Function lodepng::decode_file [−] [src]

pub fn decode_file<P: AsRef<Path>>(
    filepath: P, 
    colortype: ColorType, 
    bitdepth: c_uint
) -> Result<Image, Error>

Load PNG from disk, from file with given name. Same as the other decode functions, but instead takes a file path as input.

decode32_file and decode24_file are more convenient if you want specific image format.

There's also State::decode() if you'd like to set more settings.


 match decode_file(filepath, ColorType::RGBA, 8) {
     Ok(Image::RGBA(with_alpha)) => do_stuff(with_alpha),
     Ok(Image::RGB(without_alpha)) => do_stuff(without_alpha),
     _ => panic!("¯\\_(ツ)_/¯")
 }
