Re: How to convert a dicom file from RGB format into MONOCHROME2?

I have a multi-frame image of RGB format.
Does DicomImage::createMonochromeImage() convert all the frames from RGB to MONOCHROME2?

Re: Memory Mapped file support

Hi Jörg,

I am not able to get an complete picture on my requirement 'create the whole image in memory and send this to DICOM server'. My apologies.

You mean, after the store is initiated, create the image, add tile by tile to the DICOM image and and send these chunks of image data to DICOM server ?

Re: Memory Mapped file support

Thanks Jörg & Michael. This gives some idea on how to proceed. Our workflow is, the client requests to transfer a huge pathology image to a DICOM server in Whole Slide Image IOD. Client gives all the tiles data to DCMTK DLL, then DCMTK DLL collects all the tiles data, add them to the target DICO...

Memory Mapped file support

Hi, we are creating a huge DICOM image (Whole Slide DICOM image IOD), which would be bigger than the virtual memory available. Does DCMTK support or have classes which can help (similar to Memory Mapped Files of Windows) ?

Re: 0xa900: Error: DataSetDoesNotMatchSOPClass

Hi Michael, Yes. True. strscp does not change the SOP Instance UID. We were able to locate what changes the UID. The below is the partial client code. 'chooseRepresentation' function is changing it. But not sure why it changes the UID. The filexfer is 'Little Endian Explicit' and netTransfer.getXfer...

Re: 0xa900: Error: DataSetDoesNotMatchSOPClass

Thank you Michael for your quick response. At the client side, the Affected SOP Instance UID is copied from the DICOM instance which we want to transfer. In this case it is ==> 1.2.276.0.118.696685194.21556.1682492941.488 I checked the client side, and could confirm that, the Affected SOP Instance a...

Re: create one Dicom file from multiple images

Hi, i know this is a quite old topic, but we implemented a patch for this functionality a few weeks ago. The patch was implemented on top of repo version "9a80174a27877f1b32d6c4b7a6f1e6cc0fffd6c6". I have not applied and tested it on the latest repository version. I also sent this patch t...

Windows bitmap (HBITMAP) to DICOM Image.

I am trying to convert a Pathology based Cell image to DICOM image and send to PACS. I have an existing implementation, written in Delphi, which converts the Cell's pixel data into an TBitmap, which is nothing but an encapsulation of Window's HBITMAP. So, how can i use HBITMAP object (memory pointer...

Re: How to set Implementation class UID and Version name.

Thanks Michael.

The reason makes me clear, and would like to retain the DCMTK provided constants in our design as well, to take advantage for work around's in case of DCMTK errors !!.

We are validating our MWL service using DVTK. In the validation session, we need to set Implementation Class UID and Implementation Version Name. During association, we use function, ASC_createAssociationParameters, in assoc.cc, we can only use the DCMTK's UID and Version name, strncpy((*params)->ou...
