Question

ADE displays EPUB cover as thumbnail

I'm editing a Calibre-generated EPUB 3 file. The cover page is perfectly ordinary:

<body>
<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" version="1.1" viewBox="0 0 573 862" preserveAspectRatio="xMidYMid meet" width="100%" height="100%">
  <image width="573" height="862" xlink:href="cover.png"/>
</svg>
</body>

ADE shows it as a tiny thumbnail, the same kind as displayed in the library. Other random ebooks work fine with the same code and image.

 

I converted with Calibre one such book from EPUB 2 to 3 and reproduced the problem. Any idea what's going on? The code seems the same.

    This has something to do with the navigation file. As soon as I remove "properties="nav"" from

    <item id="nav" href="nav.xhtml" media-type="application/xhtml+xml" properties="nav"/>

    it shows the cover in the correct size but then of course without the TOC in the navigation pane.
