Features:
- python wrapper
- supported python versions: 2.6, 2.7, 3.3, 3.4, 3.5
- back-ends: Xvfb_, Xephyr_, Xvnc_
.. warning:: at least one back-end should be installed
Known problems:
- only a few back-end options are supported
Possible applications:
* GUI testing
* automatic GUI screenshot
Basic usages
============
Start Xephyr::
from pyvirtualdisplay import Display
xephyr=Display(visible=1, size=(320, 240)).start()
Create screenshot of xmessage with Xvfb::
from easyprocess import EasyProcess
from pyvirtualdisplay.smartdisplay import SmartDisplay
with SmartDisplay(visible=0, bgcolor='black') as disp:
with EasyProcess('xmessage hello'):
img = disp.waitgrab()
img.show()
Installation
============
General
-------
* install Xvfb_ or Xephyr_ or Xvnc_.
* install pip_
* optional: pyscreenshot_ and PIL_ should be installed for ``smartdisplay`` submodule
* install the program::
# as root
pip install pyvirtualdisplay
Ubuntu 14.04
------------
::
sudo apt-get install python-pip
sudo apt-get install xvfb xserver-xephyr vnc4server
sudo pip install pyvirtualdisplay
# optional
sudo apt-get install python-pil scrot
sudo pip install pyscreenshot
# optional for examples
sudo pip install entrypoint2
Uninstall
---------
::
# as root
pip uninstall pyvirtualdisplay
Usage
=====
.. #-- from docs.screenshot import screenshot--#
.. #-#
GUI Test
--------
Testing ``gnumeric`` on low resolution::
#-- include('examples/lowres.py') --#
from easyprocess import EasyProcess
from pyvirtualdisplay import Display
if __name__ == "__main__":
Display(visible=1, size=(320, 240)).start()
EasyProcess('gnumeric').start()
#-#
Image:
.. #-- screenshot('python -m pyvirtualdisplay.examples.lowres','lowres.png') --#
.. image:: _img/lowres.png
.. #-#
Screenshot
----------
Create screenshot of ``xmessage`` in background::
#-- include('examples/screenshot3.py') --#
'''
using :keyword:`with` statement
'''
from easyprocess import EasyProcess
from pyvirtualdisplay.smartdisplay import SmartDisplay
if __name__ == "__main__":
with SmartDisplay(visible=0, bgcolor='black') as disp:
with EasyProcess('xmessage hello'):
img = disp.waitgrab()
img.show()
#-#
Image:
.. #-- screenshot('python -m pyvirtualdisplay.examples.screenshot3','screenshot3.png') --#
.. image:: _img/screenshot3.png
.. #-#
vncserver
---------
::
#-- include('examples/vncserver.py') --#
'''
Example for Xvnc backend
'''
from easyprocess import EasyProcess
from pyvirtualdisplay.display import Display
if __name__ == "__main__":
with Display(backend='xvnc', rfbport=5904) as disp:
with EasyProcess('xmessage hello') as proc:
proc.wait()
#-#
xauth
=====
Some programs require a functional Xauthority file. PyVirtualDisplay can
generate one and set the appropriate environment variables if you pass
``use_xauth=True`` to the ``Display`` constructor. Note however that this
feature needs ``xauth`` installed, otherwise a
``pyvirtualdisplay.xauth.NotFoundError`` is raised.
