Pages left in chapter for PDF conversion

[rfog]

I'm converting some ePub and mobi into PDF. I have a very custom header code to put Author and Title in even/odd pages, got from documentations with some little changes:

<header style="justify-content: center;font-size:x-small"><div class="even_page">_AUTHOR_</div><div class="odd_page"><i>_TITLE_</i></div></header>

However, I would like to have in footer the number of remaining pages in each chapter. Something like KOReade do in its footer. I don't mind if it is <remaining>/<total> or any other format.

Is there any way to do that? Thanks in advance.

There is currently no such facility though it could probably be added, open a bug report requesting it.

Done.

Thanks a lot if you are able or have time to implement it. And if not, thanks as well to have produced this fantastic software. (And it is real).

Wow!!

You are blazing fast!!!

[kovidgoyal]

You are welcome it was relatively easy to implement

Man, works like a charm.

Some samples.

A very easy and direct footer:

<footer><div>_TOTAL_PAGES_/_TOP_LEVEL_SECTION_PAGES_/_TOP_LEVEL_SECTION_PAGENUM_</div></footer>

Remaining pages in section:

<footer style="justify-content: center;font-size:x-small">
<div></div>
<script>document.currentScript.parentNode.querySelector("div").innerHTML =  ""+(_TOP_LEVEL_SECTION_PAGES_ - _TOP_LEVEL_SECTION_PAGENUM_ )</script>
</footer>

And the mother of all:

<footer style="justify-content: center;font-size:x-small">
<div></div>
<script>document.currentScript.parentNode.querySelector("div").innerHTML =  ""+ _PAGENUM_ +" of " + _TOTAL_PAGES_ + "/" +(_TOP_LEVEL_SECTION_PAGES_ - _TOP_LEVEL_SECTION_PAGENUM_ ) + " of " + _TOP_LEVEL_SECTION_PAGES_ </script>
</footer>

Attached a capture of one of my converted ebooks.

PS: Today my iMAC is going to be very bussy reconverting books.

I did some improvements and variations for footer.

Here: https://pastebin.com/KQXkv0ke

You can find 4 variations:

• <Current> of <total> / <current section> of <total section>
• <Current> of <total> (% read) / <current section> of <total section> (% section read)
• <Remaining> of <total> / <remaining section> of <total section>
• <Remaining> of <total> (% remaining) / <remaining section> of <total section> (% remaining of section).

(Select the one you want and paste in footer conversion field).

I've built 4 variations for a same book, read with each and personally I prefer second one as it is more natural. For "remaining" variation I need to think "oh, it is remaining, not current".
