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:
➊view the distribution of black and white pixels in the selection area
➋set the black and white threshold (see page 85)
➌set the color channel
➍set the black and white threshold to the value determined by the scanning software
