The output dataset has the same number of bands, size, data type, projection
and geotransform as the input dataset. It is therefore appropriate to create the output
dataset with the
CreateCopy
method of the driver. Before using a particular driver,
all drivers must be registered (
GDALAllRegister()
). The input dataset will not
be altered and is opened in read only mode.
