I would like to make a program that screens the screen (screen shot) in Python.
I found the following code:
import pyscreenshot as ImageGrab
if __name__ == "__main__":
# fullscreen
im=ImageGrab.grab()
im.show()
The code does nothing (apparently crashes)!
What does it mean: if __name__ == "__main__": ?
Using Linux BackBox
Firstly if you have not installed the module, install :
~$ sudo apt-get install python-pip && pip install pyscreenshot
Obs : pip is a tool for installing modules of Python.
To use pyscreenshot just do:
import pyscreenshot as ImageGrab
def main():
imagem = ImageGrab.grab()
imagem.save('screenShot1.jpg', 'jpeg')
if __name__ == "__main__":
main()
The code above will generate a JPEG image and save it as screenShot1.jpg in the same script directory.
Your second question is answered here .
