/**
* pika_image_policy_color_profile:
* @image: The image.
* @interactive: Querying the user through a dialog is a possibility.
*
* Execute the color profile conversion policy.
*
* Process the image according to the color profile policy as set in
* Preferences.
* If PIKA is running as a GUI and interactive is TRUE, a dialog may be
* presented to the user depending on the policy. Otherwise, if the
* policy does not mandate the conversion to perform, the conversion to
* the preferred RGB or grayscale profile will happen, defaulting to
* built-in profiles if no preferred profiles were set in
* `Preferences`.
* This function should be used only if you want to follow user
* settings. If you intend to convert to a specific profile, call
* preferably pika_image_convert_color_profile(). And if you wish to
* leave whatever profile an image has, do not call any of these
* functions.
* Finally it is unnecessary to call this function in a format load
* procedure because this is called automatically by the core code when
* loading any image. You should only call this function explicitly
* when loading an image through a PDB call.
*
* Returns: TRUE on success.
*
* Since: 3.0
