tinyppm

Simple .ppm loader written in Rust.

This is more of a toy project, I have written, to be able to easy reuse it for some of my experiments with 2d graphhics in Rust.

Usage

1. Add tinyppm to your Cargo.toml
2. Call read_image_data:

```rust extern crate tinyppm;

fn myfunction(filename: &String) { let (width, height, image) = tinyppm:ppmloader::readimagedata(filename); // image contains 32bit image data }

```

Details:

tinyppm supports only 'raw ppm' format (the most popular format of ppm. More details: ppm format specification ).

Another restriction that is important is that at them moment tinyppm supports reading only truecolor (24bpp - 3 color channels, 8b per channel) images. After the image is read it is converted to RGB+A format (32bpp) so that it is ready to be pushed directly to framebuffer.

Additional examples:

If you want to check how it works, please have a look at ppm_viewer which is simple image viewer written in Rust: https://github.com/MaciekTalaska/2deffects/tree/master/ppmviewer
