El archivo de encabezado graphics.h contiene la función getbkcolor() que devuelve el color de fondo actual.
Sintaxis:
int getbkcolor();
Como getbkcolor() devuelve un valor entero correspondiente al color de fondo, a continuación se muestra la tabla de valores de color.
Tabla de colores:
COLOR INT VALUES ------------------------------- BLACK 0 BLUE 1 GREEN 2 CYAN 3 RED 4 MAGENTA 5 BROWN 6 LIGHTGRAY 7 DARKGRAY 8 LIGHTBLUE 9 LIGHTGREEN 10 LIGHTCYAN 11 LIGHTRED 12 LIGHTMAGENTA 13 YELLOW 14 WHITE 15
Cuando el color de fondo es negro:
// C Implementation for getbkcolor function
#include <graphics.h>
#include <stdio.h>
// driver code
int main()
{
// gm is Graphics mode which is
// a computer display mode that
// generates image using pixels.
// DETECT is a macro defined in
// "graphics.h" header file
int gd = DETECT, gm;
char arr[100];
// initgraph initializes the
// graphics system by loading a
// graphics driver from disk
initgraph(&gd, &gm, "");
// sprintf stands for “String print”.
// Instead of printing on console, it
// store output on char buffer which
// are specified in sprintf
sprintf(arr, "Current background color = %d",
getbkcolor());
// outtext function displays text
// at current position.
outtextxy(10, 10, arr);
getch();
// closegraph function closes the
// graphics mode and deallocates
// all memory allocated by
// graphics system .
closegraph();
return 0;
