## 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="XLink namespace"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
      
      <NamedLayer>
        <Name>default_polygon</Name>
        <UserStyle>
        
          <Title>Default Polygon</Title>
          <Abstract>A sample style that draws a polygon</Abstract>
          
          
          <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

![watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBA6Zy46YGT5rWB5rCT5rCU6LSo_size_18_color_FFFFFF_t_70_g_se_x_16][]

5、设置透明度之后

![watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBA6Zy46YGT5rWB5rCT5rCU6LSo_size_18_color_FFFFFF_t_70_g_se_x_16 1][]
