Object label

Selecting measurement parameters for the label

In the Measurement list, select a measurement parameter. The Measurement list contains only the measurement parameters that are shown for the active image in the Object Measurements results view of the Count and Measure Results tool window. Should you want to display another measurement parameter in the image, you will have to add it to the existing measurement parameters in the Select Object Measurements dialog box.

The measurement objects will then be labeled in the image with the corresponding measurement values. With an area measurement the labeling will be 38.1, for example, when the measurement object's area is 38.1 µm². You can set whether the unit of the measurement value is to be specified, or not.

From the Measurement list, select the None option, if the measurement object is not to be labeled. In this case the objects will be detected automatically, and displayed in the corresponding class color in the image. You will find this entry right at the top of the list.

Selecting the color of the label

Click the arrow next to the Color list to open a color table, and to choose a color for the labeling. The labeling will be displayed in the color you have assigned it.

If you want your software to automatically choose a suitable color, select the Automatic option.

Restricting labelling to a particular object size

When you have a large number of very small objects, you can define a minimum value for the size of objects that are to be labeled. Enter the minimum value in the Show if object area is larger than ... pixel field. All objects that are smaller than this value won't be labeled. This keeps the labeling in the image clear and easy to read.

Selecting the contents of the label

Select the Show measurement name check box to have the name of the chosen measurement parameter shown in the image. With an area measurement, the labeling is then Area 38.1 for example.

Select the Show measurement unit check box to have the unit of the chosen measurement parameter shown in the image, together with the measurement value. With an area measurement, the labeling is then Area 38.1 µm² for example.

Shrink measurement label if the zoom factor is less than 100%

Select the Shrink if the zoom factor is less than 100% check box, if the labeling is to be parallel reduced in size, when you use the zoom function to reduce the image's size to a value smaller than 100%.

Object display

Showing and hiding measurement results in an image

The measurement results will be shown on the image in a special data layer, the measurement layer. Onscreen, image and measurement layer are shown together. The data of each, however, is individually stored in the TIF or VSI image file format. Try and picture the measurement layer as a transparency which is placed over the image. When you measure an image, the image data will not be changed by having the measurement results displayed on it.

You can, at any time, hide or show the measurement layers. To do so, use the Layers tool window. There you have access to all of an image's layers. The eye icon icon_auge identifies all of the layers that are currently on display on your monitor.

Click the eye icon in front of the measurement layer to hide the measurements. Click an empty cell without an eye icon to make the corresponding layer reappear.

In the Object display group, you set the way the detected objects are to be displayed in the image.

Select the Show object check box if the detected objects are to be shown in the image. Each object will be automatically displayed in the color of its current object class.

Select the Outline option when the objects are to be displayed outlined.

Select the Filled option when the objects are to be displayed filled in.

Measurement Results

In the Decimal places field, enter the number of decimal places that are to be shown for the results. Two decimal places are preset, a maximum of 8 decimal places is possible. As well as the labeling in the image, this setting also affects what appears in the Define Classification dialog box, and the Count and Measure Results tool window.

Note: The number of decimal places only influences the display of the values. This display has no influence on the precision of the measurements.
