Detailed Description

This feature renderer can translate all the predefined geometries of Rogue Wave Views into graphic objects.

Library: ilvmaps

It dispatches the makeGraphic() calls to a specialized feature renderer depending on the geometry of the map feature. Each specialized feature renderer is initialized with a default value, but it can be changed.

Constructor & Destructor Documentation

§ IlvDefaultFeatureRenderer() [1/2]

IlvDefaultFeatureRenderer::IlvDefaultFeatureRenderer ( IlvDisplay * display )

Initializes an instance of the renderer.

Parameters

display The display used to create the graphic objects.

§ IlvDefaultFeatureRenderer() [2/2]

IlvDefaultFeatureRenderer::IlvDefaultFeatureRenderer ( const IlvDefaultFeatureRenderer & source )

Initializes an IlvDefaultFeatureRenderer by copying an existing one.

Parameters

source The renderer to be copied.

Member Function Documentation

§ dispatch()

virtual IlvGraphic* IlvDefaultFeatureRenderer::dispatch	(	const IlvMapFeature &	mapFeature,
		const IlvMapInfo &	targetMapInfo,
		IlvMapsError &	status
	)		const

protectedvirtual

Dispatches a map feature to the renderer specialized to render the feature geometry.

Parameters

mapFeature	The map feature to be translated.
targetMapInfo	The `IlvMapInfo` that specifies the projection in which the graphic object must be returned.
status	Set to an error code if the renderer cannot process the map feature.

Returns: An IlvGraphic or 0 if no appropriate renderer was found, or if a severe error occurs during the rendering process.

Reimplemented in IlvS57Renderer.

§ getAreaRenderer()

IlvFeatureRenderer* IlvDefaultFeatureRenderer::getAreaRenderer ( ) const

Returns the renderer used to translate areas into graphic objects.

Returns: An IlvFeatureRenderer that can be modified, but that should not be deleted.

§ getCurveRenderer()

IlvFeatureRenderer* IlvDefaultFeatureRenderer::getCurveRenderer ( ) const

Returns the renderer used to translate curves into graphic objects.

Returns: An IlvFeatureRenderer that can be modified, but that should not be deleted.

§ getImageRenderer()

IlvFeatureRenderer* IlvDefaultFeatureRenderer::getImageRenderer ( ) const

Returns the renderer used to translate images into graphic objects.

Returns: An IlvFeatureRenderer that can be modified, but that should not be deleted.

§ getPointRenderer()

IlvFeatureRenderer* IlvDefaultFeatureRenderer::getPointRenderer ( ) const

Returns the renderer used to translate points into graphic objects.

Returns: An IlvFeatureRenderer that can be modified, but that should not be deleted.

§ getRasterRenderer()

IlvFeatureRenderer* IlvDefaultFeatureRenderer::getRasterRenderer ( ) const

Returns the renderer used to translate rasters into graphic objects.

Returns: An IlvFeatureRenderer that can be modified, but that should not be deleted.

§ getTextRenderer()

IlvFeatureRenderer* IlvDefaultFeatureRenderer::getTextRenderer ( ) const

Returns The renderer used to translate texts into graphic objects.

Returns: An IlvFeatureRenderer that can be modified, but that should not be deleted.

§ makeGraphic()

virtual IlvGraphic* IlvDefaultFeatureRenderer::makeGraphic	(	const IlvMapFeature &	mapFeature,
		const IlvMapInfo &	targetMapInfo,
		IlvMapsError &	status
	)		const

virtual

Translates an IlvMapFeature into a graphic object.

If the targetMapInfo has a non-null projection, or a projection that is not an instance of IlvUnknownProjection, the graphic object is projected to the projection system of targetMapInfo. Otherwise, only the map adapter of targetMapInfo is used to convert the feature coordinate into the manager coordinate system.

Parameters

mapFeature	The map feature to be translated.
targetMapInfo	This parameter specifies the projection in which the graphic object must be returned. If this projection is not defined (`targetMapInfo.getProjection()` is `0`), the graphic object is returned to the projection of the map feature (only the map adapter is used)
status	Is set to an error code if the renderer cannot process the map feature (most of the time, because the renderer does not support the feature geometry, but it can also indicate that a projection error occurred).

Returns: An IlvGraphic or 0 if a severe error occurred.

Implements IlvFeatureRenderer.

§ makeGraphicFromGeometryCollection()

virtual IlvGraphic* IlvDefaultFeatureRenderer::makeGraphicFromGeometryCollection	(	const IlvMapFeature &	mapFeature,
		const IlvMapInfo &	targetMapInfo,
		IlvMapsError &	status
	)		const

protectedvirtual

This function is called by dispatch for the map features whose geometry is a collection of subgeometries.

Parameters

mapFeature	The map feature to be translated.
targetMapInfo	The `IlvMapInfo` that specifies the projection in which the graphic object must be returned.
status	Set to an error code if the renderer cannot process the map feature.

Returns: An IlvGraphic or 0 if no appropriate renderer was found, or if a severe error occurs during the rendering process.

§ setAreaRenderer()

void IlvDefaultFeatureRenderer::setAreaRenderer ( const IlvFeatureRenderer * areaRndr )

Sets the graphic renderer used to translate areas into graphic objects.

Parameters

areaRndr The area renderer.

§ setCurveRenderer()

void IlvDefaultFeatureRenderer::setCurveRenderer ( const IlvFeatureRenderer * curveRndr )

Sets the graphic renderer used to translate curves into graphic objects.

Parameters

curveRndr The curve renderer.

§ setImageRenderer()

void IlvDefaultFeatureRenderer::setImageRenderer ( const IlvFeatureRenderer * imageRndr )

Sets the graphic renderer used to translate images into graphic objects.

Parameters

§ setPointRenderer()

void IlvDefaultFeatureRenderer::setPointRenderer ( const IlvFeatureRenderer * pointRndr )

Sets the graphic renderer used to translate points into graphic objects.

Parameters

pointRndr The point renderer.

§ setRasterRenderer()

void IlvDefaultFeatureRenderer::setRasterRenderer ( const IlvFeatureRenderer * rasterRndr )

Sets the graphic renderer used to translate rasters into graphic objects.

Parameters

rasterRndr The raster renderer.

§ setTextRenderer()

void IlvDefaultFeatureRenderer::setTextRenderer ( const IlvFeatureRenderer * textRndr )

Sets the graphic renderer used to translate texts into graphic objects.

Parameters

textRndr The text renderer.
