This feature allows to read EXIF maker-notes from Nikon D models (D300, D500, D600, D5100 etc).
None
This example demonstrates how to get NIKON makernotes.
// path to the jpg file
string path = @"C:\\example.jpg";
// initialize JpegFormat
JpegFormat jpegFormat = new JpegFormat(path);
// get makernotes
var makernotes = jpegFormat.GetMakernotes();
if (makernotes != null)
{
// try cast to NikonMakerNotes
NikonMakerNotes nikonMakerNotes = makernotes as NikonMakerNotes;
if (nikonMakerNotes != null)
{
// get quality string
string quality = nikonMakerNotes.Quality;
// get version
byte[] version = nikonMakerNotes.MakerNoteVersion;
}
}
This feature allows to read EXIF maker-notes from Sony xperia, cybershot models.
None
This example demonstrates how to get SONY makernotes.
// path to the jpg file
string path = @"C:\\example.jpg";
// initialize JpegFormat
JpegFormat jpegFormat = new JpegFormat(path);
// get makernotes
var makernotes = jpegFormat.GetMakernotes();
if (makernotes != null)
{
// try cast to SonyMakerNotes
SonyMakerNotes sonyMakerNotes = makernotes as SonyMakerNotes;
if (sonyMakerNotes != null)
{
// get color mode
int? colorMode = sonyMakerNotes.ColorMode;
// get JPEG quality
int? jpegQuality = sonyMakerNotes.JPEGQuality;
}
}
This feature allows to read CANON maker notes in JPEG image.
Added CanonMakerNotes class into namespace GroupDocs.Metadata.Formats.Image
Added CanonCameraSettings class into namespace GroupDocs.Metadata.Formats.Image
This example demonstrates how to get CANON maker-notes.
// path to the jpg file
string path = @"C:\\example.jpg";
// initialize JpegFormat
JpegFormat jpegFormat = new JpegFormat(path);
// get makernotes
var makernotes = jpegFormat.GetMakernotes();
if (makernotes != null)
{
// try cast to CanonMakerNotes
CanonMakerNotes canonMakerNotes = makernotes as CanonMakerNotes;
if (canonMakerNotes != null)
{
// get cammera settings
CanonCameraSettings cameraSettings = canonMakerNotes.CameraSettings;
if (cameraSettings != null)
{
// get lens type
int lensType = cameraSettings.LensType;
// get quality
int quality = cameraSettings.Quality;
// get all values
int[] allValues = cameraSettings.Values;
}
// get firmware version
string firmwareVersion = canonMakerNotes.CanonFirmwareVersion;
}
}
This feature allows to read Panasonic maker notes in JPEG image.
Added PanasonicMakerNotes class into namespace GroupDocs.Metadata.Formats.Image
This example demonstrates how to get Panasonic makernotes.
// path to the jpg file
string path = @"C:\\example.jpg";
// initialize JpegFormat
JpegFormat jpegFormat = new JpegFormat(path);
// get makernotes
var makernotes = jpegFormat.GetMakernotes();
if (makernotes != null)
{
// try cast to PanasonicMakerNotes
PanasonicMakerNotes panasonicMakerNotes = makernotes as PanasonicMakerNotes;
if (panasonicMakerNotes != null)
{
// get firmware version
string firmwareVersion = panasonicMakerNotes.FirmwareVersion;
// get image quality
int? imageQuality = panasonicMakerNotes.ImageQuality;
// get lens type
string lensType = panasonicMakerNotes.LensType;
}
}
The bug related to absence of XMP metadata after removing EXIF geo-location has been resolved.
None
This example demonstrates how to remove EXIF geo-location.
// path to the jpg file
string path = @"C:\\example.jpg";
// initialize JpegFormat
JpegFormat jpegFormat = new JpegFormat(path);
// check if JPEG contains XMP metadata
if (jpegFormat.HasXmp)
{
// remove GPS location
jpegFormat.RemoveGpsLocation();
// update Dublin Core format in XMP
jpegFormat.XmpValues.Schemes.DublinCore.Format = "image/jpeg";
// and commit changes
jpegFormat.Save();
}
