Borland Graphics Interface (BGI) for Windows

The following functions are mostly from the original Borland Graphics Interface for DOS programs. The BGI graphics functions may also be used with Windows programs created by the Borland 5.0 compiler, the free GNU C++ compiler, and possibly other compilers. Extra Windows functions are also available, described in www.cs.colorado.edu/~main/bgi/doc/bgi.html. These extra functions are indicated below by . Also, any of the functions that use colors can use RGB colors in addition to the 16-color BGI palette.
