<!--
|
||||
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"/>
|
||||
|
||||
Define arguments for the memory, map, area, and disk resources with
|
||||
SI prefixes (.e.g 100MB). In addition, 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).
