PyToENVI

Simple Python interface to ENVI, which allows you to display images in ENVI really easily.

Usage

It's really simple to use - simply run:

from PyToENVI.ENVI import display
# Displays a file
display(filename)
  
import numpy as np
arr = np.random.rand(1000, 1000)
# Displays an array
display(arr)

This will display in the 'modern' ENVI interface. If you prefer ENVI Classic (as I do), then simply change the import to:

from PyToENVI.ENVIClassic import display

Apart from the import, all of the rest of the code will be the same regardless which version of ENVI you're using.

Installation

Installing PyToENVI is very simple - it's all pure Python, so you just need to make sure it ends up on your path somehow. Eventually, I will release a PyPI package for this, but for the moment just copy somewhere on your PYTHONPATH.

This module depends on idlpy, the IDL-Python bridge provided as part of IDL 8.5. This can't be installed automatically as a dependency, as it comes directly from Excelis (the people who make IDL). You'll need to install IDL 8.5 and then follow the instructions on their website to get it working.

Note: If you don't have IDL properly licensed then most of the functions in PyToENVI will just hang - unfortunately there doesn't seem to be a good way to get a proper exception in this situation. Therefore, make sure you're properly licensed (and connected to a VPN if you need to be), before running any PyToENVI functions.
