A graphics editor is a program for drawing pictures and editing existing images. Paint in Windows is the simplest example, while GIMP and Krita offer far more features. The program window contains a toolbox, a color palette and a canvas to draw on.
The main tools are these: the pencil and brush draw freehand lines, the line, rectangle and ellipse tools make ready-made shapes, the fill (bucket) paints a closed area in one color, and the eraser removes what is not needed. You can select part of the picture and then move, copy, rotate or enlarge it.
If you make a mistake, undo the last action with Ctrl + Z. When you create a new picture, you can set its size in pixels. Save the finished picture as .png or .jpg: .png suits simple drawings and .jpg suits photographs.
