Re: unable to read a file
I am sorry, but I still don't know what you want to do and what you mean by "how to convert the SOP class". In order to help you, you should describe your problem in more detail, i.e. what do you want to achieve, what have you tried, what does not work, etc.

The second file is not an image:

Re: unable to read a file
Short answer: The public and freely available DCMTK does not support decompression of JPEG 2000-compressed DICOM images unless you use an extension such as DCMJP2K.

Re: 32 bit unsigned overflow in dcmjpeg/libsrc/djcodecd.cc
Thank you for your report. In fact, this issue has been fixed only recently (i.e. after the release of DCMTK 3.6.8 ). See this commit: https://git.dcmtk.org/?p=dcmtk.git;a=co ... 4a6cce06dd

Re: DCMTK Latest version update issue
Everything you need to know is described in the INSTALL file. How to compile the DCMTK with CMake can be found in the "BUILDING" section.

Re: DCMTK Latest version update issue
Of course, there are changes in the dcmdata module (including the dcmdata library). because i download the zip file from this site "https://dicom.offis.de/download/dcmtk/dcmtk368/" inside this there is no lib folder available, I can't saw that. so, i use older version lib folder. We never ...

Re: how to remove all frames from dicom
If there is no requirement that the result would still be a valid DICOM dataset/file, you could remove the Pixel Data (7fe0,0010) element by calling something like this on the main DICOM dataset: dataset->findAndDeleteElement(DCM_PixelData); However, unless you access the Pixel Data element (7fe0,00...

Re: DCMTK Latest version update issue
Since DcmtkWrapper seems to be part of your program/app (not of the DCMTK): Did you start with a clean development environment, e.g. by calling "make clean" or the like?

Re: how to remove all frames from dicom
Unfortunately, your question is not clear. Do you want to remove the Pixel Data element or to set its length to 0 (i.e. clear its value)? What would be the value of Rows and Columns then? What about other data elements that refer to the image frames (pixel data)? In both cases, this would make the D...

Re: Difference in ImageStatus after processing dicom file using dcmtk library
Can you expalin how is transfer syntax related? I thought I already explained this in my previous posting: for uncompressed pixel data (e.g. Explicit VR Little Endian Transfer Syntax), the maximum element length is limited to about 4.2 GB (due to the size of the element length field, which is 32-bi...

Re: How to convert a dicom file from RGB format into MONOCHROME2?
Yes, if all frames are actually selected for being loaded/processed (see DicomImage constructor).Does DicomImage::createMonochromeImage() convert all the frames from RGB to MONOCHROME2?

Re: When Decompressing DICOM get "Tag not found" error
Unfortunately, the log output of dcmdjpeg is not very useful in this case, but after looking at the dump output of the DICOM file, it seems that the mandatory Photometric Interpretation (0028,0004) attribute is missing in the main dataset. Also using dcmj2pnm gives you more details (e.g. another dat...

Re: dcm2pdf usage question
As the documentation (man page) says: "The dcm2pdf utility reads a DICOM file of the Encapsulated PDF Storage SOP Class (dcmfile-in), extracts the embedded PDF document and writes it to an output file (pdffile-out)." That means, this tool does not support what you expect. If you want to re...

Re: memory leak while encoding
Calling "delete filePtr.getDataset();" is certainly not a good idea, as the ownership of the internally managed dataset pointer is still with the DcmFileFormat instance. Instead, you should either call "delete filePtr.getAndRemoveDataset();" or "filePtr.clear();". By th...
