image_ratio = image.width / image.height

screen_ratio = display.width / display.height

if screen_ratio < image_ratio:

scaled_width = image.width * display.height // image.height

scaled_height = display.height

else:

scaled_width = display.width

scaled_height = image.height * display.width // image.width

image = image.resize((scaled_width, scaled_height), Image.BICUBIC)

Next we want to figure the starting x and y points of the image where we want to begin cropping it so that it ends up

centered. We do that by using a standard centering function, which is basically requesting the difference of the center

of the display and the center of the image. Just like with scaling, we replace the image variable with the newly

cropped image.

x = scaled_width // 2 - display.width // 2

y = scaled_height // 2 - display.height // 2

image = image.crop((x, y, x + display.width, y + display.height))

Finally, we take our image , draw it to the frame buffer and display it. At this point, the image should have the exact

same dimensions at the display and fill it completely.

display.image(image)

display.display()

Now go to the command prompt on your Raspberry Pi and run the script with the following command:

python3 epd_pillow_image.py

After a few seconds, your display should show this image:
