Installing and Starting GIMP
The program we’re going to use is the GNU Image Manipulation Program, known as GIMP for short. It’s a highly sophisticated tool, and it’s available for free download not just on Linux, but for Windows and Mac computers as well.
To install GIMP on your Raspberry Pi, enter the following at the shell:
sudo apt-get install gimp
If you experience any difficulties, consult Chapter 5 for advice on installing software.
After installation is complete, you can start GIMP from the Graphics category in your Programs menu in the desktop environment (see Chapter 4).
