python wrapper around SAO XPA and DS9

Project description


This project is aimed to provide a python interface for some programs
developed by Smithsonian Astrophysical Observatory(SAO). One of the
main goal is to communicate with ds9 from python shell via the XPA
protocol. It provides a python wrapper for subset of XPA library and
python module for ds9 based on the XPA module.

pyregion is "easy_install"able.

pip install pysao


>>> import pysao

# run new instance of ds9
>>> ds9 = pysao.ds9()

>>> import numpy
>>> im = numpy.reshape(numpy.arange(100), (10, 10))
# display 2-d array
>>> ds9.view(im)

>>> import pyfits
>>> f ='test.fits')
# display first extension of fits file
>>> ds9.view(f[0])

# access with XPA method.
>>> ds9.set('file test.fits')
>>> ds9.get('file')

# list available xpa commands
>>> ds9.xpa_help()

# help on the specific xpa command
>>> ds9.xpa_help("tile")
