Note that the approach in createLookupArray() is limited to whole-number input values, as the input value is used as an index into an array. The applyLookupArray() function works by using a source array's values as indices into the lookup array. Python's slice notation ([:]) is used to copy the looked-up values into a destination array.
Let's consider another optimization. What if we always want to apply two or more curves in succession? Performing multiple lookups is inefficient and may cause loss of precision. We can avoid this problem by combining two curve functions into one function before creating a lookup array. Let's edit utils.py again and add the following function that returns a composite of two given functions:
def createCompositeFunc(func0, func1): """Return a composite of two functions.""" if func0 is None: return func1 if func1 is None: return func0 return lambda x: func0(func1(x))
