Maybe a dumb question, but here goes: So, my C++ application uses GDI calls to draw pretty simple lines, arc, etc. overlaid on images. I'd like to upgrade the look of those graphics -- maybe with something a bit more powerful than GDI that can maybe do anti-aliasing, or other things to make the overlaid lines and circles look better and cute. So, I see talk of GDI+. And I saw a post of a GDI+ example, and the calls look exactly like the calls that I have been referring to as "GDI" for years. So, my application is MS VC++ and using IDS VS2015. Its not .NET -- just C++ code, often quite close to C code actually. So my questions:
1) Do I have to do something (link something or load something) to get GDI+? Or is it just there, ready for me to start calling?
2) I believe I can call things in GDI+ from my non-.NET C++ code, correct?
3) Will I find some things in GDI+ that were not in GDI that will help me make my graphics (overlaid on images) look better, cuter?
4) Where do I find doc so I can look thru what is available in GDI+ ?
