12 | Configure ImageMagick policies.
|
13 |
|
14 | Domains include system, delegate, coder, filter, path, or resource.
|
15 |
|
16 | Rights include none, read, write, and execute. Use | to combine them,
|
17 | for example: "read | write" to permit read from, or write to, a path.
|
18 |
|
19 | Use a glob expression as a pattern.
|
20 |
|
21 | Suppose we do not want users to process MPEG video images:
|
22 |
|
23 | <policy domain="delegate" rights="none" pattern="mpeg:decode" />
|
24 |
|
25 | Here we do not want users reading images from HTTP:
|
26 |
|
27 | <policy domain="coder" rights="none" pattern="HTTP" />
|
28 |
|
29 | Lets prevent users from executing any image filters:
|
30 |
|
31 | <policy domain="filter" rights="none" pattern="*" />
|
32 |
|
33 | The /repository file system is restricted to read only. We use a glob
|
34 | expression to match all paths that start with /repository:
|
35 |
|
36 | <policy domain="path" rights="read" pattern="/repository/*" />
|
37 |
|
38 | Any large image is cached to disk rather than memory:
|
39 |
|
40 | <policy domain="resource" name="area" value="1GB"/>
|
41 |
|
42 | Define arguments for the memory, map, area, and disk resources with
|
43 | SI prefixes (.e.g 100MB). In addition, resource policies are maximums for
|
44 | each instance of ImageMagick (e.g. policy memory limit 1GB, -limit 2GB
|
45 | exceeds policy maximum so memory limit is 1GB).
