.resize()

In Pillow, the .resize() method is used to change the size of an image. Pillow is a widely used Python library for image processing and manipulation, supporting formats such as JPEG, PNG, PPM, TIFF, GIF, and BMP It can be easily installed on a local PC using pip.

Syntax

Image.resize(size, resample=None, box=None, reducing_gap=None)

• size: A 2-tuple specifying the new size as (width, height).
• resample: Specifies the resampling filter to be used when resizing.
• box: A 4-tuple defining the region of the image to resize.
• reducing_gap: A float to optimize downscaling by resizing in multiple steps.

Note: The .resize() method requires the size parameter, while resample, box, and reducing_gap are optional parameters for additional control over the resizing process.

Example

The following example demonstrates the use of the .resize() method to change the size of the image:

from PIL import Image

# Original image is 2000x2000 pixels.
img = Image.open('pillow-resize-earth.png')

# showccasing the original image
img.show()

img_resized = img.resize((500, 500))

print(img_resized.height, img_resized.width)

# showcasing the resized image
img_resized.show()

The code snippet will display the new dimensions of the image and also showcase the image in the output as follows:

500 500
