Transform values using this normalization.

Parameters¶

valuesarray-like

The input values.

clipbool, optional

If True, values outside the [0:1] range are clipped to the [0:1] range. If None then the clip value from the ImageNormalize instance is used (the default of which is False).

invalidNone or float, optional

Value to assign NaN values generated by this class. NaNs in the input data array are not changed. For matplotlib normalization, the invalid value should map to the matplotlib colormap “under” value (i.e., any finite value < 0). If None, then the ImageNormalize instance value is used. This keyword has no effect if clip=True.
