This class is an IlvTileLoader specialized for reading GeoTIFF files.

Library: ilvmaps

This class inherits most of its behaviors from an IlvMapTileLoader.

Member Function Documentation

virtual IlvFeatureRenderer* IlvGeoTIFFTileLoader::getDefaultFeatureRenderer ( IlvDisplay display)
virtual

Returns the default feature renderer used for the rendering of map features of the current tile.

This default feature renderer is used when the user does not set a feature renderer.

Parameters
displayThe IlvDisplay
Returns
The default feature renderer.

Implements IlvMapTileLoader.

virtual IlvMapFeatureIterator* IlvGeoTIFFTileLoader::getFeatureIterator ( IlvTile tile)
virtual

Returns the feature iterator to read features for the specified tile.

Parameters
tileThe tile to load.
Returns
The feature iterator to load features for this tile, or 0 if no features are to be loaded.

Implements IlvMapTileLoader.

virtual IlvRect& IlvGeoTIFFTileLoader::getTileOrigin ( )
virtual

Returns the tile origin.

Returns
The tile origin.
virtual IlBoolean IlvGeoTIFFTileLoader::isPersistent ( ) const
virtual

Returns IlTrue if this tile loader must be saved by a tile controller.

Returns
IlTrue if this tile loader must be saved.

Implements IlvMapTileLoader.
