A repeated linear graphic is plotted linearly and has its graphic symbol bent around the curves of the line string. A GraphicFill has the pixels of the line rendered with a repeating area-fill pattern.<p> If neither a graphic fill nor graphic stroke element are given, then the line symbolizer should render a solid color. <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="Stroke"> <xsd:annotation> <xsd:documentation> A "Stroke" specifies the appearance of a linear geometry. It is defined in parallel with SVG strokes. The following CssParameters may be used: "stroke" (color), "stroke-opacity", "stroke-width", "stroke-linejoin", "stroke-linecap", "stroke-dasharray", and "stroke-dashoffset". </xsd:documentation> </xsd:annotation> <xsd:complexType> <xsd:sequence> <xsd:choice minOccurs="0"> <xsd:element ref="sld:GraphicFill"/> <xsd:element ref="sld:GraphicStroke"/> </xsd:choice> <xsd:element ref="sld:CssParameter" minOccurs="0" maxOccurs="unbounded"/> </xsd:sequence> </xsd:complexType> </xsd:element> </code></pre> <p> 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. <p> Notes: <ul> <li>The graphical parameters and their values are derived from SVG/CSS2 standards with names and semantics which are as close as possible.
