Erode Function Memory Limitation

[AndreaImage]

Hi

i'm using ImageMagick to perform the Erode function on a Image
i need to limit the memory used by the process

during erosion process, due to the memory consuption, i can't do anything else (just wait...)

i'm trying to set the policy.xml to use max the 75% of the resource (modifyng the policy.xml file)

but i need some help

my pc has 8Gb of Ram and an HD of 128Gb

Code: Select all

-<policymap>

<!-- <policy domain="resource" name="temporary-path" value="/tmp"/> -->
<!-- <policy domain="resource" name="memory" value="6GiB"/> -->
<!-- <policy domain="resource" name="map" value="6GiB"/> -->
<!-- <policy domain="resource" name="width" value="100MP"/> -->
<!-- <policy domain="resource" name="height" value="100MP"/> -->
<!-- <policy domain="resource" name="area" value="1GB"/> -->
<!-- <policy domain="resource" name="disk" value="16EB"/> -->
<!-- <policy domain="resource" name="file" value="768"/> -->
<!-- <policy domain="resource" name="thread" value="4"/> -->
<!-- <policy domain="resource" name="throttle" value="0"/> -->
<!-- <policy domain="resource" name="time" value="3600"/> -->
<!-- <policy domain="system" name="precision" value="6"/> -->


<policy value="passphrase" name="shared-secret" domain="cache"/>

</policymap>

Someone can suggest which parameter has to be modify?

Thanks

I suspect you should un-comment the "memory" and "map" lines, and make both 4GiB or whatever you want.

it is working

which is the difference between "map" and "memory"?

thanks again

I'm not sure. The architecture document http://www.imagemagick.org/script/architecture.php says:

memory: maximum amount of memory in bytes to allocate for the pixel cache from the heap.

map: maximum amount of memory map in bytes to allocate for the pixel cache.
