Support Storing XMP Tags in Aspose.Imaging for .NET

Aspose.Imaging for .NET is a powerful library that allows you to work with various image formats in the .NET environment. In this tutorial, we will explore how to support storing XMP (Extensible Metadata Platform) tags in Aspose.Imaging for .NET. XMP tags are essential for adding metadata information to images, making it easier to organize and manage your digital assets. We’ll break down the process into multiple steps to help you understand how to achieve this.

Prerequisites

Before we begin, ensure you have the following prerequisites in place:

Import Namespaces

In your .NET project, import the necessary namespaces for working with Aspose.Imaging:

using Aspose.Imaging;
using Aspose.Imaging.Exif;
using Aspose.Imaging.FileFormats.Dicom;

Now, let’s dive into the step-by-step guide to support storing XMP tags using Aspose.Imaging for .NET.

Step 1: Load the DICOM Image

Begin by loading the DICOM image you want to work with. Replace "Your Document Directory" with the actual directory path where your DICOM image is located.

string dataDir = "Your Document Directory";
using (DicomImage image = (DicomImage)Image.Load(dataDir + "file.dcm"))
{
    // Your code goes here
}

Step 2: Create an XMP Packet and Dicom Package

Create an XmpPacketWrapper and DicomPackage to store your metadata. You can set various metadata fields, such as institution, manufacturer, patient details, series information, and study details.

XmpPacketWrapper xmpPacketWrapper = new XmpPacketWrapper();
DicomPackage dicomPackage = new DicomPackage();

dicomPackage.SetEquipmentInstitution("Test Institution");
dicomPackage.SetEquipmentManufacturer("Test Manufacturer");
dicomPackage.SetPatientBirthDate("19010101");
dicomPackage.SetPatientId("010101");
dicomPackage.SetPatientName("Test Name");
dicomPackage.SetPatientSex("M");
dicomPackage.SetSeriesDateTime("19020202");
dicomPackage.SetSeriesDescription("Test Series Description");
dicomPackage.SetSeriesModality("Test Modality");
dicomPackage.SetSeriesNumber("01");
dicomPackage.SetStudyDateTime("19030303");
dicomPackage.SetStudyDescription("Test Study Description");
dicomPackage.SetStudyId("02");
dicomPackage.SetStudyPhysician("Test Physician");

xmpPacketWrapper.AddPackage(dicomPackage);

Step 3: Save the Image with XMP Metadata

Now, save the image with the added XMP metadata using the DicomOptions class.

string outputFile = dataDir + "output.dcm";
image.Save(outputFile, new DicomOptions() { XmpData = xmpPacketWrapper });

Step 4: Verify the XMP Tags

Load the saved image and compare the DICOM information before and after adding XMP tags.

using (DicomImage imageSaved = (DicomImage)Image.Load(outputFile))
{
    List<string> originalDicomInfo = image.FileInfo.DicomInfo;
    List<string> imageSavedDicomInfo = imageSaved.FileInfo.DicomInfo;
    int tagsCountDiff = Math.Abs(imageSavedDicomInfo.Count - originalDicomInfo.Count);
}

Conclusion

In this tutorial, we learned how to support storing XMP tags in DICOM images using Aspose.Imaging for .NET. Adding metadata to your images is crucial for organization and management. Aspose.Imaging simplifies this process and empowers you to efficiently work with image metadata.
