Export in RTStruct format

Development
1

I want to export a file in rtstruct format, but I don’t know how to proceed.

I’ve seen in the adapters folder a RTStuct folder and I want to export the file to have a RTStruct

In the example the button execute this

addButtonToToolbar({
title: "EXPORT",
onClick: async () => {
    const volume = cache.getVolume(volumeId);
    const segUID = segmentationRepresentationUID[0];

    const images = volume.getCornerstoneImages();

    const labelmapObj =
        Cornerstone3D.Segmentation.generateLabelMaps2DFrom3D(
            segmentationVolume
        );

    // Generate fake metadata as an example
    labelmapObj.metadata = [];
    labelmapObj.segmentsOnLabelmap.forEach(segmentIndex => {
        const color = segmentation.config.color.getColorForSegmentIndex(
            toolGroupId,
            segUID,
            segmentIndex
        );

        const segmentMetadata = generateMockMetadata(segmentIndex, color);
        labelmapObj.metadata[segmentIndex] = segmentMetadata;
 });

    const generatedSegmentation =
        Cornerstone3D.Segmentation.generateSegmentation(
            images,
            labelmapObj,
            metaData
        );

    downloadDICOMData(generatedSegmentation.dataset, "mySEG.dcm");
}
});

with this I can export a SEG but I want to export a RTSTRUCT

This is what I tried to export but getSegmentation does not exist and I don’t know how to achieve this.

addButtonToToolbar({
title: "EXPORTAR",
onClick: async () => {
    const volume = cache.getVolume(volumeId);
    const segUID = segmentationRepresentationUID[0];
    const images = volume.getCornerstoneImages();
    console.log(volume);
    // Get the segmentation object.
    const segmentation = volume.getSegmentation(segUID);
    // Get the metadata provider.
    const metadataProvider = Cornerstone3D.MetadataProvider.getDefault();

    // Get the DICOM metadata store.
    const DicomMetadataStore = Cornerstone3D.DicomMetadataStore.getDefault();

    // Get the Cornerstone cache.
    const cornerstoneCache = Cornerstone3D.CornerstoneCache.getDefault();

    // Get the Cornerstone tools enums.
    const cornerstoneToolsEnums = Cornerstone3D.CornerstoneToolsEnums.getDefault();

    // Get the VTK utils.
    const vtkUtils = Cornerstone3D.VTKUtils.getDefault()

// Generate the RTSTRUCT report.
    const rtsReport = generateRTSSFromSegmentations(
    [segmentation], // Array of segmentations.
    metadataProvider, // Metadata provider.
    DicomMetadataStore, // DICOM metadata store instance.
    cornerstoneCache, // Cornerstone cache instance.
    cornerstoneToolsEnums, // Cornerstone tools enums.
    vtkUtils // VTK utils.
);

// Get the DICOM dataset from the RTSTRUCT report.
const dataset = rtsReport.dataset;

// Export the RTSTRUCT file.
   downloadDICOMData(dataset, "myRTSTRUCT.dcm");

Could you please help me?
