Constructor & Destructor Documentation

~IRaster()

virtual HydroCouple::Spatial::IRaster::~IRaster ( )

pure virtual

IRaster destructor.

Member Function Documentation

addRasterBand()

virtual void HydroCouple::Spatial::IRaster::addRasterBand ( RasterDataType  dataType )

pure virtual

Adds a new IRasterBand.

geoTransformation()

virtual void HydroCouple::Spatial::IRaster::geoTransformation ( double *  transformationMatrix )

pure virtual

Fetches the affine transformation coefficients. It is an array of size 6.

Fetches the coefficients for transforming between pixel/line (P,L) raster space, and projection coordinates (Xp,Yp) space. Xp = transformationMatrix[0] + P*transformationMatrix[1] + L*transformationMatrix[2]; Yp = transformationMatrix[3] + P*transformationMatrix[4] + L*transformationMatrix[5]; In a north up image, transformationMatrix[1] is the pixel width, and transformationMatrix[5] is the pixel height. The upper left corner of the upper left pixel is at position (transformationMatrix[0],transformationMatrix[3]).

getRasterBand()

virtual IRasterBand * HydroCouple::Spatial::IRaster::getRasterBand ( int  bandIndex ) const

pure virtual

Gets the IRasterBand for the band with index bandIndex.

rasterBandCount()

virtual int HydroCouple::Spatial::IRaster::rasterBandCount ( ) const

pure virtual

Number of raster bands.

spatialReferenceSystem()

virtual ISpatialReferenceSystem * HydroCouple::Spatial::IRaster::spatialReferenceSystem ( ) const

pure virtual

The ISpatialReferenceSystem represents the spatial reference system of goemetric object.

xSize()

virtual int HydroCouple::Spatial::IRaster::xSize ( ) const

pure virtual

Number of pixels in the x direction.

ySize()

virtual int HydroCouple::Spatial::IRaster::ySize ( ) const

pure virtual

Number of pixels in y direction.
