Crate imagefmt

Example

extern crate imagefmt;
use imagefmt::{ColFmt, ColType};

fn main() {
    // load and convert to bgra
    let _pic = imagefmt::read("stars.jpg", ColFmt::BGRA).unwrap();

    // convert to one of y, ya, rgb, rgba
    let pic = imagefmt::read("marbles.tga", ColFmt::Auto).unwrap();

    // write image out as grayscale
    imagefmt::write("out.tga", pic.w, pic.h, pic.fmt, &pic.buf,
                                                 ColType::Gray)
                                                     .unwrap();

    // get width, height and color type
    let _info = imagefmt::read_info("hiisi.png").unwrap();
}

There are also format specific read and write functions which are more flexible. With the write functions, set the last argument to None to write the whole image or see source code for write_region for an example to write only a region. Use std::io::Cursor to read and write in-memory images.
