5.3 SELECTING A PROPER IMAGE TYPE
Select image type through the mode from the scanner user
interface
for your own purpose.
Each image type is described as follows:
Line art (Black and White)
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.
