Methods:

• public void cl_disable ()
  Disable OpenCL
• public bool cl_init () throws Error
  Initialize and enable OpenCL, calling this function again will re-enable OpenCL if it has been disabled.
• public bool cl_is_accelerated ()
  Check if OpenCL is enabled.
• public unowned Config config ()
  Returns a GeglConfig object with properties that can be manipulated to control GEGLs behavior.
• public void create_chain (string ops, Node op_start, Node op_end, double time, int rel_dim, string path_root) throws Error
  Create a node chain from an unparsed commandline string.
• public void create_chain_argv (string ops, Node op_start, Node op_end, double time, int rel_dim, string path_root) throws Error
  Create a node chain from argv style list of op data.
• public void exit ()
  Call this function when you're done using GEGL.
• public Value? format (string format_name)
  Returns a value sutable to pass to the GeglBuffer constructor or any other property that expects a Babl format.
• public unowned string? format_get_name (Value format)
• public void get_version (out int major, out int minor, out int micro)
  This function fetches the version of the GEGL library being used by the running process.
• public void graph_dump_outputs (Node node)
  Dump the bounds and format of each node in the graph to stdout.
• public void graph_dump_request (Node node, Rectangle roi)
  Dump the region that will be rendered for each node to fulfill the request.
• public bool has_operation (string operation_type)
• public void init (ref unowned string[]? argv)
  Call this function before using any other GEGL functions.
• public bool is_main_thread ()
• public (unowned string)[] list_operations ()
• public void load_module_directory (string path)
  Load all gegl modules found in the given directory.
• public void reset_stats ()
  Resets the cumulative data gathered by the Stats object returned by stats ().
• public string serialize (Node start, Node end, string basepath, SerializeFlag serialize_flags)
• public unowned Stats stats ()
  Returns a GeglStats object with properties that can be read to monitor GEGL statistics.
