Detailed Description

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

Library: ilvmaps

Constructor & Destructor Documentation

IlvIconPointRenderer::IlvIconPointRenderer ( IlvDisplay display)

Creates an instance of the renderer.

Parameters
displayThe IlvDisplay used to create the graphic objects.
IlvIconPointRenderer::IlvIconPointRenderer ( const IlvIconPointRenderer source)

Creates an IlvIconPointRenderer by copying an existing one.

Parameters
sourceThe object to be copied.

Member Function Documentation

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.
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.
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
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 IlvIconPointRenderer::setBitmap ( IlvBitmap bitmap)

Sets the bitmap used by this renderer.

Parameters
bitmapThe bitmap to be set.
IlvMapsError IlvIconPointRenderer::setBitmapFileName ( const char *  fileName)

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

Parameters
fileNameThe name of the file containing the bitmap.
Returns
An IlvMapError code if fileName is not a valid bitmap file name.
