Those with an artist bent and bit of a creative side can go to town on their CentOS 7 desktop install.
For raster graphics we have the one and only GIMP.
For those who like to vectorize we have Inkscape.
Let us install them.
Open a terminal and type in the following command line then press ENTER on the keyboard.
sudo yum install gimp inkscape
At the prompt to accept, type y then ENTER on the keyboard.
Once install is complete. Close the terminal by clicking on the X at the top right corner of the window.
You can now run each of the applications by clicking on Activities at the top left corner of the screen, then click on the Show Applications icon shown below.
This will bring up the menu system. Navigate and click on the icon for one of the applications you have just installed.
Let your creative side run wild.
