Configure ImageMagick policies.

Domains include system, delegate, coder, filter, path, or resource.

Rights include none, read, write, and execute. Use | to combine them,
for example: "read | write" to permit read from, or write to, a path.

Use a glob expression as a pattern.

Suppose we do not want users to process MPEG video images:

<policy domain="delegate" rights="none" pattern="mpeg:decode" />

Here we do not want users reading images from HTTP:

<policy domain="coder" rights="none" pattern="HTTP" />

Lets prevent users from executing any image filters:

<policy domain="filter" rights="none" pattern="*" />

The /repository file system is restricted to read only. We use a glob
expression to match all paths that start with /repository:

<policy domain="path" rights="read" pattern="/repository/*" />

Any large image is cached to disk rather than memory:

<policy domain="resource" name="area" value="1gb"/>
<policy domain="resource" name="thread" value="6"/>

-->
<policymap>
<!-- <policy domain="system" name="precision" value="6"/> -->
<!-- <policy domain="resource" name="temporary-path" value="/tmp"/> -->
<!-- <policy domain="resource" name="memory" value="2gb"/> -->
<!-- <policy domain="resource" name="map" value="4gb"/> -->
<!-- <policy domain="resource" name="area" value="1gb"/> -->
<!-- <policy domain="resource" name="disk" value="16eb"/> -->
<!-- <policy domain="resource" name="file" value="768"/> -->
<policy domain="resource" name="thread" value="6"/>
<!-- <policy domain="resource" name="throttle" value="0"/> -->
<!-- <policy domain="resource" name="time" value="3600"/> -->
</policymap>
