What is more friendly to beginners is that most of the class libraries required for PHP website development are already available online. What I bring to you this time is a PHP class library for processing thumbnails. Friends who need it can use it directly.

The requirement for web images is to publish images of the highest possible quality in the shortest possible transmission time. Therefore, when designing and processing web page images, it is required that the images have the highest possible resolution and the smallest possible size, so that the download speed of the images can be the fastest. To do this, the image must be optimized.

Also called image processing. Image processing generally refers to digital image processing. A digital image refers to a large two-dimensional array captured by industrial cameras, video cameras, scanners and other equipment. The elements of the array are called pixels, and their values ​​are called grayscale values. Image processing technology generally includes three parts: image compression, enhancement and restoration, matching, description and recognition.

It consists of three parts: software related to embedded text management, managed embedded text, and data structures required to implement embedded text management. Embedded text is the core of the embedded text system. It is the storage form of user data information, thereby realizing the functions of the embedded system.
