Using the Measurement/Scaling Tools:
The ability to use numeric measurements depends upon defining these fields in the image catalog data. They are useful if you need to compute the distance between two points on an image or if you need to determine the area of a space. Scaling allows you to determine the actual size of an image or part of an image and it allows you to scale all of the other images in the Image Workspace relative to a specific selected image. When you click on the icon, numeric measurement fields that have been entered in the catalog data fields are shown. You can edit them or enter new values, change the unit of measurement and determine the measurements of portions of the viewed image.
| To measure: | |
| 1. Click on the Distance button and select one point on the image. | |
| 2. Set it by clicking the Set button. | |
| 3. Select another point on the image and set it the same way. Use the two points on the image to find out the distance between them on the object. | |
| To find area: | |
| 1. Click on the Area button and select two points on the image | |
| 2. Setting them by clicking on the Set button. | |
| 3. Drag the upper or lower corners to draw a rectangle | |
| 4. Determine the area of the bounding rectangle. The area will appear in the Distance/Area box. | |
| To find scale: | |
| 1. Click on Scale and scale the image or images to actual size. | |
