| Configure ImageMagick policies. | ||
| Domains include system, delegate, coder, filter, path, or resource. | ||
| Rights include none, read, write, execute and all. 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/*" /> | ||
| Lets prevent users from executing any image filters: | ||
| <policy domain="filter" rights="none" pattern="*" /> | ||
| Any large image is cached to disk rather than memory: | ||
| <policy domain="resource" name="area" value="1GP"/> | ||
| Define arguments for the memory, map, area, width, height 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). | ||
| Rules are processed in order. Here we want to restrict ImageMagick to only | ||
| read or write a small subset of proven web-safe image types: | ||
| <policy domain="delegate" rights="none" pattern="*" /> | ||
| <policy domain="filter" rights="none" pattern="*" /> | ||
| <policy domain="coder" rights="none" pattern="*" /> | ||
| <policy domain="coder" rights="read|write" pattern="{GIF,JPEG,PNG,WEBP}" /> | ||
