If Pillow is not installed, you can install it with: python3 -m pip install pillow How to Manipulate Images with PIL and ImageTk To check if Pillow is already installed, enter the following command in a Python console: help('PIL') If a size is not specified, the Label will be just large enough to display its contents.
Width and height options that can be used to set the Label size for an image.Basic image processing and manipulation functionality.Support for a wide range of image file formats, including PNG, JPEG and GIF.Pillow has the following characteristics: Pillow is a fork of the Python Imaging Library, and can be imported in a Python console as PIL. Tkinter relies on Pillow for working with images. For example, a label can be placed in a frame using the place layout manager at x,y coordinates, as shown in the following example: ace(x=160, y=60) How to Use Pillow with Tkinter Tkinter has three built-in Layout Managers that can be used to position labels containing images in a frame: pack, grid, and place. The BitmapImage class is used to display only monochrome (two-color) images in labels.For information on how you can work with more image formats, see the Pillow section below. Note that only GIF and PGM/PPM image formats are supported. The PhotoImage class is used to display grayscale or true color icons, as well as images in labels.To display an image requires the use of Image and ImageTk imported from the Python Pillow (aka PIL) package.Ī label widget can display either PhotoImage or BitmapImage objects: Tkinter’s label widget can be used to display either images or text.
How to Display Images with Tkinter’s Label Widget The reason for this is because images in applications can vary from background wallpaper, to positioned images that represent processes in underlying code, to clickable images or icons that perform an action when clicked. Note that depending on the purpose of an image in a Tkinter application, different coding may be required. Using Pillow, a Tkinter function that displays a text-based message can instead display an image-based message. Running the above code will display a resized image in the window.Tkinter relies on the Python Pillow (aka PIL) package for image processing capabilities. # Resize the image in the given (width, height) # Create an instance of tkinter frame or window Let us have a look at the example where we will open an image and resize it to display in the window through the label widget. The resized image can later be processed and displayed through the label widget. To resize the image, we can use image_resize((width, height) **options) method. We can use Pillow to open the images, resize them and display in the window. The PIL or Pillow library in Python is used for processing images in a Tkinter application.
