High-performance, cross-platform Rust/WebAssembly image processing library

## 📝 Table of Contents - [Get Started with WebAssembly](https://github.com/silvia-odwyer/photon#-get-started-with-webassembly) - [Get Started Natively](https://github.com/silvia-odwyer/photon#getting-started) - [Documentation](https://docs.rs/photon-rs/0.1.0/) - [Official Website.](https://silvia-odwyer.github.io/photon/) - [All Available Functions.](https://silvia-odwyer.github.io/photon/docs/photon/all.html) - [Got Questions? Ask Here!](https://github.com/silvia-odwyer/photon#got-questions) Photon is a high-performance Rust image processing library, which compiles to WebAssembly, allowing for safe, blazing-fast image processing both natively and on the web. ### Features - **Fast:** Photon outperforms even the fastest of libraries, including ImageMagick. On the web, its high-performance allows for near-native-speed image processing on the web. Benchmarks coming soon. - **Call with JS:** Want to use Photon on the web or with Node? Using a simple npm package, you're good to go. Get all the benefits of WebAssembly with zero-cost abstraction. - **Use Natively:** For command-line apps, native photo editing apps, and so forth, Photon's core codebase is in Rust, allowing for cross-platform development. ### Live Demo View the [official demo of WASM in action](https://silvia-odwyer.github.io/photon/demo.html). ### Get Started #### Getting Started Guide Check out Photon's [getting started guide, complete with tutorials, installation instructions, and more](https://silvia-odwyer.github.io/photon/guide) #### Documentation ### 📚 Documentation View the [official documentation](https://docs.rs/photon-rs/). ### Photon In Action ![Imgur](https://i.imgur.com/PShSZ6k.png) ### Functionality 96+ customisable functions are available. Resize, transform, correct, and filter images: apply as many effects as desired. Functions include: - **Image correction**: Hue rotation, sharpening, brightness adjustment, adjusting saturation, lightening/darkening all within various colour spaces. - **Convolutions**: Sobel filters, blurs, Laplace effects, edge detection, etc., - **Channel manipulation**: Increasing/decreasing RGB channel values, swapping channels, removing channels, etc. - **Transform**: Resize, crop, rotate and flip images. - **Monochrome effects**: Duotoning, greyscaling of various forms, thresholding, sepia, averaging RGB values - **Colour manipulation**: Work with the image in various colour spaces such as HSL, LCh, and sRGB, and adjust the colours accordingly. - **Filters**: Over 30 pre-set filters available, incorporating various effects and transformations. - **Text**: Apply text to imagery in artistic ways, or to watermark, etc., - **Watermarking**: Watermark images in multiple formats. - **Blending**: Blend images together using 10 different techniques, change image backgrounds. ## Install ### Native Add the following line to the dependencies section of your Rust project's Cargo.toml: ###### Cargo.toml ```toml [dependencies] photon-rs = "0.3.2" ``` ### Web Install Photon as an npm module: ```bash npm install --save @silvia-odwyer/photon ``` ### Node.JS To install Photon as an npm module for Node.JS use: ```bash npm install --save @silvia-odwyer/photon-node ``` #### Using Photon Natively The following code opens an image from the filesystem, applies an effect, and saves it. Here is a code sample to get you started: ```rs extern crate photon_rs; use photon_rs::native::{open_image, save_image}; fn main() { // Open the image (a PhotonImage is returned) let mut img = open_image("test_image.png"); // Increment the red channel by 40 photon_rs::channels::alter_red_channel(&mut img, 40); // Write file to filesystem. save_image(img, "raw_image.jpg"); } ``` [For more examples, check out the guide on how to get started with Photon natively.](https://silvia-odwyer.github.io/photon/guide/using-photon-natively/) #### Using Photon On The Web ## Modules Photon contains a series of modules, which include: - `effects`: Various image effects, including adding offsets, thresholding, duotoning, solarization, etc., - `channels`: Functions related to increasing/decreasing the red, green, and blue channels of the image data. - `transform`: Resize, crop, flip, and rotate images. - `filters`: Preset filters, which alter the RGB channels of the image. Contains over 20. - `conv`: Laplace, Sobel, emboss; image proc functions which require image convolution. - `noise`: Noise generation of varying tints and hues. - `multiple`: A module for dealing with multiple images, such as watermarking images, etc., - `correction`: Hue rotation, adjusting saturation, lightening/darkening: all techniques available in multiple colour spaces, which lead to varying effects. All effects and filters can be viewed below and on the official website. ### Run Examples Clone this crate's official GitHub repo: ```sh git clone https://github.com/silvia-odwyer/photon ``` Run the binary, which will perform an image processing function on an image: ```sh cd crate cargo run --release ``` Compare the original image with the outputted image, and you'll see the desired effect has been applied. ### Got Questions?
