MicroPNM is a small and efficient library for parsing PNM image formats in Rust. 🦀 It is designed to be minimalistic and highly optimized for resource-constrained systems, 🔍 making it suitable for embedded contexts and WebAssembly using the include_bytes! macro. 💪

At the moment, only reading of binary PPM (P6) is supported. 🚫

Add the following to your Cargo.toml file:

[dependencies]
micropnm = "0.1.0"

In your Rust code, use it like this:

use micropnm::PNMImage;

let raw_img = include_bytes!("./path/to/your/binary_image.ppm");
let ppm_img = PNMImage::from_parse(raw_img).unwrap();

// Get the image dimensions
let width = ppm_img.width();
let height = ppm_img.height();

// Get the maximum pixel value
let max_pixel = ppm_img.maximum_pixel();

// Get the image comment
let comment = ppm_img.comment();

// Get the RGB value of a pixel
let (r, g, b) = ppm_img.pixel_rgb(10, 20).unwrap();

MicroPNM is designed with minimal memory usage in mind. 💭 This makes it suitable for use in embedded contexts or in WebAssembly modules. 🕸️ The PNMImage type itself is simply a thin wrapper around a byte slice of raw image data. 💾
