This is SDL_bgi, a graphics library written in C and based on SDL2.
SDL_bgi provides graphics primitives, and is much easier to use than
plain SDL2. It should be especially useful for beginners, i.e. in
introductory programming courses. I wrote SDL_bgi because I wanted a
simple to use but fast graphics library for my experiments with
fractals and cellular automata, using the BGI syntax I'm used to.
SDL_bgi is nearly fully compatible with BGI (graphics.h), the
Borland Graphics Interface that was the 'de facto' standard in PC
graphics back in DOS days. For instance, it compiles and runs the
original bgidemo.c almost perfectly. SDL_bgi also attempts to be
compatibile with another BGI clone, WinBGIm (see links below). One of
the aims of SDL_bgi is the preservation of old software written for
BGI.
SDL_bgi is pretty fast and very easy to use, and it also provides
extensions for ARGB colours, mouse support, and multiple windows.
Native SDL2 functions can be used alongside SDL_bgi functions.
SDL_bgi can be used by C++ programs, too.
SDL_bgi should compile on any platform supported by SDL2; it has
been tested in GNU/Linux, MS Windows (MSYS2 + Mingw-w64, CodeBlocks,
Dev-C++), Mac OS X Yosemite, and Raspberry Pi. A few example programs
are provided in the test/ directory.
If you don't need BGI compatibility, I suggest that you check out
SDL_gfx, a graphics library that is more complete and more powerful
than SDL_bgi.
