Scanning Source
Two scanning sources are provided- flatbed as well
as transparency.
Line art presents the image in black and white only
and there are no intermediate shades of gray in
between.
In addition to the black and white display,
Halftone can present the gray shades of a scanned
image by varying the dot (pixel) sizes.
While taking up but a minimum storage space,
error diffusion gives good image texture and
excellent image details.
