Member Function Documentation

QColor QgsOgcUtils::colorFromOgcFill ( const QDomElement fillElement)
static

Parse XML with OGC fill into QColor.

Definition at line 1426 of file qgsogcutils.cpp.

QgsExpression * QgsOgcUtils::expressionFromOgcFilter ( const QDomElement element)
static

Parse XML with OGC filter into QGIS expression.

Definition at line 1465 of file qgsogcutils.cpp.

QDomElement QgsOgcUtils::expressionToOgcFilter ( const QgsExpression exp,
QDomDocument doc,
QString errorMessage = nullptr 
)
static

Creates OGC filter XML element.

Supports minimum standard filter according to the OGC filter specs (=,!=,<,>,<=,>=,AND,OR,NOT)

Returns
valid
<Filter> 
QDomElement on success, otherwise null QDomElement

Definition at line 1910 of file qgsogcutils.cpp.

QgsGeometry * QgsOgcUtils::geometryFromGML ( const QString xmlString)
static

Static method that creates geometry from GML.

Parameters
xmlStringxml representation of the geometry. GML elements are expected to be in default namespace (
{<Point>...</Point> 
) or in "gml" namespace (
<gml:Point>...</gml:Point> 
)

Definition at line 97 of file qgsogcutils.cpp.

QgsGeometry * QgsOgcUtils::geometryFromGML ( const QDomNode geometryNode)
static

Static method that creates geometry from GML.

Definition at line 36 of file qgsogcutils.cpp.

QDomElement QgsOgcUtils::geometryToGML ( const QgsGeometry geometry,
QDomDocument doc,
const QString format,
int  precision = 17 
)
static

Exports the geometry to GML2 or GML3.

Returns
QDomElement

Definition at line 1069 of file qgsogcutils.cpp.

QDomElement QgsOgcUtils::geometryToGML ( const QgsGeometry geometry,
QDomDocument doc,
int  precision = 17 
)
static
