__init__(self, *args, **kwargs)
(Constructor)

source code 
Overrides: MajorObject.__init__

__repr__(self)
(Representation operator)

source code 
Overrides: _swig_repr

ReadAsArray(self, xoff=0, yoff=0, xsize=None, ysize=None, buf_obj=None, buf_xsize=None, buf_ysize=None, buf_type=None, resample_alg=gdalconst.GRIORA_NearestNeighbour, callback=None, callback_data=None, interleave='band')

source code 

Reading a chunk of a GDAL band into a numpy array. The optional (buf_xsize,buf_ysize,buf_type) parameters should generally not be specified if buf_obj is specified. The array is returned

GetVirtualMemArray(self, eAccess=gdalconst.GF_Read, xoff=0, yoff=0, xsize=None, ysize=None, bufxsize=None, bufysize=None, datatype=None, band_list=None, band_sequential=True, cache_size=10*1024*1024, page_size_hint=0, options=None)

source code 

Return a NumPy array for the dataset, seen as a virtual memory mapping. If there are several bands and band_sequential = True, an element is accessed with array[band][y][x]. If there are several bands and band_sequential = False, an element is accessed with array[y][x][band]. If there is only one band, an element is accessed with array[y][x]. Any reference to the array must be dropped before the last reference to the related dataset is also dropped.

GetTiledVirtualMemArray(self, eAccess=gdalconst.GF_Read, xoff=0, yoff=0, xsize=None, ysize=None, tilexsize=256, tileysize=256, datatype=None, band_list=None, tile_organization=gdalconst.GTO_BSQ, cache_size=10*1024*1024, options=None)

source code 

Return a NumPy array for the dataset, seen as a virtual memory mapping with a tile organization. If there are several bands and tile_organization = gdal.GTO_TIP, an element is accessed with array[tiley][tilex][y][x][band]. If there are several bands and tile_organization = gdal.GTO_BIT, an element is accessed with array[tiley][tilex][band][y][x]. If there are several bands and tile_organization = gdal.GTO_BSQ, an element is accessed with array[band][tiley][tilex][y][x]. If there is only one band, an element is accessed with array[tiley][tilex][y][x]. Any reference to the array must be dropped before the last reference to the related dataset is also dropped.
