nmap's Introduction

nmap

Map a number from one range to another

>>> from nmap import nmap
>>> mapfn = nmap(0, 100, 500, 1000)
>>> mapfn(0)
500.0
>>> mapfn(50)
750.0
>>> mapfn(100)
1000.0

Example using the normfn argument to cast output to int

>>> from nmap import nmap
>>> mapfn = nmap(500, 1000, 1, 10, normfn=int)
>>> mapfn(500)
1
>>> mapfn(750)
5
>>> mapfn(1000)
10

Example using easing functions as curvefn

import matplotlib.pyplot as plt
import numpy as np
import math

from ease import *
from nmap import nmap

x = np.linspace(0, 1)
yaxis = (np.linspace(0, 0), np.linspace(-10, 10))
easefns = [cubic_in, cubic_out, cubic_in_out, out_back]
fns = [nmap(0, 1, 500, 1500, fn) for fn in easefns]
size = math.ceil(math.sqrt(len(fns)))
size = size * 100 + size * 10

for i, fn in enumerate(fns):
    plt.subplot(size + i + 1)
    plt.plot(*yaxis, 'black')
    plt.plot(*reversed(yaxis), 'black')
    plt.plot(x, np.array([fn(xn) for xn in x]))
    plt.axis([0, 1, 500, 1720])

plt.show()

nmap's Issues

Rename this module

I strongly suggest that you rename your module for the following reasons:

there is a well-known tool out there called nmap. your choice looks very much that you want to piggyback on their name and search engine results
your module will never make it into the repositories of the distributions because py-nmap or python-nmap is already taken by the binding of the tool mentioned above
