Reading images from Dicom

[Nikhil P Kookkiri]

Hello all,

I am getting the following error while trying to read images from 'certain' DICOM files. Its not occurring with all DICOM objects. Here is the snippet of the error:

ERROR [stderr] (default task-17) java.lang.IllegalArgumentException: Width (0) and height (0) must be > 0

----------------------

Here is my code:

DicomInputStream dis = new DicomInputStream(new ByteArrayInputStream(Files.readAllBytes(Paths.get(dicomFile.getPath()))));

ImageReader reader = ImageIO.getImageReadersByFormatName("DICOM").next();

reader.setInput(dis);

DicomImageReadParam   readParam =  (DicomImageReadParam) reader.getDefaultReadParam();

reader.set Input(dis);

IIOImage ioImg =reader.readAll(0, readParam);

Strange thing is, it is happening with certain DICOM files only and works well with most of them. I am kind of stuck on how to fix this. Any pointers will be really helpful.

Thanks,

Without a sample, it is not possible to give you an answer. The log above only shows that the image has no pixels but not the root cause.
