Tool Window - Measurement

Use the Measurement tool window when you want to measure images. Use the View > Tool Windows > Measurement command to have the tool window displayed.

Makeup of the tool window

The tool window is made up of several groups. Click on one of the areas in the tool window shown schematically above, to jump to the corresponding help topic.

Measuring on charts

Your software has its own chart document. A chart can be saved, edited and also measured.

Use for example the Line Profile tool window to have the intensity profile along a line displayed on an image. Click the Export to Chart button in the tool window to export the line profile to a chart.

As soon as a chart has become active in the document group, the Measurement tool window changes its appearance. From then on, only the measurement functions that you can use for charts are available.

	Name of the button	Description
	Horizontal Line	Measure the distance between two interactively determined points in a chart.
	Multiple Horizontal Lines	Measure the horizontal distance between a reference line and one interactively determined point in a chart.

(1) The tool window's toolbar

The toolbar in the Measurement tool window contains all of the measurement functions and numerous important options you can use when you are interactively measuring.

Starting a measurement

Begin a measurement by clicking on the button with the measurement function you want. The button will appear clicked, thereby showing the active measurement function. You can recognize this status by the button's colored background.

Finishing the measurement mode

You will remain in this measurement mode until you explicitly switch it off. To do this, click on the measurement function's button again.

(2) Measurement display in the tool window

This tool window is at the same time the measurement display and contains all of the values that have been measured on the active image. It is also possible to have all of the measurements that have up till then been made on loaded images, displayed. To do so, clear the Tools > Options > Measurement > Results > Show measurement objects > Only of the active image check box.

Note: To enable you to see the list of the measurements properly, the Measurement tool window should be docked on the lower edge of the user interface. Additional information on positioning tool windows can be found here.

Sorting measurement values

By default the completed measurements will be sorted according to their measurement type in alphabetical order. The measurement type will be displayed in the Type column. You can, however, also change this order at any time. To do this, click in the measurement display, e.g. on the Type column header. The measurements will then be sorted in reverse alphabetical order. Clicking again returns the table to alphabetical order.

You can also change the sorting criterion and have the measurements sorted by every measurement parameter you wish, that is shown in the tool window, for example, by the measured area. To do so, click on the column header with this measurement parameter, in this example, Area.

Changing the displayed measurement values

You can change the order in which the measurement parameters are displayed in the Measurement tool window, however you want to. It is also possible to conceal measurement parameters that don't interest you and to have additional measurement parameters displayed. To do so, use the Select Measurements dialog box. A description of this dialog box can be found here.

Naming measurements

In the Measurement tool window, you can freely assign a name for every measurement, in the Name column. Double click with your left mouse button in the Name column. A flashing cursor will appear. Enter a name for your measurement.

Select the Show name check box, located in the Tools > Options > Measurement > Measurement Display dialog box to have the name of the measurement object displayed in the image or chart.
