Fedora 26 OSError: cannot identify image file #45

Closed definite-purple closed 6 years ago

definite-purple commented 7 years ago

everytime I try to use pyscreenshot.grab() with any argument, I receive an OSError. This is using the example-code:

-- include('examples/showgrabfullscreen.py') --

    import pyscreenshot as ImageGrab

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

OSError Traceback (most recent call last)

I realised Python 3.6 isn't even supported yet.

Well, this occurs with Python 3.5 too anyway, using Windows 10 Bash Terminal.
