Module iaf.io.cast

Data type casting utilities.

Functions

def safe_to_uint16(img: numpy.ndarray) ‑> numpy.ndarray

Casts the input array to np.uint16 making sure to avoid overflows. No rescaling is applied.

Parameters

img : N-D array

Two-dimensional, three-dimensional, or RGB(A) image of type bool, np.uint8, np.float32, np.float64 to convert to np.uint16.

Returns

out : N-D array

Same dimensionality of the input, but of type np.uint16.

def safe_to_uint8(img: numpy.ndarray) ‑> numpy.ndarray

Casts the input array to np.uint8 making sure to avoid overflows. No rescaling is applied.

Parameters

img : N-D array

Two-dimensional, three-dimensional, or RGB(A) image of type bool, np.uint16, np.float32, np.float64 to convert to np.uint8.

Returns

out : N-D array

Same dimensionality of the input, but of type np.uint8.
