Hello, Here is the code sample which illustrates how to add tags to EXIF and IPTC metadata in JPEG: Code:
using (Aurigma.GraphicsMill.Bitmap bitmap = new
Aurigma.GraphicsMill.Bitmap("sample.jpg"))
{
Aurigma.GraphicsMill.Codecs.JpegEncoderOptions encoderOptions = new
Aurigma.GraphicsMill.Codecs.JpegEncoderOptions(
100, false);
//EXIF
Aurigma.GraphicsMill.Codecs.ExifDictionary exif = new
Aurigma.GraphicsMill.Codecs.ExifDictionary();
exif[Aurigma.GraphicsMill.Codecs.ExifDictionary.Software] =
"Aurigma Graphics Mill";
encoderOptions.Exif = exif;
//IPTC
Aurigma.GraphicsMill.Codecs.IptcDictionary iptc = new
Aurigma.GraphicsMill.Codecs.IptcDictionary();
iptc[Aurigma.GraphicsMill.Codecs.IptcDictionary.Category] = "Nat";
iptc[Aurigma.GraphicsMill.Codecs.IptcDictionary.CopyrightNotice] =
"Aurigma Inc.";
iptc[Aurigma.GraphicsMill.Codecs.IptcDictionary.Keyword] =
"mountain";
encoderOptions.Iptc = iptc;
bitmap.Save("MetaData.jpg", encoderOptions);
}
Additional information about metadata using you can read in the Working with Metadata section of the online help. Edited by user Wednesday, October 29, 2008 12:29:57 PM(UTC)

Hello, Here is the code sample which shows how to read tags value from EXIF: Code:string imageDesc = null;
string model = null;
string make = null;
using(Aurigma.GraphicsMill.Codecs.JpegReader reader = new
Aurigma.GraphicsMill.Codecs.JpegReader("sample.jpg"))
{
Aurigma.GraphicsMill.Codecs.ExifDictionary exif = reader.Exif;
if(exif.Contains(
Aurigma.GraphicsMill.Codecs.ExifDictionary.ImageDescription))
imageDesc = (string)exif[
Aurigma.GraphicsMill.Codecs.ExifDictionary.ImageDescription];
if(exif.Contains(
Aurigma.GraphicsMill.Codecs.ExifDictionary.Model))
model = (string)exif[
Aurigma.GraphicsMill.Codecs.ExifDictionary.Model];
if (exif.Contains(
Aurigma.GraphicsMill.Codecs.ExifDictionary.Model))
make = (string)exif[
Aurigma.GraphicsMill.Codecs.ExifDictionary.Make];
}
You can read more information how to read/write tags from/to EXIF and IPTC in the Loading or Saving EXIF and IPTC Metadata article. Edited by user Wednesday, October 29, 2008 12:29:27 PM(UTC)
