Line Screen
Line Screen represents the number of lines per inch in a halftone image. Along
with Sampling (see below), the line screen is used to calculate the final scan
output resolution.
Sampling
Sampling indicates the number of dots per pixel in the final scanned image. The
Sampling value multiplied by the Line Screen value (see above) yields the dots
per inch (dpi) resolution of the final image. For example, a Sampling value of
2 with a Line Screen of 150 results in a 300 dpi image.
Using the Resolution Lock Tool
Clicking on the small lock icon next to the Line Screen field locks the scanner’s
resolution at the next highest native resolution. When locked, the scanner’s
native resolution is used; when unlocked, the final scan output resolution is
based on the values in the Line Screen and Sampling fields. To unlock the resolu-
tion, click on the lock icon again.
File Size
The File Size field is a static display of the amount of disk space the final scan
requires. As you adjust other scanning parameters, the value in this field changes.
Width and Height
You can select the specific width or height for your final image in these fields.
However, based on the cropped area, they are proportionate to each other. Any
change in the Width value proportionally changes Height and vice versa.
