Detailed Description

This feature renderer can translate all the predefined geometries of Rogue Wave Views into graphic objects.

Library: ilvmaps

It dispatches the makeGraphic() calls to a specialized feature renderer depending on the geometry of the map feature. Each specialized feature renderer is initialized with a default value, but it can be changed.

This renderer uses a parameter file S57Styles.txt to specify the visibility, the background color, foreground color, the filling, the stroke, the stroke style and the bitmap of the different classes of S57 format. You can modify this file which is located in ILVHOME/data/maps/s57. You can also create your own version of S57Styles.txt in another directory specified by the ILVMAPSS57STYLES environment variable. However if you use this last method, the new directory must contain all necessary bitmaps which are defined in S57Styles.txt. For the syntax, see the original file.

Note: If a class of S57 is specified as 'not visible', the makeGraphic() and dispatch() functions will return a null object.

By default the IlvS57Loader class uses this renderer.

◆ IlvS57Renderer()

IlvS57Renderer::IlvS57Renderer ( IlvDisplay * display )

Initializes a new instance of the renderer.

Parameters

display The display used to create the graphic objects.

Member Function Documentation

◆ dispatch()

virtual IlvGraphic* IlvS57Renderer::dispatch	(	const IlvMapFeature &	mapFeature,
		const IlvMapInfo &	targetMapInfo,
		IlvMapsError &	status
	)		const

protectedvirtual

Dispatches a map feature to the renderer specialized to render the feature geometry.

Parameters

mapFeature	The map feature to be translated.
targetMapInfo	The `IlvMapInfo` that specifies the projection in which the graphic object must be returned.
status	Set to an error code if the renderer cannot process the map feature.

Returns: An IlvGraphic or 0 if no appropriate renderer was found, or if a severe error occurs during the rendering process.
