This precise guide explains the details to resize image using Python. It covers stepwise program flow and runnable sample code to create a photo resizer using Python. Moreover, it can process JPG, GIF, BMP, PNG, and other popular image formats.

Steps to Resize Image using Python

1. Configure the application environment by installing Aspose.Imaging to resize images
2. Get the source image from the disk or a stream and load it using the Image class instance
3. Invoke the resize() method by specifying the output image dimensions and the ResizeType
4. Write the generated image in the required image format

These steps elaborate on developing an image size converter using Python. It outlines the process of loading the source image in any supported format like JPG, PNG, GIF, etc., and then specifies the resized image dimensions and the resize type. Finally, the output image can be exported to the disk or a stream depending on your application model.

Code to Create Photo Resizer using Python

This code snippet is a basic version to resize image without losing quality using Python, while it can further be improvised by changing the image scaling factor. For instance, a positive multiplying factor will make the image bigger while a negative number will result in a smaller image. Likewise, you can use different overload methods for resizing using the ImageResizeSettings class or resizing the height or width proportionally based on your requirements.
