since: 4.16

gsk_render_node_ref

Acquires a reference on the given GskRenderNode.

gsk_render_node_serialize

Serializes the node for later deserialization via gsk_render_node_deserialize(). No guarantees are made about the format used other than that the same version of GTK will be able to deserialize the result of a call to gsk_render_node_serialize() and gsk_render_node_deserialize() will correctly reject files it cannot open that were created with previous versions of GTK.

gsk_render_node_unref

Releases a reference on the given GskRenderNode.

gsk_render_node_write_to_file

This function is equivalent to calling gsk_render_node_serialize() followed by g_file_set_contents().
