These few lines of Python code will resize an image (fullsizedimage.jpg) using PIL to a width of 300 pixels, which is set in the variable basewidth and a height proportional to the new width. The proportional height is calculated by determining what percentage 300 pixels is of the original width (img.size0) and then multiplying the original.
- With scikit-image, a Python image processing library with a versatile set of optimization and transformation routines, e.g., rescale and resize. A Superb Alternative for Optimization. With Cloudinary, you can efficiently optimize media assets—regardless of programming language. One reason is that, by default, Cloudinary automatically performs.
- It also helps in zooming in images. Many times we need to resize the image i.e. Either shirk it or scale up to meet the size requirements. OpenCV provides us several interpolation methods for resizing an image. Choice of Interpolation Method for Resizing – cv2.INTERAREA: This is used when we need need to shrink an image.
- One of the most popular and considered as default library of python for image processing is Pillow. Pillow is an updated version of the Python Image Library or PIL and supports a range of simple and advanced image manipulation functionality. It is also the basis for simple image support in other Python libraries such as sciPy and Matplotlib.

To resize an image with Python Pillow, you can use resize() method of PIL.Image.Image Class. You can pass parameters like resulting image size, pixel resampling filter and the box region of source to be considered.
In this tutorial, we shall learn how to resize an image using PIL, with example Python programs.
Syntax – PIL Image.resize()
The syntax of resize() method is as shown in the following code snippet.
where
- size is to passed as tuple (width, height). This is the size requested for the resulting output image after resize.
- resample is the filter that has to be used for resampling. It is optional. You can pass:
- PIL.Image.NEAREST
- PIL.Image.BOX
- PIL.Image.BILINEAR
- PIL.Image.HAMMING
- PIL.Image.BICUBIC
- PIL.Image.LANCZOS
- box is an optional 4-tuple of floats giving the region of the source image which should be considered as input for resize. The values should be within (0, 0, width, height) rectangle. If omitted or None, the entire source is used.
With proper values provided to size parameter, you can either downsize or enlarge the input image.
Example 1: Resize an image with default values
In the following example, we will read an image and resize it to (200, 200).

Input image: sample-image.png
Output Image – resize-output.png
Resize Image Python Pil
The whole source image is considered for resize, as we have not provided any value for box parameter. In the next example, we will provide the box parameter and find the output image.

Example 2: Resize Image with only box of the input image
In the following example, we will provide the box parameter. By this we consider only the box area of the input image and then resize it to size.

If you observe, only the box part of input image is considered for the resize action. Rightfont 5 5 5 download free.
