Media Extension

The media extension provides the !media markdown command for adding images and videos. As used throughout MooseDocs content, the !media command can optionally create a numbered Float Extension by specifying the "id" setting. A caption may be include by using the "caption" setting.

The configuration options for the media extension are listed in Table 1.

Table 1: Configuration options for the media extension.

Images

The media extension supports including the standard html image extensions: png, gif, jpg, jpeg, and svg. Images are added using the !media command followed by the filename, as shown in Example 1. Table 2 includes the list of available settings for media command for images.

commentnote

The "style" setting may be used, as in the example below, to control the placement and size of the image.

Example 1: Example of the media command with an image.

!media media/inl_blue.png style=width:25%;float:right;margin-left:30px;

Videos

Locally stored or hosted videos can be displayed using the !media syntax. This works in the same fashion as for images, but also includes some extra settings as listed in Table 3.

Figure 1: "Big Buck Bunny" is an open-source animated short.

YouTube videos can also be displayed. The embedded youtube URL is simply provided as the media, this URL must contain 'www.youtube.com' and not end with an extension. Similar to locally stored or hosted videos, extra settings are provided as listed in Table 3.

Float Images/Videos

As is the case for many items within the MooseDocs system (i.e., Table Extension), it is possible to create numbered images that may be referenced, as shown in Example 2. The "id" and "caption" settings are available for both images and videos.

Example 2: Example image with caption and numbered prefix.

!media media/inl_blue.png
       id=inl-logo
       caption=The Idaho National Laboratory logo.
       style=width:50%;padding:20px;

Float Referencing

Referencing floats is possible using the !ref inline command, from both the same page and other pages:

Example 3: Example of referencing floats.

Float from the same page: [!ref](inl-logo)

Figure from different page: [!ref](graph.md#plotly-ext-config)

Table from different page: [!ref](table.md#table-floating)

Algorithm from different page: [!ref](algorithm.md#bk)

Float from the same page: Figure 3

Figure from different page: Graph Extension, Table 1

Table from different page: Table Extension, Table 1

Algorithm from different page: Algorithm Extension, Algorithm 1
