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.

/warning [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.

Constructor & Destructor Documentation

IlvS57Renderer::IlvS57Renderer ( IlvDisplay display)

Initializes an instance of the renderer.

Parameters
displayThe display used to create the graphic objects.

Member Function Documentation

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
mapFeatureThe map feature to be translated.
targetMapInfoThe IlvMapInfo that specifies the projection in which the graphic object must be returned.
statusSet 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.

Reimplemented from IlvDefaultFeatureRenderer.
