What exactly is a graphic context? When drawing with Core Graphic we get a reference to the context. When I look at the documentation it seems like it is an object or so that take care of the correct drawing whether it is for printing, device, pdf and so on.
Could anyone help me to understand what a context really is? I tried reading the documentation but I do not understand. Is it an object that contains information(meta-data) about a system or something?
Thanks in advance
