 +===== bar3d =====

 +
 +====Syntax of bar3d ==== 
 + <code c>
 +#include <graphics.h>
 +void bar3d(int left, int top, int right, int bottom, int depth, int
 +topflag);
 +  </code>
 +
 +
 +==== Description of bar3d ==== 
 +<code c>
 +bar3d draws a three-dimensional rectangular bar, then fills it using the
 +current fill pattern and fill color. The three-dimensional outline of the
 +bar is drawn in the current line style and color. The bar's depth in
 +pixels is given by depth. The topflag parameter governs whether a three-
 +dimensional top is put on the bar. If topflag is nonzero, a top is put
 +on; otherwise, no top is put on the bar (making it possible to stack
 +several bars on top of one another). The upper left and lower right
 +corners of the rectangle are given by (left, top) and (right, bottom),
 +respectively.
 +To calculate a typical depth for bar3d, take 25% of the width of the bar,
 +like this:
 +   bar3d(left,top,right,bottom, (right-left)/4,1);
 +</code>
