Member Function Documentation

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.

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.

tagImage()

bool QgsExifTools::tagImage ( const QString &  imagePath, const QString &  tag, const QVariant &  value  )

value	the exif tag value

Returns

true if writing was successful.
