Download Graphics H For Dev C++ Windows 10

Graphics programming in 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.

  1. C++ Download Windows 10

1. First graphics program (Draw a line)

This download installs the Intel® Graphics Driver for 6th Gen on Windows 7. and Windows 8.1./10. 64-bit. This download installs the Intel® Graphics Driver for Baytrail and 3rd generation. This download installs the Radeon™ RX Vega M 18.12.2 Graphics Driver for 8th generation. Download free open source code for your projects! //declarations for Lafore's console graphics functions. #include windows.h //for Windows console functions.

2. Explanation of Code :

The first step in any graphics program is to include graphics.h header file. The graphics.h header file provides access to a simple graphics library that makes it possible to draw lines, rectangles, ovals, arcs, polygons, images, and strings on a graphical window.

The second step is initialize the graphics drivers on the computer using initgraph method of graphics.h library.

It initializes the graphics system by loading the passed graphics driver then changing the system into graphics mode. It also resets or initializes all graphics settings like color, palette, current position etc, to their default values. Below is the description of input parameters of initgraph function.

  • graphicsDriver : It is a pointer to an integer specifying the graphics driver to be used. It tells the compiler that what graphics driver to use or to automatically detect the drive. In all our programs we will use DETECT macro of graphics.h library that instruct compiler for auto detection of graphics driver.

  • graphicsMode : It is a pointer to an integer that specifies the graphics mode to be used. If *gdriver is set to DETECT, then initgraph sets *gmode to the highest resolution available for the detected driver.

  • driverDirectoryPath : It specifies the directory path where graphics driver files (BGI files) are located. If directory path is not provided, then it will search for driver files in current working directory directory. In all our sample graphics programs, you have to change path of BGI directory accordingly where you Turbo C++ compiler is installed.

We have declared variables so that we can keep track of starting and ending point.

No, We need to pass just 4 parameters to the line function.

line Function Draws Line From (x1,y1) to (x2,y2) .

Parameter Explanation

  • x1 - X Co-ordinate of First Point
  • y1 - Y Co-ordinate of First Point
  • x2 - X Co-ordinate of Second Point
  • y2 - Y Co-ordinate of Second Point

At the end of our graphics program, we have to unloads the graphics drivers and sets the screen back to text mode by calling closegraph function.

3. Colors in C Graphics Programming

There are 16 colors declared in graphics.h header file. We use colors to set the current drawing color, change the color of background, change the color of text, to color a closed shape etc (Foreground and Background Color). To specify a color, we can either use color constants like setcolor(RED), or their corresponding integer codes like setcolor(4). Below is the color code in increasing order.
