mobi conversion - kindle chapter marker issues

foghat · 09-28-2010, 09:50 PM

Hi all,

I have a handful of epub's that I am converting to MOBI.

While a TOC is generated that can be read in the Calibre viewer and is also viewable and works on the kindle (even though the TOC is at the end of the book), I do not get chapter markers on the kindle's progress bar.

Based on the convert log, it looks like there is some issue with the TOC, but no idea what the message means and if this could be causing the marker issue.

Any thoughts?

I think this is the problem. Calibre uses the toc.ncx to generate the chapter marks IIRC. Does the ePub have a toc.ncx?

foghat · 09-28-2010, 10:49 PM

Yes it does....

Here is a snippet from the toc.ncx:

<?xml version='1.0' encoding='utf-8'?>

The problem is that the TOC.NCX sequence needs to be the same as the order of files in the spine in the .OPF file. "Time to be Men" is out of sequence.

If your TOC.NCX points to multiple anchors within a file, the sequence has to be in the order they appear in the file. Note that you can have a textual TOC with entries in any order you want, but the TOC.NCX has to conform to the order of files/anchors in the source file(s).

Not at home now so can't take a look at the .OPF file - but are you saying I can view the contents of the .OPF file and said contents should have some sort of file 'list' or order that can be mapped back to the toc.ncx? And that I need to rearrange the items in the toc.ncx to match the order of the .OPF?

If so, is just as simple as physically rearranging? Or does the playOrder just need to be changed to the correct order?

Or am I way out here?

GRiker · 09-29-2010, 09:24 AM

Within the OPF file is the <spine>, which describes the order of files as displayed to the user if you simply page through the epub. Within the HTML files listed in the spine, the order of the anchors is significant.

Within the TOC.NCX is the <navMap>, which describes the order of chapter marks/index points. Within the navMap, the order of the <navPoints> is significant.

A MOBI file requirement is that chapter marks (index points) are sequential within the book. In other words, when toggling right to jump to the next chapter, that destination must be the next indexed point in the MOBI file.

Therefore, when converting from EPUB to MOBI, it is necessary to have the layout of the HTML (and the anchors they contain) correspond to the sequence of <navPoints> in the TOC.NCX file.

If you open DarkTowerVWolvesofCal_17963.html, you will find that the anchor #Il01 is earlier in the file than #Ch31, which is causing the disruption in the space/time continuum.

You have two choices:

Rearrange the order of the TOC.NCX navPoints to correspond to the order of the anchors in your HTML file(s). It's not a matter of simply changing the playOrder attributes, the navPoints themselves must be in the correct order.
Rearrange the HTML file(s) so that the anchors (and the text they represent) are in the same order as the navPoints in your .NCX file.

My guess is that it would be easier to edit the .NCX file to match the layout of the HTML file(s).

Thanks for the detailed explanation. Will give things a go when I get home.

foghat · 09-29-2010, 06:30 PM

Okay, I am getting a bit confused. I have no file called just: DarkTowerVWolvesofCal_17963.html

They are all"
- DarkTowerVWolvesofCal_17963_split_001.html
- DarkTowerVWolvesofCal_17963_split_002.html
- etc.

However, when I look at content content.opf, within the spine tag I have:

<spine toc="ncx">
<itemref idref="titlepage"/>
<itemref idref="jacket"/>
<itemref idref="html53"/>
<itemref idref="html52"/>
<itemref idref="html51"/>
<itemref idref="html50"/>
<itemref idref="html49"/>
<itemref idref="html48"/>
<itemref idref="html47"/>
<itemref idref="html46"/>
<itemref idref="html45"/>
<itemref idref="html44"/>
<itemref idref="html43"/>
<itemref idref="html42"/>

This continues sequentially down to html1

Given this descending order and the example from my toc.ncx above, do I need to rearrange all the entries in the toc.ncx to be in this descending order?

Or do I keep the toc.ncx in ascending order, but just rearrange the <navpoints> that are currently out of sequential order?

Thanks.

Edit:

Figured it out, just had to put the items in ascending order in my toc.ncx. Now I have chapter markers. Ya! thx. for the help.

Good job. The universe is restored.
