REQUIREMENTS:
posix os
Python 2.6
Python Imaging Library http://www.pythonware.com/products/pil
numpy http://www.scipy.org/Download

INSTALL:
python setup.py build
python setup.py install
python setup.py dev --quicktest

USAGE:
$ python setup.py dev --quicktest
render color image in shell terminal &
plot scientific functions as well



>>> from asciiporn import *

>>> print( img2txt("filename") )
display color image from gif, jpg, bmp, ... to screen.
only works if u have Python Imaging Library installed

>>> help(img2txt.load)
display img2txt options



>>> plot(ft = lambda t: cos(t), tmin = 0, tmax = 16)
plot cos(t) for t = [0, 16]

>>> plot(ft = [cos, sin], tmin = 0, tmax = 16)
plot 2 functions, cos & sin

>>> plot( y = [1.5, 2.5, 3.5], t = [0, 1, 2] )
plot datapoints (y, t) = (1.5, 0), (2.5, 1), (3.5, 2)

>>> f = lambda t, z: sin( t*(2*pi + z) ) * (0.5 + z) - z
>>> plot3d(ftz = ftz, tmin = 0, tmax = 16, zmin = 0, zmax = 1)
plot f in 3d using specified ranges for t & z

>>> help(plot.__call__)
>>> help(dataZYT.__new__)
display plot options



>>> fitpoly2d.test()
test asciiporn's polynomial fitting routine
peruse fitpoly.test in asciiporn/main.py for usage

>>> fft2d.test()
test asciiporn's cosine fitting routine
peruse fft2d.test in asciiporn/main.py for usage
