Cannot set the Resource Type for this image

Error message

Cannot set the Resource Type for this image

What it means

Thrown by Imagick::setResourceLimit when the $type argument falls outside the valid Imagick resource-type constant range 0–6 (undefined/area/disk/file/map/memory/thread). The method proxies straight to ImagickNative::setResourceLimit, and rather than letting the native call fail it pre-validates the integer: a $type outside 0..6 means the caller passed an invented or wrong constant, so the guard rejects it with this sentinel error.

Solutions

1. Pass one of the Imagick::RESOURCETYPE_* constants (values 0-6)
2. Check that the constant you referenced actually exists in your Imagick version
