Initializing Graphics


inigraph() initializes the graphics system.

To start the graphics system, u must call this function.

Syntax :

initgraph(int far &graphdriver,int far &graphmode,char far pathtodriver);

This function initializes the graphics system by loading a graphics driver from disk then putting the system into graphics mode.

It also resets all graphics settings(color,current position) to their defaults.

Note : '&' sign has to be placed before the first two arguments. As this is the address of location from which driver has to be loaded.

Arguments used :

graphdriver:

Integer that specifies the graphics driver to be used.

graphmode :

Integer that specifies the initial graphics mode.

If graphmode==DETECT then initgraph sets *graphmode to the highest resolution
available for the detected driver.

pathtodriver :

Specifies the directory path where initgraph looks for graphics driver(*.BGI) first.

Suppose you have TC folder in c drive that contains lib,bgi and other folders, then your
pathtodriver will be :

c:\\tc\\bgi

that is you set the path by typing :

name of drive where your turbo c is present//turbo c folder name//bgi

Example:


#include <graphics.h>
#include <conio.h>

void main()
{
int d,m;

d=DETECT;

initgraph(&d,&m,"c:\\tc\\bgi"); //notice that '&' is placed before the first two arguments

circle(100,100,20);

closegraph();
}
