GNOME Bugzilla – Bug 579402
Add support for CBA (Ace-compressed) comics
Last modified: 2017-07-19 15:25:49 UTC
originally sent to launchpad: https://bugs.launchpad.net/ubuntu/+source/evince/+bug/307751 Evince supports comicbook files in .cbr format (for rar archives) and .cbz (for zip). But not other less usual formats like cb7, cbt or cba, which are actually just renamed 7zip, tar and ace files; all of them, unlike rar, supported by ubuntu out of the box. Could support for these filetypes be added?
cb7 is already fixed: http://bugzilla.gnome.org/show_bug.cgi?id=532312 about cba, and cbt, I wonder if they need to be supported really.
cbt is fixed as well: https://bugzilla.gnome.org/show_bug.cgi?id=588266
Confirmed that it works for cb7 and cbt. Thanks to the devs for this. Suggestion, Could this bug be closed, and maybe just open an enhancement for cba-files if someone requests it? Because, do evince really need support for cba files which is compressed ace files. The format is properitary, and altough there exists an "unpackace binary blob" for linux, there's no packer. see http://www.winace.com/ (Also tried to find cba files on the net, but couldn't find a single cba file in the wild)
Add support for unace should be not hard. However, it is necessary a file to test with. Considering .cba is the only format missing, I am going to leave as NEEDINFO until a test file were uploaded.
Created attachment 248055 [details] compressed ace file with extension .cba for testing Ran Commandline Ace 2.6 from their website in dosbox, and was able to create an .ace file which i then added the .cba extension to. The attached file contain images of the debian and gnome logos.
I've never seen one of those (or cb7 or cbt for that matter) in the real world. So given that comment 3 confirms my impression, and that there appears to be no decompression tools available for it under Linux, I'll close this. CBT and CB7 support was already added in 2010.
