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"/>
Note, resource policies are maximums for each instance of ImageMagick (e.g.
policy memory limit 1GB, -limit 2GB exceeds policy maximum so memory limit
is 1GB).
