The pyscreenshot module can be used to copy the contents of the screen to a PIL image memory or file. Replacement for the ImageGrab Module, which works on Windows only.

• documentation: http://ponty.github.com/pyscreenshot

Features:

• Cross-platform wrapper
• Capturing the whole desktop
• Capturing an area
• saving to file or PIL image memory
• some back-ends are based on this discussion: http://stackoverflow.com/questions/69645/take-a-screenshot-via-a-python-script-linux
• pure Python library

• Plugin based, it has wrappers for various back-ends:

  • scrot
  • ImageMagick
  • PyGTK
  • PIL (only on windows)
  • PyQt4
  • wxPython

Known problems:

• not implemented: Capturing an active window
• different back-ends generate slightly different images from the same desktop, this should be investigated
• ImageMagick creates blackbox on some systems
• PyGTK back-end does not check $DISPLAY -> not working with Xvfb
• slow: 0.2s - 0.7s

ImageGrab.grab_to_file('im.png')
