Ruler Tool

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.

• Select all objects.

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

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

• Change the Name properties. See Name Dialog Box for Annotations.

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

• Change the binary raster operation (ROP2) code. See ROP2 Dialog Box for Annotations.

• Change the fill mode (transparent, translucent, or opaque) and the fill pattern. See Fill Dialog Box for Annotations.

• Change the foreground and background colors. See Color Dialog Box for Annotations.

• Change the font selection and font characteristics. See Font Dialog Box for Annotations.

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

• Change the fixed properties. See Fixed 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.
