getbkcolor() function in C
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; } |
