Francesco Martini

After installing this plugin, you will be able to upload various ebook formats as normal media files and to display them in your site using a shortcode.
Every ebook uploaded in your site will have an “ebook slug” (by default it will be the ebook name) that you can view and edit in the Edit Media page of the Admin Panel.
The full source code of the plugin is hosted on <a href="https://github.com/wrCisco/simple-ebook-viewer-for-wp" rel="nofollow ugc">GitHub</a>.
Supported formats 
At the moment, the plugin will let you upload and display the following file types, provided that they are DRM-free:
<ul>
<li>epub</li>
<li>mobi</li>
<li>azw</li>
<li>azw3</li>
<li>fb2</li>
<li>fbz</li>
<li>cbz</li>
</ul>
Usage 
Insert the shortcode <code>[simebv_viewer book="MY_EBOOK_SLUG_HERE"]</code> in any one of your posts.
Styling 
You can add css styles and classes for the viewer container by adding these attributes to the shortcode:
<ul>
<li><code>height</code></li>
<li><code>width</code></li>
<li><code>max-height</code></li>
<li><code>max-width</code></li>
<li><code>border</code></li>
<li><code>style</code></li>
<li><code>class</code></li>
</ul>
Height, width, max-height, max-width and border accept any valid CSS value for those property. 
Style and class accept any valid value for the respective HTML attributes.
Some examples:
<pre><code>[simebv_viewer book="MY_EBOOK_SLUG_HERE" style="height:30em;border:2px inset black"]

[simebv_viewer book="MY_EBOOK_SLUG_HERE" max-height="100vh" height="40em"]

[simebv_viewer book="MY_EBOOK_SLUG_HERE" class="my-container-class my-container-second-class"]
</code></pre>
Settings 
The users of your site will be able to set their preferences about the appearance of the ebook in the Viewer by opening the Viewer menu (the cog icon on the top right) and by selecting the appropriate entries.
The plugin sets some reasonable defaults for these preferences, but if you’re not happy with those defaults, you can change them by adding one or more of the following attributes to the shortcode, with the appropriate values:
<ul>
<li><code>layout</code>
<ul>
<li>accepted values: “paginated” or “scrolled” (default: paginated)</li>
</ul>
</li>
<li><code>max-pages</code>
<ul>
<li>accepted values: 1, 2, 3 or 4 (default: 2)</li>
</ul>
</li>
<li><code>default-font-size</code>
<ul>
<li>accepted values: “small“, “medium“, “large“, “x-large” (default: medium)</li>
</ul>
</li>
<li><code>page-margins</code>
<ul>
<li>accepted values: “small“, “medium“, “large” (default: medium)</li>
</ul>
</li>
<li><code>zoom</code>
<ul>
<li>accepted values: “fit-page“, “fit-width” or a number in the range 10 – 400 (default: fit-page)</li>
</ul>
</li>
<li><code>color-scheme</code>
<ul>
<li>accepted values: “auto“, “sepia“, “light“, “dark” (default: auto)</li>
</ul>
</li>
</ul>
Layout, max-pages, default-font-size and page-margins are only available for reflowable ebooks, while zoom is only available for fixed layout ones.
Max-pages is the maximum number of pages (in the “paginated” layout) that the user will be able to see in a single view (if there is enough screen space).
Color-scheme: “auto” means that the Viewer will adapt to the preferred color-scheme set by the user in their device or browser (light or dark).
For most ebooks these preferences should be enough, but sometimes there are ebooks with style rules that don’t play well with the styles set by the Viewer, so the users have also the option to apply some filters to the Viewer’s colors (with the menu entry “Color filter…”).
You can set the default values for these filters with the following shortcode’s attributes:
<ul>
<li><code>activate-color-filter</code>
<ul>
<li>accepted values: “true“, “false” (default: false)</li>
</ul>
</li>
<li><code>invert-color-filter</code>
<ul>
<li>accepted values: a number in the range 0 – 1 (default: 0)</li>
</ul>
</li>
<li><code>rotate-color-filter</code>
<ul>
<li>accepted values: a number in the range 0 – 360 (default: 0)</li>
</ul>
</li>
<li><code>bg-transparent-filter</code>
<ul>
<li>accepted values: “true“, “false” (default: true)</li>
</ul>
</li>
<li><code>bg-color-filter</code>
<ul>
<li>accepted values: a valid CSS hex color code (default: #FFFFFF)</li>
</ul>
</li>
</ul>
Set activate-color-filter to “true” is necessary to enable all the other filters, and set bg-transparent-filter to false is necessary to enable bg-color-filter.
Bg-transparent-filter and bg-color-filter are available for reflowable ebooks only.
Invert-color-filter inverts the lightness of the colors. With a value of 0 it has no effect, with a value of 1, the white will become black and the black will become white.
Rotate-color-filter rotates the hues of all the colors in the ebook, like in a <a href="https://developer.mozilla.org/en-US/docs/Glossary/Color_wheel" rel="nofollow ugc">Color Wheel</a> (so, no effect on black and white).
<h3>Warning</h3>
Ebooks can contain scripted content that might be executed on your webpage. The plugin does its best to forbid script execution from inside the loaded content, but it can’t guarantee 100% safety. Don’t display ebooks from untrusted sources and/or check your ebooks before uploading and displaying them. If you can, provide a strict Content Security Policy for your site.
