  C - GRAPHICS Dr.Thamba Meshach W HOD - CSE
• 2.
  GRAPHICS It refers toany visual representation of data. Example: drawings, photographs, line art, graphs, diagrams, numbers, symbols, geometric designs, maps, and engineering drawings.
• 3.
  WHAT IS C GRAPHICS? Graphics programmingin C used to • drawing various geometrical shapes(rectangle, circle eclipse etc.), • use of mathematical function in drawing curves, coloring an object with different colors and patterns and simple animation programs like jumping ball and moving cars.

  4 SYNTAX initgraph(int *gd, int*gm, char *driverDirectoryPath); The first parameter (gd) is a pointer to the graphics driver, which is set to DETECT to detect the graphics driver automatically. The second parameter (gm) is the graphics mode, which specifies the resolution and color depth of the screen. The last parameter is a string that can be used to pass additional arguments to the graphics driver.

  EXAMPLE: DRAW ALINE #include<graphics.h> #include<stdio.h> #include<conio.h> void main() { int gdriver = DETECT, gmode; int x1 = 200, y1 = 200; int x2 = 300, y2 = 300; clrscr(); initgraph(&gdriver, &gmode, "c:turboc3bgi"); line(x1, y1, x2, y2); getch(); closegraph(); }
