A. a two-dimensional grid is applied on the image and each tiny cell on the grid is converted into a pixel
B. a two-dimensional grid is applied on the image to apply dithering to the image
C. an infinite number of color shades and tones in an analog image is mapped to a finite set of discrete color values
D. the resulting digital image file is compressed to have a smaller file size
C. an infinite number of color shades and tones in an analog image is mapped to a finite set of discrete color values
