Feel free to try MSS on a system we had not tested, and let report us by creating an [issue](https://github.com/BoboTiG/python-mss/issues).
Testing
You can try the MSS module directly from the console:
python mss.py
Instance the good class
So MSS can be used as simply as:
from mss import mss screenshotter = mss()
Or import the good one:
from mss import MSSLinux as mss screenshotter = mss()
save(output, screen, callback)
For each monitor, grab a screenshot and save it to a file.
Parameters:
output - string - the output filename. It can contain '%d' which
will be replaced by the monitor number.
screen - integer - grab one screenshot of all monitors (screen=-1)
grab one screenshot by monitor (screen=0)
grab the screenshot of the monitor N (screen=N)
callback - function - in case where output already exists, call
the defined callback function with output
as parameter. If it returns True, then
continue; else ignores the monitor and
switches to ne next.
This is a generator which returns created files.
Examples
One screenshot per monitor:
for filename in screenshotter.save():
print(filename)
Screenshot of the monitor 1:
for filename in screenshotter.save(screen=1):
print(filename)
Screenshot of the monitor 1, with callback:
def on_exists(fname):
''' Callback example when we try to overwrite an existing
screenshot.
'''
from os import rename
from os.path import isfile
if isfile(fname):
newfile = fname + '.old'
print('{0} -> {1}'.format(fname, newfile))
rename(fname, newfile)
return True
for filename in screenshotter.save(screen=1, callback=on_exists):
print(filename)
A screenshot to grab them all:
for filename in screenshotter.save(output='fullscreen-shot.png', screen=-1):
print(filename)
