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

)

Parameters:

source

The object to be copied.

Member Function Documentation

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.

makeGraphic

virtual IlvFeatureRenderer* IlvDefaultImageRenderer::copy

(

)

const [virtual]

Copies the object.

Returns:

A copy of this IlvFeatureRenderer.

Implements IlvFeatureRenderer.

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

Translates an IlvMapFeature into a graphic object.

Warning:

This renderer handles projection conversion.

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.

Implements IlvFeatureRenderer.

virtual void IlvDefaultImageRenderer::write

(

IlvOutputFile &

file

)

const [virtual]

Writes the renderer to an IlvOutputStream.

This function must be reimplemented by the subclasses of IlvFeatureRenderer, but it should not be called directly by the application. For more information about subclassing an IlvFeatureRenderer, refer to the User Manual of Rogue Wave Views Maps.

Parameters:

file

The output file.
