◆ geoTagImage()

bool QgsExifTools::geoTagImage	(	const QString &	imagePath,
		const QgsPointXY &	location,
		const GeoTagDetails &	details = `QgsExifTools::GeoTagDetails()`
	)

static

Writes geotags to the image at imagePath.

The location argument indicates the GPS location to write to the image, as a WGS84 latitude/longitude coordinate.

If desired, extended GPS tags (such as elevation) can be specified via the details argument.

Returns true if writing was successful.

Definition at line 307 of file qgsexiftools.cpp.

◆ getGeoTag()

QgsPoint QgsExifTools::getGeoTag	(	const QString &	imagePath,
		bool &	ok
	)

static

Returns the geotagged coordinate stored in the image at imagePath.

If a geotag was found, ok will be set to true.

If the image contains an elevation tag then the returned point will contain the elevation as a z value.

◆ hasGeoTag()

bool QgsExifTools::hasGeoTag ( const QString & imagePath )

static

Returns true if the image at imagePath contains a valid geotag.

See also: getGeoTag()

Definition at line 232 of file qgsexiftools.cpp.

◆ readTag()

QVariant QgsExifTools::readTag	(	const QString &	imagePath,
		const QString &	key
	)

static

Returns the value of of an exif tag key stored in the image at imagePath.

Since: QGIS 3.22

Definition at line 172 of file qgsexiftools.cpp.

◆ readTags()

QVariantMap QgsExifTools::readTags ( const QString & imagePath )

static

Returns a map object containing all exif tags stored in the image at imagePath.

Since: QGIS 3.22
