Black & White Threshold tool
The Black & White Threshold tool lets you change
the dividing point for black and white pixels in an
image that uses the
Black & White Bitmap (raster)
output type. All pixels below the threshold will be
output as black and all pixels above the threshold
will be output as white.
After you have drawn a selection area, use this
tool to:
➊
view the distribution of black and white pixels
in the selection area
➋
set the black and white threshold (see page 85)
➌
set the color channel
➍
set the black and white threshold to the value
determined by the scanning software
