pub fn create_output_file_name_with_output_dir(
    output_dir: &PathBuf, 
    base_dir: &PathBuf, 
    input_file: &PathBuf
) -> Result<PathBuf, String>

Calculates the relative filename according to base_dir and input_file and joins it with the output_dir.

Example

use {
    html5_picture::path::create_output_file_name_with_output_dir,
    std::path::PathBuf,
};

let output_dir = PathBuf::from("../new-assets");
let base_dir = PathBuf::from("../assets");
let input_file = PathBuf::from("../assets/some/picture.png");
let output_file = create_output_file_name_with_output_dir(&output_dir, &base_dir, &input_file).unwrap();
assert_eq!(output_file.to_str().unwrap(), "../new-assets/some/picture.png");
