Class.upload.php
This project is a server-side PHP library designed for managing file uploads and performing automated image processing. It provides a structured toolkit for ingesting, validating, and migrating files from temporary staging areas to permanent storage while enforcing security constraints.
The library distinguishes itself through a configuration-driven pipeline that executes a sequence of transformations on image buffers. It supports a wide range of geometric adjustments, including resizing, cropping, and rotation, alongside advanced visual enhancements such as watermarks, color adjustments, and stylistic border applications. By processing data as a continuous stream, the system maintains efficient memory usage during these operations.
Beyond basic file handling, the library includes comprehensive validation routines to ensure uploaded media meets specific dimension, pixel count, and aspect ratio requirements. It serves as a centralized utility for preparing web media assets, ensuring they are correctly formatted and visually consistent before they are stored or displayed.
