Ruler Tool

Note: This topic is for Document/Medical s only.

The ruler annotation object is a line that can be used to measure the distance between two points of the original image. Holding down the Shift key while drawing the ruler will draw the ruler annotation object at an angle that is a multiple of 45 degrees.

In design mode, click on the object with the right mouse button to do the following:

• Undo the last user action.

• Cut or copy the object to the clipboard.

• Delete the object.

• Bring the object to the front or send it to the back.

• Select all objects.

• Lock and unlock annotation objects. See Password Dialog Box for Annotations

• Set and manage hyperlink properties for an object or group of objects. Note: The actual management of a hyperlink must be done through low-level implementation. Only the Menu Item "Hyperlink" and an associated event are provided through the automation object. For more information, refer to Implementing Annotation Hyperlinks.

• Change the line width and style properties. See Line Dialog Box for Annotations.

• Change the foreground color. See Color Dialog Box for Annotations.

• Change the ROP2 code. See ROP2 Dialog Box for Annotations

• Change the measurement units, precision and gauge length. See Ruler Dialog Box for Annotations

You cannot flip, reverse, or rotate a ruler clip. If you flip, reverse, or rotate a container that includes a ruler, the object will move to the new position, but will retain its orientation.

For low-level implementation details, refer to Ruler Annotation Object.
