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.

Definition at line 445 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.

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.

◆ readTags()

QVariantMap QgsExifTools::readTags ( const QString &  imagePath)
static

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

Since

Definition at line 327 of file qgsexiftools.cpp.

◆ tagImage()

bool QgsExifTools::tagImage ( const QString &  imagePath,
