automatical_capture

take a screenshot using shortcut key

Process

• Configuration

  • Need to enable the terminal in "easy of use"
    
    

  • ready for the screen to be captured.

• Windows OS

  • screenshot
    • Click top-left and bottom-right -> specify capture area
    • PIL: Image.Grab()
    • RGB color convert
    • resizing & upscaling
    • PIL object to save a list

• Mac OS

  • screenshot
    • Change the folder where the screenshot will be saved
    • Change the screenshot saving format
    • Screenshot preview option turn off
    • cmd + shift + 5: use shortcut key
      • Press shift + command + 5, and frame the part of the PDF that needs to be captured
    • Open a saved screenshot
    • PIL object to save a list

• Common

  • Find duplicate images

    1. Image object to pixel(numpy array) for compare
    2. If step one true -> Get image file byte size for compare
    3. If step two true -> remove image file, limit count increment
    4. If limit == user-set limit number -> End all captures, convert captured images to PDFs

  • Convert PDF

    1. PIL(RGB) object saving array[0] append array[1:]

• Teardown only MacOS

  • Reset options
    • Change the changed filename, screenshot save location default
    • Delete all files in the screenshots folder
      • if you don't want to delete, you can try add system argument -r 0

Modify hotkeys

• Go to mac OS python file

  def select_frame_size(self):
      self.press_keys(
          [
              self.keyboard_key.shift,
              self.keyboard_key.cmd_l,
              pynput.keyboard.KeyCode.from_char("5"),
          ]
      )
  
  def take_a_screenshot(self):
      self.press_keys([self.keyboard_key.enter])
  
  def next_page(self):
      self.press_keys([self.keyboard_key.right])

  • Go to keyboard module

    def keyboard_controll(self):
    
          time.sleep(0.2)
          self.select_frame_size()
          time.sleep(0.2)
          self.take_a_screenshot()
          time.sleep(0.2)
          self.next_page()

• Go to windows OS python file

  def select_frame_size(self):
      self.mouse_controller.drag_listen()
      time.sleep(0.2)
  
  def take_a_screenshot(self) -> PIL:
      _img = ImageGrab.grab(self.mouse_controller.bounding_box_position)  # screen capture -> PIL Object
      new_size = (_img.width*2, _img.height*2)
      better_quality_image = _img.resize(new_size, Image.LANCZOS)
      return better_quality_image
  
  def next_page(self):
      self.press_keys([self.keyboard_key.right])
  
  def keyboard_controll(self) -> PIL:  # override
      
      time.sleep(0.2)
      _img = self.take_a_screenshot()
      time.sleep(0.2)
      self.next_page()
  
      return _img

Quick Start

• git clone

• install library

  pip3 install -r requirments.txt
  

• run

  • system arguments help command

    optional arguments:
    -h, --help            show this help message and exit
    -t TIME, --time TIME  Run process after wait time >> default = 1
    -r {0,1}, --remove {0,1}
                            Is saved screenshot files remove all >> 0: keep 1: delete | default = 1
    
    -c {0,1}, --convert {0,1}
                            Is screenshot images to PDF >> 0: False 1: True | default = 1
