raster bands values are instantiated as an array of zeros and the "no
data" value is set to ``None``.
.. object:: papsz_options
.. versionadded:: 2.0
A dictionary with raster creation options. The key-value pairs of the
input dictionary are passed to the driver on creation of the raster.
The available options are driver-specific and are described in the
documentation of each driver.
The values in the dictionary are not case-sensitive and are automatically
converted to the correct string format upon creation.
The following example uses some of the options available for the
`GTiff driver`__. The result is a compressed signed byte raster with an
internal tiling scheme. The internal tiles have a block size of 23 by 23::
