Constructor & Destructor Documentation

GeoTIFFMapChartDataSource()

disti::GeoTIFFMapChartDataSource::GeoTIFFMapChartDataSource

(

)

Create a new GlsMapGeoTIFF.

~GeoTIFFMapChartDataSource()

disti::GeoTIFFMapChartDataSource::~GeoTIFFMapChartDataSource

(

)

Member Function Documentation

GetAvailableCoverage()

bool disti::GeoTIFFMapChartDataSource::GetAvailableCoverage ( GeoRect *  dest )

virtual

See base class.

Implements disti::GlsMapChartDataSource.

GetCellList()

void disti::GeoTIFFMapChartDataSource::GetCellList ( const GeoRect &  coverage, unsigned long  layerID, double  viewLogicalHeight, double  viewGeoHeight, MapChartCellList &  viewList  )

virtual

See base class.

Implements disti::GlsMapChartDataSource.

GetTargetCellLoadRate()

double disti::GeoTIFFMapChartDataSource::GetTargetCellLoadRate

(

)

const

Get the target rate in hz at which cells will be loaded

Returns

target rate in hz else 0.0 for no target rate ( i.e. load as quickly as possible )

LoadGeoTIFF()

void disti::GeoTIFFMapChartDataSource::LoadGeoTIFF

(

const std::string &

str

)

Load one or more GeoTIFF images.

Parameters

str	A string containing one filename, a comma separated list of filenames a directory to parse, recursively, looking for files to load.

SetCacheCount()

void disti::GeoTIFFMapChartDataSource::SetCacheCount

(

const unsigned int

cacheCount

)

Set the count of the layer cache

Parameters

cacheCount

max number of layers to cache else 0u to disable layer caching

SetTargetCellLoadRate()

void disti::GeoTIFFMapChartDataSource::SetTargetCellLoadRate

(

const double

targetCellLoadRate

)

Set the target rate in hz at which cells will be loaded

Parameters

targetCellLoadRate

target rate in hz else 0.0 for no target rate ( i.e. load as quickly as possible )

UnloadGeoTIFF()

void disti::GeoTIFFMapChartDataSource::UnloadGeoTIFF

(

const std::string &

str

)

Unload one or more GeoTIFF images.

Parameters

str	Must be the same string passed to LoadGeoTIFF
