__call__(values, clip=True, out=None)[source] [edit on github]

Transform values using this interval.

Parameters:
values : array-like

The input values.

clip : bool, optional

If True (default), values outside the [0:1] range are clipped to the [0:1] range.

out : ndarray, optional

If specified, the output values will be placed in this array (typically used for in-place calculations).
Returns:
result : ndarray

The transformed values.
get_limits(values)[source] [edit on github]

Return the minimum and maximum value in the interval based on the values provided.

Parameters:
values : ndarray

The image values.
Returns:
vmin, vmax : float

The mininium and maximum image value in the interval.
