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). |
