void te::se::LineSymbolizer::setGeometry ( te::fe::PropertyName * geometry )

The Geometry element of a LineSymbolizer defines the linear geometry to be used for styling. The Geometry element is optional and if it is absent then the all geometry properties of the feature type that is used in the containing FeatureType are used. Most frequently, though, feature types will have only a single geometry property. See OGC te::fe::PropertyName class for more information on attribute names.

Note: Geometry types other than inherently linear types can also be used. If a point geometry is used, it should be interpreted as a line of "epsilon" (arbitrarily small) length with a horizontal orientation centered on the point, and should be rendered with two end caps. If a polygon is used (or other "area" type), then its closed outline is used as the line string (with no end caps). If a raster geometry is used, its coverage-area outline is used for the line, rendered with no end caps.

void te::se::LineSymbolizer::setPerpendicularOffset ( ParameterValue * perpendicularOffset )

PerpendicularOffset allows to draw lines in parallel to the original geometry. For complex line strings these parallel lines have to be constructed so that the distance between original geometry and drawn line stays equal. This construction can result in drawn lines that are actually smaller or longer than the original geometry. The distance is in uoms and is positive to the left-hand side of the line string. Negative numbers mean right. The default offset is 0.

void te::se::LineSymbolizer::setStroke ( Stroke * stroke )

A Stroke specifies the appearance of a linear geometry. The Stroke element is optional inside of LineSymbolizer (and other Symbolizers), and its absence means that no stroke is to be rendered.

void te::se::Symbolizer::setUom ( const te::common::BaseUnitOfMeasure * uom )

inherited

It sets the unit-of-measure.

All Symbolizers include an optional gml:uom-attribute as used by GML (this is set inside the abstract SymbolizerType and therefore inherited by all Symbolizers). This applies to all elements included inside a Symbolizer such as stroke-width, size, font-size, Gap, InitialGap, Displacement and PerpendicularOffset. If no uom is set inside of Symbolizer, all units are measured in pixel, the behaviour used by SLD 1.0.0. The following uom definitions are recommended to be used:
