11+ Configure ImageMagick policies.
12+
13+ Domains include system, delegate, coder, filter, path, or resource.
14+
15+ Rights include none, read, write, execute and all. Use | to combine them,
16+ for example: "read | write" to permit read from, or write to, a path.
17+
18+ Use a glob expression as a pattern.
19+
20+ Suppose we do not want users to process MPEG video images:
21+
22+ <policy domain="delegate" rights="none" pattern="mpeg:decode" />
23+
24+ Here we do not want users reading images from HTTP:
25+
26+ <policy domain="coder" rights="none" pattern="HTTP" />
27+
28+ The /repository file system is restricted to read only. We use a glob
29+ expression to match all paths that start with /repository:
30+
31+ <policy domain="path" rights="read" pattern="/repository/*" />
32+
33+ Lets prevent users from executing any image filters:
34+
35+ <policy domain="filter" rights="none" pattern="*" />
36+
37+ Any large image is cached to disk rather than memory:
38+
39+ <policy domain="resource" name="area" value="1GP"/>
40+
41+ Define arguments for the memory, map, area, width, height and disk resources
42+ with SI prefixes (.e.g 100MB). In addition, resource policies are maximums
43+ for each instance of ImageMagick (e.g. policy memory limit 1GB, -limit 2GB
44+ exceeds policy maximum so memory limit is 1GB).
45+
46+ Rules are processed in order. Here we want to restrict ImageMagick to only
47+ read or write a small subset of proven web-safe image types:
48+
49+ <policy domain="delegate" rights="none" pattern="*" />
50+ <policy domain="filter" rights="none" pattern="*" />
51+ <policy domain="coder" rights="none" pattern="*" />
52+ <policy domain="coder" rights="read|write" pattern="{GIF,JPEG,PNG,WEBP}" />
