El archivo de encabezado graphics.h contiene la función bar3d() que se utiliza para dibujar una barra rellena rectangular bidimensional. Se requieren las coordenadas de la esquina superior izquierda e inferior derecha de la barra para dibujar la barra.
Sintaxis:
void bar3d(int left, int top, int right,
int bottom, int depth, int topflag);
where,
left specifies the X-coordinate of top left corner,
top specifies the Y-coordinate of top left corner,
right specifies the X-coordinate of right bottom corner,
bottom specifies the Y-coordinate of right bottom corner,
depth specifies the depth of bar in pixels,
topflag determines whether a 3 dimensional top is put on
the bar or not ( if it is non-zero then it is put otherwise not ).
Ejemplo :
Input : left = 150, top = 250,
right = 190, bottom = 350,
depth = 20, topflag = 1
left = 220, top = 150,
right = 260, bottom = 350,
depth = 20, topflag = 0
left = 290, top = 200,
right = 330, bottom = 350,
depth = 20, topflag = 1
Output :
A continuación se muestra la implementación de la función bar3d():
// C Implementation for bar3d() function
#include <graphics.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;
// initgraph initializes the
// graphics system by loading a
// graphics driver from disk
initgraph(&gd, &gm, "");
// location of sides
int left, top, right, bottom;
// depth of the bar
int depth;
// top flag denotes top line.
int topflag;
// left, top, right, bottom,
// depth, topflag location's
bar3d(left = 150, top = 250,
right = 190, bottom = 350,
depth = 20, topflag = 1);
bar3d(left = 220, top = 150,
right = 260, bottom = 350,
depth = 20, topflag = 0);
bar3d(left = 290, top = 200,
right = 330, bottom = 350,
depth = 20, topflag = 1);
// y axis line
line(100, 50, 100, 350);
// x axis line
line(100, 350, 400, 350);
getch();
// closegraph function closes the
// graphics mode and deallocates
// all memory allocated by
// graphics system .
closegraph();
return 0;
