a>二、核心组件</h5><hr>
<p><img src="https://i.loli.net/2019/11/20/soCPGMFzjB7wnLT.png" alt="组件构成"></p>
<ol>
<li>Map:一个入口，用于组织和管理各个组件对象，最后渲染成地图。</li>
<li>View：用于控制地图中心点，显示范围，显示层级等</li>
<li>Layers：主要用于生成不同种类的图层，进行叠加展示</li>
<li>Controls：提供不同种类的交互控件（也可以自定义控件），用来实现用户通过控件和地图交互，或者用于提供一些信息。控件会固定在页面一个位置，不会跟随地图改变而改变位置。</li>
<li>Interactions：用来定义用户和地图交互功能和交互方式。</li>
<li>Sources：数据源，用来给Layers提供源数据，每一个Layers 都会有一个对应的Source用以提供数据。</li>
</ol>

</ol>
<p>这样就可以形成一个简单的地图出来</p>
<p><img src="https://i.loli.net/2019/11/20/ObCEkrVJlRALqtv.png" alt="地图"></p>
<hr>
<h5 id="四、总结"><a href="#四、总结" class="headerlink" title="四、总结"></a>四、总结</h5><p>通过上面的 <em>快速开始</em> 可以看出，构建一个地图需要的必备属性：</p>
<ul>
<li>target ：地图容器的DIV</li>
<li>view ：视图控制地图层级和中心点</li>
<li>layers ：地图图层</li>
</ul>
<p>只要这三个部分组织完毕，一个基本的地图应用就可以使用了。</p>
