geefr-ppm 0.1.1

#Geefr's PPM lib

This crate provides a PPM writer, originally written for the 'ray tracing in a weekend' series.

#Creating a PPM

use ppm::Ppm;

// Create a ppm
let mut ppm = Ppm::new(width, height);

// Set a pixel
// origin is top-left
// r, g, b are 0-255 (u8)
ppm.set_pixel(x, y, r, g, b);

// Save to a file
ppm.write(String::from("foo.ppm")).expect("Failed to save PPM);
