int getBandDataType(std::size_t i) const
Returns the data type in a particular band (or dimension).
const te::rst::Band & operator[](std::size_t i) const
Access band in i position.
~Raster()
Virtual destructor.
InterpolationMethod
Allowed interpolation methods.
Definition: Enums.h:92
bool createMultiResolution(const unsigned int, const te::rst::InterpolationMethod)

te::dt::AbstractData * clone() const
It returns a clone of this object.
const te::rst::Band * getBand(std::size_t i) const
Returns the raster i-th band.
unsigned int getMultiResLevelsCount() const
Returns the current number of multi-resolution pyramid levels.
