TIOParams.EXIF_GPSLongitude

TIOParams.EXIF_GPSLongitude


Declaration

property EXIF_GPSLongitude: Double;


Description

Returns the longitude in decimal degrees where the photo was taken (if the camera supports GPS).

Notes:
- This uses the following EXIF properties: EXIF_GPSLongitudeDegrees, EXIF_GPSLongitudeMinutes, EXIF_GPSLongitudeSeconds and EXIF_GPSLongitudeRef
- To save GPS data, you must set EXIF_GPSVersionID to '2.2.0.0' (or use the const, GPS_Version_ID)


Examples

// Write EXIF data to the current file
ImageEnView1.IO.Params.EXIF_GPSLatitude := StrToFloat( edtEXIF_GPSLatitude.Text );
ImageEnView1.IO.Params.EXIF_GPSLongitude := StrToFloat( edtEXIF_GPSLongitude.Text );
ImageEnView1.IO.Params.EXIF_GPSVersionID := GPS_Version_ID;
ImageEnView1.IO.InjectJpegEXIF('D:\GPSStamped.jpg');

// Update the GPS EXIF data in a file
io := TImageEnIO.create(nil);
try
  io.ParamsFromFile( FilenameStr );

  io.Params.EXIF_GPSLatitude := GPSLatitudeFloat;
  io.Params.EXIF_GPSLongitude := GPSLongitudeFloat;
  io.Params.EXIF_GPSVersionID := GPS_Version_ID;

  io.InjectJpegEXIF( FilenameStr );
finally
  io.Free;
end;
