Returns:

the value of a cell in the original image coords.

getDataType

public int getDataType()

Description copied from interface: ISextanteRasterLayer

Returns the data type of the layer

Returns:

the data type of the layer

getLayerCellSize

public Point2D.Double getLayerCellSize()

Description copied from interface: ISextanteRasterLayer

Return the original cellsize of the layer. X and Y cellsizes are assumed to be equal

Returns:

the original cellsize of the layer

getLayerGridExtent

public GridExtent getLayerGridExtent()

Returns:

An object with information about the CRS used for this layer (i.e. a string with a EPSG code)

getFullExtent

public Rectangle2D getFullExtent()

Returns the extent covered by the layer

Returns:

open

public void open()

Description copied from interface: ISextanteDataObject
