ToCBZ adds helper scripts to make it easier to convert image folders into "cbz" and "cb7" files. "cbz" and "cb7" are file formats compatible with the most popular "comic readers" around, like mcomix and okular.
>>> to_cbz.py image-folder # image-folder.cbz
>>> to_cb7.py image-folder # image-folder.cb7
>>> to_7z.py image-folder # image-folder.7z
>>> to_cb7.py * # all folders are converted to cb7
cbz and cb7 are equally compatible with comic readers. The big difference between then is the trade-off. cbz files are larger, but faster to load, while cb7 are smaller, but much slower.
Convert your folders to the format that is most convenient to you.
