Property Value

The tagged data type. Valid values are:

Value	Meaning
RasterTagMetadataDataType.Byte	Byte
RasterTagMetadataDataType.Ascii	Byte in the range of 0 to 255
RasterTagMetadataDataType.SByte	Byte used as signed number in the range of -128 to +127
RasterTagMetadataDataType.Undefined	Byte, with application-defined usage
RasterTagMetadataDataType.UInt16	Two bytes, unsigned
RasterTagMetadataDataType.Int16	Two bytes, signed
RasterTagMetadataDataType.UInt32	Four bytes, unsigned
RasterTagMetadataDataType.Int32	Four bytes, signed
RasterTagMetadataDataType.Single	Four bytes used as a floating point number
RasterTagMetadataDataType.Double	Eight bytes used as a double-precision floating point number
RasterTagMetadataDataType.URational	Eight bytes, used as a pair of unsigned long integers, where the first number is the numerator and the second is the denominator of a fraction
RasterTagMetadataDataType.Rational	Eight bytes, used as a pair of signed long integers, where the first number is the numerator and the second is the denominator of a fraction

   codecs.TagFound += new EventHandler<CodecsEnumTagsEventArgs>(codecs_TagFound); 
   codecs.EnumTags(srcFileName, 1); 
   codecs.TagFound -= new EventHandler<CodecsEnumTagsEventArgs>(codecs_TagFound); 
 
   // We read all the tags now, save them to the file 
   Debug.WriteLine("{0} tags read, saving them to the destination file", myTags.Count); 
   codecs.WriteTags(destFileName, 1, myTags); 
 
   // Clean up 
   codecs.Dispose(); 
} 
 
void codecs_TagFound(object sender, CodecsEnumTagsEventArgs e) 
{ 
   Debug.WriteLine("Tag: Id={0}, Count={1}, Type={2}, Cancel={3}", e.Id, e.Count, e.MetadataType, e.Cancel); 
 
   // Read this tag from the file and add it to our collection 
   RasterCodecs codecs = sender as RasterCodecs; 
   RasterTagMetadata tag = codecs.ReadTag(tagsFileName, 1, e.Id); 
   myTags.Add(tag);
