Each image type is described as follows:
Line art
LineArt presents the image in black and white only and there are
no intermediate shades of gray in between. That means each
pixel of the image is 100% black or 100% white. LineArt is the
best choice of image type if you want to scan text, pen or ink
drawing. Since only 1-bit of black or white information is
required for each pixel*, the disk space required for saving
lineArt image is only about 1/24 of that required to save 24-bit
true color images.
