Photon
Photon is a high-performance image processing library written in Rust. It serves as a pixel manipulation toolkit and image format transcoder, providing a WebAssembly graphics engine for executing visual effects and transformations directly within web browsers.
The project is built around a functional image pipeline, which allows for the programmatic chaining of sequential transformation operations. This architecture supports the creation of complex visual effects through a coded pipeline.
The library covers a wide range of image processing capabilities, including color management across multiple color spaces, geometric transformations such as resizing and cropping, and composition tools for image blending and text rendering. It also includes a suite of visual effects featuring convolution filters, noise generation, and monochrome conversion.
The toolkit supports decoding and encoding for industry-standard formats including PNG, JPEG, BMP, TIFF, and WebP, and provides utilities for converting image data to and from base64 strings.
