NAME

clip - limit the upper and lower grey values of an images to a specified value  

SYNOPSIS

clip [low high [new_low_value new_high_value]]  

DESCRIPTION

Clip examines each pixel of an image and if the value is greater than ``high'' or less than ``low'' replaces it with the clip value (default), or with a specified value. This technique is useful when, for instance, trying to histogram equalize some background information - the foreground can be suppressed. low defaults to 0, high to 255, new_low_value to low, and new_high_value to high.
