Detailed Description

This renderer translates a map feature whose geometry is a predefined subclass of IlvMapArea into an IlvMapGeneralPath or into an IlvGraphicSet or IlvMapGeneralPath if the geometry is an IlvMapMultiArea.

Library: ilvmaps

Constructor & Destructor Documentation

IlvDefaultAreaRenderer::IlvDefaultAreaRenderer ( IlvDisplay display)

Initializes an instance of the renderer.

Parameters
displayThe display used to create the graphic objects.
IlvDefaultAreaRenderer::IlvDefaultAreaRenderer ( const IlvDefaultAreaRenderer source)

Copies this renderer.

Parameters
sourceThe object to be copied.

Member Function Documentation

IlvMapAreaRenderingStyle* IlvDefaultAreaRenderer::getAreaRenderingStyle ( ) const

Returns the area rendering style.

Returns
The IlvMapAreaRenderingStyle of this renderer.
virtual IlvGraphic* IlvDefaultAreaRenderer::makeGraphic ( const IlvMapFeature feature,
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
featureThe map feature to be translated.
targetMapInfoThis parameter specifies the projection in which the graphic object must be returned. If this projection is not defined (targetMapInfo.getProjection() is NULL), the graphic object is returned to the projection of the map feature (only the map adapter is used)
statusIs 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 a null pointer if a severe error occurred.

Implements IlvFeatureRenderer.

void IlvDefaultAreaRenderer::setAreaRenderingStyle ( IlvMapAreaRenderingStyle areaRenderingStyle)

Sets the rendering style for the areas.

Parameters
areaRenderingStyleThe area rendering style. This object can be shared by other objects.
