findAndGetFloat64

[giaco]

Hello I have a problem with dicom tag array:

DcmDataset *ds = dicom.getDataset();
double *position;
ds->findAndGetFloat64(DCM_ImagePositionPatient,position);

findAndGetFloat64 return the pointer position as NULL.
I have this problem with all tag array.

Thanks a lot in advantage.

Do you mean DcmItem::findAndGetFloat64Array()?

[giaco]

oh yes sorry ds->findAndGetFloat64Array(DCM_ImagePositionPatient,position);

[Jörg Riesmeier]

As you can read in the documentation, findAndGetFloat64Array() is only applicable to data elements with the value representation FD. However, ImagePositionPatient has the value representation DS.

You can use the findAndGetFloat64 (documentation) which is applicable to VR DS. You can use the position parameter to get all three values of attribute Image Position Patient.
