The header file graphics.h contains getbkcolor() function which returns the current background color.
Syntax :
int getbkcolor();
As getbkcolor() returns an integer value corresponding to the background color, so below is the table for Color values.
Colors Table :
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
When the background color is black:
// 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;
} |
Output :
When the background color is other than black:
// 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, "" );
// set background color as RED
setbkcolor(RED);
// 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;
