Graphics editors have several features for editing images, including dithering, color correction, cropping, selection, scaling, and layering. Dithering creates the illusion of more colors by changing dot patterns. Color correction adjusts colors to appear more realistic. Cropping removes outer parts of images. Selection isolates parts of images for editing. Scaling resizes images, which can distort pixels. Layering separates image elements on different layers that can be edited and turned on/off.
