Borland Graphics Interface (BGI)

Using BGI with Windows

The BGI graphics functions may also be used with Windows programs created by the Borland 5.0 compiler or the free GNU C++ compiler. These extra functions are described in www.cs.colorado.edu/~main/bgi/doc/bgi.html. In this listing, the extra functions are indicated by . Also, any of the functions that use colors can use RGB colors in addition to the 16-color BGI palette.
