Right, the rendered pixel data returned by getOutputData() is always unsigned. Hounsfield Units, i.e. the pixel data after the Modality LUT transformation has been applied, are only available internally.

The internal representation of the pixel data does not only depend on the value of BitsStored but also on the Modality LUT transformation and the value of PixelRepresentation. Why do you care about the internal representation at all? The purpose of the DicomImage class is visualization that means yo...

No, not with dcmdump since this is a textual dump tool, with one exception: the Pixel Data element value can also be extracted to a binary raw file.

I'm sorry but that's how the DICOM Storage Service works: the SCU proposes to send the DICOM object uncompressed (in your case, Implicit VR Little Endian), the SCP accepts this and then, if the DICOM object is actually compressed, it's up to the SCU to decompress it before the transfer. If you want ...

Jan, you mean this commit? Seemed to be an issue for CMake configurations only, right? Autoconf should always have worked since this was tested for the previous releases of the DCMTK.

The storage user is the client program that you use to send the DICOM image (you call it "video data") to the storescp, i.e. the program that created "the log file from the client side used DICOM library" (see your own posting above). What I wanted to say: if your client tool (st...

Please read my previous answer again: it's not DCMTK (i.e. storescp) converting the video data, it's the storage user (which is apparently not based on the DCMTK).

Which operating system and which command shell do you use? I tried a recent DCMTK development version (from this year) with Windows 7 and "cmd.exe" and it works as expected, even if there are spaces in the path name. Using this environment, the quotation marks are no required (i.e. they sh...

Is there some logfile? The logging mechanism in the DCMTK is based on log4cplus, so you could also create a log file, of course. A sample logger configuration file can be found in "dcmtk/oflog/etc/filelog.cfg". Also see this HOWTO: http://support.dcmtk.org/redmine/projects/dcmtk/wiki/Howt...

Since the paths are different (value of environment variable and debug output of storescp) my first guess would be that the space character in the "C:\Program Files (x86)\Test\..." path requires quotation marks around the value. By the way, on Windows systems the DCMTK tools by default use...

This behavior is part of the DICOM Storage Service and depends on the capabilities/configuration of both the Storage SCU and the Storage SCP. Here are a few questions: ⋅  What is the transfer syntax and SOP class of the DICOM "compressed video data"? ⋅  Which Storage SC...

Of course, you can also implement MPPS with the freely available DCMTK since it is a general purpose toolkit :-)

Since DCMTK is a general-purpose DICOM toolkit, all all the requested DICOM services can be implemented. To be more specific... SCU: MPPS, various storage ones (I have no further detail on the storage ones right now) If you need ready-to-use tools or classes: ⋅ For Storage, there are the s...

Pass the DcmFileFormat (or DcmDcmdata) instance to the DicomImage constructor and call DicomImage::createJavaAWTBitmap().
