In line art mode, the method for determining how gray levels are converted to black and
white is through the Threshold adjustment control.
The threshold is the dividing line between black and white, with the value 128 (the
middle gray level) as the determining point.
• 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-
contrast, black-and-white representation of the image.
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.
