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.
https://www.leadtools.co...orking-with-markers.htmlhttps://www.leadtools.co...s-readmetadataitems.htmlhttps://www.leadtools.co...astermarkermetadata.htmlhttps://www.leadtools.co...l/rastertagmetadata.htmlhttps://www.leadtools.co...stercommentmetadata.htmlThe 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();
