Drawing Circle in Graphics Mode - Graphics Programs

Drawing Circle in Graphics Mode.

⦁ Computer graphics is an art of drawing pictures, lines, charts, etc using computers with the help of programming. Computer is made up of number of pixels.

⦁ In this program we first initialize graphics mode, by passing graphics driver(DETECT), default graphics mode and specifies the directory path where initgraph looks for graphics drivers (* BGI).

⦁ Setting graphics driver as DETECT, means instructing the compiler to auto detect graphics driver.

⦁ Graphics functions used in this program are:

1. initgraph - It initializes the graphics system by loading the passed graphics driver then changing the system into graphics mode.

2. getmaxx - It returns the maximum X coordinate in current graphics mode and driver.

3. getmaxy - It returns the maximum Y coordinate i current graphics mode and driver.

4. outtextxy - It displays a string at a particular point(x,y) on screen.

5. circle - It draws a circle with radius r and center at(x,y).

6. closegraph - It unloads the graphics drivers and sets the screen back to text mode.

#include<stdio.h>
#include<graphics.h>
#include<conio.h>
int main( )
{
   int gd = DETECT,gm;
   int x, y, radius = 60;
   initgraph(&gd, &gm, "c:\\tc\\bgi");
   x = getmaxx( )/2;
   y = getmaxy( )/2;
   outtextxy(x-200,100,"CIRCLE using Graphics in C");
   circle(x,y,radius);
   getch( );
   closegraph( );
   return 0;
}
