Label Position buttons

Use the default position (Anchor Point) buttons and the label offset to specify the label's placement. The anchor point is the label's position relative to the map object.

Click one of the buttons to select an anchor point. The default anchor point varies with the type of map object you are labeling: Regions default to Center, Lines default to Above Center, and Points default to Right.

Label offset

Set the number of points (a measurement of text size) that a label is placed from its anchor point.

Regions

These options display when the layer has region objects.

Label at centroid

Place labels at region center points.

Auto position label within region

If you select this, then MapInfo Pro ignores the Label Position setting for region labels. The Label Position setting still affects point or line labels in the same layer, and MapInfo Pro places these labels around their centroid.

Allow font reduction for better fit

Lets you specify a percent as the limit to which label font sizes will reduce to make labels fit within region boundaries. Labels will not reduce past this value. You can use the slider or select the value from the drop-down list. The default value is 50%.

Maximum # of font sizes

Limits the number of font sizes to use when resizing labels for a region layer. The default value is four (4).

Confine labels to region boundary

Select to display only the labels that fit within their region boundaries.

Place outside if necessary (callout)

Select to display labels that do not fit within their region boundaries by positioning them outside of their region with a callout (a line connecting the label to its region). This option is only available after selecting the Confine labels to region boundary check box.

Lines

These options display when the layer has line objects.

Horizontal (Orientation)

Select to display all labels horizontally.

Rotated (Orientation)

Select to run the label text parallel to the line segment. Using this option, a horizontal polyline would display parallel horizontal labels and a vertical polyline would display vertical street labels.

Curved (Orientation)

Select to display the label along the curve of the polyline or arc segment.

Auto position along line

If a polyline bends too sharply, then it might not be possible to draw a curved label at that location along the polyline. This option chooses one of the three most suitable locations along a polyline to place a curved label. Choosing this option increases the chance of a label being drawn. Preference is given to the straightest and most horizontal parts of a polyline.

Allow rotated as fallback

Select to have curved labels that cannot be drawn fall back to being normal labels that are rotated.

Overhang

Use this slider bar to indicate the amount a label may extend beyond the end of a line (such as a street) The default amount is 40%.

Label Fit and Density

Discard Label

Select to remove labels that overlap each other.

Try other positions

Avoid overlapping labels (to display more labels) by repositioning them around the object the label is describing.

Allow overlapping text

Allow labels to be drawn on top of each other. Labels may not display when they overlap labels that have a higher priority on the map.

Allow duplicate text

Allow duplicate labels for different objects to display, for example, (Portland, OR) and (Portland, ME). Use this option with street maps to label street segments individually.

Label partial objects

Label polylines and objects whose centroids are not visible in the Map window. This only applies to autolabels. Also, when you customize a label, the location of the label will not change.

Label Visibility

On

Check to allow display of labels.

Off

Check to prevent display of automatic labels; labels added using the Label command will display.

Within zoom range

Select to display labels within a specified zoom range, much the same way that you display map layers within a certain zoom range. When labeling a dense table of streets such as a StreetPro Display layer, only a few of the streets will be labeled when the map is zoomed out.

Note: When a layer is outside of its zoom range, the layer name is dimmed and there is an asterisk (*) beside the Visible On/Off check box. If the zoom range is set to Within zoom range and the map's zoom level is out of the label's min/max zoom range, then the Automatic Labels do not display in the map.

Min Zoom

Specify the minimum distance at which the selected layer is visible.

Max Zoom

Specify the maximum distance at which the selected layer is visible.
