The term graphic is used since the term "symbol" is similar to "symbolizer" which is used in a difference context in SLD. The graphical symbol to display can be provided either as an external graphical resource or as a Mark.<br> Multiple external URLs and marks can be referenced with the proviso that they all provide equivalent graphics in different formats. The 'hot spot' to use for positioning the rendering at a point must either be inherent from the external format or be defined to be the "central point" of the graphic. </p> <p> The details of this object are taken from the <a href="https://portal.opengeospatial.org/files/?artifact_id=1188"> OGC Styled-Layer Descriptor Report (OGC 02-070) version 1.0.0.</a>: <pre><code> <xsd:element name="Graphic"> <xsd:annotation> <xsd:documentation> A "Graphic" specifies or refers to a "graphic symbol" with inherent shape, size, and coloring. </xsd:documentation> </xsd:annotation> <xsd:complexType> <xsd:sequence> <xsd:choice minOccurs="0" maxOccurs="unbounded"> <xsd:element ref="sld:ExternalGraphic"/> <xsd:element ref="sld:Mark"/> </xsd:choice> <xsd:sequence> <xsd:element ref="sld:Opacity" minOccurs="0"/> <xsd:element ref="sld:Size" minOccurs="0"/> <xsd:element ref="sld:Rotation" minOccurs="0"/> </xsd:sequence> </xsd:sequence> </xsd:complexType> </xsd:element> </code></pre> </p> <p> Renderers can ue 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.
