pdf conversion questions

[balubeto]

Hi

I installed Calibre 3.18 64 bit on Windows 7 SP1.

I should convert some books from azw3 or epub format to pdf format.

I have two questions:

1) How do I keep the link clickable?

2) How do I numerate the pages so that I can decide which is the first page? By chance, is it also possible to enter the Roman numbering so that Roman numbers can be inserted in the first pages, and then the Arabic numbers?

Thanks

Bye

links remain clickable automatically and you can write arbitrary javascript code to output page numbers https://manual.calibre-ebook.com/con...verting-to-pdf

In the scripts listed in that document, I did not find a script that first inserts the Roman numbers and then, from a specific page, enters the Arabic numbers. So how do I create this script?

Thanks

Use an if statement to condition the output. I'm afraid I dont have the time to write the script for you.

Could anyone do this script?

Thanks

Can the script be multiline and include variable declarations?

I'm thinking that your example can take care of the Arabic numerals, (using _PAGENUM_ - N, where N is the number of Roman pages), and then the Roman numerals could use a simple array of text elements predefined for the max no. needed. This is usually a small number and would be easier than writing a full conversion.

Yes it is an arbitrary JS script.

This works in a web browser so may work as a template for calibre.

You need to extend the ronu list as far as needed, and set romp to the number of roman numeral pages at the start of the book.

<p id="pagenum" style="text-align:center;"></p>
<script>
  var ronu = [ "-", "i", "ii", "iii", "iv", "v", "vi", "vii", "viii" ]
  var valu = ""
  var romp = 6
  if (_PAGENUM_ > romp)
    valu = _PAGENUM_ - romp
  else
    valu = ronu[_PAGENUM_]
document.getElementById("pagenum").innerHTML = valu
</script>

If you make ronu as big as you think you'll ever need, (e.g. 20 roman numerals), then you just need to change romp for each book.
