== Description ==
Command The <code>\externalfigure</code> command is used to include an external figure/movie inside ConTeXt. Includes both local files or remote files hosted on HTTP servers.  The simplest way to insert an image is to use: <context source="yes" mode="mkiv">\externalfigure[cow.pdf]</context> This command places the PDF image <code>cow.pdf</code> in a<code>\vbox</code>; the width and height of the image are equal to the natural dimensions of the image. To set the width of the image to a specific size, say <code>1cm</code>, use:<context source="yes" mode="mkiv" text="which gives">\externalfigure[cow.pdf][width=1cm]</context> Similarly, to set the height of the image to a specific size, say <code>2cm</code>, use:<context source="yes" mode="mkiv" text="which gives">\externalfigure[cow.pdf][height=2cm]</context> If only the <code>width</code> or <code>height</code> of the image is specified, the other dimension is scaled appropriately to keep the aspect ratio. To include a specific page, say page 5, of a multi-page PDF file, use:<texcode>\externalfigure[filename.pdf][page=5]</texcode> These four variations cover 90% of the use cases. 
=== How the filetype is determined ===
* '''auto''': When the file extension is <code>.auto</code> or <code>method=auto</code> is used, ConTeXt reads the first few bytes of the file to determine the filetype. Such an auto-discovery is useful for remote images that do not have a file extension.
If the extension of the file is not specified, ConTeXt searches for all possible extensions in the order given below. (When  Historically, when postscript output was used, the order in which the file extensions were searched depended on the output format (PDF or PS). These daysWith recent releases of ConTeXt, PDF is the default output format, so for all practical purposes, the order in which the file extensions are searched is fixed).
=== Natively supported image formats ===
=== Supported movie formats ===
 
{{note| Inclusion of movie formats is broken in MkIV }}
The following movie formats are supported.
* '''[http://en.wikipedia.org/wiki/QuickTime QuickTime]''': File extension <code>.mov</code>.
* '''[https://en.wikipedia.org/wiki/Flash_Video Flash Video]''': File extension <code>.flv</code>
* '''[https://en.wikipedia.org/wiki/MPEG-4 MPEG 4]''': File extension <code>.mp4</code>
 
{{ note| Movie inclusion only works in Adobe Acrobat but does not work on Linux }}
=== Support for special TeX formats ===
* '''cld''': Typeset the [[CLD|ConTeXt Lua document]] using <code>context</code> and include the result as a PDF file.
 
== Command options ==
 
=== <code>interaction</code> ===
 
By default, the interactive elements of the included PDF file are discarded. To enable the interactive elements of the included PDF file, use
 
<texcode>\externalfigure[filename.pdf][interaction=yes]</texcode>
