Clamping (graphics)

In computer science, clamping, or clipping is the process of limiting a value to a range between a minimum and a maximum value. Unlike wrapping, clamping merely moves the point to the nearest available value.

In Python, clamping can be defined as follows:

def clamp(x, minimum, maximum):
    if x < minimum:
        return minimum
    if x > maximum:
        return maximum
    return x

This is equivalent to max(minimum, min(x, maximum)) for languages that support the functions min and max.
