Example

See example.py for more example.

# A slightly slow, automatic method. The default method.
# Possibly produces a smallest impak file, but it really depends.
with impak.create("Ganyu X Slime_lto.impak",
                  mode="lto", codec="webp", quality=95
                  ) as pack:
    for path in tqdm(paths, desc="Encoding using impak"):
        pack.add(path, name=path.stem)

# A fast and straight forward, automatic method.
# Results in a slightly larger impak file.
with impak.create("Ganyu X Slime_prior.impak",
                  mode="vs_prior", codec="webp", quality=95
                  ) as pack:
    for path in tqdm(paths, desc="Encoding using impak"):
        pack.add(path, name=path.stem)
