synchronized public void addTagFoundListener(CodecsTagFoundListener listener)
synchronized public void removeTagFoundListener(CodecsTagFoundListener listener)
public:
event EventHandler<CodecsEnumTagsEventArgs^>^ TagFound
def TagFound(sender,e): # sender: RasterCodecs e: CodecsEnumTagsEventArgs Event Data
The event handler receives an argument of type CodecsEnumTagsEventArgs containing data related to this event. The following CodecsEnumTagsEventArgs properties provide information specific to this event.

Example
using Leadtools;
using Leadtools.Codecs;
using Leadtools.ImageProcessing;
using Leadtools.ImageProcessing.Color;
using Leadtools.Svg;
string tagsFileName;
IList<RasterTagMetadata> myTags;
void EnumTagsExample(string srcFileName, string destFileName)
{
RasterCodecs codecs = new RasterCodecs();

myTags = new List<RasterTagMetadata>();
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);
