To create or edit a mask using line segments
The Measurement/Storage Module has a built-in Mask Editor for creating or
editing masks. It provides two editing tools: pixel editing and line drawing
editing. The line drawing editing tool can also be used to create a mask using
line segments.
To create the mask, you may want to first draw the mask on a piece of paper
and mark the coordinates of the end points of each straight line.

Line Drawing - Mark and Connect
Mark and Connect are used for drawing
straight lines in the mask. Their operation is explained later in this
paragraph.

Smooth Mask A running average of three pixels is used to smooth the
mask. It is especially useful for smoothing a mask created by Automask,
which may contain noise on the mask.
Each time Smooth Mask is selected, the entire mask is updated.
Selecting smoothing numerous times can alter the desired mask
pattern.
