Thumbnailator is a Java image thumbnailing library designed for generating resized images with aspect ratio preservation and high-quality scaling. It serves as a toolkit for rotating, cropping, and adjusting the opacity of images within Java applications. The library is distinguished by its ability to function as an Exif-aware image processor, automatically rotating thumbnails based on embedded orientation metadata. It also provides specialized utilities for digital watermarking, allowing secondary images and branding markers to be overlaid with adjustable transparency. Core capabilities cov
This is a JavaScript image loading library and a suite of utilities for binary metadata parsing and canvas-based transformations. It provides a unified interface for loading images from URLs, Blobs, or Files into HTML elements. The library includes a canvas-based image transformer for producing scaled, cropped, or rotated images and an image orientation handler that rotates or flips images based on embedded metadata. It also features an Exif metadata parser to extract IPTC and Exif tags and embedded thumbnails from binary image data. The toolset covers browser-based image processing, includi
Webuploader is a browser-based file upload library written in JavaScript. It provides a system for managing multi-file uploads with support for drag-and-drop, clipboard pasting, and type filtering. The library includes a chunked file upload manager that splits large files into smaller segments to improve stability and enable partial retries. It features a client-side image compressor that generates previews and reduces file size before transmission, as well as an MD5 file integrity verifier to identify and skip redundant uploads of files already stored on the server. The tool manages file co
Imaging is a Go library for image processing that provides a set of functions for common image manipulation tasks. It offers capabilities for adjusting image colors, applying convolution filters, blurring, cropping, resizing, sharpening, and correcting orientation based on EXIF data. The library supports resizing images to exact dimensions or bounding boxes with aspect ratio preservation and configurable resampling filters. Color adjustments include gamma, contrast, brightness, and saturation controls, while blurring and sharpening use Gaussian-based algorithms with configurable sigma paramet
