Measurement
Types of measurement you can calculate, including position, length, angle, and area.
- Position Results
Position of the point that you selected on the image using an ROI tool from the toolbar.
- X Pos.—X-coordinate
- Y Pos.—Y-coordinate
- Lev.—Grayscale value of the pixel
- Length Results
Measurements associated with the ROI.
- Length—Length of the ROI in user-calibrated units.
- Start X—X-coordinate of the starting point of the ROI.
- Start Y—Y-coordinate of the starting point of the ROI.
- End X—X-coordinate of the ending point of the ROI.
- End Y—Y-coordinate of the ending point of the ROI.
- Mean—Mean of the grayscale values found in the ROI.
- StdDev—Standard deviation in the ROI.
- Min—Smallest grayscale value found in the ROI.
- Max—Largest grayscale value found in the ROI.
- Angle Results
- Angle—Angle between any two line segments on the image, measured in degrees, counterclockwise.
- Area Results
Measurements associated with the ROI.
- Area—Area of the ROI.
- Ratio—Ratio of the ROI area to the entire image area.
- X1—Top, left x-coordinate of the ROI bounding rectangle.
- Y1—Top, left y-coordinate of the ROI bounding rectangle.
- X2—Bottom, right x-coordinate of the ROI bounding rectangle.
- Y2—Bottom, right y-coordinate of the ROI bounding rectangle.
- Mean—Mean of all grayscale values found in the ROI.
- StdDev—Standard deviation of all grayscale values found in the ROI.
- Min—Smallest grayscale value found in the ROI.
- Max—Largest grayscale value found in the ROI.
