How to use graphics.h in latest IDE's & Editors 2018
Just Follow the Steps for CODE::BLOCKS :-
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. Oct 25, 2011 Unfortunately, graphics.h is a Borland specific library and cannot be used with Dev-C. Fortunately, a benevolent soul by the name of Michael Main has modified a BGI emulation library for Windows applications to be used under MinGW (and therefore Dev-C.
- Clone the files from this repository. And download the Code::Blocks.
- Now copy the graphics.h & winbgim.h header files in
C:Program FilesCodeBlocksMinGWinclude
directory. - Now copy the libbgi.a library file in
C:Program FilesCodeBlocksMinGWlib
directory.
Note:
It may possible that your codeblocks installation is in another folder like Program Files(x86) by default codeblocks is installed in this directory. So find your path accordingly.- Now open your codeblocks and go to
Settings > Compiler Settings > Linker Settings
. Click onAdd
to link libraries and browse your libbgi.a library file; should be likeC:Program FilesCodeBlocksMinGWliblibbgi.a
. - In Linker Settings paste these linkers in Other linker options.
- Cheers
? ? Now run any graphics program. Remember that your program should be like name_of_file.cpp
. BecauseC
doesn't support sstream.
For Dev C++ you have to do the same upto Linker step. You need to add linkers with the project, just paste the linkers in
Project Options > Parameters > Linkers
. Or You can do it every project by pasting it in Tools > Compiler Options > General > in second textbox
Just Follow the Steps for Atom :-
- Clone the files from this repository. And download the Atom.
- Download the GCC compiler MinGW. And install it. Mark all options for installation.
- Set the path for the compiler. Go to
Control Panel > System > Advanced System Settings > Environment Variables > Path > Edit > New > paste C:MinGWbin
- Now open the Atom and install a package
gpp-compiler
from press (ctrl + comma) it'll open settings > Install. - After that paste those linkers, go to
Open settings > Packages > Settings of gpp-compiler package > C++ Compiler Options
. - Done! Create new file and press f5 to run the program.
- First Download the suitable binary file, according to your Linux OSThe current release of SDL_bgi is 2.2.3. To compile it from sources, you will need a compiler (gcc or clang are fine), make, and SDL2. On Debian and Ubuntu-like distributions, you will need the package 'libsdl2-dev' and its dependencies.
Building has been tested on GNU/Linux Mint 18.*, Fedora 26, Windows (MSYS2 + mingw-w64, Code::Blocks, Dev-C++ ), and Mac OS X Yosemite.
- Sources: SDL_bgi-2.2.3.tar.gz
- Source RPM package: SDL_bgi-2.2.3-1.src.rpm
- 64 bit binary RPM package (Fedora): SDL_bgi-2.2.3-1.x86_64.rpm
- 64 bit binary DEB package, for Debian-like Linux distributions: sdl_bgi_2.2.3-1_amd64.deb
- binaries for Windows (MSYS2 + mingw-w64, CodeBlocks, Dev-C++):
SDL_bgi-2.2.3-win.zip - Previous versions sources:
SDL_bgi-2.2.2.tar.gz
SDL_bgi-1.0.1.tar.gz
- To compile a program using SDL_bgi, make sure that it includes the 'graphics.h' header file. Then:
gcc -o program program.c -lSDL_bgi -lSDL2
- If you want to integrate this with your favourite editors the simply add linker.
-lSDL_bgi
-lSDL2
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. First graphics program (Draw a line)
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 toDETECT
, theninitgraph
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
Writing C++ In Xcode
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.
Constant | Value | Background? | Foreground? |
---|---|---|---|
BLACK | 0 | Yes | Yes |
BLUE | 1 | Yes | Yes |
GREEN | 2 | Yes | Yes |
CYAN | 3 | Yes | Yes |
RED | 4 | Yes | Yes |
MAGENTA | 5 | Yes | Yes |
BROWN | 6 | Yes | Yes |
LIGHTGRAY | 7 | Yes | Yes |
DARKGRAY | 8 | NO | Yes |
LIGHTBLUE | 9 | NO | Yes |
LIGHTGREEN | 10 | NO | Yes |
LIGHTCYAN | 11 | NO | Yes |
LIGHTRED | 12 | NO | Yes |
LIGHTMAGENTA | 13 | NO | Yes |
YELLOW | 14 | NO | Yes |
WHITE | 15 | NO | Yes |
BLINK | 128 | NO | * |
***** To display blinking characters in text mode, add BLINK to the foreground color. (Defined in
conio.h
