C Graphics

Introduction to Turboc2 Graphics:

      Graphics in C Programming: Graphics are visual presentations on screen, paper, canvas etc.  The word Graphics came from Greek the word Graphicos. Graphics word is derived from the word Graph. Graph has Horizontal and Vertical directions. The Horizontal direction is also called as X-axis and the Vertical direction is called as Y-axis.
      Every digital screen has both X-direction and Y-direction. So the output of every digital device is called as Graphics. For example, an image generated by a digital camera is called Graphics.
      We must switch the Text mode to Graphics mode while we are writing Graphic Programs. The function initgraph() is responsible for switching the mode from Text to Graphics. DETECT is a macro defined in graphics.h. By using this macro the initgraph() to automatically determine which Graphic Driver to load inorder to switch to the highest resolution graphics mode.

                          Syntax: initgraph(int *graphicdriver,int *graphicmode,char *pathtodriver);

                 Here *graphicdriver, specifies Graphic Driver to be used. *graphicmode, specifies the initial Graphics Mode. *pathtodriver, specifies the directory path where initgraph() looks for graphics drivers.
       Once the driver has been loaded, initgraph() sets up the numeric values to the graphics mode.
