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

Article Introduction：TypedArrays is a tool in JavaScript for processing binary data and high-performance computing. They provide the advantages of performance optimization, memory efficiency, and direct manipulation of binary data, but need to be aware of the issues of type conversion and missing methods. In practical applications, TypedArrays are often used for image processing, such as creating RGBA images. When using it, you should pay attention to batch operations, direct operation of ArrayBuffer, and avoid frequent creation and destruction to optimize performance.

Article Introduction：Feather value controls the width of the gradient area at the edge of the image. The smaller the value, the sharper the edge, the larger the value, and the softer the edge. In practical applications, smaller feather values ??are suitable for situations where clear edges are needed, while larger feather values ??are suitable for situations where soft transitions are needed. Adjusting feather values ??requires trade-offs based on actual goals and image processing principles.

Article Introduction：PyPDF2 is a practical library in Python for processing PDF files. It supports extraction of text, merging and splitting PDFs, adding watermarks and encryption operations. 1. When extracting text, you can read the page through the PdfReader class and call the extract_text() method, but the scanned file needs to be combined with the OCR tool; 2. Merge and split using the PdfWriter class, merge multiple files through append() or add a specified page in a loop to achieve split; 3. Adding watermarks requires preparing a watermark PDF and overlaying it using the merge_page() method; 4. The encryption function sets password protection through the encrypt() method, which is suitable for daily batch processing needs.

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.

Article Introduction：PHP runs on the server side. When the user requests the page, the server executes the code through the PHP engine and returns HTML to ensure that the PHP code is not seen by the front end. 1. Request processing: Use $_GET, $_POST, $_SESSION, $_SERVER to obtain data, and always verify and filter inputs to ensure security. 2. Separation of logic and display: Separate data processing from HTML output, use PHP files to process logic, and template files are responsible for displaying, improving maintainability. 3. Automatic loading and file structure: Configure PSR-4 automatic loading through Composer, such as "App\":"src/", to automatically introduce class files. Suggested projects
