Obviously no animated gif support, but they're pretty common and it's quite possible some comics use them.

Amazon's "transition" to EPUB in favor of AZW3/MOBI is clever:

First they enforce a proprietary format, in favor of the open standard. MOBI is the child of Mobipocket which they acquired in the 2005. AZW3 is essentially a fancy MOBI. They published scant information over how these formats function internally, expecting you to use Kindle specific tools to generate them, but which have since been deprecated, and you can't read the documentation anymore. Said format falls out of use in favor of EPUB, which works everywhere else. They realize this, switch to it in a haphazard way, and officially deprecate MOBI (it still works, but it might not tomorrow). But the EPUB implementation is so half-assed it requires using the Mail to Kindle service. It almost seems designed to ensure people are gonna continue buying books from their walled garden instead of independent publishers which support it, while avoiding antitrust accusations, because other formats are "technically" supported — and it's doubly clever because it can also shut up people who have been begging them to support it for the past decade.

Complaining about what a evil, shitty monopolistic company they are doesn't change the fact that people still expect to be able to just transfer their files over USB. So it would be nice to support it.

Might be useful as a more reliable way to avoid issues with extra cover pages (eaa2541) and to ensure files are ordered.

Syntax:

book = epub.read_epub('file.epub')
images = book.get_items_of_type(ebooklib.ITEM_IMAGE)

Writing won't be supported (because RAR is a shitty proprietary format!) but reading should be possible (low priority for now though).

When --size is supplied if image is landscape it is resized not to width x height but to height x width. This losses sense if someone would provide to --size arguments such that width > height.

Some cbz archives has badly named files, which result in wrong order when reading on e-reader.
For example :
1.jpg, 10.jpg, 11.jpg should be renamed as 0001.jpg, 0010.jpg, 0011.jpg.
But without recompressing the files, only by renaming them.

Haley requested this, and it would in fact be very useful if you could join two CBZ files, representing a volume or a chapter, into a single one.

Some work would be needed to restructure how the end file is organized, and it might be useful to add each individual section to the table of contents when converting to EPUB.

The official KEPUB documentation by Ratuken suggests the <meta property="rendition:spread">auto</meta> tag for dual spread (landscape) images.

It might be worth investigating as currently I'm pretty sure images are just stretched and it might look bad.

The index [0] would be the first character of the path, which is not what we want

If a ComicInfo.xml (https://github.com/anansi-project/comicinfo) file is present in the archive conversion fails, if "--force" is used the file is not copied to the destination.

Ideally metadata files like this can be copied directly to the destination without processing.

Add profiles supporting fixed layouts for specific devices, so pages always fill 100% of the screen.

Wish there was a standard, universal way of achieving this :(

I;m getting this error, on mac. i tried diffrent size archives. same error,

PR: #20

images are resized to the exact output resolution without keeping their correct aspect ratio. ive attempted to fix this. ive tested with both up- and downscaling and it worked perfectly for me, but please test it for yourself first too. (i commented out the old method)
archive.py starting at line 131:

    # downscaling
    if (width > n_width and height > n_height
        and not options['nodown']):
        #img = img.resize((new_size), config.RESAMPLE_TYPE)
        img.thumbnail((new_size), config.RESAMPLE_TYPE)

    # upscaling
    elif not options['noup']:
        #img = img.resize((new_size), config.RESAMPLE_TYPE)
        width_ratio = (n_width/float(width))
        height_corrected = int((float(height)*float(width_ratio)))
        img = img.resize((n_width,height_corrected), config.RESAMPLE_TYPE)
        if img.size[0] > n_width or img.size[1] > n_height:
            img.thumbnail((new_size), config.RESAMPLE_TYPE)

For --resize, it would be convenient to be able to specifiy just one or the other dimension and have the other one be automatically set to preserve aspect ratio, like ffmpeg does for video.

Maybe this would interact negatively with how the software interprets landscape images?
