### DatasetReadAsArray(ds, xoff=0, yoff=0, win_xsize=None, win_ysize=None, buf_obj=None, buf_xsize=None, buf_ysize=None, buf_type=None, resample_alg=gdal.GRIORA_NearestNeighbour, callback=None, callback_data=None, interleave='band', band_list=None) | source code
Pure python implementation of reading a chunk of a GDAL file into a numpy array. Used by the gdal.Dataset.ReadAsArray method.

### DatasetWriteArray(ds, array, xoff=0, yoff=0, band_list=None, interleave='band', resample_alg=gdal.GRIORA_NearestNeighbour, callback=None, callback_data=None) | source code
Pure python implementation of writing a chunk of a GDAL file from a numpy array. Used by the gdal.Dataset.WriteArray method.

### BandReadAsArray(band, xoff=0, yoff=0, win_xsize=None, win_ysize=None, buf_xsize=None, buf_ysize=None, buf_type=None, buf_obj=None, resample_alg=gdal.GRIORA_NearestNeighbour, callback=None, callback_data=None) | source code
Pure python implementation of reading a chunk of a GDAL file into a numpy array. Used by the gdal.Band.ReadAsArray method.

### BandWriteArray(band, array, xoff=0, yoff=0, resample_alg=gdal.GRIORA_NearestNeighbour, callback=None, callback_data=None) | source code
Pure python implementation of writing a chunk of a GDAL file from a numpy array. Used by the gdal.Band.WriteArray method.

### RATWriteArray(rat, array, field, start=0) | source code
Pure Python implementation of writing a chunk of the RAT from a numpy array. Type of array is coerced to one of the types (int, double, string) supported. Called from RasterAttributeTable.WriteArray

### RATReadArray(rat, field, start=0, length=None) | source code
Pure Python implementation of reading a chunk of the RAT into a numpy array. Called from RasterAttributeTable.ReadAsArray

### CopyDatasetInfo(src, dst, xoff=0, yoff=0) | source code
    Copy georeferencing information and metadata from one dataset to another.
    src: input dataset
    dst: output dataset - It can be a ROI -
    xoff, yoff:  dst's offset with respect to src in pixel/line.

    Notes: Destination dataset must have update access.  Certain formats
           do not support creation of geotransforms and/or gcps.
