Function lodepng::encode24_file

pub fn encode24_file<PixelType: Copy, P: AsRef<Path>>(filepath: P,
                                                      image: &[PixelType],
                                                      w: usize,
                                                      h: usize)
                                                      -> Result<(), Error>

Same as encode_file, but always encodes from 24-bit RGB raw image
