Saving image which is displayed using peek() in python - 


  import matplotlib.pyplot plt   import sunpy.spectra   import sunpy.data.sample   sunpy.spectra.sources.callisto import callistospectrogram   image = callistospectrogram.read(sunpy.data.sample.callisto_image)   image.peek()

then how save image using command?

i don't have sunpy environment test on, can give following shot?

import matplotlib matplotlib.use('agg') import matplotlib.pyplot plt import sunpy.spectra import sunpy.data.sample sunpy.spectra.sources.callisto import callistospectrogram image = callistospectrogram.read(sunpy.data.sample.callisto_image) image.plot() plt.savefig('myfig')

based on generate images without having window appear:

the easiest way use non-interactive backend (see backend?) such agg (for pngs), pdf, svg or ps. in figure-generating script, call matplotlib.use() directive before importing pylab or pyplot:

import matplotlib matplotlib.use('agg') import matplotlib.pyplot plt plt.plot([1,2,3]) plt.savefig('myfig')

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now
