epub to pdf - no page numbers on first pages

[berchas]

Hi, how can I add page numbers but remove them from the first pages? E.g. the first four pages are completely blank, and page numbers appear only after that.

I tried the approach described here: https://www.mobileread.com/forums/sh...+numbers+pages

No luck. I get error messages as follows and no page numbers appear anywhere. KR

You haven't posted your code, so without that, it's difficult to provide an exact answer.

I applied the following (and variants of it):

ebook-convert in.epub out.pdf --pdf-header-template '<header><div id="pagenum"></div><script>if (_PAGENUM_ > 5) document.getElementById("pagenum").innerHTML = "" + _PAGENUM_</script></header>'

The if condition seems to cause the mentioned errors.

The code given in the documentation works fine, e.g.:
'<header><div></div><script>document.currentScript.parentNode.quer ySelector("div").innerHTML = "" + (_PAGENUM_ + 3)</script> </header'

However, it only shifts page numbers. I want to remove them from the first pages.

I'm sure you don't need this anymore, but if this is helpful to others in the future, I got this working.

I'm using Python for stuff, but hopefully you can see what I'm doing here and modify it for your purposes, minus the Python stuff. Should be straightforward to just create the command line option (i.e. you do not need Python for this):

        # Define footer templates with JavaScript to hide page number on page 1
        # Note the use of single quotes for the outer HTML attributes and escaped double quotes for JavaScript strings if needed.
        centered_footer_script = "if (_PAGENUM_ === 1) { var el = document.getElementById('pn_center_id'); if (el) el.innerHTML = ''; }"
        centered_footer_html = f"<footer><div id='pn_center_id' style='margin: auto; font-size: smaller;'>_PAGENUM_</div><script>{centered_footer_script}</script></footer>"

        # The entire template string needs to be quoted for the command line.
        cmd_parts.append(f'--pdf-footer-template="{centered_footer_html}"')
