Count Pages plugin for calibre fails me for comic books in format cbr and cbz. It estimates about 1/6 of the actual pages.
These formats are .rar (cbr) or .zip (cbz) files with the jpgs of the scanned pages. It should be easy to know how many pages (jpgs) has the compressed file.
The versions I use are:
- Calibre 0.8.59 for windows
- Count Pages plugin 1.5.0
Thanks a lot.
