Detailed Description

Simple renderer that does nothing.

All required callback methods are implemented in one of the following ways:

• Signal that Feature not implemented
• Does nothing if this does not influence the rendering algorithms
• Return some sensible default, if required

Member Function Documentation

DrawArea()

void osmscout::MapPainterNoOp::DrawArea ( const Projection &  projection, const MapParameter &  parameter, const AreaData &  area  )

overrideprotectedvirtual

Draw the given area using the given FillStyle for the area outline.

Implements osmscout::MapPainter.

DrawContourSymbol()

void osmscout::MapPainterNoOp::DrawContourSymbol ( const Projection &  projection, const MapParameter &  parameter, const Symbol &  symbol, const ContourSymbolData &  data  )

overrideprotectedvirtual

Draw the given Symbol on top of the contour of the given path.

Implements osmscout::MapPainter.

DrawGround()

void osmscout::MapPainterNoOp::DrawGround ( const Projection &  projection, const MapParameter &  parameter, const FillStyle &  style  )

overrideprotectedvirtual

(Optionally) fills the area with the given default color for ground.

In 2D backends this just fills the given area, 3D backends might draw a sphere or an infinite plane.

Implements osmscout::MapPainter.

DrawIcon()

void osmscout::MapPainterNoOp::DrawIcon ( const IconStyle *  style, const Vertex2D &  centerPos, double  width, double  height  )

overrideprotectedvirtual

Draw the Icon as defined by the IconStyle at the given pixel coordinate (icon center).

Implements osmscout::MapPainter.

DrawLabels()

void osmscout::MapPainterNoOp::DrawLabels ( const Projection &  projection, const MapParameter &  parameter, const std::vector< MapData > &  data  )

overrideprotectedvirtual

Implements osmscout::MapPainter.

DrawMap()

bool osmscout::MapPainterNoOp::DrawMap	(	const Projection &	projection,
		const MapParameter &	parameter,
		const std::vector< MapData > &	data,
		RenderSteps	startStep = RenderSteps::FirstStep,
		RenderSteps	endStep = RenderSteps::LastStep
	)

DrawPath()

void osmscout::MapPainterNoOp::DrawPath ( const Projection &  projection, const MapParameter &  parameter, const Color &  color, double  width, const std::vector< double > &  dash, LineStyle::CapStyle  startCap, LineStyle::CapStyle  endCap, const CoordBufferRange &  coordRange  )

overrideprotectedvirtual

Draw simple line with the given style,the given color, the given width and the given untransformed nodes.

Implements osmscout::MapPainter.

DrawSymbol()

void osmscout::MapPainterNoOp::DrawSymbol ( const Projection &  projection, const MapParameter &  parameter, const Symbol &  symbol, const Vertex2D &  screenPos, double  scaleFactor  )

overrideprotectedvirtual

Draw the Symbol as defined by the SymbolStyle at the given pixel coordinate (symbol center).

Implements osmscout::MapPainter.

GetFontHeight()

double osmscout::MapPainterNoOp::GetFontHeight ( const Projection &  projection, const MapParameter &  parameter, double  fontSize  )

overrideprotectedvirtual

Returns the height of the font.

Implements osmscout::MapPainter.

References osmscout::FONT_HEIGHT_FACTOR.

HasIcon()

bool osmscout::MapPainterNoOp::HasIcon ( const StyleConfig &  styleConfig, const Projection &  projection, const MapParameter &  parameter, IconStyle &  style  )

overrideprotectedvirtual

Return true, if the icon in the IconStyle is available and can be drawn.

If this method returns false, possibly a fallback (using a Symbol) will be chosen.

Icon style dimensions and iconId may be setup for later usage.

Implements osmscout::MapPainter.

RegisterContourLabel()

void osmscout::MapPainterNoOp::RegisterContourLabel ( const Projection &  projection, const MapParameter &  parameter, const ObjectFileRef &  ref, const PathLabelData &  label, const LabelPath &  labelPath  )

overrideprotectedvirtual

Register contour label.

Implements osmscout::MapPainter.

RegisterRegularLabel()

void osmscout::MapPainterNoOp::RegisterRegularLabel ( const Projection &  projection, const MapParameter &  parameter, const ObjectFileRef &  ref, const std::vector< LabelData > &  labels, const Vertex2D &  position, double  objectWidth  )

overrideprotectedvirtual

Register regular label with given text at the given pixel coordinate in a style defined by the given LabelStyle.

Implements osmscout::MapPainter.
