Threshold

Used to convert a grayscale image to a

bi-tonal image. The value ranges from 0 to

255. A low threshold value produces a

lighter image, and can be used to subdue

backgrounds and subtle, unneeded

information. A high threshold value produces

a darker image, and can be used to help pick

up faint images.

Adjust the threshold setting by dragging the

Threshold sliding bar to the left or right to

achieve the desired threshold setting.
