| + | |||
| + | ====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> | ||
