Method Details | [hide private]

### __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, win_xsize=None, win_ysize=None, buf_xsize=None, buf_ysize=None, buf_type=None, buf_obj=None, resample_alg=gdalconst.GRIORA_NearestNeighbour, callback=None, callback_data=None) | 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, cache_size=10*1024*1024, page_size_hint=0, options=None) | source code
Return a NumPy array for the band, seen as a virtual memory mapping. 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.

### GetVirtualMemAutoArray(self, eAccess=gdalconst.GF_Read, options=None) | source code
Return a NumPy array for the band, seen as a virtual memory mapping. 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, cache_size=10*1024*1024, options=None) | source code
Return a NumPy array for the band, seen as a virtual memory mapping with a tile organization. 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.
