The Cairo drawing model relies on a three layer model. Any drawing process takes place in three steps: First a mask is created, which includes one or more vector primitives or forms, i. Then source must be defined, which may be a color, a color gradient, a bitmap or some vector graphics, and from the painted parts of this source a die cut is made with the help of the above defined mask. Finally the result is transferred to the destination or surface, which is provided by the back-end for the output. This constitutes a fundamentally different approach from Scalable Vector Graphics , which directly specifies the color of shapes with Cascading Style Sheets.

There is another function outtext that displayes a text in the current position. Current position is the place where last drawing is ended. These functions are declared as follows:. End angle in degrees. Refer this figure for clear idea: For the details of current color, fill color and fill patterns, refer the sections Lines and Colors.

Another basic shape that we come across is a rectangle. To draw a border, use rectangle with the coordinates of outline, to draw a square use rectangle with same height and width.

To use these functions, store coordinates of the shape in an array and pass the address of array as an argument to the function. By looking at the output of the previous program, you can understand what drawpoly is. Specifies number of points.

Graphics in C language (graphics.h header file functions and examples)

Points to a sequence of numpoints x 2 integers. Each pair of integers gives the x and y coordinates of a point on the polygon. Let us study more about shapes latter. Here is some idea about colors.

Graphics programming in C

There are 16 colors declared in graphics. To use these colors, use functions setcolor , setbkcolor and setfillstyle. If we use setcolor RED ; and draw any shape, line or text after that, the drawing will be in red color.

You can either use color as defined above or number like setcolor 4 ;. Setfillstyle sets fill pattern and fill colors. These function declarations are as follows. Names Value Means Fill With Here is an example program with colors, pixels, bar, cleardevice etc. We have a function random no , it returns a random number between 0 an no.

The effect is by drawing random radius, random color circles with same center and random pixels. So, the loop will continue until a key is pressed. In the next part of the article, Ranjith K. Read Part II. Tell us about this article: This is the first article of this tutorial. We are planning to expand it. To continue with, We need your suggestions. Tell us which part of the article need to be explained more, how can the article be elaborated more and how did you feel the article.

Click here to post a feed back or e-mail me: In GUI's like Windows, mouse is very important for user interaction. But in DOS, mouse will come in to picture only in some of the programs. If you are writing DOS games or graphics programs, you can add mouse functionality to your code.

Here is how to do that.

If you are beginner to Turbo C graphics programming, read our introduction to Turbo C graphics. Mouse can be used in text mode as well as in graphics mode. Usually it is used in graphics mode. Hence we must first change over to graphics mode. In our program the function initgraph is responsible for switching the mode from text to graphics.

It requests initgraph to automatically determine which graphics driver to load in order to switch to the highest resolution graphics mode. The initgraph function takes three parameters, the graphics driver, the graphics mode and the path to the driver file. Once the driver has been loaded, initgraph sets up the numeric values of the graphics mode chosen in the variables gd and gm respectively. Here we are assuming that the driver files are in the directory 'c: Hence the path passed to initgraph is 'c: The various mouse functions can be accessed by setting up the AX register with different values service number and issuing interrupt number When this function is called in main it displays the mouse pointer.

The position of the pointer can be changed by using the mouse.

Cairo (graphics)

When this function is called in main it hides the mouse pointer. This function is useful while drawing figures, first the mouse pointer is kept hidden, then the figure is been drawn and again the mouse pointer is been called. This function returns the position of the mouse pointer. It contains three parameters,they are xpos,ypos,click.

Click is the integer variable which returns the values 1,2,3 corresponding to the button pressed on the mouse and 0 for buttons being not pressed. If any key is pressed kbhit returns nonzero integer; if not it returns zero. This function sets the mouse pointer to specific position. CX is been loaded by x co-ordinate of the mouse pointer and DX is been loaded with the y co-ordinate of the mouse pointer.

Its sets the horizontal barrier for the pointer which restricts the mouse pointer to pass that limit. CX is been loaded with the minimum x co-ordinate and Dx is been loaded with the maximum x co-ordinate.

Its sets the vertical barrier for the pointer which restricts the mouse pointer to pass that limit. CX is been loaded with the minimum y co-ordinate and Dx is been loaded with the maximum y co- ordinate. Flag for inappropriate content. Related titles. Jump to Page. Search inside document.

To start the graphics system, you must first call initgraph.

To get details of different graphics modes and graphics drivers, view appendix. Basic Shapes and Colors: Now let us write a program to draw some basic shapes. These functions are declared as follows: The parameter pattern in setfillstyle is as follows: Read Part II Tell us about this article: Punam Patil.

Rendering involves a number of transformations, namely: rasterization, shading, illumination, and animation of the image. Following programs have been developed in Turbo C. Computer graphics play an important role in computer these are basically picture and movie created by using computer.

Display Systems Obviously it is important that graphics programs be able to draw more complex geometric forms from simple circles to complex surfaces in three dimensions. Using several tasks that engage the user in different ways as examples, this tutorial outlines principles for using color effectively in computer graphics. A Computer Science portal for geeks.

This is a video on computer graphics Although computer graphics is a vast field that encompasses almost any graphical aspect, we are mainly interested in the generation of images of 3-dimensional scenes.

It's difficult to tell what is being asked here. The best-selling book on computer graphics is now available in this C-language version. Another way to application program producing the graphics may run on a machine other than the one on which the graphics are displayed.

Computer graphics remains one of the most existing and rapidly growing computer fields. Define Computer Graphics. One is 3D animation. The server part of OpenGL, which runs on the workstation where the graphics are displayed, can access whatever physical graphics device or frame buffer is available on that machine.
