Member Function Documentation

◆ AddFile()

bool ECWDataSet::AddFile ( const std::string &  filename)
virtual

Set filename. The ECW Dataset class assumes that each dataset contains only one file. the RasterMosaicer will make separate datasets for each file.

Implements Maria::RasterDataSet.

◆ BuildRaster()

MosaicResult ECWDataSet::BuildRaster ( const RasterMosaicer &  mosaic,
Maria::GeoBitmap &  data,
std::shared_ptr< Maria::RasterProjector >  vp,
double  nominalScale 
)
virtual

Cut out an image for the area defined by the given viewport. This method should reproject and cut the input data to the projection and limits defined by the viewport.

Implements Maria::RasterDataSet.

◆ BuildRasterTile()

MosaicResult ECWDataSet::BuildRasterTile ( const RasterMosaicer &  mosaic,
Maria::GeoBitmap &  data,
Maria::TileId  tileId,
const Maria::TileCacheSpec &  tcs 
)
virtual

Get an image tile for the given tiling and tileId. This method should only be used for tiled data sets.

Implements Maria::RasterDataSet.

◆ CalcBoundingBox()

RectD ECWDataSet::CalcBoundingBox ( const std::shared_ptr< Maria::IProjector > &  pj)
virtual

Calculate bounding box in the given coordinate system.If the given coordinate system is null, the native coordinate system should be used.

Implements Maria::RasterDataSet.

◆ CalcResolutionArea()

bool ECWDataSet::CalcResolutionArea ( Maria::ResolutionArea &  resArea)
virtual

Calculate max resolution and bounding box for the data set in the given projection.

Implements Maria::RasterDataSet.

◆ Close()

void ECWDataSet::Close ( )
virtual

Close dataset. This method should free up all data structures used by the data set.

Implements Maria::RasterDataSet.

◆ ContainsTile()

bool ECWDataSet::ContainsTile ( Maria::TileId  tileId,
const Maria::TileCacheSpec &  tcs 
)
virtual

Check if dataset contains the given tile ID for the given tiling. This method should only be used for tiled data sets.

Implements Maria::RasterDataSet.

◆ GetProjector()

std::shared_ptr< Maria::IProjector > ECWDataSet::GetProjector ( )
virtual

Get the projection for this dataset. Return a projector for the native coordinate system of this dataset. If no projection is given WGS84 lat/lon is assumed.

Implements Maria::RasterDataSet.

◆ IsActive()

bool ECWDataSet::IsActive ( )
virtual

Check if dataset is in use. This indicates that the dataset has loaded data into memory.

Implements Maria::RasterDataSet.
