Error Submitting EPUB to Android Book Store. - Page 2

Just a reminder that OP said graphic novel/comic and for that fixed layout EPUB 3 is 100% the correct choice. Reflowable would be a very bad experience in that case.

You could also make high quality PNGs of the images and try Kindle Comic Converter (it can make EPUBs despite the name) if you're having trouble with CSPs output.

However since the OP mentioned creating an epub2 which does not support fixed layout. What he seems to be doing is trying to generate a full page image for each image. I would suggest using an svg wrapper for the images and dumping the viewport.

Code:

  <style type="text/css" title="override_css">
            @page {padding: 0; margin:0;}
            body { text-align: center; padding:0; margin: 0; }
        </style>
</head>

<body>
  <div>
    <svg version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" width="100%" height="100%" viewBox="0 0 1000 1500" preserveAspectRatio="xMidYMid meet"><image width="1000" height="1500" xlink:href="../Images/image000.jpeg"/></svg>
  </div>

Set the width and height to the correct values for the images and this should allow a maximum size image without having to play games.

Note that this snippet is set for a 1000x1500 image which will have a left/right border on an eInk 3x4 aspect ratio screen. A 1125x1500 image would fit the screen aspect ratio.

This got me close to a solution actually. I ran it through and it was accepted by Google, but now I have another problem where it will display two pages at once, shrinking the image down in portrait mode. I've blurred the contents of the book in the provided image(which shows it displaying two pages at once), but what I would like is that if only 1 full page was presented at a time. Is there any way to do that with KCC?

Thank you David, I'm not too familiar with where this would go. Would I put that in the navigation folder, the style.css, etc? If so, does it matter what bracket of code it goes in?

This would be a html file so under text. The code is self contained so no CSS stylesheet is needed. Each text file would look similar to the one below. The changes needed would be to ensure the name of the graphics file (in this sample, image.jpeg) is changed to the name of the image file for the page and the width/height are changed in the places needed.

I've attached a simple ePub 3 file so you can take a look at the setup.

Code:

<?xml version="1.0" encoding="utf-8"?>
<!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" xml:lang="en">
<head>
  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
  <title>Image Testing</title>
  <style type="text/css" title="override_css">
            @page {padding: 0pt; margin:0pt}
            body { text-align: center; padding:0pt; margin: 0pt; }
        </style>
</head>

<body>
  <div>
    <svg version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" width="100%" height="100%" viewBox="0 0 1000 1500" preserveAspectRatio="xMidYMid meet"><image width="1000" height="1500" xlink:href="../Images/image.jpeg"/></svg>
  </div>
</body>
</html>

Fixed layout is a very limiting factor. If I bought an eBook that was fixed layout, I'd want my money back right away.

Graphic novels are rarely reflowable, Jon. Please focus on the request rather than pushing your anti-fixed-layout agenda.
