NAME

Gimp::Data - Set and get state data.

SYNOPSIS

  use Gimp::Data;
  
  $Gimp::Data{'value1'} = "Hello";
  print $Gimp::Data{'value1'},", World!!\n";

DESCRIPTION

With this module, you can access plugin-specific (or global) data in Gimp, i.e. you can store and retrieve values that are stored in the main Gimp application.

An example would be to save parameter values in Gimp, so that on subsequent invocations of your plug-in, the user does not have to set all parameter values again (Gimp::Fu does this already).

%Gimp::Data

You can store and retrieve anything you like in this hash. It's contents will automatically be stored in Gimp, and can be accessed in later invocations of your plug-in. Be aware that other plug-ins store data in the same "hash", so better prefix your key with something unique, like your plug-in's name. As an example, the Gimp::Fu module uses "function_name/_fu_data" to store its data.

This module might use a persistant implementation, i.e. your data might survive a restart of the Gimp application, but you cannot count on this.

LIMITATIONS

You cannot store references, and you cannot (yet) iterate through the keys (with keys, values or each).
