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:
view the distribution of black and white pixels in the
selection area
set the black and white threshold (see page
92
)
set the color channel
set the black and white threshold to the value
determined by the scanning software
After you change settings in the
Black & White
Threshold
tool, the results of the new settings can
be seen in the preview area.
