This function does not process image pixels.
The value that you set for hIGear determines whether the option settings will be retrieved from a specific image or a global setting for all new HIGEAR images. If you set hIGear to a specific image, the settings for that image will be returned. If you set hIGear to NULL, global settings for all new HIGEAR images will be returned.
