About Virtual Magnifying Glass

	Virtual Magnifying Glass is designed for visually-impaired and others who need to magnify a part of the screen. Unlike most similar programs it does not open a separate window for the magnification but instead puts a movable magnifying glass on screen.

	This software is the multiplatform version of Virtual Magnifying Glass. Any feedback you can give us about this software will be greatly appreciated and can greatly enhance the quality of the software. You can give us feedback on our source-forge page: http://sourceforge.net/projects/magnifier

Installation Guide for Windows

	Just follow the steps in the order they appear. If you need help installing, go to our website (http://sourceforge.net/projects/magnifier) and describe your problem.

1 - Download the .exe installation file to a known location.

2 – Execute the install software.

3 – Follow the instructions on the screen to install the software

Installation Guide for Linux and FreeBSD

	Just follow the steps in the order they appear. If you need help installing, go to our website (http://sourceforge.net/projects/magnifier) and describe your problem.

1 - Download the magnifier tar.bz2 package to a known location

2 – Open a terminal session and change to root by issuing the “su” command

3 - Go to the directory where the package was downloaded

4 – Uncompress the file with the command: “tar -jxvf package_name.tar.bz2” e enter the directory which is created with “cd magnifier”

5 – Run the install script: ./install.sh

6 – If you wish to create a link on the desktop just type:

ln -s /usr/share/magnifier/magnifier $HOME/Desktop/magnifier

In case you receive error messages, check if all the dependencies of the program are installed.

Note: There is also a uninstall script called uninstall.sh

Another Note: If your distribution doesn't use the standard directories for Install, please run magnifier once so it will create a .magnifier.conf file on your user directory (most times /home/usarname). Now edit that file and change the MyDirectory field to the correct location.

Important Note: In case you have problems executing the program, please run it from the command line so you can see any error messages.

Dependencies

	This are the most important dependencies of the software:

•	Gtk 2.6 or superior
•	libgdk_pixbuf2

	You can see a complete list of .so files needed by the software using the command:

	In case you cannot run the program and it displays a message saying it cannot find one of this libraries (you must run the program from the command line to see error messages), you need to download and install a package for the necessary library:

	On RPM-based distributions you can find packages here: http://rpm.pbone.net/

Using the Dynamic Mode
	The Dynamic Mode currently works under Windows 2000+. Unlike previous versions there is no longer the need to have DirectX installed or to have a special video card.
	To activate the dynamic mode open the magnifier, right-click it's tray icon, select “Dynamic Mode” and then activate the glass. While using the dynamic mode  the default magnifier keys won't work most of the time. We have, instead, special keys to move the glass while in Dynamic Mode. To exit the dynamic mode, right click the tray icon of the magnifier and quit it, or start a non-dynamic mode session.

	The following keys are available to use the glass with the dynamic mode:

Key	Command	
[Ctrl] + [Alt] + Up Arrow
[Ctrl] + [Alt] + W
[Ctrl] + [Alt] + 8	Moves the glass up	
[Ctrl] + [Alt] + Down Arrow
