Detailed Description

This renderer translates a map feature whose geometry is an IlvMapImage into an IlvZoomableIcon.

Library: ilvmaps

Constructor & Destructor Documentation

IlvDefaultImageRenderer::IlvDefaultImageRenderer ( IlvDisplay * display )

Creates an instance of the renderer.

Parameters

display The display used to create the graphic objects.

IlvDefaultImageRenderer::IlvDefaultImageRenderer ( const IlvDefaultImageRenderer & source )

Creates a renderer by copying an existing one.

Parameters

source The object to be copied.

static IlvMapsError IlvDefaultImageRenderer::BitmapError ( )

static

The error code returned if an error occurred during the bitmap data creation.

Returns: An IlvMapsError returned if an error occurred during the bitmap data creation.

IlvGraphic* IlvDefaultImageRenderer::makeGraphic	(	const IlvMapFeature &	feature,
		const IlvMapInfo &	targetMapInfo,
		IlvMapsError &	status
	)		const

virtual

Translates an IlvMapFeature into a graphic object.

Parameters

feature	The map feature to be translated.
targetMapInfo	The target map info.
status	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 object or a null pointer if a severe error occurred.
