4 Setup for MPGFX Library.
Follow these steps to start programming with MPGFX.
1 - Create directory called "MPGFX" or something you
like.
2 - Under this directory, create "source" and "include".
3 - From source disks, copy all the files with
cpp,cxx,asm extensions to the directory
mpgfx/source.
4 - From source disks, copy all the files with h
extensions to the directory mpgfx/include.
5 - Include all the gfx?.cpp ( or cxx ) modules and
appropriate low-level source files to your project
or makefile.
6 - You must define a macro before start compiling. See
below.
Macros for Compiler :
__FORBORLAND__ - Compiling for Borland.
__FORGCC__ - Compiling for GCC.
__FORVISUAL__ - Compiling for Visual.
__FORWATCOM__ - Compiling for Watcom.
Macros for Target Operating System :
__FORDOS__ - 16 Bit DOS.
__FORDOS4GW__ - 32 Bit DOS 4GW Extender.
__FORWIN16__ - 16 Bit Windows.
__FORWIN32__ - 32 Bit Windows. ( Windows 95, NT,
Win32s )
__FOROS2__ - 32 Bit OS/2.
__FORUNIX__ - Unix with X Wndows.
Macros for Tools or class library :
__FORMFC__ - Make it compatible to MFC class
library.
__FOROWL__ - Make it compatible to OWL class
library.
__FORMOTIF__ - Make it compatible to Motil
Toolkit.
* Exmaple - If you want to compile for Windows 95
using Watcom C/C++ with MFC library,
define :
__FORWATCOM__ __FORWIN32__ __FORMFC__
7 - Make mpgfx/include directory visible to your project.
8 - Include stdgfx.h and mpgfx.h file in your source
code.
5 Programming with MPGFX
5-1 Types
BYTE - Unsigned character. 1 Bytes
CHAR - Character. 1 Byte.
WORD - Unsigned Short. 2 Bytes.
SHORT - Short. 2 Bytes.
INT - Integer. ( 2/4 Bytes in 16/32 Bit Platform. )
UINT - Unisgned Integer. ( 2/4 Bytes in 16/32 Bit
Platform. )
LONG - Long Integer. 4 Bytes.
ULONG - Unsigned Long Integer. 4 Bytes.
DWORD - Unsigned Long Integer. 4 Bytes.
BOOLEAN - Boolean, (TRUE/FALSE) or (SUCCESS/FAILURE).
HDISPLAY - Displayable object. ( Source and destination of
graphic operations. )
5-2 Constants
TRUE - 1
FALSE - 0
SUCCESS - 1
FAILURE - 0
HVGA - Used as HDISPLAY of VGA(SVGA) memory. (Only used
in DOS)
M320x200x256 - Used for setting up VGA mode 320x200 by
256 Colors.
M640x400x256 - Used for setting up VESA mode 640x400 by
256 Colors.
M640x480x256 - Used for setting up VESA mode 640x480 by
256 Colors.
M800x600x256 - Used for setting up VESA mode 800x600 by
256 Colors.
M1024x768x256 - Used for setting up VESA mode 1024x768
by 256 Colors.
5-3 Global Object
Following objects are always visible and accessible to
high-level programmers.
GRAFIX Grafix - Graphics System.
SOUND Sound - Sound System.
INPUT Input - Input Handling System.
5-4 Setting up display.
Before any graphics operations, you must setup display by
calling
Grafix.SetDisplay ( INT GraphicsMode, VOID *Data );
GraphicsMode must one of the constant mentioned in 5-2 section. If you are programming for X Windows, Data must be a pointer to Display type in X Windows. ( Not HDISPLAY )
Just before your program terminate, you must call
Grafix.ResetDisplay ();
To reinitialize the graphics.
Example 1.
Following is the example of using MPGFX in DOS. It will switch to VGA 320x200 256 color mode and wait for you keyboard then reset graphics to normal and quit. Assuming you have finished setting up the steps of section 4.
