Pitney Bowes MapInfo Professional - Manual (Page 214)

• Click the Pick from Map button and click the anchor point you want on the Map or Layout window.
Click the mouse button only once to establish this point.
When the Pick from Map button is disabled, you can select locations directly from the
open map. If a map is not open, you can select another tool (like the Select tool) and use
that tool instead of the Pick from Map functionality. Note:
To return to the default anchor point, click the Reset Anchor button.
2. Decide whether or not you want to lock the anchor point. Click the Lock Anchor Point Position
check box to lock the anchor point.
When you lock the anchor point, you ensure that the anchor point will not be recalculated when you
return to the Map or Layout window. If you do not lock the anchor point, MapInfo Professional
recalculates the anchor point based on the rotated selection. Once the objects are rotated, they may
have a different anchor point.
You cannot maintain an anchor point lock when you change the selection from the Map
window to the Layout window or from the Layout to the Map window. Note:
3. When you have completed these entries or selections, click OK to rotate your object(s).
Understanding an Object's Default Anchor Point
When rotating objects in an editable layer, the default anchor varies depending upon how many objects
you are rotating and the kind of objects you select. If you select:
• A single object (not a polyline), the default anchor point is the object's centroid
• A single polyline or several objects, the default anchor point is the center of the polyline's or the selected
objects minimum bounding rectangle (MBR)
• Multiple objects, the default anchor point is the center of the MBR of the selected objects
Changing your Map Object Attributes
When you double-click a region, line, point or text object with the Select tool, MapInfo Professional
displays an Object Attribute dialog box. This dialog box gives you the object's size, its position, and
other information specific to the object.
For example, if you double-click a region, MapInfo Professional displays the perimeter, centroid, and
area. It also shows the type of distance calculation that was used to obtain these values.
