实现

1、以下为一个style的示例

<?xml version="1.0" encoding="UTF-8"?>
<StyledLayerDescriptor version="1.0.0"
 xsi:schemaLocation="http://www.opengis.net/sld StyledLayerDescriptor.xsd"
 xmlns="http://www.opengis.net/sld"
 xmlns:ogc="http://www.opengis.net/ogc"
 xmlns:xlink="http://www.w3.org/1999/xlink"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <!-- a Named Layer is the basic building block of an SLD document -->
  <NamedLayer>
    <Name>default_polygon</Name>
    <UserStyle>
    <!-- Styles can have names, titles and abstracts -->
      <Title>Default Polygon</Title>
      <Abstract>A sample style that draws a polygon</Abstract>
      <!-- FeatureTypeStyles describe how to render different features -->
      <!-- A FeatureTypeStyle for rendering polygons -->
      <FeatureTypeStyle>
        <Rule>
          <Name>rule1</Name>
          <Title>Gray Polygon with Black Outline</Title>
          <Abstract>A polygon with a gray fill and a 1 pixel black outline</Abstract>
          <PolygonSymbolizer>
            <Fill>
              <CssParameter name="fill">#AAAAAA</CssParameter>
     <CssParameter name="fill-opacity">0.3</CssParameter>
            </Fill>
            <Stroke>
              <CssParameter name="stroke">#CCCCCC</CssParameter>
              <CssParameter name="stroke-width">1</CssParameter>
            </Stroke>
          </PolygonSymbolizer>
        </Rule>
      </FeatureTypeStyle>
    </UserStyle>
  </NamedLayer>
</StyledLayerDescriptor>

2、其中设置填充的颜色和填充颜色的透明度

            <Fill>
              <CssParameter name="fill">#AAAAAA</CssParameter>
              <CssParameter name="fill-opacity">0.3</CssParameter>
            </Fill>

3、设置边界颜色与宽度

            <Stroke>
              <CssParameter name="stroke">#CCCCCC</CssParameter>
              <CssParameter name="stroke-width">1</CssParameter>
            </Stroke>

4、设置透明度之前

 

5、设置透明度之后
