* ReadMe for ColorPy 0.1.0. *

ColorPy is a Python package that can convert physical descriptions of light -
spectra of light intensity vs. wavelength - into RGB colors that can be drawn on a computer screen. It provides a nice set of attractive plots that you can make of such spectra, and some other color related functions as well.

Unpacking the Distribution:

The instruction depend on if you are using Windows or Linux. If you are using Windows, you can use the binary distribution executable, and all you need to do is run that. Otherwise...

Windows -

Unzip the .zip distribution. Recent versions of Windows (XP or later), will unpack the directory automatically, you can simply enter the directory in Windows Explorer. You will probably need to copy the uncompressed files into another directory.

Linux -

The distribution is a compressed tar archive, uncompress it as follows:

gunzip -c colorpy-0.1.0.tar.gz | tar xf - cd colorpy-0.1.0


To install ColorPy from the source distributions (.zip on Windows, or .tar.gz on Linux) you must first unpack the distribution.

Then, from the directory in which the files are unpacked, run:

python install

It is possible that you may need to supply a path to the Python executable. You also probably will need administrator privileges to do this.

This should complete the installation.

If you are installing from the Windows binary distribution (.win32.exe), then all you need to do is run that executable and follow the prompts.

After installation, I recommend that you run the test cases. In the Python interpreter, do:

import colorpy.test colorpy.test.test()

This should run several test cases. As an additional (and more interesting) test, create the sample figures:

import colorpy.figures colorpy.figures.figures()

This should create a number of plot files (typically .png files) in the current directory. These will include all of the plots in the HTML documentation, as well as several others.
