Description

Queries a define value.
Tagged image format define. Similar to the get/setdefineValue() functions except that passing the flag value 'true' creates a value-less define with that format and key. Passing the flag value 'false' removes any existing matching definition. The method returns 'true' if a matching key exists, and 'false' if no matching key exists.
