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() [1/2]

IlvDefaultAreaRenderer::IlvDefaultAreaRenderer

(

IlvDisplay *

display

)

Initializes a new IlvDefaultAreaRenderer instance.

Parameters

display

The display used to create the graphic objects.

IlvDefaultAreaRenderer() [2/2]

IlvDefaultAreaRenderer::IlvDefaultAreaRenderer

(

const IlvDefaultAreaRenderer &

source

)

Initializes a new IlvDefaultAreaRenderer instance as a copy of another one.

Parameters

source

The object to be copied.

Member Function Documentation

getAreaRenderingStyle()

IlvMapAreaRenderingStyle* IlvDefaultAreaRenderer::getAreaRenderingStyle

(

)

const

Returns the area rendering style.

Returns

The IlvMapAreaRenderingStyle of this renderer.

makeGraphic()

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

feature	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 NULL), 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 a null pointer if a severe error occurred.

Implements IlvFeatureRenderer.

setAreaRenderingStyle()

void IlvDefaultAreaRenderer::setAreaRenderingStyle

(

IlvMapAreaRenderingStyle *

areaRenderingStyle

)

Sets the rendering style for the areas.

Parameters

areaRenderingStyle

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