How to Create a Command-line Application with argparse.Learn how to use Python's amazing standard library to add How to do a Simple Cache with Python and functools (Video).Getting Photo Metadata (EXIF) Using Python.Check it out and see what else you can do! Related Reading Pillow can do a lot more than only extract EXIF data. The total number of lines for this GUI was only 84! You can create functional GUIs without needing to write hundreds of lines of code.

You also learned how to create a simple GUI using PySimpleGUI. Now you know how to parse out the EXIF tags from an image. If you'd like a small challenge, try adding a sg.Image() Element to this GUI so you can view the photo along with its metadata! Wrapping Up If the field isn't in the dictionary, then you display "No data" for that field. You use the dictionary's get() method to get the field. This allows you to extract the file name, absolute path, and file size using your Path object's functions and attributes. Here you load up the selected image path into Python's pathlib. When the user presses the "Load image data" button, the event is set to "load".

The last piece of the puzzle is next: while True: Once that's all done, you add the elements to your Window. PySimpleGUI makes this a snap since you can concatenate the new Elements to your elements list.

You loop over the fields dictionary you defined at the beginning of your program and add a couple of text controls that will display the Exif data you extract from your image. Here you create all the Elements you need to create your user interface. You can move on to the main() function next: def main(): If info is populated, then you loop over it and decode the Exif data and populate your exif_data dictionary before returning it. If _getexif() returns None, then you also set info to an empty dictionary. If it fails, it sets info to an empty dictionary. This function takes in the image path and attempts to extract the Exif data from it. You are now ready to learn about the get_exif_data() function: def get_exif_data(path):Įxtracts the EXIF information from the provided photo This dictionary maps the Exif name to a more readable name. Then you create a Python dictionary that holds all the Exif fields that you want to display. This is used in a file dialog that you will create later on to allow the user to select an image to load.

EDIT EXIF METADATA IN PYTHON CODE

The first half of this code is the imports you will need to make your application function. Here are the first few lines of code: # exif_viewer.py That is a good-sized chunk of code! It would be confusing to try and explain all of it at once, so to make things easier you will go over the code piece by piece. Window.update(exif_data.get(field, "No data")) If event = "Exit" or event = sg.WIN_CLOSED:Įxif_data = get_exif_data(image_path.absolute()) Window = sg.Window("Image information", elements) "Load image data", file_types=file_types, key="load", To get started, create a new file named exif_viewer.py and add this code: # exif_viewer.pyįile_types = [("(JPEG (*.jpg)", "*.jpg"),Įxtracts the Exif information from the provided photo When you get done writing your code, your Exif viewer will look like this: The first step is to find an image that has Exif data in it. Regardless of which way you end up going, you are now ready to write your GUI code! Creating a Simple Exif Viewer You can use virtualenv or Python's built-in venv module.

EDIT EXIF METADATA IN PYTHON INSTALL

You may want to install these packages in a Python virtual environment. You can install them both using pip: python -m pip install pillow PySimpleGUI Getting Startedīoth Pillow and PySimpleGUI will need to be installed to be able to follow along with this tutorial. For this tutorial, you will use PySimpleGUI. However, there are some key data points that are more useful than others.įor those pieces of data, it's nice to create a GUI so you can view it easily. You can get a lot of information about your images via the Exif data. The Pillow package gives you the ability to extract Exif (Exchangeable Image File Format) metadata from images.
