EPUB output

[davotibarna]

I did what dwanthny suggested, set up a short script and run the conversions on the command line in debug mode. Surprise: all of them got converted correctly. Then I run the GUI conversions again and realized 2 things:

1. Bela.lrf
The "Extra CSS" was set under preferences but when I run the conversion for this ebook, the "Extra CSS" field was empty in the conversion dialog under "Look & Feel". Hmmm.... it must mean that Calibre remembers a kind of "conversion profile" for each ebook which was converted before? This individual conversion profile must overwrite the global preferences.

2. SG.hu.lrf
I cannot explain this. It's great if I run this from the command line, but this line is missing from the style (in xhtml) when I run it from the GUI:
src: url(res:///system/media/sdcard/myfonts/LiberationSerif-Italic.ttf)

So CL version has this style:
@font-face {
font-style: italic;
font-family: "LiberationSerif", serif, sans-serif;
font-weight: normal;
src: url(res:///system/media/sdcard/myfonts/LiberationSerif-Italic.ttf)
}

The GUI version is lacking:
@font-face {
font-style: italic;
font-family: "LiberationSerif", serif, sans-serif;
font-weight: normal
}


I've doublechecked the parameters, I believe I use the same for both the GUI and CL.

Important part is "should". No guarantees, when it comes to that, I'm afraid. The difficulty of just applying css and having it override pre existing styles is one of the reasons that I haven't yet written font embedding for EPUB yet.

Basically, to do it, I have to go through all the css, remove font-family definitions and replace them with user specified ones. Then there is the problem of figuring out when a font-family should be left alone and when it should be replaced.

There's a section in the User Manual about how conversion options are stacked. At the start of any conversion, the final used options are printed out, compare them from the CLI and the GUI to see what is different.

Where are the final used options printed out? I can't see them in the debug log.

Right at the beginning, it looks like this
Note on the command line you have to add -vv

This is true, every time I go back to reconvert a book that I previously converted the default settings are the settings I used to convert the book originally.

That's the extent of my knowledge in this area.

I'll be lurking hoping to learn something.

Good Luck!

Hi, i was wondering, could anyone tell me more about this validation error, unknown element "u" from namespace "http://www.w3.org/1999/xhtml"?

I'm trying to find out what it is, if i can delete it, and how it might possibly be giving me the content locked message on the kobo.

If this is an error message from epubcheck, it should also give a filename and a line number. Look there.

Could this be it? As far as i can tell i'm at the correct line.

<span class="calibre3"><u class="calibre4">[1]</u></span></p><div class="calibre2"></div>

Yes, that's the line. ePub is based on XHTML 1.1.
http://www.w3.org/TR/xhtml11/

the underline <u> tag was deprecated in XHTML 1.0 Transitional, and removed from XHTML 1.0 Strict and XHTML 1.1

Try changing
<u class="calibre4">[1]</u>
to
<span class="calibre 4" style="text-decoration:underline">....</span>

Or better still, convert it to a hyperlinked reference and you will get the "underline" for free.

(Aside: I personally would avoid using underlines for emphasis as they are too easily confused with hyperlinked text [and one would expect to see/use hyperlinks within XHTML documents.]

Nothing more frustrating than trying to "tap" a decorative underline.. )

Seems that the latest version of calibre fixed this. Thanks anyway

hello to all,
I am new at this forum and I have a question,
I loaded Calibre yesterday , I try to convert pdf to epub but Turkish characters don't display correctly.I asked this question to them and they sent me here


''I'm new at Calibre, I convert pdf to epub but Turkish chracters don't display correctly, I write at Input character encoding as UTF-8 but it doesn't effect. What can I do for proper display of Turkish chracters?''

''-You have to embed the correct fonts in the epub. AT the moment calibre does not support font embedding, so you have to do it by hand. See the epub forum in mobileread.com for help''

How can I embed characters by hand?
Thanks
