◆ dms2dd()
| double te::qt::plugins::photolayer::ExifGpsMetadata::dms2dd |
( |
double |
degree, |
|
|
double |
minute, |
|
|
double |
second |
|
) |
| |
|
protected |
Function used to convert from degree, minute, second to decimal degree.
- Parameters
-
| degree | Reference value to degree information |
| minute | Reference value to minute information |
| second | Reference value to second information |
- Returns
- double value with decimal degree information
◆ fixValue()
| std::string te::qt::plugins::photolayer::ExifGpsMetadata::fixValue |
( |
const std::string & |
value | ) |
|
|
protected |
Function used to remove "(" and ")" from string.
- Returns
- string with only value contents
◆ getAltitude()
| double te::qt::plugins::photolayer::ExifGpsMetadata::getAltitude |
( |
| ) |
|
Function used to get the information about altitude.
- Returns
- Double value with altitude information.
- Note
- GPSAltitude - Indicates the altitude based on the reference in GPSAltitudeRef. Altitude is expressed as one RATIONAL value. The reference unit is meters.
GPSAltitudeRef - Indicates the altitude used as the reference altitude.If the reference is sea level and the altitude is above sea level, 0 is given.If the altitude is below sea level, a value of 1 is given and the altitude is indicated as an absolute value in the GPSAltitude tag.The reference unit is meters.
◆ getDateTime()
| std::string te::qt::plugins::photolayer::ExifGpsMetadata::getDateTime |
( |
| ) |
|
Function used to get the date time information.
- Returns
- String value with date time information.
- Note
- DateTimeOriginal - The date and time when the original image data was generated. For a DSC the date and time the picture was taken are recorded. The format is "YYYY:MM:DD HH:MM:SS" with time shown in 24-hour format, and the date and time separated by one blank character [20.H]. When the date and time are unknown, all the character spaces except colons (":") may be filled with blank characters, or else the Interoperability field may be filled with blank characters.
◆ getDMS()

| |
|
protected |
Function used to get the degree, minute, second information from a exif string value.
- Parameters
-
| value | Exif string value with dms information |
| degree | Reference value to get degree information |
| minute | Reference value to get minute information |
| second | Reference value to get second information |

second |
|
) |
| |
Function used to get the latitude information.
- Parameters
-
| degree | Reference value to get degree information |
| minute | Reference value to get minute information |
| second | Reference value to get second information |
- Note
- GPSLatitude - Indicates the latitude. The latitude is expressed as three RATIONAL values giving the degrees, minutes, and seconds, respectively.
GPSLatitudeRef - Indicates whether the latitude is north or south latitude. The ASCII value 'N' indicates north latitude, and 'S' is south latitude.
◆ getLocation()
| te::gm::Point* te::qt::plugins::photolayer::ExifGpsMetadata::getLocation |
( |
| ) |
|
Function used to get a geometry with raster gps location.
- Returns
- Point geometry with raster location if it was readed correctly.

|
) |
| |
Function used to get the longitude information.
- Parameters
-
| degree | Reference value to get degree information |
| minute | Reference value to get minute information |
| second | Reference value to get second information |
- Note
- GPSLongitude - Indicates the longitude. The longitude is expressed as three RATIONAL values giving the degrees, minutes, and seconds, respectively.
GPSLongitudeRef - Indicates whether the longitude is east or west longitude. ASCII 'E' indicates east longitude, and 'W' is west longitude.
◆ HasExifGpsInfo()
| static bool te::qt::plugins::photolayer::ExifGpsMetadata::HasExifGpsInfo |
