Detailed Description

This renderer translates a map feature whose geometry is an IlvMapPoint into an IlvIcon.

Library: ilvmaps

Constructor & Destructor Documentation

IlvIconPointRenderer() [1/2]

IlvIconPointRenderer::IlvIconPointRenderer

(

IlvDisplay *

display

)

Creates an instance of the renderer.

Parameters

display

The IlvDisplay used to create the graphic objects.

IlvIconPointRenderer() [2/2]

IlvIconPointRenderer::IlvIconPointRenderer

(

const IlvIconPointRenderer &

source

)

Creates an IlvIconPointRenderer by copying an existing one.

Parameters

source

The object to be copied.

Member Function Documentation

getBitmap()

IlvBitmap* IlvIconPointRenderer::getBitmap

(

)

const

Returns the bitmap used by the renderer.

Returns

An IlvBitmap object that should not be deleted. However, it can be locked if an other object has to use it.

See also

IlvResource::lock, IlvResource::unLock.

GetDefaultBitmap()

static IlvBitmap* IlvIconPointRenderer::GetDefaultBitmap ( IlvDisplay *  display )

static

Returns the default bitmap used by the renderer if no bitmap has been specified.

Returns

An IlvBitmap object that should not be deleted. However, it can be locked if an other object has to use it.

See also

IlvResource::lock, IlvResource::unLock.

makeGraphic()

virtual IlvGraphic* IlvIconPointRenderer::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.

setBitmap()

void IlvIconPointRenderer::setBitmap

(

IlvBitmap *

bitmap

)

Sets the bitmap used by this renderer.

Parameters

bitmap

The bitmap to be set.

setBitmapFileName()

IlvMapsError IlvIconPointRenderer::setBitmapFileName

(

const char *

fileName

)

Sets the bitmap used by this renderer by specifying a file name.

Parameters

fileName

The name of the file containing the bitmap.

Returns

An IlvMapError code if fileName is not a valid bitmap file name.
