The Leadtools SDK allows for a document's metadata information to be accessed by using a few simple commands.

Below are a few relevant links to our LEADTOOLS Online Documentation that will elaborate further on the example below.

The code below shows how to check to see if the file provided supports housing metadata and outputs the contained metadata if it does contain any.

Code:

string srcFile = @"TODO: Modify this file path";

using (var rasterCodecs = new RasterCodecs())
using (var fileInfo = rasterCodecs.GetInformation(srcFile, false))
{
   Console.WriteLine("Format: {0}", fileInfo.Format);
   
   // Check if metadata is supported for the specified file format
   bool isMetadataItemsSupported = RasterCodecs.MetadataItemsSupported(fileInfo.Format);
   Console.WriteLine("isMetadataItemsSupported: {0}", isMetadataItemsSupported);
   
   if (isMetadataItemsSupported)
   {
      // Read metadata items
      IDictionary<string, string> metadata = null;
      try
      {
         metadata = rasterCodecs.ReadMetadataItems(srcFile, 1);
      }
      catch (Exception ex)
      {
         Console.WriteLine("Unable to read metadata: {0}", ex.message);
      }
      
      if (metadata != null)
      {
         Console.WriteLine("Items count: {0}", metadata.Count);
         foreach (var item in metadata)
            // Key ex: RasterCodecs.FileMetadataKeyAuthor
            Console.WriteLine("{0}: {1}", item.Key, item.Value);
      }
   }
}
Console.ReadLine();
