Interface ILatLonFormat2

All Superinterfaces:

Serializable

All Known Implementing Classes:

LatLonFormat

public interface ILatLonFormat2
extends Serializable

Provides access to members that format Latitudes and Longitudes.

Description

The members in the ILatLonFormat2 interface define how the ValueToString method in the associated INumberFormat interface formats numbers.

The LatLonFormat coclass also inherits the INumericFormat interface, so both these interface's properties determine how numbers are formatted.

When To Use

Use the ILatLonFormat2 interface to format numbers that represent a latitude or longitude.

Indicates if a directional letter (N-S-E-W) is appended to the formatted number.

Description

The ShowDirections property sets or returns an indicator that tells whether to append a directional letter designation (N, S, E, or W) when the ValueToString method in the associated INumberFormat interface formats numbers.

Description

The GetDMS method returns the degrees, minutes, and seconds values for a given decimal degree latitudinal or longitudinal value.

isLatitude

boolean isLatitude()
                   throws IOException,
                          AutomationException

Indicates if a formatted number is a latitude or not.

Description

The IsLatitude property sets or returns an indicator that tells whether the curvature of the coordinate system causes latitude labels to be placed on top or below the dataframe border, or for longitude labels that appear to the right or left of the dataframe border. It also determines the directional label appended to the format when the ValueToString method in the associated INumberFormat interface formats numbers.

The settings for ShowDirections are:

Setting	Description
False	(Default) Latitude labels are placed on top of the dataframe border. Longitude labels are placed to the left of the dataframe border. If ShowDirections is True, a directional letter designation of either E or W is appended to the format, for example, 23°E.
True	Latitude labels are placed below the dataframe border. Longitude labels are placed to the right of the dataframe border. If ShowDirections is True, a directional letter designation of either N or S is appended to the format, for example, 17°N.

Remarks

When used with the IDMSGridLabel interface, it sets an indicator to specify that latitude labels will be placed on top of the data frame border, and longitude labels will be placed to the left of the data frame border. If True, the directional letter will be either N or S; with IDMSGridLabel, latitude labels are placed below the data frame border and longitude labels are placed to the right.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux

Returns:

The isLat

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.
