Manipulating Images with the Python Imaging Library
Article Introduction：Python Image Processing Library PIL/Pillow Getting Started Guide
Core points
Python Image Processing Library (PIL) is a free tool that adds image processing functions to the Python interpreter, supports various image file formats, and provides standard image processing programs such as pixel-based operations, filters, image enhancement, etc. wait.
Although the last version of PIL (1.1.7) was released in 2009 and only supports Python 1.5.2-2.7, the project named Pillow has fork the PIL code base and added support for Python 3.x to make It has become a viable option for most Python users.

Wrap and Render Multiline Text on Images Using Python&#s Pillow Library
Article Introduction：Python image processing: Pillow library implements automatic line-wrapping text annotation. With its rich open source libraries, Python has become a leading programming language in the field of image processing. Pillow is one of the commonly used image processing libraries. It is simple, easy to use and has complete documentation. It is often used for operations such as image scaling, cropping, brightness adjustment and annotation. However, Pillow has a problem with text annotation: when the text exceeds the width of the text box, it will not wrap automatically. The Pillow library itself does not provide this function, and we need to write the logic implementation ourselves. This tutorial will demonstrate how to use the Pillow library to add a word-wrap text box in Python to achieve correct image text annotation. The final effect is as follows: The picture above is

Imagick vs GD
Article Introduction：Key Points
GD and ImageMagick are both popular PHP image processing libraries. GD is more widely used and ImageMagick is more powerful.
In terms of performance, there is no absolute advantage or disadvantage between the two, and the speed depends on the specific application scenario.
The encoding styles are significant. GD adopts procedural programming, and ImageMagick supports object-oriented programming through the Imagick class.
In addition to these two libraries, there are other options, such as cloud image processing platforms or components that have been integrated into the application.
introduction
In PHP applications, if you need to create thumbnails, apply image filters, or perform other image conversions, you need to use the image processing library. Usually, you'll choose GD or ImageMagick. But which library

php function to resize an image
Article Introduction：The most direct way to resize images using PHP is to use the GD library. 1. Load the original image; 2. Create a new canvas of the specified size; 3. Copy and resample the original image onto the new canvas. If the aspect ratio needs to be maintained, the target size is dynamically adjusted by calculating the aspect ratio. After the adjustment is completed, you can choose to output the image to the browser or save it to a file and use imagedestroy() to free up memory. When processing PNG images, transparent channel support is required. Make sure the GD library is enabled and verify the file type and size before processing uploaded images.

How to perform basic image processing operations in Python with Pillow?
Article Introduction：Pillow is a powerful and easy-to-use Python image processing library. 1. First install and import the library through pipinstallpillow; 2. Use Image.open() to open the image, save() to save the image, and the format is automatically recognized by the file extension; 3. resize() can adjust the image size but not maintain the aspect ratio, thumbnail() creates thumbnail while maintaining the aspect ratio; 4.crop() accepts (left, upper, right, lower) tuple for cropping; 5.rotate() rotates the image counterclockwise at the angle, expand=True can retain the complete image, and transpose() can realize water
