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
