Hi, all

Does Anybody have a good idea how to implement "undo" and "redo" in Cairo application?
I can use pair of APIs, cairo_image_surface_get_data() and cairo_image_surface_create_for_data() to store and to restore of buffer but I have no idea this is a correct approach or not.

Please feel free to give me any advises and ideas.
