def __init__(self, data = None, header = None, name = None, do_not_scale_image_data = False, uint = True, scale_back = None, ver = None)

Construct an image HDU.

data : array: The data in the HDU.
header : `~astropy.io.fits.Header`: The header to be used (as a template). If header is None, a minimal header will be provided.
name : str, optional: The name of the HDU, will be the value of the keyword EXTNAME.
do_not_scale_image_data : bool, optional: If True, image data is not scaled using BSCALE/BZERO values when read. (default: False)
uint : bool, optional: Interpret signed integer data where BZERO is the central value and BSCALE == 1 as unsigned integer data. For example, int16 data with BZERO = 32768 and BSCALE = 1 would be treated as uint16 data. (default: True)
scale_back : bool, optional: If True, when saving changes to a file that contained scaled image data, restore the data to the original type and reapply the original BSCALE/BZERO values. This could lead to loss of accuracy if scaling back to integer values after performing floating point operations on the data. Pseudo-unsigned integers are automatically rescaled unless scale_back is explicitly set to False. (default: None)
ver : int > 0 or None, optional: The ver of the HDU, will be the value of the keyword EXTVER. If not given or None, it defaults to the value of the EXTVER card of the header or 1. (default: None)
