python screenshot

Project Description

The pyscreenshot module can be used to copy the contents of the screen to a PIL or Pillow image memory. Replacement for the ImageGrab Module, which works on Windows only. For handling image memory (e.g. saving to file, converting,..) please read PIL or Pillow documentation.

Goal:
Pyscreenshot tries to allow to take screenshots without installing 3rd party libraries. It is cross-platform but useful for Linux based distributions. It is only a pure Python wrapper, a thin layer over existing back-ends. Its strategy should work on most Linux distributions: a lot of back-ends are wrapped, if at least one exists then it works, if not then one back-end should be installed. Performance and interactivity are not important for this library.

Examples

grab and show the whole screen:

#-- include('examples/showgrabfullscreen.py') --#
import pyscreenshot as ImageGrab

if __name__ == "__main__":
    # fullscreen
    im=ImageGrab.grab()
    im.show()
#-#

to start the example:

python -m pyscreenshot.examples.showgrabfullscreen

grab and show the part of the screen

#-- include('examples/showgrabbox.py')--#
import pyscreenshot as ImageGrab

if __name__ == "__main__":
    # part of the screen
    im=ImageGrab.grab(bbox=(10,10,510,510)) # X1,Y1,X2,Y2
    im.show()
#-#

to start the example:

python -m pyscreenshot.examples.showgrabbox

Installation

General

  • install pip

  • install PIL or Pillow

  • install at least one back-end

Back-end performance:

The performance can be checked with pyscreenshot.check.speedtest.

Example:

#-- sh('python -m pyscreenshot.check.speedtest --virtual-display 2>/dev/null') --#
