[SDL] Using MSVC Bitmap Resource with SDL_Image

[James Buchwald]

No, it wouldn't necessarily require an external file. You're right - you can
load stuff that's buffered in memory. What you'll have to do is load your
bitmap resource as an HBITMAP using some sort of GDI method, then convert it
into a format that can be used by an SDL_RWops. I'm not sure quite how you
would go about doing that, but that's the basics of it.

One option you might want to consider instead is to use XPM images and the
SDL_image library. The XPM format is actually a C source file (meaning it
works in C++), and you can build it right into your program by including it
like a header file. In the header file is a large array of pixel data, and
it supports transparency, too. There's a method in the SDL_image library to
convert that structure into an SDL_Surface.

Good luck.
