ODT -> Pdf Headers but omit on some pages

[Alec Ford]

I want to have headers on my pdf output but not on the first few pages. I’m have a little knowledge in Java Script and HTML and figure from the examples that this should be possible and quite simple but my skill level isn’t up to it. Maybe I’m not asking the right questions in my searching but I can’t find anything. Any help appreciated

IIRC PDF uses Postscript internally not HTML.

But maybe you don't need calibre to convert an ODT to PDF. One of the better features of Libre Office Writer is producing PDF's.

In Word I would make use of a Section to suppress page numbers on the front matter pages. Writer has Sections, given Writer started life as reverse engineered Word '9? it's quite likely its Sections are a clone of Word's Sections.

Use the following header template:

<p id="pagenum"></p><script>if (_PAGENUM_ > 5) document.getElementById("pagenum").innerHTML = "" + _PAGENUM_</script>

Change 5 to whatever number of pages you want to skip headers for.

Thanks, I should have explained a bit more, I want to take the example for title and author and put that in place of page (in your code above but I'm just not sure how to do it. Perhaps what I tried had some silly mistake but I couldn't get it to work

<p style="text-align:right"><span class="even_page">_AUTHOR_</span><p style="text-align:left"><span class="odd_page"><i>_TITLE_</i></span></p>

<p id="pagenum"></p><script>if (_PAGENUM_ > 5) document.getElementById("pagenum").innerHTML = _TITLE_ + " " + _AUTHOR_</script>

And you can change the _TITLE + " " + _AUTHOR_ to whatever fancy HTML snippet you like.

Thanks, but, well I can get this to work

<p id="pagehead"></p><script>if (_PAGENUM_ > 1) document.getElementById("pagehead").innerHTML =  "Page "+ ( _PAGENUM_ -1) </script>

As soon as I try any property other than _PAGENUM_ I get nothing out

You have to put the other properties in quotes, like this

"_TITLE_"

because they are strings, not numbers.

Ah - that explains it, I haven't the mindset for JavaScript and when you need quotes or not.

So this is what I ended up with, maybe there's a better way. It puts page headers alternating between author and title starting at page 3

<p id="pagehead" style="text-align:center; font-size:x-large"></p><script>if ("_PAGENUM_" >2 ) {if ("_PAGENUM_" % 2 === 0) {document.getElementById("pagehead").innerHTML = "_AUTHOR_" }else {document.getElementById("pagehead").innerHTML = "_TITLE_"}}</script><p

_PAGENUM_ must not be in quotes

It works for me both ways for me, with or without quotes, I don't know enough about JavaScript to explain it but I would agree it would be better practice to remove them.
