noise or extra edges in the ROI, but under some circumstances it may ignore edges you wish to include. Also, if the
line in the image has gaps in it, this mode may produce lines that are shorter than you want.
• "Line, All Points" finds a line that explains all the edges as well as possible without ignoring anything. This setting
is the fastest, but it works poorly if there are any extra edges or noise within the ROI. This mode can be useful if the
line being examined is jagged, irregular, or curved.

Description Result
The (x,y) coordinates of the start, middle, and end of the line found. Click on any
of these results to see where they are in the image. By definition, the start point

will be on the end of the line that is closer to the left side of the R OI, when viewed
in the direction of the arrows.
Use these values with a Measure tool.

an edge. This result may be most useful when using the Search For "Line, All
Points" option.
The distance from the start point of the line to the end point.
Length
The angle between the x-axis and the vector from the start of the line to the end
of the line. This will be in the range from -180 to +180.
Angle
The average distance between the green edge points and the line found. Use this
value in a Test tool to determine whether a line is curved or irregular. This may
be most useful when using the Search For "Line, All Points" option.

7.3.7 Object Tool
The Object tool detects the edges of dark and bright segments in an ROI. The Object tool measures the widths of every
dark and light segment along the ROI. The Object tool calculates the midpoint for every object, and counts the total
number of objects. The midpoint can be used to measure distances and angles. Each object can have unique size limit,
or all objects may have the same size limit.
