Hello,
This is not really a problem, but it's a little bit annoying and if you have time I would appreciate if you would look into it. I am not even sure if this would be your supported configuration.
Since I want the manga feature in Kindle, and I just refuse to connect my Kindle to the internet, I have been side-loading my manga. As you would know, I need to convert them to KFX for the manga feature.
So far my process has been:
- Extract images file from KF8 file download from Amazon
- Post-process the image with KCC using CBZ output. Extract the CBZ.
- Use Kindle Create to create "Comics" type book. Import all images. Add table of contents.
- Generate KPF from Kindle Create
- Convert KPF to KFX using your plugin CLI interface
Everything works fine, except for the cover page of the KFX file. The first image in the book (the first page) will be display as cropped on actual Kindle (PPW3 7th gen). I have checked the KPF file with Kindle Previewer, and it displays fine. The cover display in library is okay, since I believed that's handled by calibre.
If you would want to look into this, I can send you the KPF file via email. It's definitely not in public domain. It's really not a big deal though.
