The Measurements and Scaling tool enable you to specify the dimensions (height and width values) and the distance or area of an object (image or contents within an image). This tool also enables you to view a specific screen area via image scaling.
To use the Image Dimensions feature in the Measurement and Scaling tool:
Click the Measure/Scale tool on the toolbar. This opens the Measurement and Scaling tool. This tool is split into three different functions. These functions are image dimensions, distance/area and image scaling. However, you must use the image dimensions function before you can use distance/area and image scaling functions. Use image dimensions to define the width and height of the viewable image.
Click the Adjust Width box and enter a numeric value next to the Width box.
You can also use the measurement bar to adjust the width and height of the image.
After you enter a numeric value for width, do the same thing for height.
To change the type of measurement used for the image, click on the pull-down box next to the word Metric. This gives you all the measurement choices available ( feet, inches, meters, and centimeters) by which to view the active image.
You may also click Cancel at any time while using the Measurement and Scaling tool. This will clear the active image of any measurement bars, or distance and area icons that may be on the image.
The Distance/Area option is helpful if you would like to find the distance and/or area of the object, or of parts of the object, in reference to the measurements given in the image dimension function.
Use Image Scaling to compare two or more images to each other in relative size in the viewable screen area (as defined by width and height in Measurement and Scaling ) or Image Scaling can show the actual size of an image in reference to the dimensions given in the Measurement and Scaling Tool..
Once you are done using the Measurement and Scaling functions, you may close or exit by clicking on the small circle in the top right hand corner of the window.
If you open the Measurement and Scaling function while the active image is still in the Image Workspace, then your measurements will still be available for you to use. If you close the image and return to the Group Workspace, then re-open the image again in the Image Workspace, your changes will not be saved (unless they are automatically entered because that particular image has pre-defined measurements in its data).
However, if you leave the Image Workspace using the Return to Group Window arrow on the tool, without closing the active window and then return back to the Image Workspace with a new image, the original dimensions on all the images will not be altered.
