I have used graphics.h in dev cpp. Though I can't remember the exact steps I used to include it, but I think the below answer is correct. Source: How to configure graphics.h in Dev-C > You can easily solve this problem, DEV-C do support gra. Graphics.h is used for drawing graphics in c language. You can draw the different shapes, graphs, or write your name using this library in c language. This library is pretty cool. But questions come in our mind that how to include graphics.h library in our CodeBlocks software and can start drawing amazing graphics.

The graphics.h is a header file in C programming that helps you to include methods related to graphics in your C Program. In addition to the graphics.h library in C programming, there are many libraries that offer functionalities to develop graphics programs in Linux. The libgraph library, to be frank, is an age-old library.

This page describes gfx, a simple graphics library for CSE 20211.This library is meant to be simple and easy to learn, so that beginningCSE students can get right into the interesting parts of programming.The gfx library only requires that the programmer understandhow to invoke basic C functions with scalar arguments.

It is more than enough to explore raster and vector graphics,create animations, draw fractal shapes, and write simple video games. It doesn't do everything that you might want a graphicslibrary to do. As you learn more about programming, more advancedlibraries that you might consider using are OpenGL for precise 3-D graphics, Qt for windowed applications, and SDL for video games.

This library runs on Linux machines using the X11 Window System. (You may be able to run it on a Mac, but it won't work on Windows.) So, you will have to go to the computer lab to work on this assignment.

Getting Started

Download the following files and put them in your lab directory:

gfx.c (the source file: read if you like, but don't change)

gfx.h (the header file: read if you like, but don't change)

example.c (an example program: go ahead and change this)

To compile a program that uses the gfx library, you need touse the following command, which compiles your program with gfx.cthen adds the X11 and math libraries. Flight1 gtn 750 crack. (X11 is short for the X Window System used on Unix based machines.)

On a Mac with XCode and the X Windows option installed, the following might work:Run the example program, and you should see a window pop up with a green triangle.

Line by Line Example

To give you the idea of how to use the library, we will point outthe important parts of example.c in detail. Then, belowyou can read about how the individual functions work.

Begin by including gfx.h, to make the library available to the program. Note that quotes rather than angle brackets are used in this statement. Quotes indicate the header file is in the current directory, rather than in some system-defined place.

To open a graphics window, call gfx_open once at the beginning of the program, giving the width and height of the window in pixels, and the title of the window on the screen:gfx_color sets the current drawing color to a pale green:Now, use the gfx_line function to draw a line from (100,100) to (200,100):Wait for the user to press a key (or button):If the key is the letter 'q', break out of the loop:That shows you enough to get started.There are a few more useful functions in the library,read the following section to see them all.

Function Reference

gfx_open creates a new graphics window on the screen.width is the width of the window in pixels.height is the height of the window in pixels.title is the name of the window in the title bar.gfx_line draws a line in the graphics window, using thecurrent color, from location x1,y1 to x2,y2gfx_color sets the current color for drawing, using the RGB color model, in which you mix red, green, and blue components in order to get the desired color. gfx_color takes three integers between 0 and 255, each representing red, green, and blue. The following are some example colors:

Red	Green	Blue	Color Name
255	0	0	Red
0	255	0	Green
0	0	255	Blue
255	255	0	Yellow
255	255	255	White
100	100	100	Gray
0	0	0	Black

gfx_clear clears the window to the current background color,which is black by default.gfx_clear_color changes the background color, usingthe same format as gfx_clear above. The new backgroundcolor takes effect the next time gfx_clear is called.gfx_wait waits until the user presses a key or mouse button.If the user has pressed a mouse button, the integer 1, 2, or 3 will be returned,indicating the button pressed. If the user has pressed a key, that characterwill be returned. To determine the mouse location at that time, call gfx_xpos and gfx_ypos.gfx_xpos() and gfx_ypos return the X and Y coordinates, respectively, of the mouse pointerwhen the last key or button was pressed.gfx_wait causes the program to wait until something is pressed,which can be inconvenient in a real-time program. To avoid this, callgfx_event_waiting, which returns true if an event (key or button press)has occurred, otherwise returns false immediately. If it returns true, thenyou can call gfx_wait to retrieve the event without waiting.

gfx_flush flushes all output to the graphics window.This forces all previous drawing commands to take effect.Output is normally flushed after a called to gfx_wait.If your program does not call gfx_wait then you needto call gfx_flush after drawing to the screen.

A header file is a file with extension .h which contains C function declarations and macro definitions to be shared between several source files. There are two types of header files: the files that the programmer writes and the files that comes with your compiler.

/serum-x64-download.html. You request to use a header file in your program by including it with the C preprocessing directive #include, like you have seen inclusion of stdio.h header file, which comes along with your compiler.

Including a header file is equal to copying the content of the header file but we do not do it because it will be error-prone and it is not a good idea to copy the content of a header file in the source files, especially if we have multiple source files in a program.

A simple practice in C or C++ programs is that we keep all the constants, macros, system wide global variables, and function prototypes in the header files and include that header file wherever it is required.

Include Syntax

Both the user and the system header files are included using the preprocessing directive #include. It has the following two forms −

This form is used for system header files. It searches for a file named 'file' in a standard list of system directories. You can prepend directories to this list with the -I option while compiling your source code.

This form is used for header files of your own program. It searches for a file named 'file' in the directory containing the current file. You can prepend directories to this list with the -I option while compiling your source code.

Include Operation

The #include directive works by directing the C preprocessor to scan the specified file as input before continuing with the rest of the current source file. The output from the preprocessor contains the output already generated, followed by the output resulting from the included file, followed by the output that comes from the text after the #include directive. For example, if you have a header file header.h as follows −

and a main program called program.c that uses the header file, like this −

the compiler will see the same token stream as it would if program.c read.

Once-Only Headers

If a header file happens to be included twice, the compiler will process its contents twice and it will result in an error. The standard way to prevent this is to enclose the entire real contents of the file in a conditional, like this −

This construct is commonly known as a wrapper #ifndef. When the header is included again, the conditional will be false, because HEADER_FILE is defined. The preprocessor will skip over the entire contents of the file, and the compiler will not see it twice.

Computed Includes

Graphics.h File For Code Blocks

Sometimes it is necessary to select one of the several different header files to be included into your program. For instance, they might specify configuration parameters to be used on different sorts of operating systems. You could do this with a series of conditionals as follows −

But as it grows, it becomes tedious, instead the preprocessor offers the ability to use a macro for the header name. This is called a computed include. Instead of writing a header name as the direct argument of #include, you simply put a macro name there −

SYSTEM_H will be expanded, and the preprocessor will look for system_1.h as if the #include had been written that way originally. SYSTEM_H could be defined by your Makefile with a -D option.
