Fill介绍

[英]The Fill object encapsulates the graphical-symbolization parameters for areas of geometries.

There are two types of fill: solid-color and repeated graphic fill.

The details of this object are taken from the OGC Styled-Layer Descriptor Report (OGC 02-070) version 1.0.0.:

<xsd:element name="Fill"> 
<xsd:annotation> 
<xsd:documentation> 
A "Fill" specifies the pattern for filling an area geometry. 
The allowed CssParameters are: "fill" (color) and "fill-opacity". 
</xsd:documentation> 
</xsd:annotation> 
<xsd:complexType> 
<xsd:sequence> 
<xsd:element ref="sld:GraphicFill" minOccurs="0"/> 
<xsd:element ref="sld:CssParameter" minOccurs="0" 
maxOccurs="unbounded"/> 
</xsd:sequence> 
</xsd:complexType> 
</xsd:element>

Renderers can use this information when displaying styled features, though it must be remembered that not all renderers will be able to fully represent strokes as set out by this interface. For example, opacity may not be supported.

Notes:

• The graphical parameters and their values are derived from SVG/CSS2 standards with names and semantics which are as close as possible.
  [中]填充对象封装了几何图形区域的图形符号化参数。
  有两种类型的填充：纯色和重复图形填充。
  此对象的详细信息取自OGC Styled-Layer Descriptor Report (OGC 02-070) version 1.0.0.：

<xsd:element name="Fill"> 
<xsd:annotation> 
<xsd:documentation> 
A "Fill" specifies the pattern for filling an area geometry. 
The allowed CssParameters are: "fill" (color) and "fill-opacity". 
</xsd:documentation> 
</xsd:annotation> 
<xsd:complexType> 
<xsd:sequence> 
<xsd:element ref="sld:GraphicFill" minOccurs="0"/> 
<xsd:element ref="sld:CssParameter" minOccurs="0" 
maxOccurs="unbounded"/> 
</xsd:sequence> 
</xsd:complexType> 
</xsd:element>

渲染器可以在显示样式化特征时使用此信息，但必须记住，并非所有渲染器都能够完全表示此接口设置的笔划。例如，不透明度可能不受支持。
笔记：
*图形参数及其值源自SVG/CSS2标准，其名称和语义尽可能接近。
