The Measurement and Analysis tool used to measure and straighten images. On the toolbar there are some important icons:
In this image, the first icon is selected, which is the Region tool. The next icon is the line tool. Rather than drawing a region (box, or region of interest), this will draw a line on the image. The right-most icon will display the Measurement and Analysis tool window.
Region The four edit boxes contain the coordinates of the currently selection region (region of interest). The width, height and aspect ratio (A/R) of the region are also displayed.
Line When a line is drawn on the image, the length and logical length are calculated. In addition, the angle of the line and length in pixels are also displayed.
When a line is defined, you can click this button to straighten the image based on the angle of the line.
Click this button to change the color of the line.
Example
As an example, image that you know that 1 pixel in your image is equivalent to 2mm. You can set the measurement to 'mm' and the Logical length to 2.000. Then, as you draw a line on the image, you can see the measurement in mm. In the example below, the Length (pixels) is 75.0, and therefore our measurement is 150.00mm.
