    output_encoding=PNG,
    quality=None,
    correct_orientation=UNCHANGED_ORIENTATION,
    rpc=None,
    transparent_substitution_rgb=None
)

Args
image_data	String of the source image data.
degrees	A value from ROTATE_DEGREE_VALUES.
output_encoding	A value from OUTPUT_ENCODING_TYPES.
quality	A value between 1 and 100 to specify the quality of the encoding. This value is only used to control JPEG quality.
correct_orientation	A value from ORIENTATION_CORRECTION_TYPE to indicate if orientation correction should be performed during the transformation.
rpc	An optional UserRPC object.
transparent_substitution_rgb	When transparent pixels are not supported in the destination image format, then transparent pixels will be substituted for the specified color, which must be in 32-bit RGB format.

Returns
