Pure python implementation of reading a chunk of a GDAL file into a numpy array. Used by the gdal.Band.ReadAsArray method.

osgeo.gdal_array.BandWriteArray(band, array, xoff=0, yoff=0, resample_alg=0, callback=None, callback_data=None)

Pure python implementation of writing a chunk of a GDAL file from a numpy array. Used by the gdal.Band.WriteArray method.

osgeo.gdal_array.CopyDatasetInfo(src, dst, xoff=0, yoff=0)

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.
