Detailed Description

Contains methods for converting coordinates for display in various formats.

QgsCoordinateFormatter contains static methods for converting numeric coordinates into different formats, for instance as degrees, minutes, seconds values. Note that QgsCoordinateFormatter has no consideration for the validity of converting coordinates to the various display formats, and it is up to the caller to ensure that sensible formats are used for particular coordinates. For instance, ensuring that only geographic coordinates and not projected coordinates are formatted to degree based formats.

Member Enumeration Documentation

Format

enum QgsCoordinateFormatter::Format

Available formats for displaying coordinates.

Enumerator
FormatPair	Formats coordinates as an "x,y" pair.
FormatDegreesMinutesSeconds	Degrees, minutes and seconds, eg 30 degrees 45'30".
FormatDegreesMinutes	Degrees and decimal minutes, eg 30degrees 45.55'.
FormatDecimalDegrees	Decimal degrees, eg 30.7555 degrees.

Definition at line 46 of file qgscoordinateformatter.h.

FormatFlag

enum QgsCoordinateFormatter::FormatFlag

Flags for controlling formatting of coordinates.

Enumerator
FlagDegreesUseStringSuffix	Include a direction suffix (eg 'N', 'E', 'S' or 'W'), otherwise a "-" prefix is used for west and south coordinates.
FlagDegreesPadMinutesSeconds	Pad minute and second values with leading zeros, eg '05' instead of '5'.

Member Function Documentation

asPair()

QString QgsCoordinateFormatter::asPair ( double  x, double  y, int  precision = 12, Qgis::CoordinateOrder  order = Qgis::CoordinateOrder::XY  )

static

Formats coordinates as an "\a x,\a y" pair, with optional decimal precision (number of decimal places to include).

Since QGIS 3.26 the optional order argument can be used to control the order of the coordinates.

Definition at line 79 of file qgscoordinateformatter.cpp.

format()

QString QgsCoordinateFormatter::format ( const QgsPointXY &  point, QgsCoordinateFormatter::Format  format, int  precision = 12, FormatFlags  flags = FlagDegreesUseStringSuffix, Qgis::CoordinateOrder  order = Qgis::CoordinateOrder::XY  )

static

Formats a point according to the specified parameters.

The format argument indicates the desired display format for the coordinate.

The precision argument gives the number of decimal places to include for coordinates.

Optional flags can be specified to control the output format.

Since QGIS 3.26 the optional order argument can be used to control the order of the coordinates.

Definition at line 62 of file qgscoordinateformatter.cpp.

formatX()

QString QgsCoordinateFormatter::formatX ( double  x, QgsCoordinateFormatter::Format  format, int  precision = 12, FormatFlags  flags = FlagDegreesUseStringSuffix  )

static

Formats an x coordinate value according to the specified parameters.

The format argument indicates the desired display format for the coordinate.

The precision argument gives the number of decimal places to include for coordinates.

Optional flags can be specified to control the output format.

formatY()

QString QgsCoordinateFormatter::formatY ( double  y, QgsCoordinateFormatter::Format  format, int  precision = 12, FormatFlags  flags = FlagDegreesUseStringSuffix  )

static

Formats a y coordinate value according to the specified parameters.

The format argument indicates the desired display format for the coordinate.

The precision argument gives the number of decimal places to include for coordinates.

Optional flags can be specified to control the output format.

formatX()

Definition at line 43 of file qgscoordinateformatter.cpp.

separator()

QChar QgsCoordinateFormatter::separator ( )

static

Returns the character used as X/Y separator, this is a , on locales that do not use , as decimal separator, it is a space otherwise.
