Hi, all. Is it possible to read metadata from ARW (Sony RAW format) and Cr2 format? Regards, Carsten

Hi Carsten, Did you try RawReader? If it does not work, please create a support ticket and send us few examples, we will check it out. Also, if you need other metadata than EXIF (e.g. some RAW-specific data), please describe it as well. Edited by user Thursday, December 12, 2013 6:08:43 PM(UTC)

RawReader works. But Graphic Mill recognize FileFormat.Tiff...:-( I sent you an email with the attached image. Regards, Carsten

Well, the reason is that RAW format is based on TIFF. Do you need to distinguish RAW and TIFF without loading it into memory?

What do you mean? I only want to extract all metadata of the files. :-)

Carsten, Ok, could you post here a code snippet you use to load EXIF from such files?

Of course: Code: var properties = new List<MetaDataItem>();
using (var reader = new RawReader(s))
{
if (reader.Exif == null)
{
properties.Add(new MetaDataItem("", "The image does not have EXIF data", ""));
return properties;
}
ExifDictionary exifData = reader.Exif;
/* You can leave this out. Already discussed in other case...;-)
string strLatitude = exifData.GetItemString(ExifDictionary.GpsLatitude);
string strLongitude = exifData.GetItemString(ExifDictionary.GpsLongitude);
string strLatitudeRef = exifData.GetItemString(ExifDictionary.GpsLatitudeRef);
string strLongitudeRef = exifData.GetItemString(ExifDictionary.GpsLongitudeRef);
string latitudeValue = ConvertDegree(strLatitude, strLatitudeRef);
string longitudeValue = ConvertDegree(strLongitude, strLongitudeRef);
item.GpsData = new string[]
{
latitudeValue,
longitudeValue
};
*/
foreach (object key in exifData.Keys)
{
string tag = string.Format("{0:X}", key);
string name = exifData.GetKeyDescription(key);
string value = (ShrinkString(exifData.GetItemString(key), 50));
properties.Add(new MetaDataItem(tag, name, value));
}
}

MetaDataItem Class: Code: [Serializable()]
public class MetaDataItem
{
public string Tag { get; set; }
public string Description { get; set; }
public string Value { get; set; }
public MetaDataItem(string t, string d, string v)
{
Tag = t;
Description = d;
Value = v;
}
}

If s is a RAW file name, it should work fine. Where do you receive FileFormat.Tiff?

"s" is a Stream. Before the above code I make following if statement: Code: FileFormat format = ImageReader.RecognizeFormat(s);
if (format == FileFormat.Raw || format == FileFormat.Tiff)

BTW: which translations do you mean in the support case?

Hello, We will take a look at this problem at the beginning of 2014 and hopefully the fix will be included in version 7 which will be available in 2014Q1. |
