| This plugin embeds Viewer.JS into WordPress. This is a combination of WebODF and PDF.js. See www.viewerjs.org for more details. | ||
|
|
||
| == Usage == | ||
|
|
||
| Navigate to a Document file (ODF or PDF) in your WP blog's media library and press the button "Insert with Viewer.JS". | ||
| Alternatively you can manually insert the WordPress shortcode `[viewerjs /path-to-some-file.pdf]` to embed | ||
| any `*.pdf`, `*.odt`, `*.odp`, or `*.ods` documents at that location. | ||
|
|
||
| The plugin also provides a settings panel for adjusting the width and height of the embeded element (iframe). | ||
|
|
||
| == Installation == | ||
|
|
||
| 1. Upload the whole `viewer.js-plugin` directory and content to the `/wp-content/plugins/` directory | ||
| 2. Activate the plugin through the 'Plugins' menu in WordPress | ||
|
|
||
| (or do the automatic stuff from the /wp-admin/...) | ||
