Hello,

This is a follow up of two points in a previous discussion in this thread.

I wrote it, or at least I wrote a module which delete the epub format without further prompting, leaving only the AZW3 format I wanted. Should I post the code here if it can be useful to someone?

I tried to implement a module from the custom action capnik mentioned, using the code to select the correct ebooks from the ones selected in the Library view. I also located the Calibre code behind the button I am clicking on manually: it is in https://github.com/kovidgoyal/calibr...dgets.py#L1228 on line 1135.

With this information, I wrote:

from calibre.ebooks.covers import generate_cover
from calibre.ebooks.metadata.meta import metadata_from_formats
from calibre_plugins.action_chains.actions.base import ChainAction

class CustomCover(ChainAction):

    # replace with the name of your action
    name = 'Custom cover'

    def run(self, gui, settings, chain):
        db = gui.current_db.new_api
        rows = gui.current_view().selectionModel().selectedRows()
        book_ids = [ gui.library_view.model().db.id(row.row()) for row in rows ]
        for book_id in book_ids:
            mi = metadata_from_formats(paths)              
            cdata_before_generate = current_val
            current_val = generate_cover(mi)

which does... nothing! Could someone point me in the good direction? (If it is too much of a request, let me know, I am not sure yet about the rules on this forum )

Thank you!
