- Download and unzip the following file:

zip file New version of Sept 26

• - During a lecture, launch the jar contained in it (you need to have at least the Java JRE installed, reccomended version is 8)
• - A tiny window will open in the uppr left corner of our screen, with a "Connect" button on it.
• - Click on the "Connect" button - it will change to a "Grab..."
• - Every time you click on "Grab", a copy of what you see projected on the screen in the classroom will be copied in your clipboard
• - Just do a "Paste" in any application (Word processor, drawing program, presentation program, etc) the content of the clipboard (i.e. a copy of the screen you just grabbed) will be included in your document.

NOTES
Make sure you have a version of Java which includes JavaFX. E.g. Java 11 does not, Java 8 does.
If your default java is Java8, then double clicking on your jar is enough to launch the program.

if not, the simplest thing to do is to

• Install Java JRE vs. 8
• if you have other versions of Java installed, you need to set a shortcut to teh bin directory of the java 8 distribution you installed, e.g. in bash you do export java8=/your/path/to/java8-home/bin

If you have an incompatible version of Java, and you installed Java8 as above described, then you have to open a terminal and:

• cd in the directory containing the jar
• launch the application from terminal giving the command java8 -jar _LodeScreenGrabber.jar

On some versions of Linux, it might be necessary to make sure the jar is executable. If that is the case, go to the directory where it is contained, and do a

• sudo chmod a+x _LodeScreenGrabber.jar

On Windows,  if double clicking your jar does not work, you can launch from cmd, or add java to your PATH (like in PATH=%PATH%;C:Program FilesJavajre8bin or wherever your java is installed)
