# Pixel Set Parameters

A Pixel Set operator takes two parameters:

- Pixel Value: An integer grey value between 0-255.

  The grey value you choose depends on your vision application.

- Operation: A choice between two options:

  - SetCarePels: Set Care pixels in the output image to the value defined by Pixel Value and pass Don't Care pixels directly to the output image unchanged.
  - SetDontCarePels: Set Don't Care pixels in output input image to the value defined by Pixel Value and pass Care pixels directly to the output image unchanged.

By default, the operator considers all pixels in the input image as Care pixels. Depending on how you configure an input region and/or an image mask, the operator can classify certain input image pixels as Care pixels and others as Don't Care pixels before setting one or the other to a uniform grey value in the output image.

How the operator designates pixels as Care or Don't Care depends on the type of input region and/or image mask you use.
