Is there any difference between the result of option 1 vs. 2? I know option 2 can introduce additional changes - such as adding a cover page or removing a cover, controlling page breaks, removing header/footers, etc. Do these changes happen with option 1? |
I have wondered about a relative of this question. Hope that I am not too OT.
I run into the situation where I want my epub to have the correct metadata (contain the correct OPF). Sending the book to a folder does this update. I send, delete the format, then add the 'sent' version back into the book.
This works well enough for me, although clunky.
However, sometimes I want to add/update a jacket. I would be very happy to have an operation that updates the OPF and adds the jacket page to the spine. Unfortunately, I don't have that, so I am left with convert epub->epub. The conversion makes me nervous because I am not certain that formatting will not change. I don't want any margin changes, TOC changes, font changes, or any other changes to the book content. I just want the new jacket and the OPF. Being paranoid, I usually end up doing nothing.
If someone knows the epub->epub conversion option settings that ensure an absolute minimum of formatting changes, I would love to hear them.
