[ome-devel] get annotations java code

[Dominik Lindner (Staff)]

Hi Thomas,

it looks like you're using the java gateway. In that case you can use the "MetadataFacility" to load
the MapAnnotations. Here's a github gist with an example:

Kind Regards,

Dear Omero devs,

I would like to access key value pairs assocaited to an image but created by other users. It seems, thanks to the code provided on the omero website, to extract all annotations from me, but I do not know how to get only annotatins assocaited to a specific image.

here the code I wrote with "image" being an imageData object.

long userId = gateway.getLoggedInUser().getId();
List<String> nsToInclude = new ArrayList<>();
//nsToInclude.add(MapAnnotationData.NS_CLIENT_CREATED);
List<String> nsToExclude = new ArrayList<>();
ParametersI param = new ParametersI();
//param.exp(omero.rtypes.rlong(userId)); // user
param.exp(omero.rtypes.rlong(image.getId())); // image ??
IMetadataPrx proxy = gateway.getMetadataService(ctx);
try {
    List<Annotation> annotations = proxy.loadSpecifiedAnnotations(MapAnnotation.class.getName(), nsToInclude, nsToExclude, param);
    IJ.log(annotations.size() + "  annotations found");
    for (Annotation annotation : annotations) {
        IJ.log(" "+annotation.getClass()+" "+annotation.getId());
        MapAnnotation mapAnnotation = (MapAnnotation) annotation;
        List<NamedValue> list = mapAnnotation.getMapValue();
        for (NamedValue namedValue : list)
            IJ.log(namedValue.name + "  " + namedValue.value);
    }
} catch (ServerError serverError) {
    IJ.log("Pb reading annotation " + serverError.message);
    serverError.printStackTrace();
}



Thanks for any help.

best

Thomas
