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.

to the mask editing functions.

the bottom limit line, and maximum is selected to edit the top limit 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.
