Get XMP metadata from EPS file using .NET
You can check the quality of Aspose.Page XMP Metadata working with Metadata web app.
In order to extract XMP metadata from EPS file it is necessary to do several steps:
- Initialize an input stream for input EPS file.
- Create an instance of PsDocument from created earlier input stream.
- Get an instance of XmpMetadata from the PsDocument. If given EPS file doesn’t contain XMP metadata the new one will be created, filled in with values from PS metadata comments and returned to you.
- Now you can view values of metadata fields.
Following code snippet shows how to extract XMP metadata from EPS file in C#:
1// For complete examples and data files, please go to https://github.com/aspose-page/Aspose.Page-for-.NET
2// The path to the documents directory.
3string dataDir = RunExamples.GetDataDir_WorkingWithXMPMetadataInEPS();
4// Initialize EPS file input stream
5System.IO.FileStream psStream = new System.IO.FileStream(dataDir + "get_input.eps", System.IO.FileMode.Open, System.IO.FileAccess.Read);
6// Create PsDocument instance from stream
7PsDocument document = new PsDocument(psStream);

9try
10{
11 // Get XMP metadata. If EPS file doesn't contain XMP metadata we get new one filled with values from PS metadata comments (%%Creator, %%CreateDate, %%Title etc)
12 XmpMetadata xmp = document.GetXmpMetadata();
13
14 // Get "CreatorTool" value
15 if (xmp.Contains("xmp:CreatorTool"))
16 Console.WriteLine("CreatorTool: " + xmp["xmp:CreatorTool"].ToStringValue());
17
18 // Get "CreateDate" value
19 if (xmp.Contains("xmp:CreateDate"))
20 Console.WriteLine("CreateDate: " + xmp["xmp:CreateDate"].ToStringValue());
21
22 // Get a width of a thumbnail image if exists
23 if (xmp.Contains("xmp:Thumbnails") && xmp["xmp:Thumbnails"].IsArray)
24 {
25 XmpValue val = xmp["xmp:Thumbnails"].ToArray()[0];
26 if (val.IsNamedValues && val.ToDictionary().ContainsKey("xmpGImg:width"))
27 Console.WriteLine("Thumbnail Width: " + val.ToDictionary()["xmpGImg:width"].ToInteger());
28 }
29
30 // Get "format" value
31 if (xmp.Contains("dc:format"))
32 Console.WriteLine("Format: " + xmp["dc:format"].ToStringValue());
33
34 // Get "DocumentID" value
35 if (xmp.Contains("xmpMM:DocumentID"))
36 Console.WriteLine("DocumentID: " + xmp["xmpMM:DocumentID"].ToStringValue());
37
38}
39finally
40{
41 psStream.Close();
