• Gray levels below the threshold are converted to black, resulting in a low-contrast, black-
and-white representation of the image.
• Gray levels equal to or above the threshold are converted to white, resulting in a high-

To use the Threshold feature, do either of the following:
• Enter a value in the Threshold edit box; or
• Drag the black triangle above the threshold edit box to the right or left. Moving it to the
right will increase the threshold value, resulting in a higher-contrast image. Moving it to
the left will lower the threshold value, resulting in a lower-contrast image.
