EPUB not displayed properly in Prestigio 3162 - Page 2

DiapDealer · 03-11-2012, 08:05 PM

What output profile are you using when you do your calibre epub->epub conversion that results in an ePub that behaves correctly on your device? That calibre output profile may be adjusting for some known quirk of your device behind the scenes. Like a flat(ter) directory structure for one thing. It sounds to me as if the css file just isn't being found/used.

Someone would probably have to compare the Sigil-built epub to the working converted calibre epub to see exactly what the differences are (you won't be able to view the changes calibre may be making to the epub with Sigil, since Sigil will automatically restructure the epub to its own requirements as soon as you first open it).

Add the Sigil built epub to calibre and before you do anything to it, use the Tweak Book function to explode the epub and take note of the directory structure. Then after you do the epub->epub conversion... use Tweak Book again to see if the overall structure has changed (I'm betting it has).

It may well be that you won't be able to use Sigil-built epubs straight out of the box on that device... since its internal directory structures are carved in stone and can't be altered.

Good luck!

Hitch

This is my style declaration I must admit I relate to css stylesheet withing the document but i usually add few more styles on the page when I want to override current settings. This is how the header looks like:

Code:

<?xml version="1.0" encoding="utf-8" standalone="no"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN"
  "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
  <title></title>
  <link href="../Styles/Stylesheet.css" rel="stylesheet" type="text/css" />
  <style type="text/css">
/*<![CDATA[*/

  p.sgc-2 {font-style: italic; padding-top: 0.5em}
  p.sgc-1 {text-align: center; text-indent: 0;}
  /*]]>*/
  </style>
</head>

I am a kind of a beginner with it and trying to keep it as simple as it can be. I converted it with Calibre for Kindle it worked perfectly, it worked fine for EPUB reader for Android. In SONY epub it had some issues with special letters used in Serbian but that is another issue we have with EPUB on Sony. But all styles were preserved. I will try to see if I can post this book, but if not I will do the same with few chapters of another book so that you can see what is going on. Because this reader is doing the same with almost all epubs (not only mine) made in Sigil.

The CB · 03-12-2012, 06:23 AM

@DiapDealer I will have to check all that. And compare all data. Then I will be back with detailed report and probably one book made in two ways so we can see what is going on.
Thank you I never used tweak book before i will have to see how it works.

Perkin · 03-12-2012, 12:12 PM

Just read through some of this, could it just be that Sigil puts stuff in folders, whereas calibre flattens the file structure?

Convert a file in calibre, test it works on device, then load it into Sigil and do a save straight away, then load that onto device and check.

Edit:
Just read that DiapDealer suggested that, missed seeing it on first read through.

Of course you are right. But on the other hand, we are talking about a device with a somewhat "wayward" software, right ? My focus was to see, which changes calibre mades, and this is one of the most obvious.

Sometimes its useful to have a look on improbable things.

@CB: The method DiapDealer suggests "Someone would probably have to compare the Sigil-built ..." is probably the only way to find the truth. It's very tedious, so if possible check with another Prestigio if the fault exists there as well. And reduce the size of your source to the absolute minimum, which is needed to reproduce the error.

The CB · 03-12-2012, 06:20 PM

@mmat I am preparing enitre project "How to find what Calibre does to make prestigio read EPUB" :-) I will post here the results. And I hope I will find the solution.

The CB · 03-14-2012, 06:31 PM

So here I am coming back again. Problem is still on. My further investigation showed that any Prestigio e-ink reader can't display or at least not entirely epub made in Sigil. Sometimes it displays only two pages, or it doesn't show formatting. You can make it anywhere but if the last save is in Sigil you are done, you have to reconvert it again using Calibre. This is the first time for me posting the link here because I wanted you guys to take a look at these examples i hope it is ok if I use my dropbox. Here I am posting parts of the project of some collection. Only few pages I put here.

This one is original made in Sigil and saved in Sigil. Prestigio displays only 2 pages, no proper formatting

Code:

http://dl.dropbox.com/u/27794013/Sirius%2085a.epub

This one is made in Sigil reconverted in Calibre. Prestigio displays formatting a bit strange but sees all

Code:

http://dl.dropbox.com/u/27794013/Sirius%2085c%20-%20sftim.epub

there are differences but I have no idea if those could make such huge change.

It's a bit late for today, i will have a close look on your favorite

project tomorrow.

But just one question: if you take the Calibre-Book (85c) and save it once with sigil, the problem is there again, did i understand correctly ??

Btw: The cover image (85c) is somewhat distorted. Do you know the option on calibre convertion-settings "preserve aspect ratio" ? It's on the epub-output page.

The CB · 03-14-2012, 07:13 PM

Yes if I take 85c again in Sigil the problem appears again. yes the picture is distorted but in reader if any it looks ok so I didn;t bother with that.

DiapDealer · 03-14-2012, 09:29 PM

I'd say that's pretty good evidence that the Prestigio just can't properly display epubs that conform to Sigil's particular directory structure (which it forces every epub it opens to conform to).

Unzip both samples and notice the drastic difference in structure.

The CB · 03-15-2012, 06:16 AM

So far I came to conclusion when making EPUB using Sigil in the same way one converts EPUB to MOBI for Kindle users it should be converted to EPUB for Prestigio users. At least it is not my fault :-)

Toxaris · 03-15-2012, 06:31 AM

It is rather silly that apparently the Prestigo does not support the folder structure of the ePUB's created by Sigil. It is according to specs and very logical.

Unfortunately that is obviously exactly what happens. I am not fun of Prestigio but that is the only e-ink reader that you can buy in my country and it is rather expensive comparing to other readers you can find on internet... but that is not the subject here. I am planning to write to them and see about the software they put on their device. But I am still hoping someone here would come up with some solution.

Perkin · 03-15-2012, 09:27 AM

You might be able to ask kiwidude in the calibre plug-in forum if he could add a flatten epub folder option to his wonderful 'modify epub' plugin, that way you'll only have to do that rather than a complete convert which doesn't always preserve everything.

There is an option to flatten the epub in the output options (for FBReader), so he may just be able to hook into that.

I guess we should make a final check. This one is 85a with a rebuilt "Calibre - style File structure", but nothing else.

How does it look on your prestigio ?

Btw. I noticed callibre tossed out the "title"-tag from any file within the "Text"-folder. Huh ??? What's this ????

yes the picture is distorted ....

but it won't hurt just to check it either ??
